Evening Folks

i have some weird issues with my PC after upgrading to the AM5 Platform.

I started off with a new build,

Ryzen 5 7600X
TUF B650 Plus Wifi Motherboard
16GB DDR5 Kingston Fury Beast
RX 6800 XT

I had crashes, BSOD, and whilst playing MW2 random crashes from the game too.
I had ran the Inbuilt Memtest on windows, and it had shown hardware issues.
I can put in 1 stick of RAM and it would pass, swap them around and again it would pass.
Put them both back in, and it would pass, but after a reboot it might fail.

So I asked Amazon for a replacement set, this arrived a day after.
After a few hours the same Issue appeared again, but happened less often.

A few days later it was still happening so I got a replacement Motherboard, Switched to the MSI Tomahawk B650.
All was fine for a week, with the very odd system instability, or game crash.

Yesterday the crashes were coming thick and fast not in windows but in MW2, issues pointed to Memory again,
after running Memtest again it had shown Hardware Issues.

So yesterday evening I ordered another set of RAM, but upped it to 32Gb, and went for Corsair Vengence, optimised for AMD.

I managed to get a first boot and it was fine, but after restarting the computer it would not POST, the Motherboard
LED would go through the motions, RED, Yellow, White, Green, Off and computer would be black screen.

I tried to set Expo mode 1, but again wouldnt post. I've had to remove the battery and re insert to get the PC on.

So motherboard has been changed, RAM has been changed 3 times. Non of the Event Viewer issues point to a GPU issue,
its possible, but in regards to MW2, it points to a randgrid.sys, which I believe is the Anti-Cheat.

Not really fussed in regards to MW2, but I would like to get to the bottom of the General System Instability.

Has anyone else had issues when upgrading to the AM5 platform, in regards to RAM, or processor issues?
 
Early AM4 stuff seemed to be sensitive to BIOS updates, I wonder if AM5 is similar. Although there were newer biases released as my x470 progressed, some of the newest release ones would cause instability similar to what you describe and you would sometimes have to drop back to older versions … particularly when running the memory at its DOCP setting.

All that said, you’ve changed everything … except the CPU … which throughout it all has been present for every problem.

What about running it without the GPU, probably won't play any games but will at least confirm some stability.

I've also just recently built the 7600X in an Aorus Elite AX B650, although haven't moved my GPU over yet but have been running for a few hours to do setup and it's been fine.

I will give it a bash today and see if running on the IGPU makes any difference. Its gonna be a strange one indeed as right now the PC booted up first time, where yesterday I had to take the battery out every 2nd reboot.
In regards to the GPU, I can throw 1440p and 4k gaming at it, and it will all play fine, I can throw any benchmark and it will pass. Would this not rule out the GPU at fault?
I have read a few comments on Reddit and other places where people on AM5 and Intel when they first brought out DDR5 had to do their own timings for the RAM, rather than rely on Auto or XMP,

is this something known about within the community?
Should I go down this route and see if it makes much of a difference?
Compared to Manually, would having it on Auto cause instability Issues?

Cheers for the replies folks :)
 
@pr0xibus

Theorectilly stressing the system should rule things out but things are just not that simple with a pc. Another option if you think its the cpu is to buy another and run It for a week then send it back

Did you try runing the memory at stock config ? Sure there's been known issuies with memory timmings but bios u0dates isually resolve that.

To be honest I've not touched anything RAM related in the bios, I usually just keep it stock, or I did on AM4 and had planned to on AM5,

My brother when he first went to DDR5 on his Intel platform he had issues ROUGHLY the same as me, he had to put his Timings in manually and not auto, apparently that sorted the issue,
for him.
Yeah I'd expect BIOS updates to fix relevant issues etc, but this is the first time I jump on a new Platform so early, previously I was on FX series when AM4 was still a year old. Maybe I just need to wait for newer updates on the BIOS and see if that fixes any issues.
Cheers for the replies :) I will update later today to hopefully rule out the GPU
 
@pr0xibus did you perform a clean install of windows 11 when you changed to am5, what system were you runing before, intel or amd?, am5 is a fair bit diffrent from older platforms so its important to re-install windows so there are no driver conflicts, insure expo (xmp) is enabled too. (you'll have to wait at least 5mins for memory training to complete, it may finish sooner code 15 should appear or a yellow led will remain on until it completes)

do you get crashes in other games?, the last driver to come out for 6000 series was 22.11.2, possible that driver is too old for mw2 which may explain the crashes in the game, if your on a older driver than mentioned above, update to the latest and try again, if you get the same thing happening, well theres's no easy way to put it but a new gpu may be needed if mw2 is your main game

Morning
Yeah this was a brand new Parts and Installation, previously running AM4, but sold the whole PC to upgrade to AM5.
When I try to enable XMP I previously waited just over 30 minutes, then gave up and removed the battery, that was on the Kingston DDR5 Fury Beast, I will double check with the Corsair ven...
I had crashes on 2 games, MW2 and High On Life, MW2 more so than the former.

Latest driver was 2022/11 I think, which I have installed, the next driver for 6* series will be Feb, as the Next driver I believe is only updates for 7* series.
None of the Memory dumps point to an AMD issue, it always seems to point to a Game Issue I.e.

MW2 points to randgrid.sys which I believe is the anti cheat (I also believe this is kernel level, but dont know the ins and outs of this), or
Attempt to free pool with invalid address (or corruption in pool header) or
IRQ_NOT_LESS_OR_EQUAL.
The memory almost always comes up as having issues using Windows memory Diagnostic, this is the reason why I kinda stayed away from a GPU issue.
BUT I also have had crashes just as I log into windows, or on Desktop.
Just a weird one indeed :)
 
is your ram on the qvl list of supported modules for your motherboard, 30mins is a bit excessive to wait for memory training, when i booted my am5 build i had to wait around 2 mins after enabling expo, i run corsair dominator plats 6000mhz, what speed ram are you running?
 
have you got any led's showing (yellow for ram) or anything else?

when you enabled expo did you check the ram voltage was set correctly?, if not reset cmos and head back in enable expo again but before exiting check you ram voltage is setup correctly, you can find this info on the serial number of the ram stick, the weird behavoir your describing in windows sugests the ram to me, if not running at rated speed it can cause all sorts of problems and performance will be pretty low. have you updated your bios on the new board?
