    1050 wasn't stable, but wasn't that in p5? does it not use a lower voltage than p0 state. give the line a try, why not

    -setBaseClockOffset:0,0,165 is an invalid line but lowering it to 135 with the rest the same worked at 1000/2500MHz. The line is:
    -setBaseClockOffset:0,0,135 -setMemoryClockOffset:0,0,500 -setGpuClock:0,2,1000 -setMemoryClock:0,2,2500 -forcepstate:0,0

    Still, I kind of like clocking it to 970/2500MHz via P0 without having to force the pstate because it clocks down automatically if it’s not needed. As for voltage, I tried 3DMark at 1100/2500MHz in P0 state and it locked up at 80% loading of the first test, the same happened with 1100/2000MHz in P5 state. I’d be interested to know if anyone with my Dell and an i5 has the same problem, if it’s better with the i7 configuration (130W adapter) or if mine is just a “lame horse” xD.

    I didn’t plan on overclocking, personally I’d do it only with a beast like the Asus G55WV because it has way more cooling power than it needs. I tried playing Planetside 2 for a couple of hours and with 950/2500MHz I get a maximum of 74°C on the CPU and 72°C on the GPU which is 2°C and 5°C more than on the default clocks. For some people that’s low but I wouldn’t mind if it never went to 70°C because that’s around the temperature at which the fan goes from “don’t mind me” to “sup son”.

    There is a bios mod with unlocked OC abilities and advanced level BIOS menu

    Might want to check that out

    My settings are the following: 1090/2500.
    nvidiaInspector.exe -setBaseClockOffset:0,0,345 -setMemoryClockOffset:0,0,500 -setpowertarget:0,111 -setVoltageOffset:0,0,0 -setGpuClock:0,2,1090 -setMemoryClock:0,2,2500 -forcepstate:0,0
    I think it is stable, i played far cry3 more than 6hours. GPU temp: 57-60, core temp: 60-65 with turbo off. On the other hand Im using a coolermaster u2 cooler, which is the best for m14xr2 (in my opinion). I also tried to clock the core to 1150mhz, but it's not stable. After 1hours my m14 turned off suddenly. It's really interesting,because my computer used its battery, and almost full charged. After it turned off, i tried to turn on but i couldnt. The gpu temp was not too high. It was only possible when i plugged the power cable. The 3Dmarks 11 scores: 1150, and what im using:1090

    It's not advisable to run it on battery, you'll just shorten the lifespan if the battery

    Thanks Mobius, I haven't known this before. That is the reason, that turn off...
    I think 1150 will be stable :))

    Check earlier post, 2 people have overclocked their Y580. You can PM them.
