OWC 16GB DDR4 ECC RDIMM

This OWC module delivers 16GB of DDR4 2666 ECC registered memory built for Lenovo ThinkAgile servers. It runs at 1.2V with CL19 latency and uses a 288-pin 2Rx8 layout. The part replaces Lenovo numbers 01AG618, 4X70P98202 and 7X77A01303. It is validated for HX1320, HX1321, HX2320, HX3320 and HX3520-G systems.

Who this suits

Administrators expanding Xeon SP Gen 1 ThinkAgile clusters will find a direct fit. Buyers who need unbuffered desktop RAM, non-ECC modules or capacities beyond 16GB per slot should look elsewhere. This memory cannot mix with unbuffered DIMMs and will not work in consumer motherboards.

Installation notes

The 288-pin RDIMM seats in standard DDR4 server slots; alignment notches prevent reversed insertion. Common issues include mixing registered and unbuffered sticks, populating slots in the wrong order for the platform or skipping a firmware update that enables full 2666 speed.

Soalan tentang produk ini

Do I need a Lenovo ThinkAgile server with Xeon SP Gen 1 processors for this 288-pin DDR4 2666 ECC RDIMM to work?

Yes, this module is validated for Lenovo ThinkAgile HX1320, HX1321, HX2320, HX3320 and HX3520-G systems built on Xeon SP Gen 1 platforms.

Can I keep my existing 2133MHz or 2400MHz DDR4 ECC registered modules and add this 2666MHz CL19 stick?

The module is backward compatible with 2133MHz and 2400MHz speeds, but it cannot be mixed with unbuffered memory; all populated slots must use registered ECC DIMMs.

How do I confirm the 16GB 2Rx8 module is recognised at 2666MHz with ECC active after installation?

Check the system BIOS or UEFI memory information screen — it should show 16GB, 2666 MT/s, CL19, 1.2V and ECC registered status for the new DIMM.
