Weird Gigabyte 7950 issue (possible mobo issue)

post #1 of 8
Thread Starter 
Hi everyone, I picked up a Gigabyte 7950 earlier today for a sweet price used. Before selling, the seller showed me the graphics card working in his computer. He then packaged the card up and gave it to me, and I safely transported it home. When I got home, I couldn't get my machine to POST with it in. Here are the configurations I used, as I was going to use this card along with my ASUS 7850 2 GB for crypto currency mining.
1: 7850 in slot 1, 7950 in slot 2, both connected via PCI-E power
2. 7950 in slot 1, 7850 in slot 2, both connected via PCI-E power
3. 7950 in slot 2, connected to PCI-E power
4. 7950 in slot 1, connected to PCI-E power
5. 7950 in slot 1, connected via PCI-E & molex adapter (8 pin connected by molex, 6 by PCi-E

then I tried using 7850 in the slot one with no other cards and it booted fine. I then proceeded to try using the 7950 in my main rig, number cruncher. It booted fine, so I'm wondering what you guys think is wrong. I have a feeling it's the motherboard, maybe I need to flash the bios with the newest one, but I just want to know what you guys think might be the problem first. Both systems have a 750W power supply.

Yeah all fans soon but no beeps. I've also tried a different PSU as well in the system with no go, although this PSU powered the card in my test rig fine last night, which leads me to believe its a bios issue on the board. I'm going to try flashing the latest bios to it in a bit.

I would leave the 7850 out of the equation and just concentrate on the 7950. Try with no cards installed a CMOS reset then install the 7950 and see what happens. Good luck.

Well I flashed and updated the bios and now the card seems to work as a display, but it doesn't give me the temps or clocks or anything in any program, so I'm updating my drivers now and see if that works.

Sounds weird, but try running the monitoring program as admin. I had that issue, not sure what causes it.
