Only Error Checking and Correcting unbuffered DDR2 DIMMs are supported and must be either x8 or x16 width. Memory upgrades
are accomplished by adding DIMMs of the same or varied sizes. The Intel chipset supports both PC2-5300 DDR2-667 and the PC2-
6400E DDR2-800 ECC unbuffered memory. It is suggested to not mix ECC and non-ECC memory.
For best performance the total amount and type of memory loaded into Channel A and Channel B should be the same. If it is not,
your computer will see all the RAM installed but will run the memory controller at a lower performance mode. Although not required,
for best performance add the memory in pairs rather than as a single DIMM (two 512 MB DIMMs will have better performance than
a single 1 GB DIMM). Also, add the memory into both channels (e.g. one in socket 1 and one in socket 3) to take advantage of dual
channel performance. If you have unused slots within a channel, make them socket 2 and socket 4. This provides the best margin for
the memory bus. If you are only using 1 DIMM, install it in socket 1.
