HPE P43324-0A1 PC5-38400 DDR5 ECC Memory

P43324-0A1 is the assembly part number for HPE’s 16GB single-rank x8 DDR5-4800 Registered SmartMemory family. It maps to option P43322-B21 and service spare P48499-001. The assembly identity is especially useful during physical server audits because it can be read directly from the installed DIMM even when original option packaging is no longer available.

Audit the Memory That Is Actually Installed

Servers can change during years of upgrades and repairs. Reading P43324-0A1 from the module gives asset teams a current hardware reference rather than relying only on the original build sheet.

Assembly Cross-Reference

• Assembly: P43324-0A1

• Rank: Single Rank x8
• Latency: CAS 40-39-39
• Type: ECC Registered SmartMemory

Keep Three HPE Identities in One Inventory Family

Without cross-referencing, option, spare and assembly numbers can become duplicate stock records. Mapping P43324-0A1 to P48499-001 and P43322-B21 gives purchasing and engineering teams one coherent memory family.

Why Rank and Organisation Matter

Capacity is not the only memory characteristic. Single-rank x8 organisation is part of the documented identity and can help engineers distinguish this DIMM from other 16GB or higher-capacity modules during population planning.

DDR5-4800 Is Not DDR5-5600

The P64705-B21 16GB DDR5-5600 SmartMemory kit belongs to a different speed family. HPE documentation for relevant Gen11 platforms states that 4800 and 5600 memory should not be mixed.

Population and Effective Speed

For the documented 4800 family, HPE notes 4800 MT/s at one DIMM per channel and 4400 MT/s at two DIMMs per channel. The rated module speed therefore needs to be considered with the final population.

New and Refurbished Assembly-Matched Memory

New modules can support compatible builds and planned upgrades. Refurbished P43324-0A1-family memory can be practical for deployed systems already standardised on DDR5-4800.

Build a More Useful Hardware Record

Exact identities for memory, controllers and adapters make future maintenance easier. Related examples include P58543-001 MR408i-o, P26987-001 10Gb adapter and P49751-001 6.4TB SAS SSD.

Source by Assembly Number

Euroland IT Store can help map P43324-0A1 to the related HPE option and spare and source New or Refurbished SmartMemory where available.

Useful across a Long Server Lifecycle

Memory may be upgraded, replaced under warranty or moved between compatible systems over several years. Periodic assembly-level audits help infrastructure teams understand the current population rather than relying on an outdated original specification.

Assembly Labels Can Reveal Past Upgrades

A server purchased with one memory configuration may have received additional DIMMs or service replacements later. Reading assembly labels such as P43324-0A1 helps infrastructure teams discover those changes. This is particularly valuable when inherited or Refurbished servers arrive without complete historical documentation, because the current hardware can be mapped back to supported HPE option and spare references.

Plan Future Expansion before Filling Channels

Sixteen-gigabyte modules provide a modest capacity increment, but every DIMM also consumes a slot. Before expanding a server with more modules from this family, administrators can consider expected workload growth and remaining channel capacity. The server’s supported population sequence should guide the layout, while the assembly number helps keep newly added memory aligned with the existing family.

Physical Identification Can Help Remote Support

When an engineer cannot immediately access the server’s purchasing history, a clear photograph of the DIMM label can provide P43324-0A1 for remote identification. The assembly can then be mapped to P48499-001 before replacement stock is selected. This is useful for distributed estates where procurement and hands-on maintenance are handled by different teams.

Keep Memory Families Separate in Stock

Labelling DDR5-4800 and DDR5-5600 stock by exact HPE references reduces the chance of mixing speed families during urgent service. The assembly number provides a practical label for the module already installed.

Assembly Cross-References Improve Purchasing Accuracy

When a quotation uses P48499-001 but the installed DIMM shows P43324-0A1, the documented relationship explains why the numbers differ. Procurement can approve the replacement with a clearer understanding of the part family instead of rejecting it as a mismatch or creating another duplicate inventory record.

It also gives engineers a consistent reference when memory is moved between compatible systems during testing, repair or hardware consolidation.

This supports clearer long-term asset management.
