Intel 925X Express chipset
DDR-2 SDRAM ECC MEMORY
It is not necessary to add memory in pairs. Memory upgrades are accomplished by adding single or multiple DIMMs of the same or varied sizes. This
chart does not represent all possible memory configurations. The Intel 925X chipset supports ECC 533 MHz (PC2-4300) DDR-2 memory or non ECC
and ECC 400 MHz (PC2-3200) DDR-2 memory.
For best performance the total amount 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. 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. Mixing ECC and non-ECC memory will mean that all memory will run as non-ECC.Mixing speeds
will mean that the memory runs at the speed of the slowest DIMM.
MAXIMUM MEMORY
Supports up to 4 GB of DDR-2 SDRAM.
