HPE ProLiant DL325 Gen11 Processors
Genuine HPE-qualified AMD EPYC processors for the HPE ProLiant DL325 Gen11, new and refurbished, alongside the heat sink kits they need. This is a single-socket platform: one 4th Generation EPYC 9004 (DDR5-4800) or one 5th Generation EPYC 9005 (DDR5-6400) in a 6096-pin LGA SP5 socket.
DL325 Gen11 Processor Specifications
- Families: 4th Generation AMD EPYC 9004 up to 128 cores, or 5th Generation AMD EPYC 9005 up to 160 cores — one processor per server
- Range: 8-core parts at 125W through 160-core parts at 390W, with default cTDPs from 125W to 400W
- Cache: 64MB to 512MB of L3 on standard models, and up to 1150MB on the 4th Gen X-series parts
- Memory support: the processor generation sets the DDR5 grade — 4800 MT/s on 4th Gen, 6400 MT/s on 5th Gen — and every model addresses up to 3TB
- I/O: 128 PCIe 5.0 lanes per processor, feeding both risers and both OCP 3.0 slots
- Cooling: Standard heat sink up to 240W, Performance heat sink through 300W, and a closed-loop liquid cooling heat sink at 320W and above
Processors ship without heat sinks. Order by wattage: Standard up to 240W, Performance through 300W, and closed-loop liquid cooling at 320W and above. The DL325 Gen11 is single-socket, so the one processor you choose also fixes your DDR5 grade at 4800 or 6400 MT/s.
Which processors does the DL325 Gen11 support?
| Tier | Examples | Best for |
|---|---|---|
| High core count | 5th Gen EPYC 9845 (160 cores) and 9745 (128); 4th Gen 9754 (128) | Virtualization and container density |
| High frequency (F parts) | 5th Gen 9575F and 9175F (5.0 GHz max); 4th Gen 9374F | Per-core licensed databases |
| Large cache (X parts) | 4th Gen 9684X (1150MB L3), 9384X and 9184X (768MB) | Cache-bound technical computing |
| Entry | 5th Gen 9015 (8 cores, 125W) and 9115 (16 cores, 125W) | Cost- and power-sensitive 1U roles |
One EPYC 9845 puts 160 cores in a single 1U socket. Processors ship without heat sinks — add the kit matching the part's wattage, and note that 320W-and-above models also pull in the liquid cooling fan kit.
Choosing the Right DL325 Gen11 Processor
- There is no second socket to fill — the DL325 Gen11 is 1P, so all capacity planning happens inside one processor's 12 memory channels and 128 PCIe lanes.
- The CPU sets your memory speed: pair 4th Gen with DDR5-4800 kits and 5th Gen with DDR5-6400 — see DL325 Gen11 memory.
- Order the heat sink with the CPU — Standard, Performance, or closed-loop liquid cooling, chosen by the processor's wattage.
- Watch the thermal exceptions: the QuickSpecs cap ambient temperature at 25C for the EPYC 9254, and the 9384X is not supported in the EDSFF chassis at all.

DL325 Gen11 Processors FAQ
What processors does the HPE ProLiant DL325 Gen11 support?
One 4th Generation AMD EPYC 9004 processor (up to the 128-core 9754, DDR5-4800) or one 5th Generation AMD EPYC 9005 processor (up to the 160-core 9845, DDR5-6400), in a 6096-pin LGA SP5 socket.
What is the maximum core count of the DL325 Gen11?
160 cores, from a single 5th Generation EPYC 9845 at 2.1GHz base and 390W. On 4th Generation parts the ceiling is 128 cores with the EPYC 9754.
Is the DL325 Gen11 a single-socket or dual-socket server?
Single-socket. The DL325 Gen11 takes exactly one AMD EPYC processor. If you need two sockets in the same Gen11 family, that is the DL385 Gen11.
Do DL325 Gen11 processors come with heat sinks?
No - HPE processor SKUs ship as the processor only. Order the Standard heat sink for parts up to 240W, the Performance heat sink through 300W, or the closed-loop liquid cooling heat sink for 320W and above.
Which DL325 Gen11 processor is best for per-core software licensing?
The F-series high-frequency parts, such as the 16-core 9175F or the 24-core 9275F, both of which reach well above 4GHz. They deliver maximum performance per licensed core instead of maximum core count.
What do the X-series EPYC processors add?
L3 cache. The 4th Generation 9684X carries 1150MB of L3 and the 9384X and 9184X carry 768MB, against 64MB to 384MB on standard parts. That extra cache pays off in technical computing workloads whose working set fits in it.
