Memory

Intel 925X Express chipset

DDR-2 SDRAM ECC MEMORY
Only unbuffered DDR2 DIMMs are supported and must be either x8 or x16 width. 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 (PC2-4200) DDR-2 memory or non-ECC and ECC 400 MHz (PC2-
3200) DDR-2 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. 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.
CAUTION:
Mixing speeds will mean that the memory runs at the speed of the slowest DIMM.
Do not mix ECC and non-ECC memory. The system will not boot if ECC and non-ECC DIMMs are mixed.
Do not mix single-sided and double-sided DIMMs. Both sides of a double-sided DIMM must have the same memory size. Each rank
(side) of the DIMM must be the same size.

MAXIMUM MEMORY

Supports up to 4 GB of DDR-2 SDRAM.
