Finally got around to maxing out my 5900 Ultra as it looks like I'm going to need to do this with Halflife 2 just to get playable framerates. After doing some loop tests in 3dmark and playing the games I play this is what i've OC'd to:

540 Core
945 Mem

I can go to 548/949 without getting artifacts, but I clocked down a little for stability and I like more rounded numbers.

Is this pretty typical for a Gainward 5900 Ultra Golden Sample? I thought I might be able to get a little more out of the memory... Hopefully this will give me the power I need along with the 52.xx's to play H2 at exceptible frame rates. ;-)

Autodetect usually would recommend the following:

490 core
885 mem

This would fluctuate by 10 or sometimes 20 for each frequencey.

I have a Leadtek WinFast 5900 Ultra 256MB card with Det45.23 & I'm assuming u're using Coolbits to run the OC test. My OC sliders can only go max until 850 MHz for memory, so I'm wondering if ur 900+ settings were from Auto Detect or is there an updated Coolbits registry setting that enables >850 MHz clocks. Thanx.
