Dell Precision 7960XL Rack Memory Kit

This OWC kit delivers 128 GB of DDR5 ECC registered memory in two 64 GB modules. It is built for the Dell Precision 7960XL Rack workstation and runs at 4800 MT/s with CL40 latency at 1.1 V.

Suited for ECC Registered Workstation Upgrades

The modules are 288-pin DDR5 RDIMMs with 2Rx4 organisation and ECC error correction. They will not work in standard desktop boards, nor can they be mixed with unbuffered or load-reduced ECC memory types.

Fits 7960XL Rack DIMM Slots Directly

Installation uses the workstation's existing registered DIMM sockets and 1.1 V power rail. The kit adds capacity without requiring voltage changes, leaving other expansion slots and cooling resources untouched.

Questions about this item

Does the Dell Precision 7960XL Rack need to support DDR5 ECC Registered RDIMMs for this 128GB kit to work?

Yes, the workstation must accept DDR5 4800 CL40 2Rx4 288-pin 1.1V ECC Registered RDIMMs; this kit is built specifically for that platform.

Can I keep my existing DDR5 4800 ECC Registered modules and add this 2x64GB kit alongside them?

You can add this kit if the system has free 288-pin slots and all modules are DDR5 4800 ECC Registered; mixing with unbuffered or load-reduced DIMMs is not supported.

How do I confirm the kit is running at 4800 CL40 with ECC active after installation?

Check the BIOS or OS memory report for 4800 MT/s speed, CL40 latency, 128GB total capacity and ECC Registered status.
