Comments:

Only Opterons 246 and higher support DDR400 memory.
Using DDR400, this system supports a maximum SIX ranks of memory per CPU.
Six ranks is achieved with two Dual Rank DIMMs plus two Single Rank DIMMs.
If 4GB is installed, the recognized memory may be reduced to 3.5GB or less (depending on system configuration and memory allocation).
When mixing ECC (X72) and non-ECC (X64) modules, the system will not perform the ECC function.
