I've noticed that with the boost table, and the block values on that table, certain slots with clock speeds require a certain voltage, on the voltage tab to run that specific clock speed. However if you change the boost table so that the very first yellow slot, is your desired clock speed (for me that's the 21st slot), The desired clock speed will stick, with whatever voltage you choose to run. The downside with this is that if you do for whatever reason briefly go above the TDP or 83c+ temperature benchmarking, You will throttle down to 862 (the 2nd green block value).
This is why i have found my happy medium to be the 39th slot. Because if for whatever slight chance or reason i do happen to briefly throttle, i won't instantly drop down to 862. I'll only drop -13Mhz below the 39th slot value, (doing it this way also allows me to have different voltages on my cards, if i ran both on the stock boost table, it would require both my cards to run at 1.212v for a 1200+ core clock to register) which in my case right now would be 1189 because i found that 1215 wasn't my stable OC and 1202 was.
This also lets people that want to experiment with higher memory oc's vs core ocs downclock their cards into the 1100 range on the core. With the boost table on a stock bios, the slider is all the way to the left at a generic 1202MHz in the last green box. If you increase that slider to the right all the numbers in the yellow box change. Allowing you to lower the core clock on the first page of the KBT, with the boost limit boost max and base clock speeds.
Also what is an EFI bios? The bios i'm running is the the most recent one off the EVGA forums for the GTX 670. Flashed to both cards, and then i dumped the .rom file using GPUZ, and modded it from there, reflashing with nvflash for windows.
I really want to venture into a higher range on my cards. But my temps hold me back a lot. If temp contributes to a high TDP value. Then i am stuck with what i have until then. My highest score on 3Dmark11 on air is this. I wanted to break 20k gpu score (about 500ish less than SLI GTX 680's)
