4x sticks of DDR4 all bad at once?

Can you try 2400MHz@CL15-15-15-35 1.35V with only two dimms installed?

Great I think that will be incredibly helpful. When you pop it in use your new memory kit, do a quick 1 pass memtest86 just to make sure nothing goes horribly wrong then try booting the USB and installing windows. I'll be out for the day so good luck!

Tried to new CPU first before linux or playing with installers. System booted up to my Windows install, no issues, with the 2x 3600mhz RAM, did 4 reboots and all were back to normal. Swapped from the 3600mhz to the 4x 3000mhz in, same; no issues on booting and rebooted multiple times.
Something interesting: I ran the Cyberpunk benchmark (max settings w/path tracing 4k, DLSS at quality two times, and two more times with DLSS at balanced) on both the 3600mhz C18 RAM and the 3000mhz C15 RAM... the 3000mhz was 2-3 fps faster each time. I guess the 5900x prefers latency to speed? Definitely sending the 3600mhz RAM back for a refund, no point in keeping it if it's slower on top of my old RAM working.

Regardless, issue is definitely the CPU. Thank you all for the help! Now I get to deal with AMD CS and see if they suck

Part of me found it hard to accept that it was the CPU, only because I have not experienced a CPU failure.. everything else around a CPU has died, but never a CPU

But you did as everyone asked, and I cannot explain anything away so.. I guess you do learn something new every day

I guess it was the IMC degrading over time and it could no longer handle dual rank memory? I’m assuming that the GSkill Ripjaws that was working is single rank when I say that. I think I have a few months left on the warranty (6ish) so I hope AMD CS doesn’t suck lol

Ryzen Calculator isn't a great tool. It dont show the correct RTT Wr, Park, and Nom values when you have 4 single rank DIMM's installed.
To get the "correct" value you must switch to dual rank in the tool.

In what tool?

Ryzen calculator I thought was obsolete at this point,

This is I think why so many have issues on AM4 still, Ryzen calculator was great in the early zen 1 days, but once it stopped being updated, there was no real go to place I could find for configuring ram on AM4.

If you do mean ryzen calculator it is at least good you revealed you have to select dual rank, thank you. But are these values still optimal for zen 3 chips which have a different IMC to zen 1/+/2.

Bummer man. You did try a little more SOC voltage and VDDG IOD right? You shouldn't have to do any of that for running at 3200.. maybe for 1800/3600.. but not much over stock. I have been running 4 sticks of B-Die too, since the end of 2019 I think. I had a weird short in my system once, caused by a bad Molex.. I could not get anything stable, I though for sure my 5900X was done. AMD wanted me to run all kinds of tests and send screen shots. Before I did that I spent a couple of hours examining every wire, every splice I made to run the fans that I was running.. turns out a broken Molex was causing all kinds of havoc that you would not expect. I am not saying that's what happened to you, but it made me reach out to AMD. I still have it somewhere if I can find it I will take a pic lol

Electronics can be kinda funny that way..

Yea, I tried just about every suggestion in here with both the 3000mhz C15 and 3600mhz C18 RAM. The 3000mhz RAM was running fine for multiple years. Definitely not a short since the other CPU works now with any/all of the RAM that wouldn’t boot with the other CPU.

Latency tends to be more important in most cases but you want to maximise both as much as you can. Ideally you would want to get as fast as you can then tighten the timings as much as you can. Doing it "properly" is an hours/days long effort to do it right.

The other thing with AM4 is making sure Infinity Fabric speed is in lockstep with memory speed. Increasing speed beyond what IF can "support" will actually hurt you a lot in performance even though in theory its "faster".

I havent heard anything terribly bad about AMD CS as long as its in warranty they should honor it.

I think it's worth it to get a ZenTimings screenshot so we have a chance to see with the new CPU what the auto voltages are. We should just make sure your board is not putting too much SOC voltage on that might cause degradation in your new CPU's IMC. For example my ITX board for some reason want's to default 1.2v when it's unnecessary. Factor on top of that SOC LLC and who knows if it's been spiking above that and potentially contributed to the problem.

Just my opinion but I'd keep the 3600mhz kit (DDR4-3000 16GB CL15 to DDR4-3600 64GB CL18 why not?). You should have generally better CPU utilization with the faster kit but if in doubt run https://www.userbenchmark.com/ with the new and old memory and post the result links. This way we can compare the CPU utilization with the Memory performance together. Do you have plans to OC your ram? If your CPU can support 3733 or 3800 it would likely be easier with the new 2 dimm kit.

I don't know the full timings of both kits but they might be pretty close in terms of access time already. (DDR4-3000 CL15 kit vs. DDR4-3600 CL18 kit)
A few tweaks in voltage you might be able to tighten the 3600 timings closer to a CL16 kit.

Userbenchmark is typically pretty inaccurate unfortunately (iirc it started off fine but got ruined by fanboys over the years posting spoofed benches - this may not apply to RAM and just CPUs and GPUs though!).

The two RAMs in question are:
3600 18-22-22-42
vs
3000 15-17-17-35

Correct me if I’m wrong, but from my limited (recent) “looking into” this it seems that the CL timings of the 3000mhz vs the higher speed but slower timings of the 3600mhz brings them to roughly (theoretically) similar bandwidth/performance. What may be causing the consistent 2-3fps higher avg (I’m assuming at least) with the 3000mhz is that it’s 4x 8gb dual rank sticks vs 2x 32gb dual rank sticks with the 3600mhz: from what I could find, having the 4x dual rank sticks would run in quad rank and that’s likely giving the edge to the 3000mhz (assuming the quad rank bit is true lol ).
You’re both correct in that I could likely play around with the 3600mhz to get the timings lower to the point that it may beat the 3000mhz, even if I needed to drop it down to 3400mhz. But, then I start asking myself “how many hours am I going to need to spend playing around with and testing this, and for what percentage of performance increase in gaming over the already faster 3000mhz?”. So, for me personally, since I’m not trying to beat records, it seems not particularly worth it to not get the $150-ish back that I spent on the 64gb 3600mhz. Hopefully that makes sense.

Extremely good point on the ZenTimings and Infinity Fabric Speeds: I’ll post the info from ZenTimings later on today.

Thanks again, everyone!

Well that looks ok. Hopefully it was just some bad luck with the old CPU and nothing the board was doing. Glad it's all sorted finally.

Why do people keep trying to run Corsair Vengeance on AM4? You would think that after 6 years or problems that people have figured out that they are not compatible.

Not everyone goes to forums and reads about everyone else's problems before they have their own. It happens. Also, if neither Corsair nor AMD or motherboard vendors indicate it is a problem (or even take them off their QVL), why is it the fault of people building a system with parts that are supposed to work?

?
First I’m hearing of it, and the system was stable for multiple years with this RAM. It’s also on the QVL list for my motherboard. Seems like this is a faulty CPU more than the RAM.

Just want to give an update… and, I cannot stress this enough, AMD might have the absolute worst warranty CS I have ever dealt with. Holy F.
It’s email only for warranties: phone tech support has 0 access to warranty claims and cannot even check RMA status. The warranty CS email is being obviously outsourced, and they just copy and paste some script they have and do not address questions: I replied with all information and photos they asked for (despite all this information already sent as it was required to even request warranty services on their form), I resent all the information and asked a few questions regarding if they offered some type of expedited RMA (ie: I have a hold put on my CC and they send me a CPU then release the hold once they receive the defective product from me. ASUS, Corsair, EVGA, PNY, etc have all done this in the past when I’ve needed an RMA), and it’s fine if they don’t offer this but they didn’t even acknowledge my questions and literally sent me the same copy and pasted email asking for the info and pictures now a third time, I replied asking if any of the info I already sent was incorrect/incomplete and how I could fix it if so… they replied with the same copy and paste email. All responses from them are about a day apart and come between 1:30am-4am.
I have no idea how a company as large as AMD can have CS/warranty service this bad.

Isn't an option to contact the shop where you have bought the processor?

The CPU was purchased in May of 2021, it’s not a new CPU.

 

[VuurVOS]

Where did you buy the processor? Maybe the retailer is willing to send it back to the manufacturer since it is still in warranty.

My case last year:
MSI Motherboard was 2,5 years old and still in waranty of the manufacturer. Creating RMA is not possible for consumer at MSI in my part of the world.
Retailer didn't want to replace or refund it directly because it was older than 2 years.
The retailer created the RMA directly at MSI (special portal). After 3 attempts, MSI choose to refund the motherboard (MSI Service Center was very stubborn and sending it back unrepaired ).

Thank you, but unfortunately it was bought during the pandemic from AntOnline (even paid $50 over retail despite them being an authorized seller), I don't think their CS will be very receptive lol. I guess I'll give it a shot, though
