Server Memory Kit

This OWC kit provides 32GB of DDR5 ECC Registered memory in a matched pair of 16GB modules. It is built for the Dell PowerEdge R760xd2 server and similar workstation or NAS platforms that require registered DIMMs with error correction.

Installation Notes

Each module uses the standard 288-pin DDR5 RDIMM form factor and operates at 1.1V with CL40 latency at 4800MHz. The sticks have no heat spreader, so they fit tight server slots, but registered ECC memory cannot be mixed with unbuffered or load-reduced modules and will not work in standard desktop boards.

Compatibility Check

Verify that your system specifically supports DDR5 4800 registered ECC RDIMMs and that the memory controller accepts 1Rx8 organisation. Confirm the server has free 288-pin slots and that the BIOS is current enough for PC5-38400 speeds before ordering.
