Asus Motherboard P5PL2 - Manual (Page 33)

ASUS P5PL2 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 configurations
You may install 128 MB, 256 MB, 512 MB and 1 GB unbuffered non-ECC
DDR2 DIMMs into the DIMM sockets.
• For dual-channel configuration, the total size of memory module(s)
installed per channel must be the same (DIMM_A1 + DIMM_A2 =
DIMM_B1 + DIMM_B2).
• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor. Refer to the DDR2 Qualified Vendors List on
the next page for details.
• This motherboard does not support memory modules made up of
128 Mb chips or double sided x16 memory modules.
