From what I vaguely understand, DDR3 technology basically allows twice as much information to be read during a single access round to the memory, thus technically providing twice as much bandwidth, compared with DDR2.
Technology aside, these are the objects of questions:
- Current: 2x 1024 MBs PC2-6400
- Target: 2x 2048 MBs PC3-10600
Questions are:
1/ Will the DDR3 set function 1.66x times as fast as my current set (if/when the memory load is high enough), given their theoretical maximums (1333 MT/s and 800 MT/s respectively), or am I missing something?
2/ Will DDR3 sticks work on a non-DDR3-supportive mainboard/system? Or will I not even be able to plug the sticks into the memory slots?
3/ Regarding buses, which ones should I attempt to keep in synchronicity? Memory bus + FSB? Anything else, AGP, PCI? And how do I do this?
It seems here that FSB's frequency is a range instead of a fixed number. Should I aim to synchronize the maximum values (333 MHz FSB + PC3-10600 memory)?
Would such information be listed in the CPU's specifications? Such as what I'm suspecting here.
