NEMIX RAM 16GB DDR5 4800 ECC RDIMM

This 16GB DDR5 module runs at 4800MHz with CL40 latency and 1.1V operation. It uses a 1Rx8 registered ECC design on a 288-pin RDIMM form factor built with Samsung components. The memory is intended for server and workstation platforms that require registered error-correcting modules.

Suited for registered DDR5 server slots needing ECC

Buyers who need unbuffered non-ECC UDIMMs for consumer desktops or laptops cannot use this module. Systems that do not support registered memory or that lack DDR5 RDIMM slots will not accept it. The single 16GB stick also limits total capacity unless additional identical modules are installed.

1Rx8 registered ECC architecture decides

The registered buffer and on-die ECC require a motherboard chipset and BIOS that explicitly support RDIMM operation. Without that support the module will not post or will run without error correction. Verify the platform documentation for DDR5 RDIMM qualification before purchase.

Questions about this item

What comes in the box with the NEMIX RAM 16GB DDR5 4800 CL40 ECC RDIMM?

The package contains one 16GB 288-pin DDR5 RDIMM module rated at 4800 MT/s with CL40 latency and 1.1V operation. No extra cables or brackets are included.

Should I choose the 1Rx8 registered ECC version or look for a different rank configuration?

This module is a single-rank 1Rx8 registered ECC DIMM; select it when your server or workstation requires registered error-correcting memory in a 16GB capacity.

What does the 4800 MT/s rating mean once the module is installed in a compatible system?

The memory will run at up to 4800 MT/s (PC5-38400) with CL40 timings at 1.1V, delivering the rated bandwidth and error-correction for supported DDR5 server platforms.
