ASUS P5MT-S 2-13
2.4 System memory
2.4.1 Overview
The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline
Memory Modules (DIMM) sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has
a 240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are
notched differently to prevent installation on a DDR DIMM socket.
The figure illustrates the location of the DDR2 DIMM sockets:
2.4.2 Memory configu rations
You may install 256 MB, 512 MB, 1 GB, and 2 GB unbuffered ECC or
non-ECC DDR2-533/667 DIMMs into the DIMM sockets.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from
the same vendor. Refer to the DDR2 Qualified Vendors List on the
ASUS web site.
• When installing one or two DIMMs, install the DIMM(s) to the blue
slots (DIMM_A2/DIMM_B2).
• Three DDR2 DIMMs intalled into any three memory sockets will
function in single-channel mode.
