  • ECC protection prevents data corruption in critical workloads
  • Registered signal processing improves stability for dense server configurations
  • DDR5 4800 MT/s delivers high bandwidth for demanding applications
  • Single-rank 1Rx8 organisation enables efficient memory channel utilisation
  • Low 1.10 V operation reduces power draw per module

What this module is and who uses it

This 16 GB DDR5 module is built for server platforms that require registered memory with ECC protection. It runs at 4800 MT/s with a CL40 latency and operates at 1.10 V. The single-rank 1Rx8 design fits standard 288-pin DIMM slots in compatible enterprise systems.

Who it suits and who should look elsewhere

Ideal for administrators upgrading or populating servers that specify registered DDR5 with error correction. Not suitable for desktop boards that only accept unbuffered non-ECC memory. Builders needing higher capacities per slot or lower latency timings should consider other modules.

The specification that decides fit

The registered signal processing combined with ECC is the decisive factor; the module will only function in systems designed for registered DDR5 DIMMs. Verify the motherboard qualification list before purchase.

Questions about this item

Should I choose the single 16GB module or look for a 2-module kit?

This listing is a single 16GB DIMM. For dual-channel operation on a typical server board you would need two identical modules, so order a second KSM48R40BS8-16MD if your platform requires paired population.

What does the DDR5-4800 rating deliver once the module is installed?

The module runs at 4800 MT/s with CL40 latency and 1.10 V, providing the standard JEDEC DDR5-4800 bandwidth of PC5-38400 for registered ECC workloads.

How does the 288-pin registered DDR5 interface affect compatibility and speed limits?

The 288-pin registered DDR5 DIMM fits server boards wired for DDR5 RDIMMs; the registered buffer and ECC function are required by those platforms, and the module operates at the rated 4800 MT/s without overclocking.
