CHAPTER 2 –Hardware Installations
SPI-8450-LLVA 9
2.3 Main Memory Installation: DIMM1/2
The SPI-8450-LLVA Industrial CPU Card supports two single-side or double-sided
DDR200(PC1600)/266(PC2100) unregistered, Two 184-pin DIMM sockets for a maximum
total memory of 2GB. Using the non-ECC DDR SDRAM DIMMS.
The CPU card supports the following memory features:
y 2.5V(only) 184-pin DIMMs with gold-plated contacts
y 200 MHz (PC1600)/266 MHz (PC2100) DDR SDRAM
y Non-ECC DIMMs
y Unbuffered, unregistered single-sided or double-sided DIMMs
The CPU card supports single or double-sided DIMMs in the following sizes:
DIMM
Capacity DDR SDRAM
Density DDR SDRAM Organization
Front side / Back side Number of

Note: All memory components and DIMMs used with the SPI-8450-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.
