other system components. Failure to do so may cause severe damage to
both the motherboard and the components.

modules first. Long AGP cards, when installed, may interfere with the
memory sockets.

cause memory sizing error or system boot failure. Use any of the
recommended configurations in Table 1.

and size) DDR DIMM pair on sockets of the same color.

compatibility, it is recommended that you obtain memory modules from the
same vendor.
