2.2 Main Memory Installation: DIMM1 / DIMM2
The SPI-8150/1-LLVA Industrial CPU Card supports two dual inline memory
module (DIMM 168-pin) sockets for a maximum total memory of 512MB. Using the serial
presence detect (SPD) data structure, programmed into an E
2
PROM on the DIMM, the BIOS
can determine the SDRAM’s size and speed. Minimum memory size is 16MB; maximum
memory size is 512MB. Memory size and speed can vary between sockets.
The CPU card supports the following memory features:
• 168-pin DIMMs with gold-plated contacts
• 100MHz SDRAM
• Non-ECC DIMMs
• 3.3V memory only
• Unbuffered single or double-sided DIMMs in the following sizes:
DIMM size Non-ECC configuration
16MB 2Mbit x 64
32MB 4Mbit x 64
64MB 8Mbit x 64
128MB 16Mbit x 64
256MB 32Mbit x 64
512MB 64Mbit x 64
Note: All memory components and DIMMs used with the SPI-8150/1-LLVA CPU card must
comply with the PC SDRAM Specification. These include: the PC SDRAM
Specification *memory component specific), the PC Unbuffered DIMM Specification,
and the PC Serial Presence Detect Specification.
