• Use the blue DIMM slots first.
• 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. For optimum compatibility, it is recommended that you obtain
memory modules from the same vendor. See the DDR400 Qualified
Vendor List (QVL) on page 2-14.
2. Make sure that the memory frequency matches the CPU FSB (Front
Side Bus). Refer to the M e m o r y f r e q u e n c y / C P U F S B M e m o r y f r e q u e n c y / C P U F S B M e m o r y f r e q u e n c y / C P U F S B M e m o r y f r e q u e n c y / C P U F S B M e m o r y f r e q u e n c y / C P U F S B

3. Always install DIMMs with the same CAS Latency.
4. Double-sided DDR DIMMs with x 1 6 x 1 6 x 1 6 x 1 6 x 1 6 (data bus=16bit) memory chips
are not supported due to chipset limitation.
