3.3.3. Memory
3.3.3.1. SDRAM System Memory
The cPCI-DMXS64GX supports three 168-pin DIMM (Dual In-Line Memory Module)
sockets for memory configuration from 256MB to 1.5GB of Synchronous DRAM in 4HP
configuration and from 64MB to 1.5GB in 8HP configuration.
The memory characteristics must conform to the following:
1.15 inch height, 168-pin DIMM.
Standard 3.3V only.
64-bit and 72-bit modules, single-sided or double-sided.
Unbuffered 100MHz (SDRAM).
Serial Presence Detect (SPD) EEPROM.
Errors Checking and Correction (ECC) capabilities or parity bit with 72-bit
modules.
Compliant with Intel's PC SDRAM Unbuffered DIMM Specification (100MHz)
Rev. 1.0.
Modules can be installed in any socket and order. The total system memory is equal to the
sum of the memory module size installed in the three DIMM sockets.
CAUTION
When populating with more than one memory module, each socket must
be installed with the same memory type (64/72-bit), however the capacity
of each module may be different from the other.
