Server memory upgrade

This 128GB DDR4 3200 CL22 4Rx4 288-pin 1.2V ECC Load Reduced LRDIMM module is built for Dell PowerEdge MX750c R650 R750 servers. It delivers high-density registered memory with error correction for demanding workloads.

Suits server builds only

It fits administrators expanding memory in the listed PowerEdge models or replacing failed modules in compatible NAS and workstation platforms. Builders of standard desktops or consumer laptops cannot use this LRDIMM type.

Simple slot installation

The module seats in a standard 288-pin DDR4 DIMM slot without tools. Mixing with unbuffered or standard registered ECC DIMMs will prevent boot, so populate identical LRDIMM ranks per channel.

Questions about this item

Which Dell PowerEdge servers must I already own for this 288-pin 4Rx4 LRDIMM to be compatible?

This module is validated for Dell PowerEdge MX750c, R650 and R750 systems. It will not work in standard desktops or other server models.

Can I mix this 3200 MHz CL22 LRDIMM with existing 2666 MHz registered ECC DIMMs in the same server?

No. Load-reduced ECC memory cannot be mixed with unbuffered or registered ECC modules. All slots must use identical LRDIMM specifications.

How do I confirm the module is running at 3200 MHz with ECC active after installation?

Check the BIOS memory information or OS hardware report. It should show 3200 MT/s speed, CL22 latency, 1.2 V voltage and ECC enabled status.
