*Use only identical DDR DIMM pairs.
*For
•install identical DIMMs in all four sockets or
•install identical DIMM pair in DIMM_A1 and DIMM_B1 (blue sockets) and identical DIMM pair in DIMM_A2 and DIMM_B2 (black sockets)

• *When using 800MHz CPU FSB, PC2700 DDR DIMMs may run only at 320MHz (not 333MHz) due to chipset limitation.
•The following FSB/DDR ratios are not supported: 400/333, 400/400, 533/400.
•FSB/DDR setting 800/333 is recognized as FSB/DDR 800/320.
