    Hey guys, I was wondering if you could tell which are the symptoms for overheating of a GPU or Video-Ram (I presmue they are diffrent?). As in, is it the fault of the GPU if there are "Geometry errors", like texture streched half across the screen (some examples of what I mean; I didn't take those pics though) [​IMG] [​IMG] [​IMG]
    This one is not from my PS3 either, but it is from some other guy who seems to have the same problem with a Stock 60GB unit...

    Nevermind the small pixel-errors (which I am pretty sure are actually RAM related, even though I remember having the 9800xt overclocked too much on DOOM3 would give me red small pixel-errors in the shadows, so I'm not all that sure);
    What I am concerned about are those streched textures, is this because the gpu overheats, or because of the video rams high temps?

    I'm not asking this because of my PC, but because of my PS3 which shows some of those lines in VERY VERY few occasions (and only some games) after I finally managed to get the Fan Level to stay at level 2 by applying Arctic Cooling MX-2; (Check this thread for more info: http://forums.techpowerup.com/showthread.php?t=67406)
    My guess is that the Cell is just fine with the heat, but the RSX can't take only fan-level 2 (in fact, forcing the PS3 to fan level 3 "solves" the problem; but I find it kind of uncool to wrap it insinde a towel for a few minutes just to get those lines away... =()

    I applied a bit more MX-2 on the RSX than on the Cell, because it has a bigger heatspreader, and some very small drops on the 4 corners, because that is where the VRAM is located... Should I use more TIM?; I'm pretty sure the amount is right for the cell though, as it really stays in fan level 2 even while folding... :nutkick:

    Anyhow, thanks for your answers.

    It can be from either the memory or the core.

    You cant really tell. Generally they are VRAM problems, but I have gotten the same errors in the past by overclocking my core too much.
    Dixxhead says thanks.

    Well, that's a shame, thanks for the reply anyhow... I hope I can fix it by adding a Notebook-cooler or something below the ps3 (all of those "For PS3"-Fans suck from a loudness point of view).

    I've been recommended some Notebookcoolers in the other thread, but I'm not sure as in how silent and effective they are. I wouldn't wanna spend much more than 50€ either.

    Thanks for the answers. :)
