100% no issues with idle 2D clocks here, 300/150, applied overclock and shot up to 1325/1800, finished bench back to 300/150, removed OC still at 300/150.
Just hit a 2471 in Heaven, another 20mhz on the core and another 100mhz on the memory should see me into 2500 territory![]()
Hmmm, now what could be causing this then pgi.
Are you using windows aero? Acceleration disabled? Windows basic colour?
