    my win 7 (32 bit), it shows only
    6.6GBps on overclocking. can this
    issue be.fixed at home? is

    The bus rate has nothing to do with your OS (I am running a 7950 with 384bit GDDR5 on x64 OS) are you sure it's GDDR3 and not DDR3? can you post a GPUZ screenshot of the main GPUZ screen?

    Yeah, apples and oranges there... OS bits have NOTHING to due with the memory bandwidth of GPUs.

    Where are you reading this 6.6 GBs value anyway?

    you bought a GDDR3 card and not the GDDR5 the GDDR5 has the 12Mb/s
    card is terrible and slow either way
