Why Nvidia control panel for OCing ??

post #1 of 3
Thread Starter 
Hello, I am looking for results using the Nvidia Control panel to OC their GPUs , This came already installed on my gaming pc which has two EVGA 8800 GTS 512's on a EVGA 780I MOBO.

I am using 64 bit Vista I have tried installing both RIVA TUNER (adding the G92 line) and ATITOOL by disabling driver signing and they still do not work well enough to use.

As Nvidia control panel seems to be the only software that allows me to adjust the GPU clock as high as 815 MHz on these cards and run at 1166 mem clock, 1950 shader and you can also adjust the fan speed of both cards in sli right under the clock settings.

However I have run 3DMARK05 and 3DMARK06 several times by setting the GPU core on the Nvidia control pabel anywhere from 650 MHz (stock) to 810 MHz and all my bench marks are in the same ball park 3Dmark05 21000-23000 and 3Dmnark06 scores 17400 - 17700.

Further monitoring my GPUs temps while running the BMs using CPUID the idle temps are only about 40c when running the BM only go up to about 48 with fans at 100% if the fans are set to thelow stock setting of 26% then the loadtemp goes up 10c from 48 to 58 c so atleast withthese BM tests regardless whether I have GPU set at 700 Mhz or 800Mhz there is know appreciable increase in my BMs and no increase in temps indicating that its working harder (unless my side fans are helping also) either way my GPU temps seem to reasonably low from what ive seen reported on here so perhaps the duorb on order may not helpme much. but I am not sure what else I can do to get even more note worthy 3dmark BMs with out upgrading the CPU to QX9650 but Im not gonna drop another $1000 for that CPU to do it

So I am wondering if A the Nvidia control panel is really not working to actually increase the clock speeds or the GPUs have no useful OCing which i doubt or maybe C 3DMARK BMs are not rigorous to show big dffrences in results and temps. Please post your thoughts on this.

You can try this I have maxed out at 800/1050 for my GTS' SLI overclock. Are you sure you did the added line for riva tuner? Did you add this G92= 600h,610h-61Fh , then re-boot? I am thinking of doing my oc with a bios editor.

by the way I think the core clock is 670 not 640.

Yes I added that line and finaly got the RIVAtuner oCtab to come up but when I tried running BMs with it would crash sometimes getting the blue screen of death atthat point i just uninstalled it. For ATITOOL after i disabled the driver signing on booting the I could move the clock sliders but every time I would hit enter and would just default back to zero, so I am puzzled at what else to do.

I see the spec sheet on the EVGA 8800 gts 512 says 670 mhz however when you bring up the nvidia control panel the default says "factory shipped frequencys" which is 650 clock, 972 mem clock, and 1625 shader .
