128GB DDR4 ECC RDIMM for ThinkAgile HX

This 128GB DDR4 2933 PC4-23400 CL21 8Rx4 288-pin ECC Registered RDIMM is built for Lenovo ThinkAgile HX servers running second-generation Xeon Scalable processors. It targets administrators expanding memory in HX1320, HX1321, HX2320, HX2321 or HX3320 nodes. The module will not work in standard desktop PCs or alongside unbuffered or load-reduced DIMMs.

Sustained load behaviour

ECC and registered buffering keep data integrity intact during continuous workloads such as virtualisation, databases or high-performance computing. Operation at 1.2V and CL21 latency delivers stable throughput at the rated 2933 MT/s, while backward compatibility allows the module to run at 2133, 2400 or 2666 MT/s if the platform requires it.

Build and mounting

The bare 288-pin RDIMM has no heat spreader, relying on server chassis airflow for cooling. JEDEC and RoHS compliance ensures a warranty-safe upgrade that meets OEM specifications. A single 128GB stick fills one slot, leaving remaining slots free for future expansion without mixing memory types.

Otázky k tomuto produktu

How much power does the 1.2V DDR4 2933 module draw when the server runs continuously?

The module operates at 1.2V, the standard DDR4 voltage for registered ECC DIMMs, keeping power draw low during all-day workloads.

What must the system already have to accept this 288-pin 8Rx4 registered DIMM?

A Lenovo ThinkAgile HX1320, HX1321, HX2320, HX2321 or HX3320 with Xeon SP Gen 2 processors and DDR4 registered DIMM slots.

Will this 2933 MHz CL21 stick work alongside existing 2133, 2400 or 2666 MHz modules in the same ThinkAgile server?

Yes, it is backward compatible with 2133, 2400 and 2666 MHz speeds; all modules will run at the lowest common frequency.
