32GB DDR5 4800MHz ECC RDIMM

This 32GB DDR5 4800MHz ECC RDIMM module uses 288-pin registered DIMM technology with a 2Rx8 rank structure. It operates at the standard 1.10V DDR5 voltage and carries a CAS latency of 40. The module is built as a direct replacement for specific Hynix part numbers.

Suited for server and workstation upgrades

This module suits administrators upgrading or repairing servers that require DDR5 4800MHz registered ECC memory in a 32GB density. It is not for desktop boards that only accept unbuffered non-ECC DIMMs, nor for systems limited to lower DDR5 speeds or different pin counts.

Registered ECC with 2Rx8 organisation

The registered ECC design with 2Rx8 organisation is the single specification that determines compatibility. Only platforms whose memory controllers support registered error-correcting modules at this rank configuration will accept the part.

Questions about this item

What speed does DDR5 4800 (PC5-38400) actually run at in a server?

The module operates at 4800 MT/s, delivering PC5-38400 bandwidth when the platform supports DDR5-4800; the memory controller will down-clock if the CPU or chipset specifies a lower maximum.

What physical slot and clearance does this 288-pin RDIMM need?

It fits a standard 288-pin DDR5 DIMM socket; the module has no heat spreader, so it sits at the base JEDEC height and clears most CPU coolers and chassis air baffles.

How do I install this ECC RDIMM and what step is often missed?

Power down, open the chassis, align the notch with the key in the 288-pin slot, press firmly until both retention clips click, then consult the system manual for correct channel population and BIOS memory mapping for registered ECC modules.
