    Gateway OCed 700MHz GDDR3 to 800MHz for P68xx series GPU?

    I tore apart my Gateway; found that memory chips on GPU were 700MHz rated Samsung K4J52324QE-BC14 chips.

    So GW OCed the chips to get 800MHz? Will the lifespan decrease as a result?

    Wow, that sucks.

    I guess you don't get much of an overclock on top of that right?

    Surprisingly I could get 975MHz on these chips although I don't use such high clocks while gaming.

    The gateway uses DDR2 667MHz, PC2-5300. The memory runs at 667MHz not 800MHz, no overclocking involved.

    He is talking about the video memory. Not the system memory.

    So anyone out there who's gonna disassemble their P78xx or P79xx?
    To see if GW really OCed the chips on those models.

    While you have it open, maybe pin mod the PLL. You could probably get to 4ghz.

    Oh it's already reassembled - the process takes just about over 2 hours.

    I believe a PLL mod is not possible on my model. :rolleyes:

    Will the system accept 800MHz memories?

    Thanks, don't know how I missed that.

    A hardware PLL mod should be possible. Ours is hardlocked against overclocking but physically modding it should enable overclocking through software.

    The memory is limited to 667Mhz memory if you use 800Mhz memory on the system it will downclock to 667Mhz. We are talking about system memory now, right? LOL.

    One last thing- can i swap out the mobo and cpu for a P79xx series mobo+cpu if they eventually die?
    It seems that the screw holes are in the right position.

    Will I need new heatsinks or GW has been using the same HS for P68xx thru P79xx?

    I seem to recall reading in these forums that somewhere in the production run of the 7811's, a larger CPU heat sink was found in some units (more machined copper in contact with the CPU). It was hoped this was in preparation for releasing a Quad-Core version. As there is now a quad-Core version of this series available (IIRC), perhaps someone can (or already has) verify if the larger CPU HS in some 7811's is the same as what is now in the Quad-core model.

    Or I could be smoking something.... (probably the cat hair in my CPU fan) lol
