OWC 512GB (8x64GB) DDR5 4800 CL40 2Rx4 288-pin 1.1V ECC Registered RDIMM memory upgrade

OWC 512GB DDR5 ECC Registered Kit

This kit delivers 512GB of DDR5 4800 memory across eight 64GB registered DIMMs. It is built for Dell PowerEdge R760xd2 servers and workstations that require ECC error correction and registered signal buffering. The modules operate at 1.1V with CL40 latency and conform to the PC5-38400 standard. They will not function in standard desktop computers or alongside unbuffered or load-reduced memory types.

Sustained Load Behaviour

Registered ECC modules maintain data integrity during continuous server workloads such as virtualisation, database hosting and large-scale file serving. The on-board register reduces electrical load on the memory controller, allowing all eight DIMMs to run stably at the rated 4800 speed under prolonged utilisation. Error-correcting code detects and corrects single-bit errors in real time, preventing silent data corruption during extended operations.

Pre-Installation Checklist

Verify that your system is a Dell PowerEdge R760xd2 and that the motherboard supports 288-pin DDR5 registered DIMMs with 2Rx4 organisation. Confirm the server currently uses registered ECC memory; mixing with unbuffered or load-reduced modules is not supported. Ensure all eight memory slots designated for this configuration are available and that the BIOS is updated to recognise the full 512GB capacity.
