DL325 Gen12 at a glance

Processors

One 5th Gen AMD EPYC processor (single socket), a 9xx5 model such as the 9135, 9355P or 9555P.

The processor needs its own heat sink: Standard (P58456-B21) for 240W or less, Performance (P81955-B21) for 260W to 300W, and the Closed-loop Liquid Cooling Heat Sink (P81954-B21), with the Liquid Cooling fans, for 320W and above. With five 4EDSFF cages (20 E3.S), a processor of 240W or less takes the Performance heat sink too.

The standard and performance heat sinks need the Air Baffle Kit (P81928-B21). The GPU model takes no closed-loop heat sink, and its processors over 300W need a direct liquid cooling kit. DL325 Gen12 Processors

Memory

24 DIMM slots, 12 channels with 2 DIMMs each, for HPE DDR5-6400 registered kits from 32GB to 256GB. Up to 6TB with 256GB DIMMs in all 24 slots, or 3TB with one DIMM per channel. The server runs the kits at 5200 MT/s with one DIMM per channel and 4000 MT/s with two.

HPE does not support the 256GB DIMM with a processor over 300W, except in the GPU model. With five 4EDSFF cages and a processor over 300W, HPE does not support the 96GB or 128GB DIMMs either. 96GB and larger DIMMs need the Performance fans.

Fit 1, 2, 4, 6, 8, 10, 12, 16, 20 or 24 DIMMs; x4 and x8 kits do not mix, nor do 3DS and non-3DS kits. DL325 Gen12 Memory

Drives

Up to 10 SFF drives in the 8SFF model (an 8SFF backplane plus a 2SFF backplane, which rules out the media bay) or in the SFF/EDSFF model, 4 LFF in the 4LFF model, 20 E3.S NVMe in the SFF/EDSFF model, which mixes SFF and E3.S cages, or 4 SFF or 8 E3.S in the GPU model. Every SFF drive HPE lists is Basic Carrier (BC).

In the SFF/EDSFF model a front OCP slot or front NS204i-u takes one of the five cage positions and the media bay two. The NS204i-u v2 boot device holds two M.2 NVMe SSDs in RAID 1. DL325 Gen12 Drives

Storage controllers

HPE MR216i, MR408i and MR416i tri-mode controllers in OCP and PCIe form and the MR932i-p, plus the Smart Array E208e-p for external drives. One Smart Storage battery or capacitor per server. DL325 Gen12 Storage Controllers

Networking

No embedded network ports: a PCIe stand-up or OCP 3.0 adapter is required. OCP slot A (x16) is standard and slot B optional, x8 or x16 by its enablement kits; the SFF/EDSFF model adds two optional front OCP slots. A dedicated 1Gb iLO port. DL325 Gen12 Networking Adapters

Expansion

Up to 2 PCIe 5.0 x16 slots: slot 2, full-height, by default and slot 1 optional, low-profile or full-height. The GPU model has up to 6. Riser cards

Cooling

Seven fan kits in every configuration: Standard (P71954-B21) for processors of 240W or less, Performance (P71958-B21) for 260W to 300W, Liquid Cooling (P81953-B21) only with the liquid-cooling heat sink. With 240W or less the Performance fans are still needed in the SFF/EDSFF model, for the 2SFF backplane in the 8SFF model, 96GB and larger DIMMs, the NS204i-u boot device, GPUs and direct liquid cooling. Fan kits

Power

One or two HPE M-CRPS hot-plug power supplies: 800W Platinum, 1000W, 1500W or 2400W Titanium, or 1300W or 2200W -48VDC with their lug kits. These are M-CRPS supplies, not the Flex Slot supplies of the DL325 Gen11, and different types do not mix. DL325 Gen12 Power Supplies

Management

HPE iLO 7. Management hardware

Specifications from HPE QuickSpecs a50009232enw, version 13 (October 5, 2026). Memory figures match the DL325 Gen12 Memory page.

Before you order, make sure the server is a Gen12, not a Gen11. Both run 5th Gen AMD EPYC processors (9xx5, such as the EPYC 9135 and 9355P) and take the same DDR5-6400 kits. The Gen12 has 24 DIMM slots and iLO 7; the Gen11 has 12 slots and iLO 6, and its 4th Gen processors (9xx4, such as the EPYC 9124) take DDR5-4800 kits, which HPE does not list for the Gen12. The Gen12 takes M-CRPS power supplies, not the Gen11's Flex Slot ones. Find the processor model in iLO under System Information › Processors.

Gen10 Plus v2, Gen11 or Gen12? How to tell

A processor whose last digit is 3 means a Gen10 Plus v2, and a 4 means a Gen11. A 5 is listed for both the Gen11 and the Gen12, which also share the DDR5-6400 kits, so count the DIMM slots: 12 on the Gen11, 24 on the Gen12.

DL325 Gen12 parts questions

How much memory does the DL325 Gen12 support?

Up to 6TB: 256GB DDR5-6400 RDIMMs in all 24 slots, at 4000 MT/s. With one DIMM per channel the maximum is 3TB (12 x 256GB) at 5200 MT/s. HPE does not support the 256GB DIMM with a processor over 300W, except in the GPU model. 96GB and larger DIMMs need the Performance fans. Fit 1, 2, 4, 6, 8, 10, 12, 16, 20 or 24 DIMMs; x4 and x8 kits do not mix, nor do 3DS and non-3DS kits.

Which drives fit the DL325 Gen12?

2.5-inch SFF drives on HPE's Basic Carrier (BC) in SAS, SATA or U.3 NVMe; 3.5-inch LFF drives in SAS or SATA in the 4LFF model; and E3.S EC1 NVMe drives in the SFF/EDSFF and GPU models. Which interfaces work depends on whether the backplane is direct attached or connected to a storage controller.

How do I tell which processor my DL325 Gen12 has?

Read the processor model in iLO under System Information › Processors. Every processor HPE lists for the DL325 Gen12 is a 5th Gen AMD EPYC 9xx5 model, such as the 9135, 9355P or 9555P. Its wattage decides the heat sink and fans: Standard for 240W or less, Performance for 260W to 300W, closed-loop liquid cooling for 320W and above. With five 4EDSFF cages, a processor of 240W or less takes the Performance heat sink too. A 9xx4 processor, such as the 9124, means the server is a DL325 Gen11.

Is my server a DL325 Gen12, a Gen11 or a Gen10 Plus v2?

Count the DIMM slots, then check the processor. The Gen12 has 24 DIMM slots and iLO 7 and runs 5th Gen AMD EPYC processors (9xx5) with DDR5-6400 memory. The Gen11 has 12 slots and iLO 6 and runs 4th Gen processors (9xx4) or 5th Gen, with DDR5-4800 or DDR5-6400 memory. The Gen10 Plus v2 has 16 slots and runs EPYC 7003 processors (7xx3), or the 7232P, 7302P and 7402P, with DDR4-3200 memory. The Gen11 and Gen12 share the DDR5-6400 kits, so check that a part number is on the page for your server before you buy.

Are refurbished parts on this list too?

Yes. A refurbished part carries the same HPE part number as a new one, so it is listed here under that number, and each listing shows its condition. Every part ships tested or factory sealed.

What warranty comes with DL325 Gen12 parts?

A replacement warranty of 1 to 5 years, depending on the part: memory is covered for 5 years, and many other parts for 1 or 3 years.
