Overclocking 8800 gts 640mb?

I'm sorta new at this stuff so please bear with me, thanks.
I just got atitool to overclock my 8800 gts 640mb from core 513 and memory 792 to core 600 and memory 1075 (for all columns)
I took the fps average from css stress test before and after I overclocked it, but they are almost exactly the same. Am I doing something wrong?
I change the numbers above the bars, I save, click load, and then I minimize atitool.
Am I doing this right?
Thank you

edit: and yes I have read the sticky, but I can't seem to download coolbits

edit2: i just oced my processor to 3.05 ghz and i'm still gettin 59.xx fps on css stress test no matter what I do. Is it because my monitor only supports 60 hertz?
thanks again

Why don't you bench with 3D Mark06. and see if you get some different results.

Here are some more 3D benchmarks that you can use also,

3DMark2001se
3DMark03
3DMark05

Just wondering,but why don't you use the Nvidia Ocing program that came with your card?

you mean ntune? people have been saying that programs is pretty bad.

anyway i think the reason why i kept getting 59 fps no matter what was because my monitor was limited to 60 hertz

Yes, I was talking about ntune. It has worked fine for me and has allowed me to OC my 8800GTS to 680/975.

As for the refresh rate that you are talking about.........

The only thing that comes to mind when you say that your FPS results are similar from stock to OC settings would be that you have Vertical Synchronization or Vsync enabled.

When VSync is enabled, what happens is that your graphics card is told to wait for your monitor to signal when it's ready for a new frame before supplying a single whole frame, each and every time. It can't race ahead, it can't just pump out lots of partially completed frames over old ones whenever it's ready - it has to provide a single whole frame to the monitor whenever the monitor says it's ready to refresh itself during VBI. The first noticeable impact is that your FPS becomes capped at a maximum equal to your current refresh rate. So if your refresh rate is 60Hz for example, your framerate can now only reach a maximum of 60FPS. By itself this isn't really a problem, since every monitor can do at least a 60Hz refresh rate at any resolution. If your system can produce 60FPS consistently in a game this should be more than enough FPS to provide smooth natural motion for virtually any type of game.

If you want to see higher FPS then you would disable it. Now it is not a bad thing to have Vsync disabled, your graphics card and monitor do not have to be in sync. but when VSync is disabled, you can experience a tearing in periods when your graphics card and monitor go out of sync because the graphics card and monitor are acting without regard for each other's limitations.

I would personally turn it off and see how much higher your FPS is. Also run some 3D benchmarks as you will get a better overall picture of your FPS from stock and OCed settings.


Hope this helps.
