Yes, I typoed. It is 4 x 16GB (model # is F4-3000-C16-16GISB), total of 64GB. 4 modules, D2, B2, A2, B2 slots as recommended by the board. Current RAM Clock speed is set to "Auto", showing 1067 in Ryzen Master so 2133 I guess? Should I manually bump this up to DDR4-3000 in the bios?
Since all the processing work in this machine is done by the CPU (this is a compute box, not a gaming machine), the GPU is only a GT1030 - maximum of 50W. The motherboard has both CPU_PWR1 connectors plugged in. There is no cooling for the four chips (I presume you mean memory modules). I did try aiming a desk fan in there to see if it helps, but it didn't. The crashes don't appear to be load related. Sometimes, the crash will happen when the system is at idle, other times it will happen when the system is running a render job. But the most reliable way to make it crash seems to be to start a render job. Of the 8 machines, some will crash in as little as 10 minutes. Other times I've seen them go for up to 48 hours.
Finally, on closer inspection, I have noticed that my "PCIE_PWR1" connector on the motherboard are not connected. I see your motherboard also has one - do you have it hooked up? This could potentially be the issue?
The bottom line is none of my machines are stable unfortunately. I expect them to run for weeks at 100% load (as our Intel i9s do).
"Finally, on closer inspection, I have noticed that my "PCIE_PWR1" connector on the motherboard are not connected. I see your motherboard also has one - do you have it hooked up? This could potentially be the issue?"
Absolutely! You are talking about this right? BOTH need to be connected to a power supply with the appropriate supply outlets.
Is your one hooked up? I see your board has this connector too, in addition to the CPU_PWR1 and CPU_PWR2 as well. Only, yours is on the bottom left.
liamretrams, I tried to be subtle about it but I am almost sure you need a bigger power supply. Please get one PS of at least 1000 Watts. I have seen this power shortage more than once. Is your memory on the QVL list? Please leave it at SPD speed. When this is settled, you can try an XMP if you like. My PCIe_PWR1 is plugged but it is really not needed. It should be used for multiple GPU setups. All of the CPU power connectors should fully populated - 2x8 pin, not anything less. I was not talking about cooler for the memory but for the CPU. When I selected my CPU cooler, I was careful to select one that specifically said it covered all four chips in the processor module. Older coolers (prior to TR) do not and should be avoided. Please run CPU-Z and post a screehshot:
You can drag-n-drop the image here. I want to see your AGESA.
I strongly recommend a stronger PS. Thanks and enjoy, John.
Hi, I posted my CPU-Z info already. I will see about a larger PSU and QVL RAM. I'll attach it again to the end of ths post.
I distinctly remember when this happened, we went back to our hardware vendor. They gave me some QVL ram, but it did NOT address the crashing issue.
The problem is the fault is difficult to reproduce. Sometimes it will crash in 5 minutes just sitting on desktop, other times it will run for 48 hours without issue, and everything in between.
I do run have a 2990WX, running on a 1000 watt PSU, but it also have a 1080ti, overclock my power limit to 300 watts (vs. default 250w), have 2 nvme drives, 1 mechanical HD, 5 fans and an AIO.
When I was tweaking my OC, I monitored the wattage I was pulling from the wall socket and it maxes out at 460 watts on average using a real world v-ray scene render that lasts 1 hour with my OC settings. I could put a higher OC setting but my cooling wasn't up to snuff and the power draw was getting too high (550watts at a 350 power ceiling setting). I just settled for a mild 300 watt OC and I pull in around 5300 in Cinebench. To be honest though the OC does not affect my real world renders that much, it just shaved off like 3 minutes of a 60~ render.
Anyway, the PSU can definitely be a cause but liamretans said that his machine would hang/crash doing nothing, just being on the desktop. That sort of makes it less likely to be a psu or a cooling problem because his machine wasn't even under load when it crashes. This makes it seem more like a hardware incompatibility problem or a setup problem with the OS. Not all GSkill RAM is agreeable to Threadripper, especially the 32 core one.
Here is my system:
AMD 2990WX
MSI Meg Creation X399
GSkill F4-2933C16Q2-128GTZRX (this is a solid 128 GB kit) - runs at 2933 MHz
EVGA 1080Ti Black Edition
Samsung EVO 970 500GB nvme
EVGA P2 1000wat Platinum PSU
Here is my RAM:
As you cane see my motherboard (and processor) is in the QVL list of GSkill. Strangely enough though this RAM is not in the MSi Meg QVL list, but as I said, at least one of them should be in some sort of QVL list.
Getting 2 X 32 GB kits (where the 32 GB kit is QVL listed) does not necessarily mean it will work when you use 2 kits together to form 64GB total. From what I have heard, the 2990wx is very finicky with RAM.
If you have the same RAM Memory installed on all your computers, it might not be compatible according to MSI Support on RAM Memory for the Ryzen 2xxx WX Series QVL List. It only shows two G-Skill RAM: Support For X399 SLI PLUS | Motherboard - The world leader in motherboard design | MSI Global
Ryzen CPU are pretty sensitive to the type of RAM installed which is why you should follow the QVL list from your Motherboard's support. The Ram you have is Dual Channel RAM modules: https://www.gskill.com/en/product/f4-3000c16d-16gisb
The F4-2400 RAM (1.20 vdc) is Dual Channel and the F4-3200(1.35 vdc) is Quad Channel.
According to MSI Support concerning QVL List for Storage there is only one Sandisk SATA listed: Support For X399 SLI PLUS | Motherboard - The world leader in motherboard design | MSI Global
All this is just for your information only in case you weren't aware of it.
Your problem is probably to do with the CPU using all 32 cores. Found this website that is having freezes while rendering using Chaos software: https://forums.chaosgroup.com/forum/v-ray-for-3ds-max-forums/v-ray-for-3ds-max-problems/1016182-amd-...
Try using less core on the CPU when you are rendering and see if it continues to crash. In Chaos Rendering you can set how many cores you want the CPU to use as an example.
From what I have read, if you set in Ryzen Master to Legacy mode it will automatically disable a certain amount of CPU cores to make it more compatible with older games or programs.
By reducing the amount of cores also reduces the amount of power used which could indicate a PSU not strong enough to power all 32 cores under heavy loads.

If possible you can use a less powerful Ryzen with 24 cores and see if it crashes also.
Like this?
Here's my screenshot of Thaipoon Burner. Ryzen Master screenshot forthcoming.
RAM speeds in the BIOS are set to "Auto", it has settled on 1066 (2133).
And here's a screenshot of RM while rendering a scene. I'm using 3DS Max/Corona.
This has been going since yesterday - so nearly 18 hours now. As I mentioned, the crashing is very inconsistent. Sometimes it can't make it 18 minutes before the screen goes black. Other times, its going for a day or two without issue.
The thing is sometimes mine will crash when it's on the desktop with nothing happening. But it definitely crashes far more often under load.
I've disabled 50% of the cores in RM (see screenshot) using the "1/2 legacy compatibility mode", and the render has been running for 1 hour now, none of the 8 machines have crashed.
Trawling the cgsociety, vray and chaos group forums, I am finding that there are a TON of people with similar issues but this issue isn't isolated to Ryzen 2990WX. It seems more tied into how NUMA nodes etc work. People with more than 1 socket keep coming up in my searches. While ryzen doesn't have more than 1 socket, the effective setup is simliar - multiple NUMA nodes and a higher core count by a significant amount.
I will report back in 24 hours.
