SKU CH-RKSM-V1HDJ

32 GB DDR4-2133 ECC server memory with quad-rank design for high-density workloads

  • 32 GB capacity supports large virtualised workloads
  • DDR4-2133 speed delivers 17000 MB/s peak bandwidth
  • 4Rx4 organisation increases density per DIMM slot
  • ECC protection corrects single-bit errors automatically

32 GB DDR4-2133 ECC server memory

This HPE module delivers 32 GB of DDR4-2133 ECC memory in a single DIMM. The 4RX4 organisation and PC4-17000 rating suit multi-socket servers that require registered error-correcting modules. It is aimed at administrators expanding capacity in compatible HPE platforms.

Replaces lower-capacity DDR4 ECC DIMMs

The jump is worth it when the server has free slots and the workload needs more addressable memory per channel. It is not for systems that only accept non-ECC UDIMMs or that require speeds above 2133 MT/s.
