Arkon AIMB-256 user manual Memory Configurations, Installing a DDR2 Dimm

1.5.2Memory Configurations

You can install 128 MB, 256 MB, 512 MB, 1GB and 2 GB DDR2 SDRAM DIMMs into the SODIMM sockets using the memory configurations in this section.

Note! ! Installing DDR2 DIMM other than the recommended configurations may cause memory sizing error or system boot failure. Use any of the recommended configurations.

!Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor.

!Due to chipset resource allocation, the system may detect less than 1 GB system memory when you installed one 1 GB DDR2 memory modules.

!This motherboard does not support memory modules made up of 128 Mb chips or double-sided x16 memory modules.

!Make sure that the memory frequency matches the CPU FSB (Front Side Bus). Refer to the Memory frequency/CPU FSB syn- chronization table.

Note! ! Memory frequency/CPU FSB synchronization.

CPU FSB	DDR 2 DIMM Type	Memory Frequency
533/800 MHz	DDR2 533	Max clock Freq: 266 MHZ; 533 Mb/s
	DDR2 667	Max clock Freq: 333 MHZ; 667 Mb/s

1.5.3Installing a DDR2 DIMM

Caution! Make sure to unplug the power supply before adding or removing DIMMs or other system components. Failure to do so may cause severe damage to both the motherboard and the components.

1.Locate the DIMM socket on the board.

2.Hold two edges of the DIMM module carefully, and keep away of touching its connectors.

3.Align the notch key on the module with the rib on the slot.

4.Firmly pressing a module into the socket snaps it into the mounting notch and engages the ejectors. Do not force the DIMM module in with extra force as the DIMM module only fit in one direction.
