I don't have any of the Overdrive settings out of the defaults. At idle my GPU Core Clock is at 500Mhz and my Memory Clock is at 1500Mhz.
Under load (3D graphics / Gaming) the GPU Core rises to 1050Mhz, upon returning to idle the GPU Core drops back down to 500.
However the Memory Clock remains constantly at 1500MHz. I'm pretty sure the memory clock used to have a slower idle speed as well. Am I mistaken?
