Ram voltage isn't too much of a big deal as I watched the VRM current in comparing 1.5 and 1.6v at 1700. At 1.5, 2 amps x 12v= 24watts. At 1.6 2.3 amps x 12v = 27.6 watts. 3.6 watts is not much of a big deal especially because the ram is cooled by heatsink.
Yeah I tried running rbe on a 6xxx and 5xxx bios modding the fan table, the version where you set speeds for temps and the differences weren't findable in the 79xx bios.
In fact, I find it dumb that they went to that way of fan control. My old nvidia gtx260 had a smarter way, it would spin up to keep the temp below a threshold, not this crap set table of temp/speed (which you can see in MSI AB).
For same load:
In summer you may need 65% fan to keep it at 70C,
But winter, you may only need 50% fan to keep it at 70C.
With these cards, they will just do what the table says. So let's say it is 65% for 70C. In winter, it will end up running like 55% and get it to 65C. So it's not a true temperature control, just a crude one, like we have for our motherboard cpu PWM header.
With my old 260, it would use what speed it needs to get to whatever temp is requested. Nbitor bios editor even allowed me to change those values!
