EDIT: Here is what I meant to be the original post: I have two 4570x2's in the rig, but the second GPU cannot exceed 66 degrees Celsius or the OS will crash (I assume the GPU goes into shutdown).. this is most likely due to bitcoin mining years ago OR a power supply issue. I'm not exactly sure why it's always at the same temperature that it shuts down.
I would like to limit my second GPU to about 50% or perhaps both cards to 65%, whichever keeps the temperature in the green. I've tried to limit both cards by decreasing core clock speed (via MSI Afterburner) but that seemed to crash the PC almost instantly when the GPU was activated via Borderlands 2 launch.
I haven't got much money, so water cooling or a 1k watt PS isn't really a viable option. I can run the primary GPU fine with no issues.
Thanks for any assistance.
Old post: Second Crossfired HD Radeon 4870x2 Crashes exactly at 66-68 degree Celsius. First GPU operates very well. Second GPU has mined bitcoins for a long time. PSU is a possible option, but I consider it unlikely. 650W with ~50-55A on the +12v rail.
