    What type of memory does the 7900 in the E1705 have? GDDR1, DDR2, GDDR3?

    Also, I ask only as a curiousity and have no idea what implications the answer to the above question will have? What does it mean?

    Thanks

    I've seen that. It lists all three types of memory as options. Which is implemented in the E1705?

    Any particular reason? I've been researching and it seems GDDR3 runs at lower voltages and so would produce less heat which would seem reasonable for the 20W TDP target for the 7900GS.

    On the other hand, I read someone's overclocking journal and it seems the memory clock multiplier is 2x. This is total speculation but does that mean it's DDR2?

    all ddr is 2x, 1,2,3 refers to clock speeds, roughly ddr1 has an effective speed around 400mhz,ddr2 around 800, ddr3 around 1600
