Dell Precision 7960XL Rack memory upgrade

This 64GB kit contains two 32GB DDR5 4800 CL40 ECC registered RDIMMs built to JEDEC and RoHS standards. The modules run at 1.1V and use a 2Rx8 organisation on a 288-pin form factor. They are designed specifically for the Dell Precision Workstation 7960XL Rack and cannot be mixed with unbuffered or load-reduced memory.

Workstation and server builders needing registered

The kit suits administrators expanding a Dell Precision 7960XL Rack for virtualization, database or render workloads that require error-correcting registered memory. It is not for standard desktop PCs, consumer laptops or any system that accepts only unbuffered non-ECC DIMMs. Buyers who need load-reduced ECC or higher capacities per module should look elsewhere.

Two-slot registered DIMM installation

Each module occupies one 288-pin DDR5 RDIMM slot on the workstation motherboard. The registered buffer reduces electrical load on the memory controller, allowing the 64GB total to operate at the rated 4800 speed without additional cooling hardware. No heat spreader is fitted, so standard chassis airflow is sufficient. The upgrade leaves remaining slots free for future registered ECC expansion.

Questions about this item

What Dell workstation is this 288-pin DDR5 ECC RDIMM kit validated for?

The kit is tested and approved for the Dell Precision Workstation 7960XL Rack.

Can I add these registered modules to a system that already has unbuffered or load-reduced ECC memory installed?

No, registered ECC RDIMMs cannot be mixed with unbuffered or load-reduced ECC memory; the system requires matching registered modules.

After installation, how do I confirm the 64 GB kit is running at the rated 4800 MT/s CL40 with ECC active?

Check the BIOS or UEFI memory information screen; it should report 64 GB at 4800 MT/s, CL40 timings, 1.1 V, and ECC enabled.
