New AM5 build [help]

[bluntzera]

Good evening, everyone! How are you all?

I'm new to the forum, so I thought I'd start by introducing myself to give you some context for helping me with this build.

I currently work as a flight attendant in offshore aviation, transporting oil rig workers. I live in Brazil, where the currency exchange rate from Brazilian Reais to USD is experiencing its worst crisis ever.

This month, my PC setup completely died. I believe both my PSU and motherboard have failed. I tried booting my mainboard with a friend's PSU, and I managed to access the BIOS once, but after restarting a few times, I couldn't even get back to the BIOS again. So, while I’m not entirely sure the motherboard is dead, I strongly suspect it.

Here’s my current (now non-functional) setup:
Processor: Intel i7 9700K
Motherboard: MSI Z390 Gaming Edge Graphics Card: EVGA RTX 2070 Black
Storage: Samsung 1TB SSD
Power Supply Unit: Corsair 750W RMx Monitor: 27" MSI 1440p G-Sync

Prices for older-generation z390 motherboards in Brazil are very high, so I’m planning to build a new setup using AMD’s AM5 chipset.

Now, on to my questions about the parts for this new build:

1. **Processor:**
I’m considering the AMD 7800X3D, as my primary use case is gaming. However, I occasionally do 3D modeling in SolidWorks for 3D-printed parts and some mockup work in Photoshop. I’ve been following AMD’s reviews and noticed that the 7900X also caught my attention. In Brazil, it costs the same as the 7800X3D.

Based on my usage, it seems like the 7800X3D would be a better choice for gaming, right?

2. **Motherboard:**
This decision is proving to be the most challenging. Since I’ve always used Intel systems, filtering through AMD motherboards has been difficult. There are just too many options, and any chipset above the B650 is outrageously expensive in Brazil. Even high-end B650 boards are quite pricey.

I’ve watched tons of reviews and benchmarks, but I’m mainly relying on VRM quality to narrow down my choices. I know I should consider other features, but I’m feeling overwhelmed.

Budget isn’t an issue—I can afford the most expensive boards—but are they really necessary for my needs? At the end of the day, what matters most to me are durability, quality, and customer support. I want to buy the best motherboard based on community feedback.

3. **Memory Kits:**
Choosing RAM is another challenge. I don’t know which memory kits are recommended for this type of build. I’d love to get the fastest kit possible, but I prioritize stability.

My current (dead) PC has a 16GB TeamForce Xcalibur 3600MHz kit that’s incredibly fast, but I could never get it to run stably at the advertised speed. I ended up using it at 3200MHz (XMP default) because anything higher wasn’t stable.

In Brazil, it’s common to find sketchy Chinese memory brands, but I’d prefer spending a bit more on trusted brands like Corsair or GeIL that offer stability.

What memory kits should I consider for this build—32GB or 64GB? What speed and CL should I look for in DDR5 kits? Should they be EXPO-certified?

4. **SSD:**
What SSD should I choose? My current SSD is a Samsung 1TB 970 EVO Plus. These days, 1TB isn’t enough when I install three games from my Steam account plus apps like Photoshop, Illustrator, SolidWorks, Keyshot, and Orca Slicer for 3D printing.

I’d appreciate recommendations for SSDs with more capacity and higher performance.

**Additional Info:**
Most of the games I play are GPU-intensive, and my RTX 2070 may still be functional. I plan to save up for a GPU upgrade next year, as NVIDIA’s 40xx and 50xx series don’t seem appealing at the moment. I can wait to upgrade the GPU if it hasn’t died along with the motherboard.

Thanks so much in advance, everyone. Any guidance or input on the components would be a huge help!

I hope my English isn’t too rusty—if anything is unclear, please let me know, and I’ll do my best to explain better.

Greetings from Brazil

Do you have a web shop or something we could look at to try and figure out pricing where you are? Sometimes a good deal in one country is terrible in another.

I'm not sure what case or cooling you want or have access to so I just threw in a couple nice parts that are relatively cheap for full sized. I'm on my phone currently so sorry for a lack of some explanations.

^from US shops because pcpartpicker.com doesn't have Brazil as a location so again, I'm not sure if these are available.

I tried to pick the best price/performance motherboard I could based on what I see available.

For the 3d modeling you do, more memory is helpful so I went with the cheapest reputable kit of 64GB 6000-cl30 memory I could find with EXPO (which you want). My work laptop has 32GB of RAM and when I run Solidworks (just opening models and working on drawings), it has been getting close to 30GB lately. I think this laptop might have some kind of memory leak sometimes though...which I can't do anything to troubleshoot without admin privileges that my work doesn't provide, so I have no idea if that requirement is real, but that's why I picked you a 64GB kit. It's possible you might not need it, but I like Burt Gummer's quote here: "I'd rather have it and not need it than need it and not have it".

I picked the 1000W version of the power supply I own because reviews are good and it's worked great for me. The Pure Power 12 M line is cheaper and still reviews well, but it's less efficient. I like some of the Super Flower, Corsair, and Seasonic power supplies as well. The newer FSP Hydro Platinum supplies have been reviewing well lately too (not their older supplies as much). If you want to put some options out there we can weigh in on them. I went with 1000W as the minimum if you're going RTX 4090. If you're going with a lower power GPU for your future upgrade, you could drop down to an 850W psu for example. Right now you could use a 750W probably, but I always try to buy for the future as a good quality power supply should last you a long time.

For SSDs, I like the WD sn850x and Samsung 980/990 Pro models. I am using a Crucial T500 in a laptop and it seems to be performing very well, but their software sucks. I theoretically only need the software for firmware updates and there haven't been any for the 4TB one I have so I don't even need the software lol. There are other good ones out there, but I've had the best luck with Samsung and WD.

As for what CPU, I think you may see improvement from a 7900X in your other tasks, but gaming will suffer a little. That said, at 1440p the average performance difference of 7800x3d is probably not huge (like it could be at 1080p...if you're using a 4090). With your 2070 it won't matter in games at all and the difference could be small depending on what future gpu you go with. I'm also not sure how much your other software scales past 8 cores (a lot of them don't), so the performance difference there may be small. Then it comes down to looking at the price difference and deciding which small percentage difference is more important to you.

Edit (now that I'm on desktop): Some other case and cooler suggestions:
Fractal Pop XL Air
Antec Flux Pro
Fractal North XL
Corsair 5000D/7000D Airflow
Be Quiet! Light Base 600/900
Be Quiet! Dark Base Pro 901
Fractal Torrent (for airflow builds, not liquid cooled)
Peerless Assassin is another good air cooler and very cheap
Arctic Liquid Freezer line (iii is the latest), anything 280mm and up would definitely be more than adequate for a 7800X3D.
be quiet!'s new AIO has refill ports, which is a really nice feature for an AIO as you should be able to outlast the normal burn-out of pumps that happens when evaporation allows air into the loop and kills the pump.

7800X3D is a good all-rounder, especially for gaming. If you were only doing 3D modeling and PhotoShop I'd suggest the 7900X. However, the 7800X3D will run cooler and draw less power for what that's worth and it will still do well in your other tasks.

Budget isn’t an issue—I can afford the most expensive boards—but are they really necessary for my needs? At the end of the day, what matters most to me are durability, quality, and customer support. I want to buy the best motherboard based on community feedback.

Expensive motherboards are very unnecessary these days. A well-rounded budget board will work fine.

What memory kits should I consider for this build—32GB or 64GB? What speed and CL should I look for in DDR5 kits? Should they be EXPO-certified?

32 GB should be sufficient for the vast majority of tasks on a PC. I only think 64 GB is necessary for video rendering or simulation purposes. It's a good idea to look for EXPO-certified kits as they typically work the best with AM5 platforms.

What SSD should I choose? My current SSD is a Samsung 1TB 970 EVO Plus. These days, 1TB isn’t enough when I install three games from my Steam account plus apps like Photoshop, Illustrator, SolidWorks, Keyshot, and Orca Slicer for 3D printing.

I’d appreciate recommendations for SSDs with more capacity and higher performance.

@Bobaganoosh 's suggestions are good. Gen 4 should be plenty fast.

 

[HD64G]

Your CPU choice is solid. My opinion goes to MSI B650 Tomahawk for motherboard. WD Black 770 or 850 for NVME. GSkill F5-6000J3636F16GX2-FX5 for RAM.

@bluntzera

Hello,

For 2TB M.2 SSDs you could also look at Kingston Fury Renegade and Crucial T500. It all depends on what is available in Brazil.
So you have a few options: Samsung 990 Pro, WD SN850X, Kingston Fury Renegade and Crucial T500. Next step is to check availability and price.

For RAM capacity you should know better than us based on your previous experience, if you do heavier stuff and multitask that will eat up RAM quickly. So you could benefit from 64 GB. However in the case that what you do now and what you (predict you) will do in the next several years will not require 64 GB then it's wasted money basically.
But since you can afford it and you're not on a tight budget then the safest bet would be to go with 64 GB and not worry in the future about being limited to 32 GB and then stress about managing your workflow in order to avoid memory swapping and all that.

Another case you could look at is Phanteks G400A, assuming it's available.

About the PSUs I would not pay more than $200 (USD) for a 1000W Gold unit. Check these if they're available:
Super Flower Leadex VII XG 1000W Gold (SF-1000F14XG)
Super Flower Leadex III Gold Up 1000W Gold (SF-1000F14GE)
Thermaltake Toughpower GF3 1000W Gold (PS-TPD-1000FNFAGE-4)

Firstly thanks a lot for your input. Now let's get in to answering your questions.

The most common and reliable PC parts here in Brazil are kabum.com.br / pichau.com.br and terabyteshop.com.br

Regarding the CPU, I will probably be okay with the 7800x3d. The other options such as the 9800x3d cost around 175usd more than the 7800x3d.

Now about the motherboard is overwhelming to find the right one. I would to get one with ez features such as display debug display. Clear Cmos and reset would also be very helpful. At a price point around 300/350usd I would expect most of them to have that but that unfortunately isn't the case nowadays.

A good onboard sound is also something I consider a lot. However I am trying to prioritize boards that won't slow down the primary PCIE gen 5, since I will be probably adding a newer gpu soon on this build. For now if my 2070 didn't die I will try to use it as I save up for a newer generation such as a 5070ti or a 5080 or something on the same range from an AMD gpu.

I will buy a newer SSD for the primary windows drive and will use my current Samsung 970 evo plus 1tb as a secondary storage to install another OS like Linux or use that for additional storage. So it might be wise to choose a board that won't slow down the main PCIE lanes if possible.

I have a deepcool AIO 240mm watercooler that will do for now, but I will surely upgrade the cooling later as I still have a lot of good powerful wc pumps around. It's just a matter of choosing g later a good cpu block and newer radiators.

Finding a good and reliable PSU won't to hard here. I am trying to follow the updated psu tier list and here we can find most corsair's units such as RMx models. Currently the 1000w (switch) models are a little cheaper than the traditional model with the standard (rear) Modular connectors.

Corsair is good here since they offer a good customer support and today I will start the RMA process for my dead 750w rmx as it is still under warranty. But anyways I will get another around 1000w just to be safe for when I upgrade the gpu.

Other brands such as Thermaltake, super flower, be quiet and FSP are a little rarer to find and they don't offer 10year warranty like Corsair does here. So I am trying to stick with PSUs listed on the tier list that will offer the best with a good warranty and support. Back then before this z390 setup that died I used to have an Enermax 1200w psu that was a monster on the previous setup, but these are also rare and expensive to find.

Regarding the case I haven't worried about it yet. I still have a Silverstone TJ07 in the garage I keep just in case, no pun intended. It's a very large case that already has an inverted tray to mount the CPU upside down. Might be a good candidate for this build but I could also buy something newer if the TJ07 doesn't work for this build.

Again thank you tons for all your input, tips and recommendations. I will definitely look into every single part you have suggested. I am also on my mobile here and I feel you, it's just very annoying to look up anything with patience and easy from the phone. Thanks a lot!!!!

7800X3D is a good all-rounder, especially for gaming. If you were only doing 3D modeling and PhotoShop I'd suggest the 7900X. However, the 7800X3D will run cooler and draw less power for what that's worth and it will still do well in your other tasks.

@Bobaganoosh 's suggestions are good. Gen 4 should be plenty fast.

Thank you Jak! The motherboards I have been searching for are the ones already reviewed or used for comparison here on techpowerup reviews. Here are some models I am considering:

Asus Rog Strix X870 - A
Asus Rog Strix X670e Crosshair Hero
Asus Rog Strix B850-F gaming wifi

Asrock boards are kinda varnish from stores and usually they have a very bad support here in Brazil.

Gigabyte or Aorus models are easier to find but the costumer support is a nightmare, so I am avoiding these since I have had terrible experiences with them before.

Msi options are a limited but they offer an okay support support. So I might consider them also. Currently the tomahawk models are very expensive like the new x870e Crosshair Hero.

But as I mentioned on the previous reply to @Bobaganoosh I am trying to filter for a board the will offer good features such as a good wifi, Bluetooth, good onboard sound and if possible debug display, clear cmos buttons are very helpful.

Durability and longevity do play a vital role. A good VRM section, PCIE gen 5 with a little as possible lane sharing would be ideal for this nearly high end build.

There are just to many options to choose and so many differences between them, hard not to miss something important.

Regarding the memory ans SSD I will take a look at your suggestions. I will most likely be buying the memory kit and SSD in USA and ask one of the helicopter captain that lives in Florida to bring them over.

Memory and SSD is significantly more expensive here and usually are components that rarely fault or brake. Also small parts that won't take too much space in his luggage.

The other parts I will be buying from here even though they will cost much more comparing to USA I will benefit from easier customer support and faster warranty if necessary.

Thank you!!!

Thanks Sol!

I will surely consider the 64gb kits for when using the PC to work on photoshop, 3d modeling and rendering.

Thanks for the PSU models recommendations. I will definitely dig onto those super flower Leadex models.

I looked at those three sites for motherboards and wow the prices are high. I think the MSI B650 Tomahawk is probably the best bang/buck that I saw on there, followed by Gigabyte Aorus Elite B650 and ASRock B650E PG Riptide WIFI. I saw in your other post that you don't like the support from those two brands, so I'm really not sure. There's the MSI Gaming Plus X870 to get you to PCIe 5.0, but it's a step-up in price. For another step up in price, there's the MSI MAG X870 Tomahawk Wifi that's probably the best one of the bunch, but you'd have to decide if the PCIE 5.0 speeds are worth the price. You won't notice it with your graphics card even if you go to a 5090. Check out the testing they've done, it's negligible over 4.0. If you needed the speed with an SSD for something, that would be the only reason I can see to get that and I think even some of the B650 boards have a 5.0 slot for one SSD.

I think your deepcool aio will be fine, but you can always buy something bigger if you want to bring the temperatures down or if you find you're throttling. The 7800X3D is probably the most efficient CPU you can buy, especially for gaming, but due to the IHS design, they still run warm. It's not bad, it's just different to get used to.

I get what you're saying on the power supplies. I'm surprised there's no 10 year warranty in Brazil because most of those have a 10 year warranty in other countries. I would just make sure you get a newer one that is rated ATX 3.0 and PCIe 5.0 or better. I wouldn't trust the older ones with the power spikes from newer GPUs and if you go with a newer high-end GPU you want to make sure they have the best 12V-2x6 connector/cables you can get.

Back to the topic: whatever @Bobaganoosh said is totally legit and I'd adhere to that to the letter.

Also there's absolutely no need to invest into PCI-e 5.0 for a gaming GPU. It barely makes any difference in outlier scenarios, and on average, it's 100% identical results no matter the GPU. And it'll stay that way for at least a decade more. PCI-e 4.0 is plenty.
7800X3D is so low in power requirements you can easily get away with whatever B650 motherboard there is on the market, unless you overclock the snot out of it.

Now talking GPUs. If your 2070 is alive then do absolutely nothing until it's totalled and if it's dead then...
I'd prefer a 4080 over a 5070 Ti even if a 4080 is more expensive. But not if much more expensive.
I'd prefer a 4090 over a 5080 period.
4070 Ti is a clear winner against 5070.
The reasoning:
• 4000 series is true and tested and 5000 series has design flaws and a ROP lottery.
• No 32-bit CUDA support for Blackwell. No idea if it's a problem for you but it's a feature limit so you should beware, or you might end up shooting your own foot.

I don't even remotely deem AMD worth purchasing but if you ever happen to disagree with me entirely then I have no other choice than to say that if a 9070 XT isn't >20% cheaper than a 4080 then I'd still pick a 4080. NVIDIA GPUs are better supported by professional software so you will find less glitches and more performance overall.

Welcome to the forum! Your English is just fine

I've read the suggestions in the thread, they're all pretty good. The 7800X3D is a solid choice, and if you can afford the Crosshair X670E Hero you mentioned, buy it, that is easily the best motherboard amongst the three you mentioned. As for the memory, G.Skill Trident Z5 Neo (tailor made for AMD platforms) is easy to find here, get a 6000 C28 or C30 kit, those will run very well with that configuration.

 

[dgianstefani]

The extra money for the 9800X3D is worth it.

I looked at those three sites for motherboards and wow the prices are high. I think the MSI B650 Tomahawk is probably the best bang/buck that I saw on there, followed by Gigabyte Aorus Elite B650 and ASRock B650E PG Riptide WIFI. I saw in your other post that you don't like the support from those two brands, so I'm really not sure. There's the MSI Gaming Plus X870 to get you to PCIe 5.0, but it's a step-up in price. For another step up in price, there's the MSI MAG X870 Tomahawk Wifi that's probably the best one of the bunch, but you'd have to decide if the PCIE 5.0 speeds are worth the price. You won't notice it with your graphics card even if you go to a 5090. Check out the testing they've done, it's negligible over 4.0. If you needed the speed with an SSD for something, that would be the only reason I can see to get that and I think even some of the B650 boards have a 5.0 slot for one SSD.

I think your deepcool aio will be fine, but you can always buy something bigger if you want to bring the temperatures down or if you find you're throttling. The 7800X3D is probably the most efficient CPU you can buy, especially for gaming, but due to the IHS design, they still run warm. It's not bad, it's just different to get used to.

I get what you're saying on the power supplies. I'm surprised there's no 10 year warranty in Brazil because most of those have a 10 year warranty in other countries. I would just make sure you get a newer one that is rated ATX 3.0 and PCIe 5.0 or better. I wouldn't trust the older ones with the power spikes from newer GPUs and if you go with a newer high-end GPU you want to make sure they have the best 12V-2x6 connector/cables you can get.

Yes very expensive! Besides the demand / availability issues the USD price is very high at the moment, such a bad luck my computer died amid this caos. Nor to mentioned the inflation has sky rocketed since Lula "won" the election. Ohhh well that's another talk. Let's get on topic.

Huge thanks for helping me filter down what's currently the best bang for bucks. The msi gaming plus x870 you quoted looks nice. The tomahawk won't do. Even though its just a motherboard and we probably won't be looking directly at it ever the design is soooo bad and those green accents just ewwwww, please no

I wouldn't mind adding another thousand or 2 just to see something prettier lol. But your point is absolutely right. I have been reading a little more about the 5.0 over the 4.0 and honestly I got to agree. It might be just fine with 4.0 gen for my needs. Amazing work @Bobaganoosh I am truthfully glad you helped filter down what's best bang for the bucks period.

Did you managed to see good psus? Only a few atx3.1 or "compatible atx3.1" units on the shops here huh? That's the reason I am making a list with all the suggestions and recommendations from you guys as well as keeping and eye from those units listed on the updated psu tier list including the reliable ATX3.1 from Cultists Network's website.

Trust me I will buy the best psu I can. I have always bought the best psus out there since my early days on s775 chipsets.

I think the 7800X3D is already the choice, since it will suit my needs and also be quite energy efficient over the 9800x3d or even the 9700x. I think we are solid on this choice.

The biggest challenge now was really filtering down the best mobo. I am nearly there and that will also help me choosing what memory to get as soon as I finally choose the best contender. I will call a friend tomorrow who is chief of marketing in pichau store in order to know if there an order for the Rog x670e Crosshair Hero that is out of stock but priced more expensive than the Rog Strix X870 - A also out of stock. The last know prices was 5.5k ish for the crosshair hero and around 4k for the strix x870-a.

No idea if they have order placed for these but I will try to call him tomorrow to find if these will be back and the estimated prices.

We are nearly there.
Fingers crossed

Thanks Macro!!!

I lived from 2006 to 2011 in Scotland, but we end up getting on with life and the English is getting very rusty unfortunately. I should be practicing more speaking and reading. Thanks for the compliment.

Regarding the CPU I'm also okay with the choice. Like @dgianstefani mentioned the 9800x3d is also a solid choice and I might even bug it instead if I find some promotion.

As I was saying on the previous reply to @Bobaganoosh I am reading more about the gen 5 vs gen 4 and you guys are absolutely right. I might be just fine even with a good mid to high end b650.

However I believe due to the demand and availability we are living at the moment even the prices of good b650 boards are crazy, often very near the price of top tier x670, x870 and b850 boards.

With that in mind I was thinking it wouldn't be so bad to spend more and future proofing the need to upgrade the mainboard soon. Either way I am keeping my eyes open for the parts suggested and this makes me understand much better reading about them all and that really does help!

Regarding the gpu I totally agree. I will try to use as much as can from this 2070. I would to download dome newer games like the new FS, asc shadows but that can also wait for a upcoming steam sale. Currently i was only playing far cry 6 that i just had downloaded the night prior to my PC die, dealta force and cs2 that I used play a lot before i rarely play anymore.

I agree the 4080 would be a great choice. Somehow the 4080's and 4090's series desapeared from the shelves here. I don't know if nvidia does that in purpose forcing stores to return the left over cards or if that is simply the high demand that every card was sold out. I now only see the 4060 cards in stock, but absolutely no 4070, 80 or 90 out here.

Thanks for stepping in!

*guys sorry if I am somewhat spamming the thread replying you guys individually. I'm on my Samsung old phone here and I couldn't figure how to multi reply/quote you in a single post.

I will call a friend that works in pichau tomorrow in order to find out if the have placed an order to restock these boards on the shop and possibly if he has an estimated price since the dollar just keeps on going.

I will check this memory kit also. I had a wicked look yesterday on some 6000 CL30 kits yesterday and woooow so expensive. I didn't see any CL28 though. I did see some 6400 kits that were almost the same price as the 6000 but those had very loose timings compared to other 6000 kits.

No worries! It's all good. The 6000-30 kits are sweet spot on AMD right now. Also word of advice on Pichau's own branded power supplies, they may be very attractively priced but the company only offers 1 year warranty, even in the Gold rated models like the Cluster.

Ugh, do me a favor, if you really know someone inside, while at it can you ask him what's the deal with the Palit Gamerock 5090s? I've been waiting for mine since January 30! Pichau's SAC has been completely useless and I am getting VERY frustrated by now.

They're even offering prebuilts with the 5090 and they haven't sent me my card. I'm at my wits' end!

Absolutely. I would never get those or even what is getting to be a norm here with some youtubers saying they are "teclab' approved.

I truly respect Ronaldo from Galax (rbuas) work and history but teclab "approved" means nothing. We need jonnyguru back!

Wow that situation about your gpu is bad. The guy I know is the marketing director. He probably won't be able to reply on that but I surely can talk to him about that.

If I got it correctly you purchased that on late January and still didn't receive it, right? Sac there was never great but doable. I personally never had any issues with them besides one time someone hacked my account on their site and tried purchasing a 30k pre-build PC. I was lucky I didn't have that money in the bank or I would have had a serious problem.

When that happened I called them personally to fix the website security since my email registered to their store wasn't hack, none of my emails or passwords were changed at all, so I assumed that had to be a security issue with their webstore.

They told me my computer probably had viruses or malicious softwares but I doubt it since none of my emails, social media, cards and etc were hacked or had the password changed. Well I was lucky because I didn't have that in the bank and I only saw that like weeks later when I tried to login and the password in pichau was changed but I managed to reset. I still have the address they tried to buy this pre built though.

Please count on me. I will make sure we talk about your situation and if he can't give me details and I'll make sure he gives me a number from somebody responsible for that.

Regarding the pre-builts with the 5090s I think those are somewhat locked and they cannot take a gpu from there to fix your situation. They probably sold you a gpu they didn't have in stock by mistake. However they should solve your issue asap as this already a 2month delay.

I think putting pressure on these large pichau/kabum Facebook groups will help a lot make it move faster since you have already contacted their support.

I would gather all the evidences, receipts, emails and etc and share that on those huge Facebook groups most of pichaus owners are there.

If you want I send you Juniors' Instagram as well as Hudson's (marketing) ig. I never had contact with the owners, but I will for sure help you out!

Sad to hear this happened though. I really hope they can fix this asap.

the asrock matx are the best am5 boards

AMD informed that Asrock AM5 boards have problems with some BIOS versions and not compatible RAM for now. Until that situation clears out, I suggest none buys from them AM5 motherboards.

 

[Bobaganoosh]

AMD informed that Asrock AM5 boards have problems with some BIOS versions and not compatible RAM for now. Until that situation clears out, I suggest none buys from them AM5 motherboards.

AMD's response shown in that article is about earlier issues with memory compatibility. The latest BIOS update from ASRock has supposedly fixed that issue.

There is also currently an issue with AM5 boards burning up CPUs, mostly 9000-X3D chips, but not entirely. It's also mostly ASRock boards, but not entirely. ASRock has responded to one failure case even though there are currently about 105 reports on Reddit of failed CPUs on ASRock boards.

The current Reddit-user-counted list:

Total found now potentially 115 dead 9800X3Ds, 93 on ASRock boards, 16 ASUS, 5 MSI, 1 Gigabyte. Also 10 other 9000 series CPU, all 10 on ASRock boards. Also 3 cases for the 9950X3D, 1 ASUS, 2 ASRock, all on X870 chipsets.

Dead 9800X3D tally based on chipset:

• B650: 17 cases
• B850: 40 cases
• X670: 7 cases
• X870: 51 cases

Reading through that list, it sounds to me like there's a BIOS setting that the motherboard manufacturers probably have cranked a little too high, ASRock more than the others...no idea right now if this is actually AMD's fault or the AIBs...likely a combination of both.

Things we don't know:
How many motherboards from each manufacturer are in circulation? ASRock has had a lot of availability and really competitive prices (as well as an increase in popularity the last couple years with ASUS going farther up in price and down in quality) so I'm curious what the percentage failure rates are with each board vendor per 9800-series in use (especially 9800X3D). I would guess ASRock's failure rate is quite a bit higher at this point lol, but it's possible it isn't as bad as it looks if they have 10-20X as many boards in the field. I have no idea what the real numbers are, I'm just saying we're missing some key data points here.
How many people have had failures (ASRock or otherwise) that haven't reported it on Reddit? This could be quite large possibly. I know a lot of people that just avoid Reddit like the plague.

All that said, I would think there will eventually be BIOS updates for everyone to address this issue...but I'd personally be a little bit hesitant to buy a 9000-X3D chip for a little while.

 

[fevgatos]

Just as funny as the burning 7800X3D. You can be sure I laughed about it and bought the B650M HDV at the time of its release – IMO the first reasonable AM5 motherboard. It was around the same time. I wouldn't suggest something I wouldn't do myself.

Such discussions without full statistics on how many people damage their hardware during assembly, how many each manufacturer sold are an insult to human intelligence and journalism. Waste of time.

Yeah! OP was even kind enough to offer to mediate with the shop I purchased my RTX 5090 from as he knows someone who works there personally... might take up on his offer if I'm unsuccessful dealing with them, right now I kind of got a lot on my plate. Done with my test week and not everything went smoothly, so next one I have to be extra prepared for. I also gotta do 50 more hours as a trainee law clerk until the end of May, so it's my schedule is packed next couple of weeks.

 

[anonuser57]

For motherboards hardware unboxed did testing on basically all the b650 boards and any they found that had vrms stay below 90C should be fine. Aside from that just look for the cheapest one with all the features you want.

Fo SSDs my recommendation is the cheapest 4TB nvme drive you can find from a reputable manufacturer. Techpowerup reviews have shown time and again that SSD performance doesn't make much difference for gaming and I don't think it affects your other applications either.

For memory 6000mhz CL32 I think is the sweet spot and I don't know how much memory you need.

I forgot to say thanks for the backup.

Also, I've been to Brazil twice, a few days each time for work, and didn't meet a rude or mean person the entire time I was there. Every person I met was friendly even if they didn't speak English. The only words I know in Portuguese are beer and bathroom (and "tu de bem?") lol. I even had what seemed to be a homeless guy stop a group of us Americans and ask if we were lost or needed directions as he was happy to point us in the right direction. Also, the restaurants we ate at were fantastic. One was obviously a Brazilian steak house (Churrascaria) and Golden Pizza, which was similar, but they bring endless pizzas of everything a human can imagine putting on a pizza and you just eat little slices of amazing pizza until you're about to explode...then you flip your token and they start bringing you dessert pizzas haha. I don't think I've eaten that much anywhere else in my life.

Anyway, AM5, yes...
