8GB DDR4 ECC UDIMM for IBM-Lenovo servers

This 8 GB DDR4 module runs at 2133 MHz with CL15 latency and 1.20 V operation. It is built as an unbuffered ECC UDIMM using a 2Rx8 organisation and major-brand chips. The part replaces IBM-Lenovo numbers 46W0812, 46W0813, 4X70G88316, 4X70G88331 and 4X70K14184. It targets administrators who need validated ECC memory for compatible ThinkSystem or System x platforms.

288-pin DDR4 DIMM fits standard unbuffered ECC slots

The module uses the standard 288-pin DDR4 DIMM form factor and requires a motherboard that supports unbuffered ECC UDIMMs at the PC4-17000 speed grade. It installs directly into an available DIMM slot without registered or load-reduced signalling. Systems that require registered RDIMMs or LRDIMMs cannot use this module, and platforms limited to non-ECC memory will not benefit from the error-correction capability.

Sustained server workloads with ECC protection

Under continuous load the ECC function detects and corrects single-bit errors to maintain data integrity across long-running tasks. The 1.20 V DDR4 standard voltage keeps power draw consistent during extended operation. Modules are tested for reliability before shipping. Buyers who need higher capacities per slot, registered buffering or faster DDR4 speeds should verify their platform specifications before ordering.

Questions about this item

Does the 2Rx8 dual-rank layout limit how many modules I can populate per channel?

Each module is a 2Rx8 DDR4 2133 ECC UDIMM; the maximum modules per channel depends on your server or workstation memory-controller specification, so check the system manual before filling every slot.

What thermal load should I expect from the 1.20 V DDR4 2133 modules during continuous operation?

Standard DDR4 1.20 V ECC UDIMMs run cool under sustained load; adequate chassis airflow is normally sufficient and no extra cooling is required for the memory itself.

Which motherboard feature must already be present for this ECC UDIMM to function?

The board must support DDR4 ECC unbuffered DIMMs at 2133 MHz with a 288-pin slot; without that native ECC UDIMM capability the module will not operate.
