Only Opterons x46 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.
Each processor installed must have at least one DIMM module populated in either DIMM_0 or DIMM_2 to function properly.
MODULES MUST BE ORDERED AND INSTALLED IN PAIRS for Dual Channel mode. Kingston offers "K2" kit part numbers for Dual Channel mode.
Mixing x4 and x8 modules is allowed, however not within the same bank. If featured, Chipkill technology is supported with x4 modules only.
KVR266X72RC25L/xxx parts are the same as the non "L" except they are low profile.
KRX3200K2/xx parts have a timing of 3-3-3 (AMD approved)
KRX3200AK2/xx parts have a timing of 2.5-3-3
