Chapter 2: Hardware information
2.5 System memory
2.5.1 Overview
The motherboard comes with two Dual Inline Memory Module (DIMM)
sockets. These sockets support up to 2GB system memory using 168-pin
unbuffered non-ECC PC133/100 DIMMs.
2.5.2 Memory configurations
A DIMM is keyed with a notch so that it fits in only one direction. DO
NOT force a DIMM into a socket to avoid damaging the DIMM.
Install DIMMs in any of the following combinations.
DIMM Location 168-pin DIMM (SDR) Total Memory
Socket 1 (Rows 0&1) 64MB, 128MB, 256MB, 512MB, 1GB x1 =
Socket 2 (Rows 2&3) 64MB, 128MB, 256MB, 512MB, 1GB x1 =
Total system memory (Max. 2GB) =
DIMM Notes
• This motherboard supports Serial Presence Detect (SPD) DIMMs. This is
the memory of choice for best performance and stability.
• SDRAM chips are generally thinner with higher pin density than EDO
(Extended Data Output) chips.
• Single-sided DIMMs come in 16/32/64/128/256MB densities; double-
sided DIMMs come in 32/64/128/256/512MB densities.
