2. HARDWARE SETUP

2.5 System Memory (DDR DIMM)

This motherboard uses only Double Data Rate (DDR) Dual Inline Memory Modules
(DIMMs). Two sockets are available for 2.5Volt (power level) unbuffered/registered
Double Data Rate Synchronous Dynamic Random Access Memory (DDR SDRAM)
of 64MB, 128MB, 256MB, 512MB, 1GB to form a memory size between 64MB to
2GB. One side (with memory chips) of the DIMM takes up one row on the motherboard.
DDR DIMMs support both ECC (Error Correction Code, typically used in servers)
and non-ECC (used on desktops/laptops) and are available in both registered (typi-
cally used in servers) and unbuffered (typically used in PCs) versions.
NOTE: The DDR memory bus runs at the same frequency as the CPU front side bus.
Install memory in any combination as follows:
DIMM Location
Socket 1 (Rows 0&1)
Socket 2 (Rows 2&3)

2.5.1 General DIMM Notes

• DIMMs that have more than 18 chips are not supported on this motherboard.
For the system CPU bus to operate at 200MHz/266MHz, use only PC1600-/
•
PC2100-compliant DIMMs.
• motherboards support SPD (Serial Presence Detect) DIMMs. This is the memory of
choice for best performance vs. stability.
• BIOS shows SDRAM memory on bootup screen.
• Single-sided DDR DIMMs come in 64, 128, and 256MB; double-sided come in
128, 256, and 512MB.
WARNING!
Be sure that the DIMMs you use can handle the specified DDR
SDRAM MHz or else bootup will not be possible.
