I am still testing why VID3 is not working, that is why i asked for a fresh factory bios from someone that hasnt flashed his card yet.
So far i have seen that VIDs 4-6 work fine for the 1V config, but i like to use the Vid4 just incase, becuse its closer to VID3 lol, vid 2 gives a stange behaivor, setting the lowvoltage vid to 5, when it should go down to 2. So far until i get fresh bioses from someone (GTX and GS) i am not going to update the ISO or come with a final answer. I have been testing timmings and geometric delta clock too, but i havent seen any real peformance gain on it for my card.
If people are concerned about battery life, i advice to use VID4 for now, and use the old nvidia control panel, under power mizer use for battery config use "maximum power saving", that way your card will ignore the thortle setting and go straight foward to 2d, that maximices battery life.
VID 03 = 1v on all the go79x0's
VID 07 = 1v on the go7900 GS and 1.24v on the both GTX's
VID 04 = 1.32v on the go7950 GTX only used here.
So is our GTX BIOS modded GS running on 1v or 1.24v when were on VID 07 ?
The voltage must be controllable as NVIDIA do it.
The go7900GS and go7900GTX have very similar BIOS's and board numbers, we can almost assume the same cards except for the GPU and memory amount.
The BIOS controls that if there is a go7900GTX use 1.24v and a GS only gets 1v on VID 07 (3D mode) 2 different voltages for the same GPU.
Now the go7950 GTX comes in with a very different board number and BIOS number and BIOS size.
The go7950 GTX BIOS has 3 VIDs it has VID 04 for 1.32v.
Does the BIOS switch to all 3 VIDs in certain performance modes ?
It's a pity there is no app that measures the actual GPU voltage, the GPU being stuck on VID 07 means very little, as it could still be switching internally.
One way is to clock the 3D clocks the same as 2D and see if there is a temp rise.
All in all very confusing.
If your new to this assume your going to loose battery life with the BIOS mods.
The BIOS mods are afterall to increase over gaming speed.
If you need more battery life just lower the 2D clocks accordingly.
Lots more testing is required to see what really happens.
