    I've been reading that the new MBP's have their x1600's clocked at a faster speed than the originals. I'm wondering if it is now possible to somehow clock the older ones to the new speed? There hasn't been a dramatic design change right? So the older ones should be able to handle the higher clock speeds too right?

    Thanks for any help.

    The new MBP is tested to have the Graphics chip and memory speed at aroudn 400/400 MHz. The old MBP (in Jan) was to ave in the 300 range for both.

    However, given the situtaion with heating issue in the earlier MBP, I would not advise you to overclock your graphics card.

    If you still want to try it, you can download ATI toolkit for WINDOWS. So boot into windows to do that. (unless someone else knows how to do it in Mac OS).

    If you do that will it remain overclocked even when using OS X?

    I just came from playing GTA: San Andreas on bootcamp, sooo fun

    If you do try overclocking it, do it in stages - upclock a bit, then play a game for a while, keeping an eye on GPU temperature and watching out for artifacts. If it looks OK, upclock a little more and then repeat.

    My CD MBP shows a clock speed of 300/300 (actually more like 297/294) in ATItool in Windows. It is easy enough to clock it up to what it is supposed to be clocked at (400/400) without excess heat, although I don't recomend any higher than that, as it is quite easy to overheat your machine.

    I wouldn't want to permenantly clock the cores up, seeing as battery life would take quite a hit, but it is easy to do for gaming at a desk, and it does boost framerates quite a bit.
