  • 10 V operation reduces power draw

16GB DDR5-4800 Registered DIMM

This 16 GB DDR5 module runs at 4800 MHz with CL40 latency and 1.10 V operation. It uses a 288-pin DIMM form factor and includes on-die ECC with registered signal processing. The single-rank design supports Intel XMP 2.0 profiles for compatible platforms.

Server and workstation builds

Suited for systems that require registered memory with error correction, such as multi-socket servers or ECC-dependent workloads. Not suited for consumer desktop boards that accept only unbuffered non-ECC modules or that lack registered DIMM support.

16 GB single-module capacity

Provides 16 GB per slot, allowing higher total memory when multiple DIMMs are populated on a supported motherboard. Headroom depends on the platform's maximum DIMM count and memory controller limits; single-rank organisation helps signal integrity at higher population densities.

Questions about this item

Does this module need a server motherboard with registered DDR5 support and a 288-pin DIMM slot?

Yes, the KSM48R40BS8-16HA is a registered DDR5 DIMM with 288 pins and requires a compatible server platform that supports registered memory at 1.10 V.

Can I mix this single-rank CL40 module with existing dual-rank DDR5-4800 sticks?

Mixing ranks is possible on many server boards, but the system will run all modules at the lowest common speed and latency; check your motherboard manual for qualified population rules.

How do I confirm the module runs at DDR5-4800 CL40 after installation?

Enter the BIOS or use a tool like CPU-Z to verify the memory reports 4800 MT/s, CL40 timings, 1.10 V, and registered ECC operation.
