Installing Memory Modules; Connecting Front Panel Cable - AOpen AK89 Max Easy Installation Manual

6. Installing Memory Modules

This motherboard has three 184-pin DDR DIMM sockets that allow you to install
DDR266/333 memory up to 3 GB and DDR400 memory up to 2GB. Non-ECC DDR RAM is
supported. Otherwise, it will cause serious damage on memory sockets or RAM module.
Please follow the table below to install RAM modules. Newly implemented function, the
Voltage of memory on this motherboard is adjustable from 2.5V to 2.85V for over clocking
purpose.

Note: Due to the limitation of memory controller in the Athlon 64 CPU,
we do not recommend you to install three DDR333/266 modules.
DIMM 2 DIMM 3
Tip: "X8" means that each
chip on the module bank
is 8 bits, and "X16" means
each chip is 16 bits. We
know that each memory
bank is 64 bits. Therefore,
if a memory module has 8
chips on each bank it is
"X8", and if there are 4
chips on each bank, it is
"X16".

7. Connecting IDE, Floppy Cables
Connect 34-pin floppy cable and 40-pin IDE cable to floppy connector FDD connector. Be
careful of the pin1 orientation. Wrong orientation may cause system damage.

8. Connecting Front Panel Cable

Attach the power LED, speaker, and reset switch connectors
to the corresponding pins. If you enable "Suspend Mode"
item in BIOS Setup, the ACPI & Power LED will keep
flashing while the system is in suspend mode.
Locate the power switch cable from your ATX housing. It is
2-pin female connector from the housing front panel. Plug
this connector to the soft-power switch connector marked
SPWR.
