Hi guys, iv just got an asus dual fan 4890 and when i overclock the memory even 15mhz the screen flickers or blinks in situations like scrolling page when using internet or switching between windows etc, iv tried drivers without ccc and also windows 7 and currently using vista x64 but still get the issues, the only time it doesnt happen is when i put the cards memory clock back to stock mhz,
whats also weird as i can go 1000mhz on core and when i game with mem oc the flickering doesnt happen except loading between maps or viewing score sheet etc,
at 1000/975 i get 20k plus in 3dmark06 and it games amazing so dont nthink its a duff card either.
the best way to describe it is a blink for .5 of a second like im using freeze frame or something and happens 2-3 times a minute
any help please guys??
