OWC 32GB DDR5 4800 ECC RDIMM Kit

This kit provides two 16GB DDR5 4800 CL40 registered ECC modules totalling 32GB. It is built for Dell PowerEdge R660XS and R760XS servers that require registered memory with error correction. The modules run at 1.1V and conform to JEDEC PC5-38400 specifications.

Registered ECC for Compatible PowerEdge Servers

The memory suits administrators upgrading or repairing the listed Dell PowerEdge models where registered ECC RDIMMs are mandatory. It will not work in standard desktop PCs or workstations that accept only unbuffered non-ECC DIMMs. Buyers needing load-reduced ECC or unbuffered memory must select a different module type.

32GB Capacity at DDR5 4800 Speed

The 32GB kit handles typical virtualisation workloads, database buffers and multi-threaded server tasks within the memory slots of the supported platforms. Performance headroom ends when the server's maximum registered DIMM population or total memory limit is reached, which varies by chassis configuration.

Questions about this item

What server models must I already own for this 288-pin DDR5 ECC Registered RDIMM kit to work?

This kit is validated for Dell PowerEdge R660XS and R760XS servers; it will not function in standard desktops or other platforms.

Can I add these 1Rx8 CL40 modules alongside existing DDR5 ECC Registered memory in my R660XS or R760XS?

Yes, provided the installed memory is also DDR5 ECC Registered RDIMM at 4800 MT/s; mixing with unbuffered or load-reduced DIMMs is not supported.

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

Check the BIOS memory information or the iDRAC inventory; both will report 4800 MT/s speed, CL40 timings and ECC Registered status for each 16 GB module.
