Technical Summary

The MSI MS-7276 motherboard, manufactured by MICRO-STAR INT'L CO.,LTD and dated Monday, October 09, 2006, is built on the Intel Broadwater platform with an Intel G965/Q965 North Bridge and Intel ICH8DO/DH Southbridge. It supports Intel Pentium 4 Cedar Mill/Prescott, Pentium D Smithfield/Presler, and Conroe family processors in the LGA775 package. Memory architecture consists of dual-channel DDR2 across four DIMM slots. The board utilizes an Intersil ISL6312 4-phase PWM controller with ISL6612 drivers for CPU power delivery. The Super I/O and EC/KBC functions are handled by a Winbond W83627DHG chip. Audio is provided by an Azalia ALC883 codec. Networking options include the Ekron-N 82562V 10/100 LAN and Nineveh 82566DC/DM Gigabit LAN controllers. The BIOS is stored on an 8M SPI flash ROM. Expansion includes PCI Express x16 and x1 slots, PCI slots, and onboard controllers such as the VIA VT6307 IEEE1394 and JM20335 Hi-USB to PATA bridge. Document numbers include 601-7276-A10, 601-7276-A20, 601-7276-01S, and 601-7276-03S.
