32GB DDR5 ECC RDIMM for Servers

This 32GB DDR5 5200 module is built for workstations and servers that require registered ECC memory. It operates at 1.1V with a CL42 latency and a 2Rx4 rank configuration. The 288-pin RDIMM form factor fits compatible server platforms only.

Suits registered ECC platforms only

It suits administrators upgrading compatible workstations, NAS systems or network switches that explicitly support DDR5 registered ECC DIMMs. Builders using standard desktop motherboards or consumer laptops cannot use this module. Systems requiring load-reduced or unbuffered memory should look elsewhere.

Registered ECC is the deciding spec

The module is a registered ECC DDR5 RDIMM, so the motherboard must support registered error-correcting memory. Unbuffered or load-reduced slots will not accept it. Verify the platform documentation before purchase.

Questions about this item

What DDR5 speed and CAS latency does this 32 GB module run at?

It operates at 5200 MT/s (PC5-41600) with a CAS latency of CL42.

What physical slot and pin count does this RDIMM require?

It fits a 288-pin DDR5 RDIMM slot on a workstation or server motherboard.

How is this ECC registered DIMM installed, and what common mistake should be avoided?

Align the notch with the slot key, press straight down until the latches click, and do not mix it with unbuffered or load-reduced memory.
