Intel DX38BT @ Trusted Reviews
“Intel’s new DX38BT takes over from the BadAxe 2 D975XBX2 as the king of the Extreme Series line of motherboards. As the model code suggests the DX38BT uses Intels’s own X38 chipset, which supports the latest 45nm Penryn CPUs. However, there’s a fly in the ointment. The Taiwanese motherboard manufacturers have started to release BIOS updates that add support for a 1,600MHz front side bus to their X38 models along with support for 1,600MHz DDR3 memory.”
