32 GB DDR4 2666 ECC RDIMM for Lenovo servers

This 32 GB registered DDR4 module runs at 2666 MHz with CL19 latency and 1.2 V operation. It uses a 2Rx4 organisation and carries ECC for data integrity in server workloads. The 288-pin RDIMM form factor targets Lenovo systems referencing part number 78P4198.

Verify registered ECC support and slot availability

Confirm the motherboard accepts registered ECC RDIMMs rather than unbuffered or non-ECC memory. Check that a free 288-pin DDR4 slot exists and that the platform qualifies 2666 MHz modules at 1.2 V. Consult the system manual for maximum capacity per slot and population rules.

Replaces lower-capacity or non-ECC DDR4 RDIMMs

Upgrading from smaller registered modules adds capacity for virtualisation and database tasks while retaining ECC protection. The jump is worthwhile when the platform supports 2666 MHz registered memory and the workload benefits from 32 GB per slot. Systems limited to unbuffered memory cannot use this module.

Questions sur cet article

Does the box contain anything besides the single 32 GB DDR4 2666 CL19 2Rx4 ECC RDIMM?

The package includes only the 32 GB (1×32 GB) DDR4 2666 MHz PC4-21300 2Rx4 1.2 V CL19 288-pin ECC RDIMM; no cables, brackets or extra modules are supplied.

How do I decide between this 32 GB module and a smaller capacity for my Lenovo server?

Choose this 32 GB stick when the motherboard supports 2Rx4 registered DIMMs and you need maximum capacity per slot; smaller modules use fewer ranks and may be required if the board limits total rank count.

What does the 2666 MHz rating mean once the DIMM is installed in a compatible Lenovo system?

The module will run at 2666 MT/s with CL19 latency at 1.2 V, delivering PC4-21300 bandwidth while the registered buffer and ECC maintain data integrity under server workloads.
