How high R3 GT 540m

[Greylox]

Just got my 1st M11x, a Red:
i7 2637M 1.7GHz (2.8GHz w/Turbo Boost, 4MB Cache)
8gb Ram (I put in myself because of the stupid prices from dell)
GT 540m 2gb (672mhz stock)

I'm properly pleased with the little beast

...and was interested how far people have overclocked this graphics card. Ive got the laptop on a cooling pad and so far have got a stable 750mhz playing SWTOR for over an hour at max 77degrees c (in a warm room) . Also at what stage might it be worth upping the voltage to it (assuming you can do that with msi afterburner...I've only ever oc'd desktops..this is my first lappy)

( Seems the 550m is just an overclocked 540m aswell http://www.notebookcheck.net/NVIDIA-...M.41715.0.html.)


Gonna be a bit of an experiment

You can't adjust the voltage on an m11x, it won't let you. There is a bios mod that bumps you up .05 volts though, try that.

ok, gonna see if I can get to 800mhz first, then I'll look into that, thanks

I didn' had the need to play with the 540m OC-ed, but for testing I did several loops of 3d Mark 2006 and 3d Mark 11. Clocks and scores in sig
PS> temps were up to 79-80 degrees celsius.

I've found with mine, with intense gaming for hours, 780mhz seems to be a sweet spot. Temps top out at 78c.

780mhz? I'm running 830mhz with temps maxing at 67c after 3 hours of gaming! (Left 4 Dead 2, Max settings)
