HPE ProLiant DL365 Gen10 Plus Memory
Upgrade your HPE ProLiant DL365 Gen10 Plus with genuine HPE DDR4 Smart Memory, in stock new and refurbished and tested before shipping. The platform carries 32 DIMM slots — 16 per processor, 8 channels each, 2 DIMMs per channel — and every kit listed for it is a DDR4-3200 Registered DIMM.
DL365 Gen10 Plus Memory Specifications
- Memory type: HPE DDR4 Smart Memory, Registered (RDIMM) — the option list for this server is RDIMM only
- Slots: 32 DIMM slots — 16 per processor, 8 channels per processor, 2 DIMMs per channel; the base-configuration note states 32 slots require two processors
- Capacities offered: 8GB, 16GB, 32GB, and 64GB kits, every one DDR4-3200 CAS-22-22-22 Registered Smart Memory
- Speed: 3200 MT/s SKUs are stated to run 3200 MT/s at both 1 and 2 DIMMs per channel, and maximum memory speed is limited by the processor selection
- Per-processor ceiling: the note under the processor table states all AMD EPYC processors support up to 4TB of memory per single CPU
- Protection and blanks: Advanced ECC; the DDR4 DIMM blank kit (P07818-B21) is required for empty slots and cannot be selected when 32 DIMMs are ordered
Pick a DIMM width and stay on it. The memory notes state that mixing x4 and x8 memory is not allowed. The 8GB kit and the dual-rank 16GB kit are x8; the single-rank 16GB, 32GB, and 64GB kits are x4 — so what is already installed decides which half of the list you can order from.
What memory does the DL365 Gen10 Plus take?
| Capacity | Rank and width | Speed grade | HPE part number |
|---|---|---|---|
| 8GB | Single Rank x8 | DDR4-3200 CAS-22-22-22 | P07638-B21 |
| 16GB | Single Rank x4 | DDR4-3200 CAS-22-22-22 | P07640-B21 |
| 16GB | Dual Rank x8 | DDR4-3200 CAS-22-22-22 | P07642-B21 |
| 32GB | Dual Rank x4 | DDR4-3200 CAS-22-22-22 | P07646-B21 |
| 64GB | Dual Rank x4 | DDR4-3200 CAS-22-22-22 | P07650-B21 |
Width matters more than it looks. The notes state that mixing x4 and x8 memory is not allowed, splitting this short list in two: the 8GB and dual-rank 16GB kits are x8, the single-rank 16GB, 32GB, and 64GB kits are x4.
Choosing the Right DL365 Gen10 Plus Memory
- Pick a width and stay on it. x4 and x8 DIMMs cannot be mixed, so a server on 64GB x4 kits stays on x4 parts.
- The processor sets the ceiling. Maximum memory speed is limited by the processor selection, and every EPYC 7003 model is listed at 3200 MT/s.
- Half the slots belong to the second processor. The memory table gives 16 DIMM slots per processor; the base-configuration note states 32 slots require two processors.
- Fill empty slots with blanks. The DDR4 DIMM blank kit is required for empty DIMM slots, and cannot be selected when 32 DIMMs are ordered.
- Background reading: memory rank, why memory speed matters, and what CAS latency means.

DL365 Gen10 Plus Memory FAQ
How much memory does the HPE ProLiant DL365 Gen10 Plus support?
The server has 32 DIMM slots, 16 per processor, and the base-configuration note states all 32 require two processors. The memory option list for this platform is Registered DIMMs from 8GB to 64GB. Separately, the processor table lists a maximum memory of 4TB for every EPYC 7003 model.
What type of memory does the DL365 Gen10 Plus use?
HPE DDR4 Smart Memory Registered DIMMs (RDIMMs). Every kit listed for this server is DDR4-3200 CAS-22-22-22 Registered Smart Memory, in 8GB, 16GB, 32GB, and 64GB capacities.
Can I mix x4 and x8 DIMMs in a DL365 Gen10 Plus?
No. The memory notes state that mixing of x4 and x8 memory is not allowed. The 8GB single-rank kit and the 16GB dual-rank kit are x8; the 16GB single-rank, 32GB, and 64GB kits are x4.
Does the DL365 Gen10 Plus run at 3200 MT/s with both DIMMs per channel filled?
The QuickSpecs state that 3200 MT/s memory SKUs can run the transfer rate of 3200 MT/s at both 1 DIMM and 2 DIMMs per channel. They also state that the maximum memory speed is limited by the processor selection.
Do I need DIMM blanks in the DL365 Gen10 Plus?
Yes. The QuickSpecs state the DDR4 DIMM blank kit (P07818-B21) is required for empty DIMM slots. The same section notes that the blank kit cannot be selected when 32 DIMMs are ordered.
Can I use memory from another ProLiant in the DL365 Gen10 Plus?
Only when the exact HPE part number is listed for this platform. The DL365 Gen10 Plus memory list is DDR4-3200 Registered Smart Memory in 8GB, 16GB, 32GB, and 64GB kits - match one of those part numbers and keep the x4 or x8 width consistent with what is already installed.
