Comments:
Modules must be ordered and installed in pairs for Dual Channel Mode, which can provide a small performance increase over single channel configurations.

Kingston offers "K2" Kit part numbers for Dual Channel mode.

Mixing DDR2-533 Registered DIMMs with DDR2-667 Registered with Parity DIMMs is not recommended.

Only systems with AMD's Opteron Socket(s) F 45-nm CPU can use the DDR2-800 part numbers.

Mixing x4 and x8 modules is allowed, however not within the same bank.

To achieve 64GB using DDR2-667 (32GB per processor bank), 4GB Single Rank modules must be installed.

There is a limit of eight memory ranks per processor bank at this speed, using either FOUR Dual Rank modules, or EIGHT Single Rank modules
