Hi guys I just picked up a 5970 from eBay for $80 the guy I bought it from believes it works fine (although he was quite eger to get rid of it selling it for 80 bucks). So I get it and set it up and run gpuz because i've herd of 5970 not showing a second GPU and loandbehold crossfires disabled so after about 4 hours of forum surfing I tried running atiflash just to get a read and see if the problem is windows related and it turns out that atiflash doesn't pick up the second (or possibly master) core so I've narrowed it down to being a bios/hardware issue and not windows or software I'm thinking the best way to solve this would be to try the 1+8 pin trick see if that's the problem but before I do that I'd like to get another opinion on the matter thanks in advance
Its was a 2 day auction so I could have got lucky but I do agree these obviously something wrong with it so my question is without RMAing or sending it back to the guy I bought it from can I fix it at the moment the single gpu works great I've been playing games on it just fine I even did a fur mark to see if it was stable and its fine. I also flashed a newer bios to the one core that dose show in atiflash and that works fine. I just cant understand how the second Gpu completely disappeared there should be some trace of it somewhere shouldn't there
Are you using a USB 2.0 flash drive? If so, make sure it is in a USB 2.0 slot...I know it sounds silly, but I had the same problem when I tried to reflash the bios on my cards. Once I booted from the USB using a 2.0 slot, everything worked fine.
Also, since your other card works fine, make sure it is completely removed prior to flashing the bios.
Now this part I'm not sure about...I don't really have much of a clue on how multi-gpu based cards work, but does it have an individual bios for each gpu on the card? If it does (again I must stress that I don't know), try using this command to flash both gpus...
