Technical Specifications
Technical Summary
This MSI MS-91A3 Rev 0A motherboard, dated March 18, 2008, is a dual-socket workstation platform built around the Intel LGA-1366 Nehalem-EP architecture with the Intel TYLERSBURG 36D and ICH9/10R chipset. The board supports up to 12 DDR3 modules across 6 memory channels, powered by ISL6312CR and ISL6545 regulators. Dual CPU VCORE is managed by ISL6334CRZ controllers, while VTT power is handled by ISL6314CRZ. The system integrates an SMSC/SCH5617C LPC SIO for legacy I/O, an ADI 1984A HD Audio codec, and an Intel 82567LM Boazman PHY for LAN. IEEE 1394 connectivity is provided by a TI TSB43AB22 controller. Thermal monitoring is managed by ADT7490 and ADT7462 sensors. The BIOS is stored on a SPI Flash device. Power delivery includes multiple rails using ISL6622, ISL6612, APL1084, and NTMFS4841 components.
