I started OC'ing my HD3850 this morning. Would've ordinarily done my CPU or something but this IL9 pro seems to detest overclocking in every shape and form, only thing i can tweak is the memory speed, and even then i only get to choose 533 or 677 mhz

Anyways.
All done using catalyst, Cooled using stock gfx cooler, 2x rear exhaust fans, 1x gpu exhaust (on the side) and 1x intake on the front.
7840 - HD3850 @ Stock (669/829)
7847 - HD3850 @ 669/859
7852 - HD3850 @ 680/889
then i got really bored of doing the little step thing, so i just turned on the TV and set the auto tune thing going lol
8039 - HD3850 @ 759/1019
I remember coming back 10 minutes later and going "
WTF?!?!?!" at the memory clock

Not too bad i don't think, all 3DMark tests done with no AA at 1280x1024 with specs described in my profile.
