256GB ECC Registered DDR5 Kit

This OWC kit delivers 256GB across four 64GB DDR5 4800 CL40 registered DIMMs. It is built for Dell Precision 5860 and 7960 workstations that require ECC registered memory. The modules run at 1.1V and conform to JEDEC PC5-38400 specifications.

Workstation buyers needing maximum capacity

Suits engineers and IT teams expanding Dell Precision 5860 or 7960 towers and racks with registered ECC memory. Not for standard desktop PCs, laptops or consumer motherboards that only accept unbuffered non-ECC DIMMs. Cannot be mixed with unbuffered or load-reduced ECC modules.

Registered ECC DDR5 4800 CL40 specification

The registered ECC DDR5 4800 CL40 design is the single factor that determines compatibility. Only systems listed — Dell Precision 5860, 5860XL, 7960 and 7960XL — support this module type. Verify your workstation requires registered ECC before purchase.

Questions about this item

Can I add this 4x64GB DDR5 4800 CL40 kit alongside existing RDIMMs in my Precision 5860?

The kit provides four registered 2Rx4 modules at 1.1V. Dell Precision 5860 and 7960 platforms require all installed DIMMs to be ECC registered of matching rank and voltage; mixing with unbuffered or load-reduced memory is not supported.

How do I confirm the 256GB kit is running at 4800 MT/s with ECC active after installation?

Enter the system BIOS or UEFI and verify the memory speed reads 4800 MT/s, total capacity shows 256GB, and ECC status is reported as enabled or active for each of the four slots.

What ships in the box and do I need any extra parts to install in a 7960 Tower?

The package contains four 64GB 288-pin DDR5 ECC registered RDIMMs; no heat spreaders, cables or tools are included and none are required for installation in the 7960 Tower.
