Hi guys,
Just got my 6950 cards, hooked them up but when I'm in crossfire mode the two games I've tried so far, Deus Ex HR and BF3, will reboot the system after about 1 or 2 min of game play.
This is my setup:
CPU: i5 750 @ 2.66 (NOT oclocked at the moment)
Cooler: Noctua NH-D14
Memory: 4GB
PSU: OCZGXS700(700W) - http://www.newegg.com/Product/Produc...82E16817341002
GPU: 2x Saphire Dirt 3 edition 6950 (stock spd and bios)
GPU Driver: 11.9
MOBO: ASUS P7P55D Deluxe
OS: Win Home Premium 7 64 Bit
What I've tried:
1. Disabled Crossfire (through Catalyst) which works fine, a single card has no problems.
2. Swapped the cards (moved card 1 to slot 2 and card 2 to slot 1), still works fine in NON crossfire mode, so at lest each card on its own is not causing any problems
3. Used GPUZ to check temps, nothing over 60ish Celsius.
I'm pretty much at a loss of what to do next, should I try the other Crossfire cable that came with my cards? I haven't done that yet.
Is 700W enough? I only have a single HD in the system, nothing else except for what I've listed above, oh well, I guess one standard DVD RW drive, nothing special.
Could I be connecting the wrong 6 pin connectors to the cards? I have like 6 of these things coming from the PSU, so I'm not sure if I'm doing something wrong there... Any help with that would be awesome!
Anyway, please let me know if you need more info from me, I'll be happy to provide.
Thanks!!
