Hi all,

I've been dabbling with OC'ing my GTX260 a little but have noticed a discrepancy between clocks shown by Furmark and Afterburner.

Furmark when running shows my GPU speed to be 650Mhz, as I set it in Afterburner, but after exiting Furmark and checking the Afterburner graphs it shows GPU was never over 400.

I provided a screenie of the issue with Furmark running windowed to show the issue:

Has anyone encountered something like this before and can tell me which reading is correct or how to resolve this?
