    Lately (last two weeks) my gpu has been dowclocking itself, that wouldnt be problem if it wasnt happening ingames (wow, wc3, hl2), even with powerplay off gpu still downcloacks itself to 392/250 from 425/380 and funny thing is, gpu alone swaps between those modes arounde once per minute. also when i alt+tab gpu clocks itself back to 425/380 :confused: (all this is happening while ingame)

    now that isnt problem in wc3, but in hl2 and wow couses low fps (3-4 )instead of regular 40+ making games unplayable

    i am using windows 7 x64, with all the leatest updates, didnt test if this happens on xp but willing to try, problem is i lost my recovery cd-s :S

    Week b4 this started to happen i used mobility driver moder and instaled catalyst 9.3, noticed significal fps boost in wow and hl-2, even tryed fresh win instal with vista64 drivers for gpu from hp page (very old drivers) still it didnt solve my problem, mbo has latest bios availible from hp.

    Some help would be awsome as i'm rly out of options and what to do, and rly dont feel like reinstaling windows once again :(...

    could i somehow disable powerplay or owerride it with ati tray tools? problem is i cant run any 3d aplication if att is on :confused: they just dont wanna start.

    EDIT: problem started a week after i moved from win7x64 rc, to win7 x64 ultimate

    Are your sure your laptop isn't overheating? It sure sounds like it does.

    dont know for gpu temps for sure, but cpu never goes over 40, i keep it undervolted, and fan alone spins at half speed most of the time

    any way i could know if my heatpipe "died"?

    Have you tried Rivatuner? It's supposed to work with the ATI X1600, though I haven't tried it on my NC8430. I do use it on my 8510w (Win7 x86) with Nvidia 570M that would mysteriously downclock while gaming until I installed Rivatuner and forced it not to.

    Regarding the possible overheating...you could try putting new thermal paste on the GPU. I have an NC8430 (WinXP) and did this, and it reduced my temperatures substantially. You can also remove the keyboard (easy) and clean out any dust in the cooling system.
