Other than the layout of a few onboard components, and then the arrangement of some power circuitry, the layout between the S5370 and S5372 is almost identical. In the upper right hand corner of both motherboards are the two LGA-771 sockets. The processors supported include the 5000 Dempsey series and 5100 Woodcrest series, with respective FSBs of 1066MHz and 1333MHz.
Beneath the second CPU socket on the S5372 motherboard is a PCI Express x4 slot, though the signal provided is PCI-E x8. This slot can be used for such things as PCI Express disk controllers or similar devices that do not require an external interface. In the corner on both of the motherboards is the Southbridge, which happens to be the Intel ESB2. The Southbridge provides the functionality for the Serial ATA ports and other interfaces. Both motherboards have a small aluminum heatsink covering the Southbridge. Also in this corner of the motherboard is the six Serial ATA ports and IDE ATA-100 connector. Both motherboards support SATA RAID 0, 1, and 5 modes.
