Server Memory Kit

This 512GB kit contains eight 64GB DDR5 4800 ECC registered RDIMMs designed for Dell PowerEdge R760xa R860 and R960 servers. It targets administrators who need maximum registered ECC capacity in those specific platforms.

Compatibility Check

Verify that your server model is one of the three listed PowerEdge systems before ordering. This registered ECC memory will not work in standard desktops or workstations and must not be mixed with unbuffered or load-reduced modules.

Build and Connectors

Modules use the 288-pin DDR5 form factor without heat spreaders and operate at 1.1V. The registered design adds a buffer for signal integrity in dense server configurations while the ECC function corrects single-bit errors during operation.

Questions about this item

What comes in the box and do I need anything else to install it?

The kit contains eight 64 GB DDR5 4800 CL40 2Rx4 ECC registered RDIMMs for a total of 512 GB. No extra parts are required; the modules slot directly into the 288-pin DIMM sockets of a compatible PowerEdge server.

How do I decide between the available capacities for this server?

This kit is a single 512 GB configuration (8 × 64 GB). Choose it when the workload needs the maximum supported capacity per socket; smaller kits would use fewer or lower-density modules.

What does the 4800 MT/s rating deliver in a PowerEdge R760xa, R860 or R960?

At 4800 MT/s with CL40 latency and 1.1 V operation, the modules run at the standard JEDEC DDR5 speed for these platforms, providing ECC error correction and registered buffering for stable server workloads.
