Nanoseconds (lower is better)
Memory performance is pretty good - we accept the Gigabyte boards will be faster when overclocked due to their marginally higher base clock, affording a slightly faster CPU-NB function. However at stock speeds the Asus board is certainly more poky than its P7P55D Deluxe brother and squeezes out a few extra MB/s than the MSI GD65 and Gigabyte UD5.

Sisoft Sandra isn't quite so accomodating at stock speeds, but overclocked it more or less matches the UD5 in terms of performance, despite the ~100MHz or so deficit in memory and CPU-NB frequency. The latency also backs this up - the Asus Maximus III Formula shaves a couple of nanoseconds here against the Gigabyte too, however, against the MSI with only a 1,900MHz memory speed it competes equally.
