    8800m gtx OC


    Okay, me and Fleffy forgave each other, but he's gonna have to sleep under his bed, and I'm gonna sleep on his bed as his punishment for 1 week. Anyway, me and Fleffy decided to OC each other's m1730's 8800m gtx (both of us just got them 1 month ago. Worked like a charm, no artifacts. Any body here who also OC'd their GPU? Just wondering, so that you can give me and Fleffy some advice on how to keep our laptop safe, but we have enough cooling (fans in a box with ice blowing towards our pc)

    ice blowing on your PC is retarded, the ice will sublimate and condense inside of your machine and destroy it.

    just follow the regular steps, overclocking is a process that is made to take days. Clock it up 3-8mHz, play for 2-4 hours (in windowed mode with a GPU temp monitor), repeat until you reach a stable speed, when you reach a good speed at a stable temperature play it full screen on full res for a couple of hours, if it fucks up clock it back, if not keep it.

    sorry for the same advice you could get anywhere else, but its the only way to do it.

    I have my 8600 512 DDR2 running the same FPS as most stock 8800's because of overclocking and fine-tuning.

    Oh, ok, I'll remove the ice, but the fan's good, right? Anyway, the 8800m gtx default values are 600/1250/800 which is lower that the normal 8800 gtx. I OC'd to 625/1500/950 and it's slightly faster than an 8800 gt, gts and gtx. It's not faster than the gts (2nd version) http://www.nvidia.com/page/geforce8.html

    The fans are always good, the next step would be if you know how to take it apart and remove the heat sink on the GPU. If so you could replace the stock cooling compound with arctic silver, than that should give you a 10-30% cooling increase.

    The problem with laptops is that they are still propietary, and as such nobody bothers to take them apart, so there are no parts available other than processors and ram, whearas if you were working with a desktop you could add as many fans as you want, get a zalman cooler to replace the stock ones on your VGA.

    another problem with most laptops is that the power supply is already at it's max because it is limited to the battery, so you can't overclock it much due to said voltage limitations.

    that being said, most video cards can get to about a 50-70% increase in power, so it should be safe to keep increasing it, but keep in mind that if you overclock it past the maximum voltage of the laptop's PSU than you would run into some problems, so be sure to increase one clock at a time, by a small amount, and test it thoroughly first.
