    What is the highest stable core clock you guys have gotten with a: 8400, 9200, 9300?

    And what was the highest stable memory (ddr2) speed?

    I currently own a 9200m, and i have a stable oc of 700(core), 500(memory).

    I wish to know because I am getting a new laptop with a 105m with ddr2 (it is based on the 9300). Since it is very new, I can't find any thing on google that relates to overclocking the 105m.

    I've gotten mine to 500, but not stably (fails out on ATiTool).
    460 is about my limit.

    I got a 9300M GS and, well, can't OC it.

    Just one question, is overclocking the shader clock not really useful? At present that's all I could OC, and it improved my 3DMark score by 50 or so..is it negligible when playing games? :D

    I got the same as you on 8600GT, 700/500 but it was stable only in some games and I now I don't keep it like that. I keep it now on 650/440.

    8600m GT - 570/426 I think that's reasonable... no problems on 3dmark, furmark, atitools

    on a 8600M GT my highest stable overclock on memory is 488
    @darthbane I think those guys have DDR3 cards there is no program that will even allow you to clock beyond 600mhz with DDR2 memory

    Remember that when overclocking, stability is more important than be able to run a little time with high clocks.

    For some reason if I up my core clock too high my nvidia drivers crash anywhere from 2 seconds to 20 minutes while playing games. I can only go from 500 on my 9600M GT to about 585 before I start seeing random driver crashes.

    However my memory is very overclockable. I have successfully run Crysis with my mem clock upped from 400 to 550 with almost no temp increase. Gave me 1 or 2 extra frames, but really helped with the minimum framerate (~4-5 more?)

    I still don't understand why I can't up my core clock all the way to 600+. I've seen people get 700. A maximum increase of 85 mhz seems way too low.
