Important notes on memory configurations

1. Installing DDR DIMMs other than the recommended configurations

may cause memory sizing error or system boot failure. See Table 1

for the recommended configurations.

2. Install only identical (the same type and size) DDR DIMM pairs

using the recommended configurations.

3. Make sure that the memory frequency matches the CPU FSB

(Front Side Bus). Refer to Table 2 below.
