For safety's sake, I wouldn't go much higher than 70-75 C. If you are going to OC your notebook, definitely clean the fans thoroughly. The loss of warranty due to really opening the case is no longer and issue, as you mentioned :p. If the temps don't drop much, then I think you won't be able to put a good OC on it, but if they drop dramatically, say into the low-50's, you could definitely get a performance bump.

The means to overclocking regardless of the utility that you use is to start slow and build up. Run the Windows Experience Index, or else some other graphical benchmark to stress-test the system and ensure stability. If the system hangs or the driver crashes, then back off on the OC.

Try a small (say 15 MHz bump to core [30 MHz shader]) and see what happens. If it is stable, add another 5-10 (10-20) MHz and repeat. Once the system starts to act up, back off--use common sense. 🙂 The memory also can be pushed, maybe 20-30 MHz at a time. Don't push the memory and the core/shaders on the same round, that way if something acts up, you know what the culprit is.

The whole OC game is a bunch of tweaking, and there is no better way to learn it than to do it. If you don't touch the voltages, there is no risk of damaging your system--though you could make it unstable till you reboot. Unlike CPUs, which require BIOS mods to overclock, GPUs are OC'ed by special utilities which are software-only mods. When the system reboots, the vBios will reset the clocks back to the defaults, so don't tell the utility of your choice to run at start-up until you have the system confidently stable.

Enjoy! Good luck! ASUS put out on the ROG site a nice little tutorial on OC'ing a desktop card, but the technique is the same.

Thanks a million. Yeah that was the guide I was using. Its the first time I will OC but better to blow up the M50 than the G75 :D. Hopefully with your instructions everything will be safe. 😉

As long as you do what I said and don't increase voltages, there is zero risk. The worst that happens is your computer gets hot and shuts down--not a big deal. Just use common sense and don't run anything important while OC'ing your notebook; I look forward to seeing/hearing the results in the future!

P.S. Can you explain your avatar?

Ah first time somebody asks. I am a doctor, just graduated and I played Sims (seemed like a good choice last year). Hence the lack of time for playing games in the last years :D. I will let you know in a couple of weeks how it went the OCing. Thanks

Congratulations on graduation! That is a major achievement, now we have two doctors on the ROG forums. 🙂 Now we know who to go to when we spill liquid nitrogen on our OC'ing little paws. 😛

Thank you very much 😉 I dont know who the other doctor is but I would like to. Yes now that I have more time I want my revenge on the video games MUAHAHAHAH :p. I hope the only advice people will need is about gaming 😛 but at this time everyone here is a better expert than me.

PS- In case of liquid nitrogen accidents just immerse the hands in water 39-42º C (102-108 F). It hurts the unfreezing but it is necessary to prevent more damage and dont forget to call Emergency 112 in Europe (911 US). If you cant because both hands are affected just try to find somebody to call for you. Don't use any clothes to cover the injuries because they can attach to the skin, use the hot water only or some other source of heating that does not go over 42º C or you risk getting a heat burn in addition to your cold burn. Prepare for blisters, infections and some scars over the next weeks. 😉 Just in case.

The other doctor is @DocNRock, a new overclocker, except he is doing desktops. You can find him in General Discussion sections. Oh, and thanks for the cold burn advice, just one thing, a lot of USA guys don't know SI units, so here is the temperature: 102-108 Fahrenheit. Thank you again, I just thought I would convert it for the USA people who aren't as comfortable with Celsius. Its something about the system you grow up with, I understand, that determines not how you work problems, but how you think.
