Radeon 5750 - Stuck in Low Level (idle) mode!!
I've searched high and low through forums for the solution to this. Unfortunately I haven't find a situation like mine. This 5750 card has been mining for a couple weeks without issue on an old computer running XP. In the morning I noticed CGminer hash rate really low. Well after a reboot that computer had major booting issues. I eventually loaded Windows 7, got the PC running and this time CGminer gave an Error -4 GPU DISABLED. Well I noticed in Catalyst that the core speed was 155mhz and mem speed 300Mhz with voltage at .950 V. This is the official idle mode speeds for this card. When giving commands through CGminer & Catalyst the GPU failed to respond or change. Note that when running -n CGminer did show 0 GPU and the openCL plateform active. So I decided to make a Bamt usb drive. Loaded bamt up, shows GPU Detected. But when I open AMDOverdriveCtrl I see that the GPU is in "Low Level" / Idle mode. Upon attempting to Overdrive to Mid or High Level the GPU does not change.
So to recap, it worked, then it stopped working on WIN 7 & BamT using latest drivers.
Any Ideas? Seems this card is in a lock down mode.. possible?
