Memory
915G Express chipset
DDR SYNCH DRAM NON-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 915G Express chipset supports PC2-3200
(DDR2 400-MHz) non-ECC and DDR2 PC4200 (533-MHz) non-ECC memory.
For best performance, add in pairs, add in same channel, and do not mix speeds. For dual-channel performance, the total amount of
memory in each channel should be equal. If speeds are mixed, speed will default to the slowest DIMM.
MAXIMUM MEMORY (SLIM TOWER AND MICROTOWER)
Supports up to 4-GB of DDR2 SYNCH DRAM. Above 3-GB, all memory may not be available due to system resource requirements. Not all
memory configurations possible are represented below.
