Install Memory Modules

This mainboard accommodates 184-pin 2.5V unbuffered
Double Data Rate (DDR) SDRAM memory modules. The
memory chips must be standard or registered SDRAM (Syn-
chronous Dynamic Random Access Memory).
This mainboard is capable of auto detecting the type of mem-
ory modules (DDR SDRAM or SDRAM) you have installed
and then automatically adjusting the voltage to the appropriate
level.
Note: This mainboard cannot support two different types
of memory modules simultaneously.
The memory bus can run at 100 MHz or 133 MHz. If your
processor operates over a 100 MHz system bus, you can in-
stall PC100 or PC133 memory modules that operate over a
100 MHz or 133 MHz memory bus. If your processor operates
over a 133 MHz system bus, you can only install PC133
memory modules that operate over a 133 MHz memory bus.
Note: SDRAM provides 800 MBps or 1 GBps data trans-
fer depending on whether the bus is 100MHz or
133MHz. Double Data Rate SDRAM (DDR
SDRAM) doubles the rate to 1.6 GBps and 2.1
GBps. DDR SDRAM uses additional power and
ground lines and requires 184-pin DIMM modules
rather than the 168-pin DIMMs used by SDRAM.
