The final preliminary remark is that not all i955/i945-based mainboards support the 1:1 memory divisor. So, you have to be careful about your choice of the mainboard, not only of the memory modules, in order to build an advanced computer with high-speed memory.

That said, we can at last get to our tests. First, here are some tests that measure the effective bandwidth and latency of the memory subsystem.

As you can see, timings and frequency affect the real performance of DDR2 SDRAM quite heavily. Note that this is conspicuous even despite the limited bandwidth of the processor bus which is no higher than the bandwidth of DDR2-533 SDRAM with Pentium 4 systems.
