HPE P43330-0A1 32GB DDR5-4800 Server Memory Kit

HPE P43330-0A1 32GB PC5-38400 DDR5-4800 Registered Module

P43330-0A1 is the number you are most likely to find printed on the label of a 32GB HPE DDR5 module taken from a Gen11 server. It is the HPE assembly number for the 32GB dual rank x8 PC5-4800B-R registered DIMM, the same module HPE sells as option kit P43328-B21 and supplies under spare number P48501-001.

Ordering by the assembly number is the simplest way to get a like for like match when you are replacing one module or adding more of the same. This page explains how to read the label, how the 0A1 suffix fits in, and which servers use the module.

Stock is offered in New and Refurbished condition, subject to availability. Select a condition on this page to see the price and details.

Reading A DDR5 Memory Label

A typical label on this module shows the HPE assembly number P43330-0A1 and a rating such as 32GB 2Rx8 PC5-4800B-R. Here is what each part means:

• 32GB is the module capacity
• 2Rx8 means two ranks built from x8 DRAM chips
• PC5-4800 is DDR5 at 4800 MT/s, which equals a PC5-38400 bandwidth rating
• B is the timing grade, matching HPE’s CAS 40-39-39 specification
• R confirms a registered DIMM

If a label you are matching shows 2Rx4 or a different speed, it belongs to a different kit, even if the capacity is the same.

One practical difference from DDR4 is that DDR5 modules carry their own power management chip, so voltage regulation happens on the DIMM rather than only on the motherboard. That makes careful handling even more important. Always power down the server, remove the power cords and use an anti-static strap before you touch the memory, and seat the module evenly until both latches close.

Assembly Revisions: 0A1 And 1A1

HPE assembly numbers identify a particular build of a module, and the suffix can change when HPE introduces a new build revision. Our range also includes P43330-1A1, which shares the same base number. If your server already contains modules with one suffix and you want to add the other, contact us first so we can check the details printed on both labels before you order.

Whichever revision you use, keep within HPE’s population rules for Gen11. On the DL380 Gen11, x4 and x8 modules cannot be mixed, 3DS and non-3DS modules cannot be combined, and DIMMs should be installed in even quantities.

Servers That Use P43330-0A1

HPE includes the matching P43328-B21 kit in the DL380 Gen11 QuickSpecs, with DDR5-4800 kits supported only on 4th Gen Xeon Scalable processors. Our product data and specialist resellers list the module for:

• HPE ProLiant DL380 Gen11
• HPE ProLiant ML350 Gen11
• HPE ProLiant DL320 Gen11
• HPE ProLiant DL360 Gen11 and DL380a Gen11
• HPE ProLiant DL110 Gen11, DL560 Gen11 and ML110 Gen11
• HPE Synergy 480 Gen11

AMD based Gen11 servers use HPE’s separate P50xxx-B21 kits, and Gen10 or Gen10 Plus servers need DDR4.

Frequently Asked Questions

Is P43330-0A1 the same module as P43328-B21?

Yes. P43330-0A1 is the assembly number printed on the module, P43328-B21 is the option kit number and P48501-001 is the spare number for the same 32GB DDR5-4800 RDIMM.

What does 2Rx8 PC5-4800B-R on the label mean?

It means dual rank built from x8 chips, DDR5 at 4800 MT/s with the B timing grade, and a registered DIMM.

Can I use P43330-0A1 alongside P43330-1A1 modules?

They share the same base number, but the suffix marks a different build. Send us both label details and we will check before you order.
