Intel SAI2 PGA-370 Dual Xeon ATX Server Motherboard

SKU CH-4J8E-JM9XP MPN SAI2

Supports dual Xeon processors with four DDR SDRAM slots and six expansion slots

  • CPU TypeDual Intel Xeon
  • Dual Xeon support for parallel workloads
  • PGA-370 socket fits Pentium III CPUs
  • Four DDR SDRAM slots accept PC133 memory
  • 133 MHz memory bus for data throughput
  • ATX form factor fits standard server chassis

Dual Xeon server board

The Intel SAI2 is an ATX server motherboard built for dual Intel Xeon processors in PGA-370 sockets. It targets administrators maintaining or repairing legacy dual-processor systems that require this specific platform. Buyers needing modern instruction sets, current memory standards or contemporary expansion interfaces will not find them here.

PC133 memory ceiling

Four memory slots accept DDR SDRAM at 133 MHz to a maximum of 4 GB using the PC133 standard. This ceiling reflects the chipset design of its era and cannot be exceeded by adding larger modules or faster sticks. Systems requiring more memory bandwidth or capacity must use a different platform.

Six expansion slots

Six total expansion slots provide room for period-appropriate add-in cards such as storage controllers or network adapters. The slot count supports a typical server workload of the time but offers no headroom for modern high-bandwidth peripherals or multi-GPU configurations. Builders needing current I/O standards should look elsewhere.

Questions about this item

Should I choose the four-slot DDR SDRAM version or a board with more slots?

This board has four memory slots accepting PC133 DDR SDRAM up to 4 GB total, so the slot count is fixed for this model.

What does the 133 MHz memory speed mean once the board is running?

The memory bus runs at 133 MHz, so installed PC133 modules will operate at their rated frequency without down-clocking.

How does the PGA-370 socket limit which processors I can install?

The PGA-370 socket accepts Pentium III and compatible Xeon CPUs in that package; other processor families will not fit.
