gtx 580m overclocking
I use the gtx 580m. Yes, I got it overclocked. And no, I did not and do not consider buying a desktop /no.gif' class='bbc_emoticon' alt=':no:' /> . I have got a Clevo P150 and here is, how I did it:

- I realized, that 580m is based on the full gf114 chip which can handle a lot more than the casual 620mhz.
- I found, that the clevo P150 has no ventilation holes exactly above the gpu. This results in higher tempertures than necessary.
- I drilled many small vent holes into the removable part of the base plate of my P150. This saved me 5-6 degree which I used to do some overclocking.
- Using msi Afterburner I managed to oc the 580m to 682/1364/1650 (10%) and had the same temperatures as before (at the max 92 degree in msi Kombustor / gf114 max should be 99).
- Because Kombustor stresses the card realy bad, I was able to go a litte further ingame (up to 15% - 713/1426/1725) without using an extra fan.

- Listening to redmonke255 (Thank you!) I exchanged the zalman for the coolermaster u2 notepal.
- With this construction I am currently abel to oc the 580m up to 26,5% (785/1570/1900) with 89 C in Furmark (msi Kombustor) and 86 C ingame (I constantly monitor the temps with msi afterburner).
- This gives me about 21-23% more FPS in, for example, Crysis Warhead or Crysis 2 (without ingame problems like freezing or clipping).
- With this settings applied the gtx 580m comes realy close (90%) to the regular gtx 560Ti desktop card (822/1644/2004).

After some testing there is to say:
- Ocing past 22,5% results in minor glitches (flashing textures) in Crysis Warhead and Crysis 2 (both of them good indicator for overclocking on the software side).
- Beware of the powersupply: Each percent oced will cost one watt. While the standard settings demand 160w a card, that is oced about 20% will demand up to 187w (peak).
- Of course I don´t run the card oced all the time. I made several msi Afterburner Profiles and linked them to hotkeys to addapt on the fly.
- I will report any issues or if my card gets smoked...

Please realize, that in posting this I do not recommend, that you should take the same steps as well. If you do anyway you do those things at your own risk.
Remember: Ocing results in loosing your guarantee. I am not responsible if you blow your card or your system.

If you get a notepad cooler like the coolermaster notepal U2, you'd get even cooler temps. You have the small grille at the bottom because that's your regular intake, to take full advantage of the more breathing room you've created you can use the fans to blow air directly to the heatsinks.

Thanks for the hint. Since the pad you recommended is quite cheap, I am going to give it a try... And then I´ll update my report... Thanks again!

Hello,

Very nice topic. Could you please explain more about your voltage settings? I'm not sure how to adjust the voltage in conjunction with the x/y/z.

Feel free to post it here or via PM.

Thank you

EDIT:

I have a Clevo P170HMx with 2920XM, IC7 Diamond on both CPU/GPU and an aftermarket cooling thingy you put underneath your laptop. Idle temperature without cooling tablet wound be around 37-40 degrees Celius. I suppose there is some space for overclocking?

There certanly is some space. But as I wrote in the pm earlier I was able to realize 750/1500/1815 without changing any voltages - which in my oppinion also could be dangerous to the chip as it already gets pretty hot when oced.

Sincerely
