ASUS Pundit P3-PH5
2.5 Installing a DIMM
The system motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline
Memory Module (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 gure illustrates the location of the DDR2 DIMM sockets.
2.5.1 Memory congurations
You may install up to 8 GB system memory using 256 MB, 512 MB, 1 GB, and 2
GB DDR2 DIMMs.
• Installing DDR2 DIMMS other than the recommended congurations
may cause memory sizing error or system boot failure. Use any of the
recommended congurations in the table on the next page.
• Install only identical (the same type and size) DDR2 DIMM in DIMM_A and
DIMM_B.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from the
same vendor.
• Due to chipset resource allocation, the system may detect less than 4 GB
system memory when you installed four 1 GB DDR2 memory.
• This motherboard does not support memory modules made up of 128 MB
chips or double-sided x16 memory modules.
