Hi all so i was wondering about overclocking 640m LE edition laptop gpu, so i found this after all

http://www.youtube.com/watch?v=93bZHFRlRVc

It is 2gb DDR3, i used MSI afterburner (like in video) now i downloaded nvidia inspector
and i got this

1661049_484817164977076_1967022780_n.jpg


my temp is 42 degrees (doing facebook listening to music etc some little programs), is this fine? Should i go for more memory clock speed? Help me out pls, im playing bf4 on high with some fps drops, ill drop it to low/medium. 4gb RAM DDR3 and i3 3110m @2.4ghz, help me out pls or should i even drop clocks to normal or leave like this?

As I've already stated :\ The 640M is a weak card as it is, OCing it will only get you a few extra single digit FPS at best, it won't push you into playing the games at much higher framerates.

Honestly laptop cards don't have that much overclock potential. That's 42C when idling. Check what your temp is while playing BF4. Truth be told you probably don't have that much OC headroom without hitting the thermal throttle limit of the GPU chip.

56C while playing bf4, when its idle like now its 44C, it is 405 mhz while idling i dont know does it boost to 1140 mhz because in OCCT program it writest MAX 1140 for Gpu Mem #1

The 405 to 1140 MHz you're looking at is the Memory Clock. You want to raise your GPU Clock speed (The one that tops out at 705 MHz). The Memory Clock has much less OC potential, because usually the memory chips on the GPUs are run at the max speed they're designed for to begin with. If you're going to raise it any more than you already have, I would raise the GPU Clock, not the Memory Clock. Truth is the 640M isn't meant to play BF4 on High settings without frame drops, so the performance you're getting is expected.

I wouldn't try raising it too much more though, because once the 640M hits its power limit, it will throttle itself down hard. The 600-series cards use power limits for GPU Boost, not temperature like the 700-series do, so if your 640M starts sucking too much power it will throttle itself hard, and you'll see bigger frame drops in those scenarios.
