128GB DDR4 2666 ECC Registered RDIMM

This single 128GB DDR4 2666 PC4-21300 CL19 8Rx4 288-pin 1.2V ECC Registered RDIMM is built for servers, workstations and NAS systems that require registered memory with error correction. It will not work in standard desktop computers and cannot be mixed with unbuffered or load-reduced DIMMs.

Check registered ECC support and rank limits

Verify that your platform accepts 288-pin DDR4 Registered ECC modules and supports 8Rx4 rank configurations before ordering. The memory is backward compatible with 2133MHz and 2400MHz bus speeds, so it will down-clock automatically if the system runs at those lower frequencies.

Replaces Cisco UCS-MR-128G8RS-H

This module directly replaces the Cisco UCS-MR-128G8RS-H, Dataram DRC2666TR/128GB and DRV2666R/128GB, and S26361-F4026-E728 part numbers. The upgrade is worth it when you need maximum capacity per slot in a compatible registered ECC platform and want a JEDEC-standard, RoHS-compliant alternative with a limited lifetime warranty.

商品問答

Does the 128GB 288-pin ECC Registered RDIMM arrive as a single module, or must additional sticks be purchased separately?

The upgrade consists of one 128GB DDR4 2666 PC4-21300 CL19 8Rx4 288-pin 1.2V ECC Registered DIMM; no extra modules are required for this capacity.

Should I choose the 2666MHz CL19 version or a lower-speed alternative for my server?

This module runs at 2666MHz CL19 and is backward compatible with 2133MHz and 2400MHz systems, so it covers all three speeds in one part.

What does the PC4-21300 rating mean once the DIMM is installed in a registered-memory server?

PC4-21300 indicates a peak transfer rate of 21300 MB/s at 2666MHz with CL19 latency, delivering that bandwidth when the platform supports registered ECC DDR4.
