CAUTION:

Please adhere to the precautions and configuration options listed in this section. Failure to adhere to these precautions may lead to CPU card damage.

If only one memory module is installed, install it into the first DIMM slot, i.e., DDRII 1.

Dual-channel DDR only works in the combinations listed in Table 4-1.

DDRII 1 (Ch A)
