Overclocked 6800GT: not much performance increase

[crsgardner]

On the recommendation of others, I overclocked my 6800GT to Ultra levels (400/1100). It runs stable, but I'm getting nowhere near the 13000 3DMark2003 score others have mentioned. Here's a comparison between stock and and overclocked. Am I doing someething wrong?

10825 3DMarks?

That is odd... I get over 11000 with my GT at stock speeds with a P4 3.4C. Your cpu is listed as "AMD Athlon(tm) 64 2003 MHz", which A64 do you actually have?

Possibly your card is throttling down because it can't handle the ultra speeds. Mine did the same thing and I found that 400/1080 is the best it will do and will give me 12080 in 3dmark03 as opposed to 11280 stock. At Ultra speeds (if it doesn't freeze) I'll get a score similar to yours.
Not all gt's can hit ultra speeds.

First off you are using some OLD drivers... Get atleast 61.77's There are some newer beta 65.22's which are even faster. If you look in my sig I don't even get 13K I get 12945 with this set up with the 61.77's so don't expect 13000 unless you have a smoking fast system.

Also if you get freeezing. turn off Fast writes in the BIOS.

Old drivers, and cpu limited. (cpu doesnt really effect 3dm2k3 like it should though)

I got my best 3DMark score by using the 62.20 drivers. I switched to the 61.77s and they are pretty close to the performance of the 62.20s.

Well...by taking my 6800GT to 6800Ultra levels I got 2,000 more 3dMarks...so I'd say overclocking does do something.

I get 10768 with a p4 @ 3.08 with a Leadtek 6800gt
