When saving OC settings it seems to bump up the 'standard 2D' mem clocks to whatever I've set them in 'performance 3D'... Is this normal? I'm guessing it's able to core throttle when switching from 2D to 3D but the mem clocks just stay the same 24/7... Unless I'm doing something wrong here.
Not very familiar with RT or even the Detonator OC options, been a while since I've had a card that was really worth OC'ing.
I did manage to unlock the pipes on this 6800 just fine and I've been stress testing with rthdribl, seems to have taken (temps haven't gone up past 65C with the NV5 either). I'll fire up HL2 later for some real testing...
