Hey I was wondering if anyone could help me. I only got this new sapphire HD 7970, vapor-x ghz edition yesterday and tried to install it today, I haven't overclocked it at all. I updated it with the latest drivers and initially I was wowed by its performance in Crysis 2, max settings and great fps. However, after 4 or 5 minutes the screen went red and there was a stuttering sound then the system rebooted. I tried it with deus ex HR and that did the same. Planetside 2 ran at an average of 59 fps but after 10 minutes dropped right down to 10fps or lower after an initial stutter. I can't find a fix anywhere, it seems a lot of these red screens are happening with Nvidea crads but not so much AMD.
Another thing I noticed was that occasionally small white lines would flicker across the screen when idle at the desktop. I initially thought it was the hdmi cable being loose but I'm not so sure.
I was running the same system with a 6870 before and it was all smooth, no problems. So I'm wondering what to do, I'm not sure how amazon handle GPU returns and have heard sapphire have terrible RMA times in the UK, up to 30 days so if I can I'd like to try to sort it out
Here's my system:
GPU: sapphire amd hd 7970 vapor-x ghz edition(stock)
CPU: I5 3570K at 3.4ghz(stock)
Ram: 8gb kingston hyper x 1866
HDD: 2x 1tb seagate 7200rpm
PSU: 650w Antec Truepower
Mobo: Msi z77a-g43
Case: Zalman z-11 plus
OS: Win8 pro 64bit
I tried the beta drivers with crysis 2 but it still crashed after about 5 minutes, although this time it only ctd'd not red screen and reboot.
I have noticed that there were 2 8pin-double 4pin molex connectors for the power but I hadn't plugged both molex for each 8 pin connector. Wondered if I was doing something wrong here? (connected both now).
Still crashes but not with reboot so far, notice the card makes a high pitch whiny noise whilst playing games (not loud though). Reckon the plugs are configured correctly, both molex pins are attached to a branch of connectors that go to a 6pin-psu.
Ok after all this fretting, I realised that I had left a residual clock on my cpu to 4ghz but didn't think it had set, so it seemed to have caused all this. Reset it to stock and have been playing games for the past couple of hours without crashing.
