Server ECC RDIMM for IBM-Lenovo

This 16GB DDR4 2133 module is a registered ECC DIMM built for server and workstation systems that require error-correcting memory. It replaces a long list of IBM-Lenovo part numbers including 00FM012, 00NU400 and 4X70F28590. Buyers who need non-ECC unbuffered memory for a desktop platform cannot use this module.

Sustained load behaviour

Registered buffering and ECC circuitry keep data integrity intact during continuous workloads such as virtualisation, database serving or scientific compute. The CL15 latency at 1.20V delivers stable throughput without the voltage overhead of higher-speed bins. Systems that demand maximum single-thread frequency over data protection will not benefit from this architecture.

Build quality and connectivity

Major-brand chips on a 288-pin PCB are tested to a strict quality standard before shipping. The registered design adds a buffer between the memory controller and the DRAM, reducing electrical load on the motherboard. Platforms that lack RDIMM support in the BIOS or chipset will not post with this module installed.

Questions about this item

How much heat and power does the 1.20V 2133MHz RDIMM add when running continuously?

The module operates at standard DDR4 1.20V voltage, keeping power draw and thermal output low during all-day server workloads.

What must my system already provide for this 288-pin ECC RDIMM to function?

A server or workstation motherboard with DDR4 RDIMM slots, registered DIMM support, and ECC capability is required.

Can I mix this 2Rx4 CL15 module with existing 2133MHz RDIMMs of different rank or latency?

Mixing ranks or CAS latencies at the same 2133MHz speed is possible but not guaranteed; matching specifications ensures stability.
