I'm surprised that your cards have so many clock levels. Mine runs either full speed or 500MHz in games.


That's what i was telling him, GPUs don't have C states, they have their own version of speedstep however, the 1250 is my "boost" clock since i've modded the driver to go to that level, My old 460s had about 5 differant clock frequencies

Do the different clock levels each have different voltages on your cards?

there is 300/150mhz @0.85V idle and
925/1375 @1.17V load

i cant create a profile under 460/685 and thats what i was trying to do create a constant 300/150 @ 0.85V of when its idle

It seemed like the right solution to me - but apparently it's not. I think what the OP is looking for here is a best of both worlds solution that simply isn't available in this configuration.

I'd say if you are looking for gaming performance at a level above that of the IGP - but you want a voltage draw that is significantly less than what your current discrete GPU can provide - you need to find a GPU that is just BARELY enough for the most demanding load - and then enjoy the benefits of it's lower power envelope when it's not in use.

In any case, good luck.
