Windows 10
GPU: 7900XTX
CPU: 780X3D
EVGA 850w PSU
G.Skill 2x16gb DDR5-6000 CL36
Fresh build, no chance of driver contamination from previous hardware/software
*I have replaced the motherboard, the RAM, and the CPU*
All bios and drivers up to date
The issue: While gaming or while watching videos online, my PC will randomly freeze, one monitor will turn green and the other will go black. The system will hang in this estate for about 10-15 seconds, and then reboot. I have also noticed that after the system reboot, my sound will not work coming out of my speakers, only a headset. When I reboot the PC, the sound works fine. Although the crash can happen while no game is open, it primarily happens while playing games; Path of Exile and New World in this case. When the system crashes, there is no blue screen or error report. Event viewer simply shows that the PC was shutdown improperly. I have a HW info log from prior to a crash and leading up to the crash, but I don't see any "obvious" errors. I am NOT overclocking anything. In fact, I have not attempted to change any settings except trying out EXPO I for a few days
These crashes happen with EXPO on and off. I have run memTest86 and got 4/4 PASS on both sticks. I am able to run a complete cycle of cinebench, and I am able to run Heaven Benchmark. I have reinstalled Windows, I have repaired Windows. Temperatures on the GPU usually top out at 93C junction temp while gaming and 66C while idle. As I said, I have tested two 7800X3d CPU's and 2 different motherboards (ASUS x670e PRO WIFI and ASUS strix x670e-a gaming wifi). I have also tested two sets of RAM.
When the system fails touch around the cpu, memory to see if they are getting too hot. How many fans pushing air into the case? You want positive pressure in the case so to force air out of the case. In my case I have 9 fans pushing air in and one out the rear on a slower speed. Doing this allows for more cool air to reach the gpu and cpu and all of the heat sinks.
In Windows 11 I have had to un-tick on device drivers "allow computer to turn off to save energy". Thats networking, wifi, and any others you may find. You will have to go into device manager and check for that setting on device drivers. I also turned off fast boot in the UEFI. I was having issues with BSOD that now I have solved at least for the past few days.
I am having pretty much the same symptoms on 7900 GRE + 7950x3d using Arch Linux.
Right now the system is so unbelievably unstable, that to get it not crashing constantly, I had to set my display to 1600x900@60hz. Now it seems that I am able to write eg. this message before the whole screen turns into green and the system crashes.
A couple of months ago I was able to game with the system with only occasional crashes. I haven really used this PC for a while, but right now it's unusable.
My issues were about wrong configuration and use of a PCIe 4.0 riser cable. When I built my PC I did set the PCIe to be gen4 and everything worked, but since that I had a BIOS update which obviously wiped out my configuration, defaulting to auto, which is PCIe 5.0 / gen5. So the green screen crashes were due to using faster PCIe communication than the cable allowed. When the refresh rate was 60hz, I was not having problems, but HDMI 144hz was really unstable and display port (I guess trying to use 240hz) didn't even boot.
So if you are facing green screen crashes / unstable system, at least check that you don't use faster PCIe generation than your hardware supports.
Now my only real problem with AMD 7900 GRE is pretty terrible coil whine when on full load. Undervolting, underclocking etc. reduces the coil whine to bearable levels.
