X1800XL:
http://www.xtremesystems.org/forums/sho ... ost1075680Well, it did and alot more better than that! Radeon X1800 XL running with XT's default voltage I got the GPU running at 705 MHz. Unfortunately I don't know yet how to raise the memory voltage so I just overclocked memory with default voltage (1,88 V). Memory ran fine at 705 MHz (1410 MHz) without artifacts. FX-57 running default gave me 9175 in 3DMark05.
http://www.xtremesystems.org/forums/sho ... ge=1&pp=25I'm stuck at 575 core / 550 mem until a tool is released to go further. This card is one HOT mutha. It ran in the 80'sc (90's in 3d) with stock cooling and is not locked in at 63c with a waterblock.

http://www.driverheaven.net/reviews/r52 ... ocking.htmRunning through a few loops of 3dmark and Doom3 showed no issues at these speeds so off we went again and tried 700/1700. This time though we ended up with VPU recover kicking in. After some playing around with smaller increments we found the card was completely stable at 685/1700
