What about LM Bench? My dual 2.4's, 2.8's have the E7500 chipset and are reporting 150ns (fastest is 145) with 400mhz FSB and registered ECC RAM (DDR). The 3.06's here have the same chipset as yours, with the same 533mhz FSB, but latency is _still_ at 145ns roughly. Perhaps it is the registered / ECC ram that is slowing things down, although I would not use non-ECC memory on any critical machine.
