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?
