Dell PowerEdge R960 Memory Kit

This 512GB kit contains four 128GB DDR5 registered DIMMs built for the Dell PowerEdge R960 rack server. It targets IT teams upgrading memory capacity in mission-critical enterprise environments. ECC and registered buffering protect data integrity under heavy workloads.

Capacity and Headroom

The 512GB total provides substantial headroom for virtualization, large databases and in-memory analytics. Four 4Rx4 modules fill four slots at DDR5 4800 speed. Workloads exceeding 512GB or requiring higher frequencies will need additional modules or a different platform.

CL40 Latency at 1.10V

CAS latency 40 at 1.10V defines the timing and power envelope for this registered DDR5 kit. Systems that require lower latency or different voltage settings cannot use this configuration. Compatibility is validated for the specified Dell server model.

Questions about this item

Will these 4Rx4 DDR5 4800 modules work with the existing 2Rx4 DDR5 4800 sticks already in my PowerEdge R960?

The kit uses 4Rx4 organisation; mixing different rank configurations in the same channel can prevent the server from posting, so populate all slots with identical 4Rx4 modules or follow Dell's approved memory population rules for the R960.

How do I verify the 512GB kit is running at CL40 1.10V after installation?

Enter the system BIOS or iDRAC interface and confirm the memory speed shows 4800 MT/s, CAS latency 40 and voltage 1.10V; ECC status should read active for each of the four 128GB RDIMMs.

Does the MR38400-744K4 box include only the four 288-pin RDIMMs or are any tools or cables supplied?

The package contains the four 128GB DDR5 ECC registered RDIMMs only; no installation tools, cables or additional hardware are included.
