256GB DDR5 4800 ECC RDIMM Kit

This OWC memory kit provides 256GB of DDR5 4800 PC5-38400 CL40 registered ECC RDIMM capacity across two 128GB modules. It uses 288-pin 4Rx4 DDR5 technology operating at 1.1V. The kit is validated for Dell Precision Workstation 5860, 5860XL, 7960, 7960XL towers and the 7960 rack model.

Workstation and Server Upgrades Only

This registered ECC memory suits administrators expanding Dell Precision workstations or compatible servers requiring error-correcting registered DIMMs. It will not work in standard desktop computers that accept only unbuffered non-ECC modules. Builders needing unbuffered memory or load-reduced DIMMs must select a different memory type.

Registered ECC DDR5 Form Factor

The modules are 288-pin DDR5 registered ECC RDIMMs with a 4Rx4 organisation. This specific form factor and buffering type determines physical and electrical compatibility with the memory controller. Verify the target system requires registered ECC RDIMMs before purchase.

Questions sur cet article

How much power does the 1.1 V DDR5 4800 RDIMM kit draw when the workstation runs all day?

Each module operates at 1.1 V, the standard DDR5 voltage, so total power scales with the 256 GB capacity and the 4800 MT/s data rate rather than any higher voltage.

What must the system already provide for these 288-pin ECC registered DIMMs to function?

A Dell Precision 5860, 5860XL, 7960 or 7960XL workstation with DDR5 RDIMM slots and a CPU memory controller that supports registered ECC at 4800 MT/s.

Can the 4Rx4 CL40 modules share channels with older DDR5 RDIMMs of different rank or speed?

They will run at the lowest common speed and the platform must support mixed 4Rx4 ranks; JEDEC compliance allows it, but the workstation BIOS determines the final configuration.
