I'm going to buy a Core 2 Quad Q9550, which has a FSB of 1,333 (333x4). For the sake of this argument (and assuming cost is not a facotor), if I HAVE to choose one of the following memory configurations:
DDR3 at 1,333 CAS 6 (FSB-to-DRAM = 1:2)
DDR2 at 667 CAS 5 (FSB-to-DRAM = 1:1)
which would provide faster system performance (all other factors held constant), and why?
What I really want to know is:
- Does running a FSB-to-DRAM in excess of 1:1 provide a faster setup, or is the extra memory bandwidth wasted due to the FSB bottleneck?
- If it is wasted bandwidth, then wouldn't the slightly lower latency DDR2 provide slightly better performance than DDR3 in this case?
