Sockets: 18 Sockets (6 Banks of 3) maximum using RDIMMs 12 Sockets (4 Banks of 3) maximum using UDIMMs or QR RDIMMs
Compatible with:
IBM System x3650 M3 7945
Our DDR3-1333 modules automatically clock down to 1066MHz and 800MHz depending on which Intel Xeon model is installed and how many module Banks are populated.
Due to chipset limitations, 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. System only supports (6) Quad Rank DIMMs per CPU or (12) Quad Rank DIMMs with two CPUs.
4GB DDR3-1333 Reg ECC modules come in two versions: 313/4G using x4 and 3138/4G using x8 DRAM. The two parts may be installed in the same system but not within the same memory bank. Use like modules for dual and triple channel operation.
