What does your 6800 Ultra overclock to?

I run at 450/1200 without any trouble. It seems to be willing to let me go much higher but I start seeing artifacts and slowdowns above that (heat problems maybe?). I'm using the stock cooler with some Arctic Silver 5 on the core.
 
440 max on core

highest mem ive tried is 1250 without problems.

man ive tried lots of bios on my card. used leadtek, bfg, gainward, thugs

one of my favorites is the latest nvidia reference one for 6800 Ultra.

currently at 425/1200 for everyday.
 
I only have a 350watt Antec True Blue, but I can still run 425/1200 no problem, and will go a little higher but not much. I keep it at 400/1100 usually because it is plenty fast, and I do notice my PSU rails fluctuate when clocked higher.

I did clock the ram once @1300MHz and left the core @400, then ran 3DMark2001. Made it thru every test but started to get major artifacts on the last test (horse). Using a 1.4v Thugs Ultra bios on an eVGA 6800 Limited Edition.

My card is a reference card so I think I have that BIOS...never checked it though.

EDIT: It's the reference BIOS revision 1. Has anyone tried the later revisions? Is there any difference?
 
460/1210 no artifacts in 3dmark 2005
or
480/1220 with artifacts but ok in games

Temps never go above 52c in room temp of 21-23C no mods to bios or vards as of yet

BFG aint overlocked just false claims as many out the box are 425mhz on the core as Nvidia said a Ultra must have at least 400 core and 1000 memory to be classed as Ultra, so thet would mean we could all say we got o/c cards as ram is 1100 on all ive seen even though ram is 1.6ns and does 600/1200ddr.

My card is not overclocked by default and its 425/1100 out the box. 🙂

EDIT, any u get good gains just replacing default gunk with artic silver 5 and did you use this on ram or ceramic as of risk of shorting out legs ?
