PC Drivers & Software

[Truyal]

Hello everyone,

I’ve recently encountered an issue with my PC and I hope you can help me. Since upgrading my CPU to a Ryzen 9 5900X, I’ve been experiencing occasional blue screens, especially during graphics-intensive games. The error code I’m seeing is: WHEA_UNCORRECTABLE_ERROR.

Interestingly, the problem mainly occurs under load, like while gaming, whereas the PC runs fairly stable during normal use. (Temperatures are all within normal ranges.)

Another detail: I updated my motherboard’s BIOS to the second newest version. The latest version causes the PC to not boot at all.

Does anyone have any idea what might be causing this issue? Perhaps someone has had similar experiences or knows where I can start troubleshooting.

Thank you in advance for your help!

Hi,

Have you removed the old CPU drivers from device manager? Did you cleared BIOS to defaults after new CPU? Do you run XMP/DOCP? If you do, disabled it for troubleshooting.

If nothing works you may want to consider OS reinstall.

Now as for hardware goes, what board exactly do you have? if you run that CPU on a more basic B450 you may run into problems due to weak VRM design.

Try disabling core boost for troubleshooting purposes.

And finally 600watts is a bit under for those specs, specially if 80plus bronze only and shady branding.

Good luck with the troubleshooting.

Is this your motherboard? MSI B450 Gaming Plus?

Because it only has 4+2 power phase, which is probably not adequate for a 5900X. The 5900X is a 105W TDP chip but stock power draw is realistically 130W+ with an all-core workload. Do you have an 8-pin CPU power connector to the board or just a 4-pin?

Also, you don't mention what cooler you are using, nor temps other than "normal ranges". AMD recommends a liquid cooler for this chip.

Finally you don't list what memory you're using other than "DDR4 64GB". Is that a 2x32GB? 4x16GB? What speed and timings? Have you verified it's on the motherboard QVL?
