Memory tests
Memory bandwidth, according to ScienceMark 2.0, is roughly analagous to Intel's 925 XE chipset. Both boards are run with identical memory timings, too. NVIDIA's nForce4 SLI chipset always scores well here.
Latency has always been another AMD Athlon 64 forte. What's more interesting, however, is the slight lead eked out by NVIDIA's first Pentium 4 chipset.
Nothing really to choose between the competing LGA775 chipsets in Pifast. NVIDIA appears to have got its memory controller right first time.
