I run mine 1528mhz 24/7 (many people hitting 1550, some even 1600), but on the lowest power limit i can set stock bios (100w) mine still averages over 865mhz.

What do you get on Unigine heaven 4.0 extreme preset? I have ~53fps on minimum power limit (100w) and 84.9fps on 24/7 stable clocks using the benchmark run.
Kepler was really damn efficient when you ran it at ~55-60% of potential 24/7 clock speeds too tongue.gif these things are just a good 60 maybe 70 percent better in an apples to apples test.

Whoops lol! I dunno where I read 865Mhz from, it was actually running 1125Mhz.

Getting 63.5 FPS on stock clocks, can get about 67.5 with an overclock on the core/mem (~1175Mhz / 3800Mhz). Gonna do some more tweaking to see what I can get

Perhaps there might be more tweaking to do to get better performance at the same power limit?

Unfortunately there is very little. Nvidia has given us only low amounts of control of their cards since Kepler release, they still perform awesome though.1175 is a tiny overclock; ~1550@1.25v isn't uncommon, but that's more in the 200w range.

Maybe voltages are controllable with custom bios - clock speeds should be, too.
