Server ECC RDIMM for Lenovo ThinkServer

This 32GB DDR4 2133MHz CL15 registered DIMM is built for Lenovo ThinkServer RD350, RD450, RD550, RD650 and TD350 systems running E5-2600 v3 processors. It targets administrators who need to expand memory capacity in compatible rack or tower servers.

Registered ECC with 2Rx4 organisation

The module uses 288-pin DDR4 ECC registered technology at 1.2V with a 2Rx4 rank structure. This specification decides compatibility; it will not work in standard desktop motherboards and cannot be mixed with unbuffered memory.

Simple DIMM installation with one restriction

Installation follows standard DIMM slot procedures for the listed ThinkServer models. The critical error is attempting to use this registered ECC module in a consumer desktop or mixing it with unbuffered DIMMs, which prevents the system from booting.

Questions about this item

What does the 2133 MHz speed mean once the module is installed in a ThinkServer?

The module runs at DDR4-2133 with CL15 timing, delivering PC4-17000 bandwidth for the E5-2600 v3 memory controller.

How does the registered ECC interface affect what the module can do in practice?

Registered ECC adds a register and error-correction logic, so the module works only in server or workstation boards that support registered memory and cannot be mixed with unbuffered DIMMs.

What physical slot and clearance does the 288-pin RDIMM need to fit in the RD350, RD450, RD550, RD650 or TD350?

It requires a standard 288-pin DDR4 DIMM slot; the module has no heat spreader, so it fits in the factory memory bays of those ThinkServer models.
