I've got a problem I've never seen anyone describe before and am fairly stumped. I've built a new system with a B450 Tomahawk Max & XFX 5700xt raw ii graphics card. Current Adrenaline drivers. No OC, bios defaults. I've got independent power runs to the GPU with a 750W ps. Windows set up and installed fine, but once I installed the Adrenaline drivers the system became very unstable - rebooting when starting a game or moving windows around. I'd changed memory and power cabling before finding that if I undervolted the GPU, things stabilized.
Temps are good with the GPU at 40c idle & 70-75c during gaming. I DDU'd and reinstalled the graphics drivers a couple of times. Basically if I set 1900MHz / 960mv via Wattman, I can run GTA and a dozen other games for hours with every setting on ultra. Benchmarks are good. However, if "reset to factory defaults" or "auto" is selected in Wattman, the system will reboot within a minute or less. GPUZ shows the correct clock speeds when it's set to default. I figured I had a bad gfx card and RMA'd it - only to find that the brand new replacement (different manufacturing date) does the exact same thing: Stock voltage / no tuning to the GPU makes the system reboot.
I picked up an ATX power supply tester and everything checked out good (including both PCIe leads). I'd normally just move on and leave it at 1900mhz/960mv, but there's a period of time just after bootup or wake from sleep when the Wattman settings are not yet active and the system often crashes during that time - after which Wattman won't try to load custom settings again and I have to load the profile by hand.
Ideas?
