2-8 Chapter 2: Basic installation
2.6 Installing a DIMM
The system motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline
Memory Module (DIMM) sockets (DIMM_A1 and DIMM_B1, Yellow) and two
Double Data Rate 3 (DDR3) DIMM sockets (DIMM_A2 and DIMM_B2, Black).
The following figure illustrates the location of the sockets:
• This mother board supports either DDR2 or DDR3 DIMMs . Do NOT install
both DDR2 and DDR3 DIMMs at the same time on this motherboard.
• Installing DDR2/DDR3 DIMMS other than the recommended configurations
may cause memory sizing error or system boot failure. Use any of the
recommended configurations in the table on the next page.
• Install only identical (the same type and size) DDR2 DIMMs in DIMM_A1
and DIMM_B1, and DDR3 DIMMs in DIMM_A2 and DIMM_B2.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from the
same vendor.
• When installing total memory of 4GB or more, Windows 32-bit operation
system may only recognize less than 3GB. Hence, a total installed memory
of less than 3GB is recommended.
• This motherboard does not support memory modules made up of 128 Mb
chips or double-sided x16 memory modules.
2.6.1 Memory configurations
You may install up to 8 GB system memory using 512 MB, 1 GB, 2GB, and 4 GB
DDR2 DIMMs or 1 GB, 2GB, and 4 GB DDR3 DIMMs.
