Even in its current adolescent state the Asus P5Q BIOS is wonderful to work with – everything just seems to run as expected. With the memory timings trimmed tightly, and performance options like the Transaction Booster and the tRD tweaked to 5 with phase pull-ins enabled the P5Q starts to really sing. We were missing the Command Rate option still, but even then from the graphs above we've still managed to pull down the latency to a low 66ns, and while the EP35-DS4 remains close the copy performance is far greater on the P5Q – this is particularly important for things like games.

In these raw benchmarks, only the Gigabyte X48T-DQ6 (which is some £50 more expensive and features DDR3) outperforms it, however the write performance remains consistent throughout the top to bottom of the boards tested.

Sisoft Sandra shows up as one better by reporting the P5Q memory latency closer to that of DDR3 than the other DDR2 boards, with its latency below that of everything.
