128GB DDR4 2933MHz ECC RDIMM Server Module

This 128GB registered DIMM operates at DDR4 2933MHz with CL21 latency and 1.20V power. It targets administrators upgrading IBM-Lenovo servers that require the 02JG082, 4ZC7A15138 or 4ZC7A15113 part numbers for memory expansion.

288-Pin Registered Build With 4Rx4 Organisation

The module uses a 288-pin DDR4 DIMM form factor with registered signalling and 4Rx4 rank configuration. Registered buffering reduces electrical load on the memory controller, while the 4Rx4 layout fits the density into a single slot for compatible platforms.

DDR4 2933MHz Interface Limits

The PC4-23400 standard caps peak bandwidth at the rated 2933MT/s transfer rate. Systems that only support lower DDR4 speeds will downclock the module, and platforms requiring unbuffered UDIMMs or different rank counts cannot use this registered 4Rx4 stick.

Questions about this item

What DDR4 standard and speed does this 128GB module run at?

It operates at DDR4 2933 MHz, rated PC4-23400 with a CAS latency of CL21 and standard 1.20V voltage.

What physical slot and pin count does this 288-pin RDIMM require?

The module uses a 288-pin DDR4 DIMM form factor and must be installed in a registered DIMM slot that supports 4Rx4 configuration.

How do I seat this registered ECC module correctly in a server board?

Align the notch with the keyed slot, press firmly until both retaining clips click, and verify the system recognises the full 128GB capacity at 2933 MHz.
