The reading or where you set the clocks? I tried getting the VID related to more voltages but I got a yellow dot with a warning. Just wondering you mean that your clocks are not going up with 1MHz steps? Well just to outline that is just normal and is like that for all GeForce 8 series. Nothing you can do about it, that is just how it work for the clock speeds and is similar to the ATI cards as well. Yes, adding more VID's then the 4 currently available is stroking with the BIOS structure of the GeForce 8800 series.

I'm keen to achieve a stable long term overclock on this card. I can upload the original BIOS too, but not until next week when I return. Any help or advice would be appreciated. Thanks again. Well that can happen, and we also saw that with the SCC version of EVGA that could overclock easily with the default BIOS to 770MHz and with the updated 1.1V BIOS it wouldn't. Now the only thing we could think of is the heat levels that need to be checked and also that NVIDIA lowered the max temps before the over voltage and over heating protection kicks in and that means lower performance. And with at extra 0.05V you might be just hitting that limit.

Re:Who is owning a GeForce 8800 GT, and ready for tweaking? - 2007/11/13 17:21Do you think that there is any chance to increase core voltage above 1.1V, since with BIOS update it increases the core voltage from 1.05V to 1.1V. But is there any chance to go further, like 1.15V? With current NiBiTor it seems impossible, but at next version could it happen?

I am gona ask it once again, by when are you going to really understand that it is not NiBiTor controlling the possible voltages but the BIOS and the graphics card? It is completely possible to do what you want and it will just not make any difference. Again, first try to understand the logic and then you will see that NiBiTor is not to blame nor will an updated version solve anything what you want as it is not under NiBiTor's control...

Then how could it happen? Cause I could get up from 1.05V to 1.10V and it worked? Can you explain cause I don't get it really.

Re:Who is owning a GeForce 8800 GT, and ready for tweaking? - 2007/11/14 03:22Thanks for the reply, and for giving us this great resource... Still trying to figure this out, with running AquaMark 3 and checking the benchmarks figures on different speeds, seems that 731MHz works better than 740MHz. Watch this space.

Re:Who is owning a GeForce 8800 GT, and ready for tweaking? - 2007/11/14 03:50So, we've discovered it was the timings on the ram that had been loosened. I believe it had been done by yourself Mavke, to be on the safe side when overclocking. So, my friend has put the timings back to stock, and raised the GPU's volts to 1.1V, and is reflashing. Fingers crossed!

Okay, but I am not really that confident in AquaMark 3 results, cause with my GeForce 8800 GTS and Ultra when I run it several times I see a difference of about 200-300 points, and never the same results really. In fact AquaMark 3 is depending too much on the CPU of the computer, so you really need to start looking at a better benchmark that give the same result at each attempt, something like 3DMark06.

Re:Who is owning a GeForce 8800 GT, and ready for tweaking? - 2007/11/14 10:56We were using 3DMark03-06, but for some reason ORB won't let us submit marks, and the programs don't display a score at the end anymore. At least, not the current versions we've been downloading. We got slightly better results with the original timings and the 1.1V modification. But these diminished when the memory was pushed above 2030MHz. I'm wondering if some more tweaking of the memory might solve the problem. It's almost as if we're creating a bottleneck within the processess that exist between the memory and the GPU. Hmm, the quest goes on...

Re:Who is owning a GeForce 8800 GT, and ready for tweaking? - 2007/11/14 19:22Well there is always a trade off that should be made between the GPU and the memory when overclocking. Cause at a certain point a higher memory overclock will always have a negative impact on the stability towards the GPU. More tweaking would be to relax the memory timings... But at 2030MHz you can't really complain much.
