Intel - SR1690WB Server System

GLACIER ISLAND

Kingston offers "K3" kit part numbers for Triple Channel mode and "K2" kit part numbers for Dual Channel mode. Kit part numbers consist of two or three Single Rank, Dual Rank, or Quad Rank modules.
Kingston's DDR3-1600 modules automatically clock down to 1333MHz, 1066MHz, and 800MHz depending on which Intel Xeon model is installed and how many module banks are populated. Please refer to the system manual for proper installation of DIMMs for Single, Dual, and Triple Channel configurations.
Due to chipset limitations, Kingston's DDR3 Quad Rank memory is limited to operate at a maximum of 1066Mhz. When two Quad Rank modules are installed per bank, the processor will automatically clock them down to 800MHz.

Mixing x4 and x8 modules is allowed, however not within the same bank.
This system supports either Registered ECC or Unbuffered ECC memory. Mixing Registered ECC and Unbuffered ECC modules is not supported within this system.
