I have a couple 5970's that keep crashing my systems. I am able to get one core rocking at 350 MH/s....but as soon as I start up the second core, everything freezes, the driver crashes, and sometimes there is a BSOD.
Anyone have a potential solution?
Win7 64-bit, 750W PSU, Sempron
Don't over clock the second core.
Also, your core voltages should be 1.05v.
I have some OEM 5970s that are like this. It's is infinitely better to at least have them running then to overclock too much just to have them crash all the time.
