Hi everyone,
So I recently rebuilt my system, here are it's current specs.
AMD Phenom II x4 965BE OC'd @ 3.8 Ghz with stock heatsink/fan.
Gigabyte GA-890FX-UD5 PCI Express 2.0 Dual x16 Single x4 Single x8 Slots Motherboard
G.Skill Ripjaw Series 2x2GB DDR3 @ 1600 Mhz 9-9-9-24-2T
Corsair CMPSU-750TX 750W with 60amps on +12v single rail
2x XFX ATi Radeon HD 5770's reference coolers @ Stock Speeds
Primary in top x16 slot
Secondary in third x4 slot
1440x900 @ 60 Hz VGA LCD Monitor (Planning on replacing with either 1920x1080 or 1920x1200 24" DVI LCD soon).
Windows 7 Professional x64
I've been running on a single 5770 for about a year, just recently bought the 2nd one. Had to enable crossfire in Catalyst along with Catalyst A.I. (previously disabled), version 10.10 now. I also installed some application profiles for ATi, one from the official site one from some hardware site. I spent 2 days unplugging the video cards, plugging them into different slots, and then running benchmarks on performance in Unigine's Heaven demo.
My problem is that now it seems like BFBC2 and MW2 crash randomly, anywhere from the main menu all the way to around 1 match, maybe <5 mins. taking my whole computer with it (I have to do a hard reboot). When I disable crossfire in Catalyst, I don't seem to experience the crashes, but it's hard to tell since it's random.
I have the bottom card in the x4 since they were on top of each other when both are x16, and the top card was pushing 80c under load. Idle for top card now is around 47c. Ambient temp inside case and CPU are both around the low 40c. As far as I can tell, I get the same framerate in Unigine's Heaven as published specs, whether it's dual x16 or 1 x16, 1 x4.
Is anyone else experiencing crashes like this with 5770's crossfired? Is it because of my settings? Did I unplug/insert the cards too many times and somehow damage them? Thanks in advance if any of you can help me with this.
EDIT: Forgot to add my PSU, added at the top and here: Corsair CMPSU-750TX 750W with 60amps on +12v single rail.
