Overview
P43330-0A1 is the HPE assembly part number for 32GB Dual Rank x8 DDR5-4800 CAS-40-39-39 EC8 Registered Smart Memory for Gen11 servers. If you are reading this number off a module label or found it in an HPE PartSurfer lookup, it identifies a 32GB 288-pin DDR5 registered DIMM running at 4800 MHz (PC5-38400) with CL40 (40-39-39) timings, x8 chip organization, dual rank construction, ECC data integrity checking and 1.1 V operation. Assembly numbers like this one appear on the physical label and in service documentation rather than on purchase orders, so confirming the mapping to the orderable number is usually the next step.

FREQUENTLY ASKED QUESTIONS ABOUT P43330-0A1
What is the difference between P43330-0A1, P43328-B21 and P48501-001?
All three numbers refer to the same physical 32GB DDR5-4800 registered DIMM. P43330-0A1, the number on this page, is the HPE assembly number, which is what typically appears on the module label and in PartSurfer results. P43328-B21 is the option part number used when ordering the module as a configurable upgrade. P48501-001 is the spare part number used for service replacement. The hardware itself is identical across all three.
How do I confirm the module in my hand matches this page?
Check the label for the assembly number P43330-0A1, then verify the printed specifications: 32 GB capacity, DDR5 SDRAM, 288-pin DIMM form factor, 4800 MHz (PC5-38400) rated speed, CL40 (40-39-39) latency, dual rank, x8 chip organization, registered with ECC, and 1.1 V operating voltage. A module matching all of those attributes is the same product described here.
Which servers does this module go into?
This is a system-specific upgrade for HPE Gen11 servers using 4th Gen CPUs: DL110 Gen11, DL320 Gen11, DL360 Gen11, DL380 Gen11, DL380a Gen11, DL560 Gen11, ML110 Gen11, ML350 Gen11, and Synergy 480 Gen11. It is a registered DDR5 DIMM and is not intended for platforms outside that list.
What are the physical dimensions of the module?
The module measures 7.5 in wide, 3.5 in high and 0.8 in deep as packaged, and weighs 1.41 oz. It uses the standard 288-pin DIMM form factor for DDR5 registered memory, so it seats in the DIMM slots of the supported Gen11 servers listed for this part.
