[RAM] DDR4 3200 Mhz speed not working

[moproblems99]

Hmmm alright, thank you for the suggestion. I will try out the memtest and post results.



Thanks man, but I really want to keep my RGB set complete



I initially had a Gigabyte 5700 XT OC but I swapped it out for a Sapphire 5700 XT Nitro+. I have no issues and the most recent drivers installed.

I did a memory diagnostics test again and this time I got received a message after the restart. Does this mean I have a faulty set of RAM or perhaps I didn't install it correctly? Also, running on 1.4V with XMP enabled. The thing is, if I just turn off XMP all the problems go away, however my RAM speed is clocked at 2133mhz then.

It sounds like you need to rma them if you still can.

Again, as people are trying to explain to you, this might simply be a compatibility issue.
You really don't want to run your RAM at 2133MHz with a Ryzen, it's going to bottleneck your system.
Ideally, you should be somewhere between 3600-3800MHz, depending on what your CPU can do.
Even 3200MHz is a tad on the slow side, even though it's what AMD suggests as the highest "non overclocked" speed.

Just return the RAM and find something else, as your board maker clearly hasn't implemented support for the RAM you have.

I agree, me and @TheLostSwede both have the Patriot Viper Steel 3600mhz and they are quite good and cheap. Use the Ryzen Mem calculator that you can download from the website and we can even help you set the settings.

The only downside that the Ryzen setups have is that you need to input the RAM config manually in the BIOS to get the best performance and stability. This is not too difficult but I would understand the frustration of not being able to just enable the XMP and be done.

Try and disable the Hardware Acceleration on Firefox and Discord (if you use it). Changing the 5700XT to 2070 Super and the RAM to Patriot solved my issues which were very similar to yours.

Hmmm I see, I haven't done anything with my CPU yet just running on stock, but I guess I need to get faster RAM then. I will take this into consideration mate thanks!

Yea I hoped it would be plug n play and I have no experience with fiddling with RAM settings in the BIOS. Unfortunately, the hardware acceleration does nothing for me. Also, I don't think I will swap to the 2070S (performance per buck story).

So, now that I will replace my set what do I look for? Normally, I just look at speed and size (GB's) and a bit of aesthetics. Now, I see there is cas latency and all that good stuff I know nothing about.

Need, no, but it's a huge difference between 2133MHz and 3200MHz, whereas there's a smaller difference going faster. However, ideally, you want to run the memory controller and Infinity Fabric at half the memory speed for the best performance once you hit 3600MHz+, as this tends to get you a performance boost.
Note that most RAM tends to have a certain level of "flexibility" when it comes to clock speeds, for example, my modules are sold as 3600MHz, but they operate just fine at 3800MHz with a minor Voltage increase. That said, I also run them at slightly tighter timings as well. Obviously YMMV depending on the RAM and there's no guarantee how much faster they'll run, but most high-end modules tend to be able to overclock by 100-200MHz at the very least.

The G.Skill modules should be fine, it seems to be what a lot of people are using with their Ryzen rigs, although I'm not sure if it's worth paying extra for the Neo's with Ryzen 3000. Then again, as some people have pointed out, maybe check the QVL.

Personally I don't use RAM that's on the QVL, but it's possible I've just been lucky. That said, my previous system had a lot of issues with the Corsair LPX modules I had and I couldn't get them running at the rated 3200MHz clocks on this rig either. They were using older Hynix E-dies though, which are apparently not a good match with Ryzen in general.

This might get you a bit of an idea what different speeds can do and it doesn't start as low as 2133MHz...

Alright, so I've checked under memory QVL (matisse) and I see the G.Skill 3600mhz 8/16GB in there. The white set of G.Skill DDR4 RAM is called G.Skill Trident Z Neo F4-3600C18D-16GTZN, but I can't find that one in the list. However, G.Skill Trident Z RGB F4-3600C16D-16GTZR is on the list, but it's the black version. I assume there is no diference between the white and the black version?

That is the best choice I think for the RAM

Thanks, I think the G.Skill series should be sufficient for my build.

For anyone who isn’t interested in manually tightening timings and adjusting voltages, a 3600MHz XMP kit like this one or a high-quality 3200MHz kit is the obvious choice. According to GamerNexus, a 3600mhz kit like the G.Skill Trident Z NEO is fine I guess. I don't want to do anything in settings for the RAM. If the RAM runs at 3600mhz stable during games and streaming then I'm good.


I found 2 G.Skill Trident Z NEO sets.

Option 1: CAS 16 // true latency 8,89ns
Option 2: CAS 18 // true latency 10,00 ns (extra information on the retail site - optimised for AMD Ryzen 3000 and AMD X570 18-22-22-42)

So, option 2 guys? The price is nearly identical.

Pretty much worthless for AsRock... You cant trust it. A lot modules not in QVL works fine and a lot that are in there dont work.
Its turns out that are copy/paste lists. There is more chance to find what works on DRAM vendor than AsRock.

That's sort of the problem with AMD boards, XMP is an Intel thing and it's not guaranteed to work on AMD boards.
It seems to work in 70-80% of cases, but no-one can promise you it'll work.
Also, changing the settings is pretty straight forward these days.

Option 1 is much better, CAS 16 is significantly better than CAS 18 and the rest of the timings for the second set is terrible.
I run 16-19-16-19-36, which at least some people here think is slow...
It might not seem like much, but it makes a big difference. "Fancy" RAM these days is CAS 14.
Also, ideally get single sided modules, they tend to have better compatibility across all platforms.

 

[moproblems99]

I have Neos in my build and they work fine with my 3900x. It was the 32gb 3600 cl16 set. They appear to be Hynix CJR.

Aight, I checked the G.Skill configurator and I found that Trident Z Neo F4-3200C16D-16GTZN is compatible.

Ah I didn't know that XMP is an Intel thing

My previous build was Intel oriented and the XMP worked perfectly fine, so it might be interfer with my AMD-based build this time.

Basically, I have the choice between 3600mhz (cas18) and 3200mhz (cas16). Should I still get the 3200mhz?

I have Neos in my build and they work fine with my 3900x. It was the 32gb 3600 cl16 set. They appear to be Hynix CJR.

Thanks for your input man. I have to decide between 2 products.

G.Skill Trident Z Neo F4-3600C18D-16GTZN - 16 GB - CAS 18 - 3600mhz (18-22-22-42)

or

G.Skill Trident Z Neo F4-3200C16D-16GTZN - 16 GB - CAS 16 - 3200mhz (16-18-18-38)

This might give you some further food for though.

AMD Zen 2 Memory Performance Scaling with Ryzen 9 3900X

We take a close look at memory scaling on AMD's new Zen 2 Ryzen 3900X, testing both application and gaming performance at seven different memory speed and timing combinations ranging from 2400 MHz all the way up to 4000 MHz.

www.techpowerup.com

What to get, depends on what you're going to use your PC for.
I'd say the 3600 kit, as often higher clocks gives you better performance and there's a chance you can tune those timings a bit.

Seriously, you should consider doing a little bit of manual tuning, it's really not very hard for the key 6-7 settings that matter.
If the memory calculator seems overwhelming, keep in mind that most of those settings are fine on auto. Beyond the ones listed in the memory specs, the only other setting that really matters when it comes to performance is Trfc. Obviously setting the correct Voltage matters as well. Pretty much everything else can be left on auto.

I should add that it seems like AMD's memory controller, at least from what I have seen based on user reports, can handle tighter latencies than Intel's equivalent. However, it also seems that uneven CAS latencies aren't popular with AMD's memory controller.

I mostly play games (1440p) and sometimes stream, therefore I don't think I need ultra fast RAM. 3200mhz seems the suitable option for me. I never done manual tuning for RAM; I'm willing to learn and try it out.

Did you read any of the links I sent? In all of those, 3600MHz RAM comes out on top of 3200MHz RAM.
Neither is ultrafast, you have to go over 4000MHz to talk ultrafast these days. I mean, some companies are even peddling super expensive 5000MHz+ RAM these days, but that's just silly.
It's also no real point going over 3800MHz on AMD, as then the Infinity Fabric drops down to 2:1 ratio, which means everything that goes through that bus runs slower.
With 3800MHz memory, the IF runs at 1900MHz, but go to 4000MHz and it drops to 1000MHz, which is not what you want.

Throw up a couple of screenshots of the memory settings in your UEFI and I'm sure someone here can help you.
These days, if you plug in a USB drive to a port on your board (or case) you can normally grab screenshots in the UEFI by pressing F12 or something similar.

Ah yea my bad. I meant when I originally build my PC i thought 3200mhz was fine. Alright the 3600mhz RAM is thus the sweet spot for me.

I assume I should post the memory settings after I got new RAM. Thank you for your help man! Greatly appreciated.

You can try XMP to start with, it will either work, or it won't. Obviously it doesn't with your current memory.
But yeah, run the DRAM Calculator and then throw up some screenshots of that and the UEFI and we'll help you figure out what goes where.

Hey man. I just installed the G.Skill modules and they are looking great! I did a memory diagnostics test on Windows and this time I had no hardware problems. I've changed the XMP settings on and its running at 3600mhz and 1.35V.

If you don't care about eeking every last bit out then just set xmp and make sure fclck/if frequency is set to half of mem speed. If ram is 3600 then set infinity fabric to 1800 and call it day.

Once you hit 3600 1:1 then you are talking about 1-2% by fiddling any further.

If it runs stable at 3600mhz then I'm fine with it. Alright where can I find the infinity fabric? Is that in BIOS?

You don't have to change it as 3600mhz auto sets the fabric to ideal ratio. You can check it with any diagnostics app or ryzen master.

Not sure what you're trying to accomplish by using Windows hardware diagnostics. As people have suggested, get memtest86. Put it on a USB and boot from it into Memtest. Run it continuous for anywhere between 4-8 rounds of testing. Go take a shower, watch some TV, go make yourself some food. Come back and if it's all in the clear, you're golden.

Make sure your XMP is stable at 3600/16 through Memtest before you start going off and using the calculator to tweak your timings.
