1.9.2 Memory configurations
You may install any DDR DIMMs with 64MB, 128MB, 256MB, 512MB, and 1GB
densities into the DIMM sockets.
* For dual-channel configuration (3), you may:
• install identical DIMMs in all four sockets, or
• install identical DIMMs in DIMM_A1 and DIMM_A2
and identical DIMMs in DIMM_B1 and DIMM_B2
1.
Installing DDR DIMMs other than the recommended configurations may
cause memory sizing error or system boot failure. Use any of the
recommended configurations in the table below.
2.
In dual-channel configurations, install only identical (the same type and
size) DDR DIMM pairs for each channel.
3.
Install only DIMMs with the same CAS latency.
4.
Make sure that the memory frequency matches the CPU FSB (Front Side
Bus).
5.
DIMMs installed into any three sockets will function in single-channel mode.
