Geforce 6800NU overclocking
 
While I was fiddling around with my Geforce 6800, I noticed some strange overclocking results. Check this out:

60.80 Drivers
325/700: 7800 3DMarks
325/775: 8000 3DMarks
350/775: 8400 3DMarks (highest overclock)

61.72 Drivers
325/700: 8000 3DMarks
325/850: 8100 3DMarks
350/850: 8100 3DMarks
400/850: 9400 3DMarks (highest overclock)

Using the new drivers (which allowed me to clock much higher), nothing really happened with overclocking until - BAM! - I hit the magic 400/850 clock speed! 9400!. I never expected my 6800NU to run that fast. This sure seems to be the "sweet spot" for 6800NU OC'ers. I'm amazed what this card can do. Has anyone else gotten better results?

my best so far is 10034 with my 6800nu. I can clock it at 400/900. This is with the 61.34's. With the 61.72 I only get 9600. With the 62.11 I get 9900.

Jas28: Impressive. Maybe I'll give those 61.34 drivers a spin. What clock could you hit using 61.72s? Was it lower than 400/900? Do you think I could hit 400/900 if I changed my drivers? I'd really love to break 10K.

ChrisRay: I am running a Barton 2800 with 512mb DDR333 RAM, a Geforce 6800NU (of course), and an Audigy 2 ZS. I would clock it at 3200+, but I got duped into buying a KT400 (333mhz FSB) motherboard). I think you'd see some gains if you upped your core and put all that memory bandwidth to good use ...

Another thing, I'm very impressed with how cool this card is. I played Far Cry for 45 miinutes while overclocked last night, alt-tabbed with the temperature reading in front of me, and it was only 59 degrees!

Garik: Nice score. It's probably higher than mine was at stock because you have a way faster CPU, but I'll make a point of trying those drivers out.

hello!
here is my score!
i tested it with my xp2400 and OC 6800nu @ 396/824
3dmark2003

does anyone activate the other 4 Pipelines @ 6800nu??

Re: Geforce 6800NU overclocking
 
Carnivore: I don't think that's possible. Nvidia made a point of not pulling a "Radeon 9500", and made the 6800NU a different core than the other 6800s. I don't think the pipelines are physically there.

Thats really impressed sometimes makes me wonder whats wrong with my system. Either or Memory OCS dont seem to help 2003 much.

Chris: Try upping the core. Memory OCs really didn't do anything for me until the core hit 400 (as you can see). Will your drivers let you bring the core to 400?

Ya if I bump it up to 350/900 I get 9,250 3dmarks, I just dont have the urge to OC my core atm..

Maybe when games start actually running slow at the settings I play in.. I will. Until then its just benching goodness ;) However I see a huge improvement in Anti Aliasing performance with my Memory @ 900 verses 700. Which is something I see in every game I play :)
