128GB DDR4-2666 8Rx4 ECC LRDIMM

This 128GB DDR4-2666 registered LRDIMM uses an 8Rx4 organisation and runs at 1.20V with ECC. It is a 288-pin module built with major-brand DRAM and rated PC4-21300. The part is 100% Cisco compatible and matches the UCS-MR-128G8RS-H specification for server memory upgrades.

Server builders needing maximum density per slot

This module suits administrators who want to maximise installed memory in compatible Cisco UCS platforms without replacing hardware. Buyers whose systems cannot address 8Rx4 LRDIMMs or require unbuffered DIMMs should look elsewhere.

8Rx4 rank configuration decides fit

The single specification that determines compatibility is the 8Rx4 rank structure. Only platforms qualified for this rank count and LRDIMM form factor will recognise the full 128GB capacity at DDR4-2666 speed.

Questions about this item

Does my server need 288-pin DDR4 slots to use this 128GB LRDIMM?

Yes, this module uses the standard 288-pin DDR4 form factor and requires a compatible DDR4 slot that supports Load-Reduced DIMMs.

Can I mix this 8Rx4 LRDIMM with existing 4Rx4 RDIMMs in the same system?

Mixing LRDIMMs and RDIMMs is not supported; all slots must use the same registered memory type for the system to operate correctly.

How do I confirm the module is running at 2666 MT/s after installation?

Check the BIOS memory information or use a system utility such as dmidecode to verify the configured speed shows 2666 MT/s.
