Geforce 6800NU overclocking

[ChrisRay]

I think so nvjarret, A lot of people seem to be hard on the 6800 because its not "killing" the 9800XT and 5950 in all situations with AA/AF. Thats mostly because of its memory though.

The card has proven to be very stable for me. And I have enjoyed it a great deal. But I reccomend OCing the memory as much as possible. It will help with AA/AF where the card seems to have a lil trouble at higher resolutions.

The 6800NU pretty much "kills" the 5950 and 9800XT up to 12X10 4X8X at most benches I've seen. It's about the same at 16X12 4X8X. I'd call that a "win/win".

I really like the 6800NU nVJarrett and can't imagine that it couldn't run Doom3 at 10X7 OX0X. If it can't, there will be a HUGE outcry in the gaming world because that would mean 99% of the people who buy it would be royally screwed.

NVJarett: I'm a big fan of my 6800NU too. If you have an Athlon XP system, it's the best choice, I think, because bottlenecking would prevent the more expensive cards from being worthwhile. It does a great job of handling all the games I have - including Battlefield Vietnam, UT2004 and Far Cry - and can hit x800 3DMark scores with modest overclocks, depending on what kind of system you are running.

The 6800NU is an excellent card for the money, and since Doom 3 is OpenGL, and nVidia cards tend to do well on OpenGL, I don't see how you could go wrong.

cool thanks; that leadtek looks pretty hot

I know this thread has been dead for awhile but I want to use it to *cough* consolidate similar recent threads, and ask another overclocking-related question.

When you overclock a CPU, for example a Barton 2500, you get best results when the CPU clock speed (before being multiplied by the multiplier) is synchronized with the RAM clock speed. If you used DDR400 RAM, it would be best to have a clock speed of 200mhz.
Do graphics cards have multipliers? Would I get best performance if I found a clock speed that synchronized RAM and CPU clocks? Is this why I got inconsistent OCing results, with little speed increase except under certain "magic" clock speeds?

If so, what is the Geforce's multiplier? Does it have one? Are the clocks synchronized at 350/700, 400/800 and 425/850, or does the multiplier make things more complicated?

If anyone can enlighten me on this, I would appreciate it. I'm going to do some benchmarking when I get back home from vacation to see if 1:2 clocks are the most advantageous, but until then, does anyone else know?

Ok we all know you just made that **** up,why even bother posting?
6800nu's have 16 pipelines,but 4 of them have not passsed testing ,they can SOMETIMES be re-enabled without artifacting(mine for example)There is a pixel shader to be activated as well...bringing them to 16/6.With an arctic nv5 I can reach 425/900 on my card with no artifacting

Yep I can hit 425/900 to at 16/6 with my NU too.
Over 13k in 3d03 easy. with the XG81.95v2 driver.

which company is your 6800 and what is your system specification ?
