Overview
P48501-001 is the HPE spare part number for 32GB Dual Rank x8 DDR5-4800 CAS-40-39-39 EC8 Registered Smart Memory for Gen11 servers. This is the number that appears in HPE service documentation, iLO memory fault entries, and on the label of the module itself, so it is what you will find when tracing a failed DIMM. The module is a 288-pin DDR5 registered DIMM running at 4800 MHz (PC5-38400) with CL40 (40-39-39) timings, x8 chip organization, dual rank, ECC, at 1.1 V. Spare-numbered memory ships as the bare module, without option-kit retail packaging.

FREQUENTLY ASKED QUESTIONS ABOUT P48501-001
What is the difference between P48501-001 and P43328-B21?
They are the same physical memory module under different HPE numbering schemes. P48501-001, the number on this page, is the spare part number used by HPE service channels and printed on the module label. P43328-B21 is the option part number, the orderable kit used when configuring or upgrading a server. This family also includes one assembly revision, listed in the cross-reference block on this page. An assembly number identifies a specific build or revision level of the same module.
Will this module work in my server?
It is supported in HPE Gen11 servers with 4th Gen CPUs: DL110, DL320, DL360, DL380, DL380a, DL560, ML110, ML350, and Synergy 480. This is a system-specific upgrade type, so it is validated for those platforms rather than sold as generic DDR5 memory. Confirm your server model and processor generation before installing, and follow the DIMM population rules in the server maintenance and service guide.
What are the exact specifications of the module?
Capacity is 32 GB in a 288-pin DIMM form factor using DDR5 SDRAM. Speed is 4800 MHz (PC5-38400) with latency timings of CL40 (40-39-39). The module is dual rank with x8 chip organization, registered, with ECC data integrity checking, and operates at 1.1 V. Physical dimensions are 7.5 in wide, 3.5 in high, and 0.8 in deep, with a weight of 1.41 oz.
Can I mix this DIMM with the memory already installed in my server?
Mixing rules are defined by HPE per platform, not by the DIMM alone. Matching characteristics matter: 32 GB capacity, DDR5-4800, dual rank, x8 organization, registered, and ECC. When replacing a failed module, the safest approach is to match the specifications of the other DIMMs in the same channel and follow the population guidelines in your server's maintenance and service guide.
What is an OEM model number and which one applies here?
An OEM model number is the manufacturer's own equivalent designation for the same product, useful when cross-referencing documentation or parts lists from different sources. For this module, the OEM manufacturer equivalent part number is HPE P43328-B21. Searching on either that number or the spare number on this page should lead you to the same 32GB dual rank x8 DDR5-4800 registered ECC module.
