•
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 identical
identical identical
identical (the same
type and size) DDR DIMM pairs for each channel.
•
Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor.
• Double-sided x16 modules are not supported in this motherboard.
• Due to chipset resource allocation, the system may detect less than
4 GB of system memory when you installed four 1 GB DDR memory
modules.
• Due to chipset limitation, DIMM modules with 128 Mb memory chips
or double-sided x16 memory chips are not supported in this
motherboard.
