PCI-946-1 and P3S440BX Technical Reference manual
3-14
3.5.3. Installing the Memory
3.5.3.1. SDRAM System Memory
The PCI-946-1 and P3S440BX support three industry standard 168-pin DIMMs (Dual In-
Line Memory Module) sockets for memory configuration from 32MB to 768MB of
Synchronous DRAM.
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,
Only the P3S440BX SBC is compliant with Intel’s PC SDRAM Unbuffered
DIMM Specification (100MHz) Rev. 1.0. The PCI-946-1 FSB runs at
66MHz.
At least 32MB of memory must be installed on the board for proper operation. 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.
✎
NOTE
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.
