Hello folks
So I also have problems with my 7900xtx Nitro.
I use: 5600x / x570 i Gaming/ 32 gb Trident z Neo 3600 mhz/ Windows 11. 850w Sfx Cooler Master & Be quiet 1200w Dark Power Pro. 2 PCI cables 1x daisy chain.
Windows keeps freezing on me. Even in the bios or during the windows installation.
With my Gtx 1080ti my system ran and still runs without any problems. However, as soon as I install the Sapphire, Windows hangs after a few minutes.
If I'm lucky and install Adrenaline, after restarting or freezing Windows, "Microsoft Basic Display" comes back and then another crash. Actually, I can't do anything without Windows hanging.
Strange things I've noticed: On desktop, the Sapphire jumps from 5% to 99% GPU usage and back again. The clock goes to 3100 MHZ in the desktop and back again. The temperature stays at just over 40 degrees. Graphics card information is not displayed in the bios. Bios shows
AMD graphics card only. The only thing I haven't tried is connecting the graphics card directly to the motherboard. I use a PCI 4 riser cable. This works fine with the 1080ti.
I also had a constant black image with image errors during the Adrenalin installation, which is why I think the GPU is not OK, what do you think?
I also have tried different Ports and DP/Hdmi Cables. Latest Bios (not Beta) and Windows Updates (new installation on a new M.2)
In terms of one cable per 8 pin connector, I can only shake my head. It can't be that I need 3 cables for a be quiet Platinum PSU with 1200 watt (all daisy chains) and then there are 3 more 8-pin connections hanging around( 6x 8-Pins total) ...
