32GB DDR5 4800 ECC RDIMM

This 32GB DDR5 module runs at 4800 MT/s with CL40 latency and operates at 1.1V. It is an ECC registered DIMM built for workstations and servers that require error correction and signal buffering.

Suits registered ECC platforms only

It will not work in standard desktop computers or any system that expects unbuffered or load-reduced memory. Builders who need consumer DDR5 or non-ECC modules must choose a different product.

Single 288-pin 2Rx8 module

The stick plugs directly into a compatible 288-pin DDR5 slot and draws 1.1V. It frees the builder from mixing ranks or speeds, provided the platform supports registered ECC memory.

Questions about this item

What type of motherboard slot is required for this 288-pin DDR5 RDIMM?

A server or workstation motherboard with a DDR5 RDIMM slot that supports ECC registered memory. Standard desktop boards with unbuffered slots will not accept it.

Can this CL40 2Rx8 module be mixed with existing ECC unbuffered or load-reduced DIMMs?

No. The module is ECC registered and must not be mixed with unbuffered or load-reduced memory; all DIMMs in the system should be identical registered ECC type.

How can I verify the module is running at DDR5 4800 with CL40 timings after installation?

Check the BIOS memory information or use a system utility such as CPU-Z to confirm the reported speed of 4800 MT/s and CAS latency of 40.
