Thanks for sharing your results.. yeah Gigabyte slightly slower on latency, but it might be due to the Crucial Ballistix PC2-8500 modules/Team PC2-10400 modules used as I have moved onto DFI DK X48-T2RBS Plus for testing and using Team PC2-10400 vs Crucial Ballistix PC2-8500 Tracer, at same 7.5x533FSB 5:6 639Mhz 5-5-5-9 timings, there's a noticeable difference in everest latency - Team ~46.8ns vs Crucial ~46.1ns.
I'll have those results in a DFI DK X48-T2RSB Plus thread later this week
