Capacity and purpose

This 4GB DDR4 ECC registered DIMM adds a single memory module to IBM-Lenovo servers that require the 46W0784, 4X70F28588 or 4X70G78060 part numbers. It suits administrators who need a modest capacity increase for virtualisation hosts or database nodes. Buyers who want more storage or non-ECC memory for desktop boards should look elsewhere.

Sustained operation

Registered buffering and ECC protect data integrity during continuous workloads such as batch processing or long-running compute jobs. The CL15 timing at 2133 MHz and standard 1.20 V voltage deliver stable throughput without excessive heat buildup. Systems that demand higher frequencies or lower latencies will not reach those targets with this module.

Build and connectors

The 288-pin DIMM uses major-brand chips on a registered PCB, ensuring reliable seating in server memory slots. Its single-rank 1Rx8 organisation leaves additional channels open for future expansion. Installers must verify the platform's qualified-vendor list, as unlisted motherboards may not initialise the module.

Domande su questo articolo

How much heat and power does the 1.20 V DDR4 2133 RDIMM draw when the server runs all day?

At the standard 1.20 V DDR4 voltage this 4 GB registered module draws minimal power and produces little extra heat, so it fits normal server cooling without special airflow changes.

What must my system already have to accept this 288-pin ECC RDIMM?

A server or workstation motherboard with DDR4 RDIMM slots that supports ECC registered memory and can run at 2133 MHz PC4-17000 CL15.

Will this 1Rx8 module work alongside older 2Rx4 or 2Rx8 DDR4 RDIMMs I keep in the same chassis?

Yes, provided the platform allows mixed-rank populations; the 1Rx8 organisation is compatible with common dual-rank DDR4 RDIMMs when the memory controller permits it.
