Review: Quite fast, but too expensive
The first board with the X38 chipset in our labs did well. Of course, you can't expect any speed improvements because it's basically a P35 chipset, but with an additional 400MHz FSB strap. This means it supports 400MHz FSB (1600MHz marketing speech) out of the box and with higher FSBs you don't need the highest overclockable memory modules available to achieve nice overclocks. Of course, this is a feature unsupported by Intel. New features are 2x PCIe 2.0 x16 support for the latest graphics-cards and ECC support for DDR2 or DDR3 memory.
