HP 805351-B21 32 GB DDR4 ECC DIMM accessory

SKU CH-4NQ5-6SWPA

A 32 GB DDR4 ECC DIMM module running at 2133 MHz for compatible HP servers

  • High-capacity 32 GB module supports demanding workloads
  • ECC protection detects and corrects data errors
  • DDR4-2133 speed delivers responsive system performance
  • Single DIMM simplifies upgrade planning
  • 288-pin form factor fits compatible server boards

HP 32 GB DDR4 ECC DIMM memory module

This HP 805351-B21 module provides 32 GB of DDR4 SDRAM in a single 288-pin DIMM. It operates at a bus speed rated PC4-17000 (DDR4-2133) and includes ECC error correction. The part is listed as new condition and carries UPC 810766027643 for identification.

Server builders needing registered ECC memory

The module is designed for platforms that require registered DDR4 ECC DIMMs and accept a single 32 GB stick at DDR4-2133 speed. It will not suit laptops or consumer desktops that use unbuffered non-ECC SO-DIMMs. Buyers who need unbuffered memory or a different form factor should look elsewhere.

Registered DDR4-2133 ECC DIMM with 32 GB capacity

The registered ECC design combined with a 32 GB density at DDR4-2133 determines whether this DIMM matches the server or workstation memory requirements. Verify that the target system supports registered modules and this exact speed before purchasing.

Questions about this item

How do I install the 288-pin DDR4 DIMM and which orientation mistake should I avoid?

Align the notch on the module with the key in the slot, press straight down until both side clips click, and do not force it backwards — the offset notch prevents reverse insertion.

What maintenance or replacement will the 32 GB ECC module need over time?

No scheduled maintenance is required; if a memory error occurs the module itself would be replaced, and dust can be cleared with compressed air during routine system cleaning.

At what sustained workload does the DDR4-2133 speed become the limiting factor?

The PC4-17000 bus caps bandwidth at 17 GB/s per module, so continuous memory-intensive tasks such as large dataset processing will hit that throughput ceiling first.
