Lenovo Server DDR4 RDIMM

This 32 GB DDR4 2933 MHz ECC registered DIMM is built for Lenovo ThinkSystem servers that require 1.2 V PC4-23400 memory. It targets administrators upgrading Intel-based platforms where error correction and registered signalling are mandatory for stability.

2Rx4 rank configuration

The module uses a dual-rank 2Rx4 organisation with CL21 latency, which determines whether the server’s memory controller can populate the slot at full speed. Systems that expect a different rank structure or latency will not post with this part installed.

288-pin registered slot

Installation requires an available 288-pin DDR4 RDIMM socket on a compatible Lenovo motherboard; the registered buffer adds electrical load the chipset must support. No heat spreader is fitted, so airflow across the module must come from the chassis fans already present.

Questions about this item

What does the 2933MHz speed mean once the module is installed in a server?

The module runs at DDR4 2933MHz, delivering PC4-23400 bandwidth when the server’s memory controller operates at that frequency.

How does the 288-pin RDIMM interface limit what the module can do?

The 288-pin registered DIMM slot accepts only DDR4 RDIMMs; it cannot take unbuffered UDIMMs or any DDR5 modules.

What physical space and power does the 32GB 2Rx4 stick need to fit and run?

It needs a standard 288-pin DDR4 RDIMM slot and 1.20V supply; the module has no heat spreader, so it fits low-profile bays.
