3.2Main Memory

ADE-9040 provides 2 DIMMs (240-pin Dual In-line Memory Module) to support 1.8V DDRAM (Synchronized DRAM) as on-board main memory. The maximum memory size is 256 MB ~ 4 GB with using 256MB/512MB/1GB technology. Supports up to 2 double sided DIMMs at DDR2 533/667/800MHz. The memory architecture adopts 128-bit data interface to support for x8 and x16 DDRAM(DDR2) device width. In addition, it only supports Non-ECC memory.

For system compatibility and stability, don’t use memory module without brand. You can also use the single or double-side DIMM .The two DIMMs can be out of order. You can install different size of DDRAM module on DIMM1, DIMM2 or all to boot up system.

Without out the contact and lock integrity of memory module with socket, it will impact on the system reliability. Follow normal procedure to install your DDRAM module into memory socket. Before locking, make sure that the module has been fully inserted into the DIMM slot.

NOTE: For maintaining system stability, do not change any of DDR2 memory parameters in BIOS setup to upgrade your system performance without acquiring technical information.
