Intel X38 Express Chipset Motherboards Ready - From the Bearlake-family

Intel will unveil the high-end version of its Bearlake-family next month – the Intel X38 Express. The new Intel X38 Express replaces the 975X Express, which launched over a year ago with Intel’s Presler Netburst processors. The new chipset introduces new features to Intel’s high-end enthusiast and workstation platform such as PCIE 2.0 and DDR3 memory.

New to the Intel X38 Express is support for dual full-speed PCIe 2.0 x16 slots. The dual PCIe 2.0 slots are compatible with AMD’s CrossFire technology for multi-GPU graphics processing. Motherboard manufacturers are also free to equip Intel X38 Express based boards with a third physical PCIe 2.0 x16 for triple-play physics. Due to chipset limitations, the third physical PCIe 2.0 x16 slot has lesser lanes, with most manufacturers opting for four lanes.

DDR3 is the only officially supported memory for the Intel X38 Express. Intel touts DDR3-1333 memory for X38 Express motherboards. DDR2 memory support has been removed officially from the X38 Express, however, the memory controller can still function with DDR2, just without Intel validation. The DFI LANParty X38-T2R will pair DDR2 support with the Intel X38 Express chipset.

The Intel X38 Express also supports upcoming Intel Penryn-family dual and quad-core processors with front-side buses up to 1333 MHz. The new Penryn family is Intel’s first 45nm processor family, expected to launch in Q1’2008 for consumer desktops. Desktop Penryn-family Core models will launch in early 2008.

 

 

 

ASUS, Biostar, DFI, Gigabyte, Intel and MSI have X38 Express-based motherboards on display at Computex 2007. ASUS plans to release an X38 Express-based workstation board. The upcoming ASUS P5E3 WS Professional pairs the X38 Express with the ICH9R south bridge. The board supports dual-channel DDR3-1333 memory, with no mention of ECC support. The P5E3 WS Professional does not have a third physical PCIe 2.0 x16 slot. ASUS opted for a vanilla orange PCB with the P5E3 WS Professional.
