Server memory upgrade

This OWC 128GB DDR4 3200 CL22 ECC Load Reduced DIMM is built for Dell PowerEdge C6525, R6515 and R7515 servers. It delivers 128GB of registered ECC memory in a single 288-pin module running at 1.2V. The 8Rx4 organisation and PC4-25600 rating match the platform specifications.

Not for desktops or mixed configs

This module suits administrators expanding memory in the listed PowerEdge models or building compatible server and workstation systems. It will not work in standard desktop computers and cannot be mixed with unbuffered or standard registered ECC DIMMs. Buyers needing non-ECC memory or consumer form factors should look elsewhere.

Simple slot installation

Installation follows standard DIMM procedure: power down the server, open the chassis, align the notch and press firmly until the ejectors latch. The module is backward compatible with 2133, 2400, 2666 and 2933MHz bus speeds. The most common issue is attempting to combine Load Reduced DIMMs with other ECC types, which the platform does not support.

Questions about this item

Which Dell PowerEdge servers must I already own for this 128GB DDR4 3200 CL22 8Rx4 288-pin 1.2V ECC LRDIMM to be compatible?

This module is validated for Dell PowerEdge C6525, R6515 and R7515 systems only.

How does this LRDIMM behave when installed alongside slower DDR4 modules already in my R6515?

The module is backward compatible with 2133MHz, 2400MHz, 2666MHz and 2933MHz DDR4 speeds and will downclock to match the slowest installed module.

What BIOS indication confirms the 128GB 8Rx4 LRDIMM is running at 3200 CL22 with ECC active?

The system POST or BIOS memory summary should show 128GB per DIMM at 3200 MT/s, CL22 timings and ECC Load Reduced status.
