Configure Memory
This motherboard supports one Dual Channel to your memory. Note that you can use normal DDR memory for Dual Channel to work. Also note that for Dual Channel to work 2 modules of equal size and specifications have to be installed.
The largest memory capacity possible is 3GB. On this motherboard, DRAM speed can be set independent from the CPU front side bus speed. Note that when installing 3GB of memory, your total memory will be less than 3GB. The reason for this is that the BIOS, PCI and AGP cards claim part of your CPUs address space.
Memory Configuration Table
If you want to use the Dual Channel feature, please follow the memory configuration table below:

Installing your memory in a combination different from the table above will still allow your system to work. The Dual Channel feature will not work then however.
Check page5 (motherboard layout) for more info on the location of A1 & B1 DIMM slot.
Memory frequency Table
Depending on the front side bus (FSB) frequency of the CPU, you can run memory of different speeds. Please look at the table below for details:

*When using a 800 MHz FSB CPU and PC2700 DDR DIMMs, the memory frequency runs at 320 MHz (instead of 333 MHz) due to chipset limitations.
