Dell Precision 7960XL Rack memory upgrade

This OWC module adds 64GB of DDR5 ECC registered memory to a Dell Precision 7960XL Rack workstation. It is built for systems that require registered DIMMs with error correction and will not work in standard desktop computers. The single-module design simplifies capacity expansion without mixing ranks.

Registered ECC DDR5 constraints

Registered ECC DDR5 DIMMs must match the platform's memory controller exactly and cannot be mixed with unbuffered or load-reduced modules. The 288-pin form factor and 1.1V operation are fixed by the DDR5 standard for this class of hardware. Compatibility is limited to systems validated for registered ECC memory.

64GB single-module capacity

A single 64GB 2Rx4 RDIMM delivers the full upgrade in one slot, leaving additional sockets free for future expansion. The CL40 latency at 4800MT/s meets the JEDEC PC5-38400 specification for this workstation. Buyers needing higher total capacity must add further identical registered ECC modules.

Questions about this item

Should I choose the 64GB DDR5 4800 CL40 ECC Registered RDIMM or a lower-capacity module?

This module provides 64GB in a single 288-pin RDIMM; select it when the Dell Precision 7960XL Rack needs maximum capacity per slot.

What does the DDR5 4800 CL40 rating deliver in the Dell Precision 7960XL Rack?

The module runs at 4800 MT/s with CAS latency 40 at 1.1V, giving the workstation JEDEC-standard DDR5 bandwidth and error correction for registered memory workloads.

How does the 288-pin ECC Registered RDIMM interface limit installation in the 7960XL Rack?

The 288-pin registered DIMM fits only DDR5 RDIMM slots; it cannot be mixed with unbuffered or load-reduced modules and requires a platform that supports registered ECC memory.
