HPE ProLiant DL325 Gen10 Plus v2 Memory
Upgrade your HPE ProLiant DL325 Gen10 Plus v2 with genuine HPE DDR4 Smart Memory, in stock new and refurbished and tested before shipping. One processor drives all 16 DIMM slots on this 1U platform — 8 channels at 2 DIMMs per channel — and the DIMM type you pick sets the ceiling at 1TB of RDIMM or 4TB of LRDIMM.
DL325 Gen10 Plus v2 Memory Specifications
- Memory type: HPE DDR4 Smart Memory in Registered (RDIMM) and Load Reduced (LRDIMM) form — mixing RDIMM and LRDIMM is not supported
- Slots: 16 DIMM slots on the single processor — 8 channels per processor, 2 DIMMs per channel
- Speed: DDR4-3200 throughout — 8GB through 128GB kits hold 3200 MT/s at 1 and 2 DIMMs per channel; the 256GB kit runs 3200 MT/s at 1 DPC, 2933 MT/s at 2 DPC
- RDIMM kits: 8GB 1Rx8, 16GB 1Rx4, 16GB 2Rx8, 32GB 2Rx4, and 64GB 2Rx4 — all DDR4-3200 CAS-22-22-22
- LRDIMM kits: 128GB quad-rank x4 and 256GB octal-rank x4 3DS — the 256GB module requires the Max Performance Fan Kit
- Maximum capacity: 1.0TB as 16 × 64GB RDIMM, or 4.0TB as 16 × 256GB LRDIMM; every listed EPYC supports up to 4TB
Pick your DIMM type before your capacity. RDIMM and LRDIMM cannot be mixed in a DL325 Gen10 Plus v2, and the type sets the ceiling — 1.0TB with 16 × 64GB RDIMMs against 4.0TB with 16 × 256GB LRDIMMs. Mixing x4 and x8 modules is not allowed either.
How much memory can the DL325 Gen10 Plus v2 hold?
| Configuration | Total capacity | Speed | Notes |
|---|---|---|---|
| 8 × 32GB RDIMM | 256GB | 3200 MT/s | One DIMM per channel, all 8 channels filled |
| 16 × 32GB RDIMM | 512GB | 3200 MT/s | Slots full, still at 3200 MT/s |
| 16 × 64GB RDIMM | 1.0TB | 3200 MT/s | RDIMM maximum for the platform |
| 16 × 128GB LRDIMM | 2.0TB | 3200 MT/s | Quad-rank x4 Load Reduced modules |
| 16 × 256GB LRDIMM 3DS | 4.0TB | 2933 MT/s | Platform maximum; needs the Max Performance Fan Kit |
The 32GB and 64GB RDIMMs are the sweet spot — dual-rank x4 modules that hold 3200 MT/s at one or two per channel. Only the 256GB LRDIMM trades speed for capacity, dropping to 2933 MT/s once both slots in a channel are filled.
Choosing the Right DL325 Gen10 Plus v2 Memory
- Fill all 8 channels before doubling up: a balanced 8-DIMM bank uses every channel on the processor before you stack a second DIMM per channel.
- Don't mix types or widths: RDIMM and LRDIMM cannot be mixed, and mixing x4 and x8 modules is not allowed — see our note on memory rank in HPE servers.
- Check the CPU footnote: the QuickSpecs processor table also lists 7xx2 parts, and those cannot run 2 DIMMs per channel at 3200 MT/s — they step down to 2933 MT/s.
- Plan cooling with 256GB modules: that kit is the only one that obliges the Max Performance Fan Kit.
- Background reading: why memory speed matters and what CAS latency means.

DL325 Gen10 Plus v2 Memory FAQ
How much RAM does the HPE ProLiant DL325 Gen10 Plus v2 support?
Up to 1.0TB with RDIMMs (16 x 64GB DDR4-3200) or up to 4.0TB with LRDIMMs (16 x 256GB). All 16 slots hang off the single processor, and every EPYC listed supports up to 4TB.
What type of memory does the DL325 Gen10 Plus v2 use?
HPE DDR4 Smart Memory at DDR4-3200: Registered DIMMs from 8GB to 64GB and Load Reduced DIMMs at 128GB and 256GB. RDIMM and LRDIMM cannot be mixed in the same server, and mixing x4 with x8 modules is not allowed.
Does the DL325 Gen10 Plus v2 slow down when all 16 DIMM slots are filled?
Not with most kits. The 8GB through 128GB modules run 3200 MT/s at both 1 and 2 DIMMs per channel. Only the 256GB LRDIMM steps down, from 3200 MT/s at 1 DIMM per channel to 2933 MT/s at 2 DIMMs per channel.
How many memory channels does the DL325 Gen10 Plus v2 have?
Eight per processor, with two DIMM slots on each channel for 16 slots total. Fill all eight channels with one DIMM each before adding a second DIMM per channel.
Do 256GB LRDIMMs need anything extra in the DL325 Gen10 Plus v2?
Yes. The QuickSpecs states that when the 256GB LRDIMM is supported, the DL325 Gen10 Plus v2 Max Performance Fan Kit must be selected. Budget for the fan kit alongside the memory.
Can I reuse DDR4 memory from another HPE ProLiant in this server?
Only if the exact HPE part number is listed for this platform. Memory qualification is per server family, so match the part number rather than the DDR4 generation alone.
