if you have stock cooling and no ram sinks then do not over clock it to the max as it will shorten the life of your card.

For coolbits, put 'coolbits' into google. You'll find like 100 sites to download the registry patch to add in the tab for clock speeds. The .reg file is TINY.

As far as the speeds to shoot for, go up slowly to FIND your max. You can't know the max before you get the card. My 5900XT actually overclocked very poorly for the memory, I'd get texture artifacts with only a 20 MHz overclock. The core overclocks okay, but not great.

I ordered a refurb 5900xt and it shows up as a 5950U core is 475 and mem 950. has 128M ram guess it was flashed? has no artifacts no ram sinks seems to work fine. benches 5459 in 3dmark2003 on my 1833 tbred so it seems like its performing as a 5950u? wonder why it was sent back?

No, you can't.

You're terribly naive if you think every card will perform exactly the same as the one they reviewed. Each individual GPU chip is different.

Here are three different reviews for my card and they all reach different stable overclock speeds:

http://techreport.com/reviews/2003q4/geforcefx-5900xt/index.x?pg=13
http://www.hothardware.com/viewarticle.cfm?page=7&articleid=385&cid=2

My card won't even run 750 MHz on the RAM, and all these reviews show 800+

You're totally fooling yourself if you think you'll end up at EXACTLY the numbers in that review just because you bought the same TYPE of card that was in the review. Even the same exact card in different conditions may not reach the same overclock because of cooling, power supply or other factors.

Start small and work your way up to where it is stable. It's the ONLY way to find stable speeds for an individual card.
