Hello,

I was wondering if anybody could help me. I recently formatted my PC and installed a new WD Black SN850 NVME.

I have issues whereby the system would judder with the sound also crackling as the juddering was happening, resulting in a BSOD.
At the time windows (fresh install) would not update so i put this down as a dodgy install of windows and formatted again a long with an update of the BIOS.

Anyway, I had 1 day whereby the system was flawless and ran absolutely perfectly (thinking the problem was solved) However, Tuesday night I experience the issue again juddering and then freezing completely and issuing a STOP CODE: WHEA_UNCORRECTABLE_ERROR.

I have noticed within the WD dashboard that the NVME is Gen4 compatible but only running in Gen3 and im not sure if this could be the problem? A friend of mine suggested running my GPU in Gen3 to see if this improves stability which to be honest, I haven't yet experienced the issue.

I have found conflicting information as to whether my CPU (3900x) supports Gen4, I am also wondering if this could be the issue?

System Specs below, any assistance would be greatly appreciated.

CPU:- Ryzen 3900x
Mobo:- Asus ROG Strix X570-I Gaming Mini ITX
Ram:- 32GB Team Group 8Pack editio @ 3600mhz
GPU:- Radeon Rx6800
PSU:- EVGA 850 Gold rated

3900x supports pcie4 it's on the amd website and one of you motherboard m2 slots is pcie3 , is the sn 850 in that one?

Bios up to date ?

I know the Chrisc in irl and have been trying to help him with this.

My conclusion was that there could be an issue with the PCIe gen the motherboard and the CPU.

The X570 gaming-i manual states that it only supports PCIex16 Gen 3 on Zen 2 chips (which the 3900x is), When we looked at GPUZ it was shown to be running at PCIex16 Gen 4, hence the decision to drop this back.

The weird thing is that the manual also states the board supports PCIe 4.0 x4 on M.2_1 for Zen 2 chips but I can't can seem to figure out why it defaults to Gen 3 or where to force the Gen 4 in bios.

Bios has been fully updated to the latest version. and right M2 slots are being used

We will probably catch up later tonight to probe a bit more and test but if anyone has any other suggestions we can look at its really helpful.

Plus I know that even though there is no performance loss at PCIe 3.0 for the GPU it really bugs him knowing its not 4.0
 
I don't understand what "juddering" refers to in the context of a PC.
All pcie compliant devices should down-train if the highest speed cannot be maintained and that should NOT be the cause.
Check if there was a memory dump from the BSOD and if so use WinDbg to get more information.
WHEA errors generally do point to hardware problems (and as noted a gen4 capable device running at gen3 is not a hardware problem in itself).

Thanks, ill do some more testing. The system ran flawlessly for 2yrs until I installed the new drive, this is what keeps pointing me towards it.

You didn't install a new graphics driver at this time, did you?

"AMD has acknowledged that its GPU drivers are also overclocking AMD CPUs in systems where Radeon and Ryzen are sharing space. This doesn’t appear to be happening in every case, but it may occur if you use one of AMD’s Radeon profiles. I happen to currently be running an RDNA2-powered Radeon 6800 XT and a 3900X, so I tested the problem out on my own system. The ability to control and monitor system clocks is intended as a feature of AMD’s driver software, but the point is not to deliberately overclock the end-users CPU without their knowledge.

I tested the bug in Horizon: Zero Dawn. I hadn’t previously selected a profile setting, so I kept everything on default for my first test. CPU clocks during this initial test were surprisingly low. My 3900X has a base clock of 3.8GHz and a boost clock of 4.6GHz. Games do not typically push the CPU to maximum, but the clock on my CPU fluctuated between 2.1GHz – 2.6GHz, with only occasional excursions.

I then went into AMD’s Profile Manager and selected “Gaming” as a profile setting. I did not yet have Ryzen Master installed on this system (thanks to a recent SSD death I am still rebuilding). This profile is listed as being for “Gamers who just want to play games” and states “We worry about the settings so you can focus on your gaming.” Switching to this profile had a marked impact on my CPU clock. When I booted HZO up again, system clocks shot up."

Still having the issue, ive reset the bios back to stock so no XMP etc. . the only thing that has changed is the new NVME, i think im going to take it out and reinstall windows to an older SSD.
