Wake from sleep issues -
| posts: 2
I've been using AfterBurner for quite some time now and have always had this problem, but could never find a solution. I have a Radeon HD 5970 OC'd with AfterBurner to 1.162/850/1102. Everything runs fine during normal operation and extended gaming use. However, if I put the computer to sleep or hibernate, after waking, if I try to launch a 3D application the graphics card freezes. Sometimes it recovers, and sometimes I get a BSoD as well. I've done a lot of searching and tried different things. One person suggested manually changing the ATI Control Center profile to increase the idle frequencies of the GPUs. Nothing has worked so far. However, after sleep, if I manually change to the default profile in AfterBurner, then switch back to the OC profile, the problem seems to be prevented.
I believe the problem may have to do with the voltage increase not being applied after wake. I think this because if I disable AfterBurner and apply the same OC settings in ATI OverDrive, I get the same freezing behaviour (and the voltage is the only thing that is, seemingly, different).
Does anyone have similar issues or know if the voltage is, in fact, the problem? If so, any solutions for this?
