Intel SX220 manual Processor, Memory, Add-in Board Slots

Processor

The SCB2 motherboard accommodates one or two Intel Pentium III processors with 512k cache in the FC-PGA2 package. This processor uses the 0.13 micron technology and offers advanced performance. The processor external interface operates at a maximum of 133 MHz.

Memory

The system board contains six 168-pin DIMM slots each supporting 72-bit ECC (64- bit main memory plus ECC) registered SDRAM DIMMs (PC-133 compatible). Memory is two-way interleaved and partitioned in three banks. You may install a minimum of 128 MB (64MB x 2) and as much as 6 GB.

The controller automatically detects, sizes, and initialises the memory array, depending on the type, size, and speed of the installed DIMMs, and reports memory size and allocation to the server via configuration registers.

NOTE: Use DIMMs that have been tested for compatibility with the server board. Contact your sales representative or dealer for a current list of approved memory modules
