Hey guys, there's a long version of this story over on overclock.net forum ..
http://www.overclock.net/t/1481409/have-i-been-sold-a-dud-card-7970-crossfire-issuesHere's the basics.
1. I bought 2 cards to upgrade from my trusty 6950
2. Had random hang ups in games and sedentary duties like watching videos.
3. Tested cards individually. One of them was overheating. I stripped it and replaced the TIM. Twice. Didn't entirely fix that card's issues but the other one's temps were fine so I put that card in on its own to get by for now.
4. System still hanging up on the good card.
5. After multiple driver versions I put the 6950 back in and the hang ups persisted. Even started doing it in BIOS.
6. Switched in a spare 500W PSU. System worked perfect until the first round of Windows updates and a restart, then hung up immediately so I gave up for tonight because it's pretty much pissing me off and I'm about to put it in the bin. I'll come back tomorrow with another PSU and hope for the best.
Right now it won't even boot to Windows reliably, just hangs up all over the place. Multiple graphics cards, multiple PSUs, same result. Thinking CPU / motherboard, likely motherboard based on past issues I have seen in other systems.
What's the warranty like on these things, does it carry over from owner to owner? I bought this board 2nd hand and have had no issues with it for a year up until now
😞 I don't have any paperwork for it. I'm not thrilled by the idea of buying a new board just at the moment so figured it can't hurt to ask.
Cheers,
Sam
