32GB DDR5 4800 RDIMM ECC Server Module

This 32GB DDR5 module runs at 4800 MT/s with CL40 latency and 1.1V operation. It uses a 1Rx4 registered ECC design on a 288-pin form factor built for server motherboards requiring registered memory.

Works With ASRock Rack GENOA2D24G-2L+ Only

Suitable for administrators upgrading that specific ASRock Rack board where the manual approves this exact rank, voltage and timing. Not for desktop PCs, laptops or any system needing unbuffered UDIMMs or SODIMMs.

1Rx4 Registered ECC Rank Decides Fit

The single-rank 1Rx4 registered ECC organisation is the specification the memory controller expects; a different rank count or unbuffered type will not be recognised at full capacity or speed.

Questions about this item

Does this 32 GB DDR5-4800 CL40 RDIMM require a motherboard that supports registered ECC memory?

Yes, this module is a 288-pin DDR5 RDIMM with registered ECC architecture. It needs a server motherboard such as the ASRock Rack GENOA2D24G-2L+ that accepts registered ECC DIMMs and runs at 1.1 V.

Can I install this 1Rx4 32 GB DDR5-4800 RDIMM alongside other registered ECC modules in the same server?

The module is a single-rank 1Rx4 part rated at CL40 and 1.1 V. Mixing works only if every installed DIMM matches the same registered ECC type, voltage, speed and rank configuration approved by the motherboard manual.

How do I confirm the system sees the full 32 GB at 4800 MT/s after installation?

Enter the BIOS or UEFI and check the memory information screen. It should report 32 GB capacity, DDR5-4800 (PC5-38400) speed, CL40 timings and ECC active for the installed slot.
