System memory
1.7.1 Overview
The motherboard comes with four 184-pin Double Data Rate (DDR) Dual Inline
Memory Modules (DIMM) sockets.
The following figure illustrates the location of the sockets:
• If you installed four 1 GB memory modules, the system may detect less
than 3 GB of total memory because of address space allocation for
other critical functions. This limitation applies to Windows
®
XP 32-bit
version operating system since it does not support Physical Address
Extension(PAE)
• Installing DDR DIMMs other than the recommended configurations
may cause memory sizing error or system boot failure. Use any of the
recommended configurations in Table 1.
• In dual-channel configurations, install only identical (the same type and
size) DDR DIMM pairs for each channel.
• Always install DIMMs with the same CAS latency. For optimum
compatability, it is recommended that you obtain memory modules from the
same vendor.
• DIMMs installed into any three sockets will function in single-channel mode.
1.7.2 Memory configurations
You may install 64MB,128 MB, 256 MB, 512 MB, and 1 GB DDR DIMMs into the
DIMM sockets using the memory configuration in this section.
