Only unbuffered DDR2 DIMMs (ECC unbuffered or non-ECC) 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 975X chipset supports both PC2-5300 DDR2-667 non-
ECC and ECC unbuffered 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.
