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. This motherboard also supports ECC (error correcting code) memory DDR modules.

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:

CPU FSB	Memory Frequency		DDR DIMM Type
(MHz)	(MHz)
400	266	PC2100
533	266 or 333	PC2100 or PC2700
800	400 or 320*	PC3200 or PC2700

*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.

Step 3 Installation of Expansion Cards

The motherboard has 1 AGP slot and 5 PCI slots.

1.Read the related expansion card’s instruction document before inserting the expansion card into the computer.

2.Press the expansion card firmly into the expansion slot on the motherboard.

3.Make sure the metal contacts on the card are seated in the slot.

4.Replace the screw to secure the slot bracket of the expansion card.

5.Install required driver for the operating system you use.
