SKU CH-3VDH-M41DE

A 16 GB DDR4 module running at 2133 MHz with CL15 ECC registered operation on a 288-pin DIMM

  • 16 GB DDR4 memory expands system capacity
  • 2133 MHz CL15 timing supports responsive data access
  • ECC registered design protects data integrity
  • 288-pin DIMM fits compatible server slots

IBM 47J0253 16 GB DDR4 DIMM

This 16 GB DDR4 module operates at 2133 MHz with CL15 latency and ECC registered dual-rank organisation. It uses a standard 288-pin form factor for compatible server and workstation platforms. The part number is 47J0253.

ECC registered requirement

This module requires a motherboard that supports ECC registered DDR4 memory; it will not function in consumer boards limited to unbuffered non-ECC DIMMs. Builders needing unbuffered memory or a different capacity should select an alternative part.

Questions about this item

What does the 2133 MHz rating mean once this module is installed in a server?

The module will operate at up to 2133 million transfers per second when the platform supports that speed, otherwise it will down-clock to the highest rate the memory controller allows.

How does the DDR4 interface limit the usable bandwidth of this 16 GB stick?

The DDR4 interface caps the theoretical peak at the PC4-17000 rate, so sustained throughput cannot exceed that ceiling regardless of workload.
