HPE Gen10 Plus Server Memory
Every HPE ProLiant Gen10 Plus server takes HPE DDR4-3200 SmartMemory: registered DIMMs from 8GB to 64GB and load-reduced DIMMs of 128GB and 256GB, on 3rd Gen Intel Xeon Scalable or AMD EPYC 7002 / 7003 processors. The Intel and AMD servers list different DDR4-3200 kits, so the server model, not the speed, decides which family to buy. The DDR4-2666 and DDR4-2933 kits sold for Gen10 are not listed for Gen10 Plus, and Gen11 DDR5 does not fit.
- 8 Gen10 Plus models, one memory page each
- DDR4-3200 RDIMM 8GB to 64GB, LRDIMM 128GB and 256GB
- Up to 8TB in the DL360, DL380, DL365 and DL385 Gen10 Plus
- 8 channels per processor, 2 slots each
Specifications match each model’s HPE ProLiant QuickSpecs; the model pages confirm every figure.
How processor, kit and speed fit together
Every kit is rated DDR4-3200. The processor and the population set the speed it actually runs at: on the Intel servers the processor tier decides, on the AMD servers the number of DIMMs per channel does.
| Processor | Servers | Kit family | Runs memory at |
|---|---|---|---|
| 3rd Gen Xeon Platinum 83xx / Gold 63xx | DL360, DL380 Gen10 Plus | DDR4-3200 (Intel list) | 3200 MT/s (Gold 6330: 2933; Gold 6338N and 6330N: 2667) |
| 3rd Gen Xeon Gold 53xx | DL360, DL380 Gen10 Plus | DDR4-3200 (Intel list) | 2933 MT/s (Gold 5318N: 2667) |
| 3rd Gen Xeon Silver 43xx | DL360, DL380 Gen10 Plus | DDR4-3200 (Intel list) | 2667 MT/s |
| AMD EPYC 7002 | DL325 and DL385 Gen10 Plus | DDR4-3200 (AMD list) | 3200 MT/s with one DIMM per channel, 2933 MT/s with two |
| AMD EPYC 7003 (and the 7xx2 models HPE keeps on the list) | DL325 Gen10 Plus v2, DL345, DL365 Gen10 Plus, DL385 Gen10 Plus v2 | DDR4-3200 (AMD list) | 3200 MT/s; the 256GB kit, and any kit on a 7xx2 processor, runs 2933 MT/s with two DIMMs per channel |
Each processor has 8 channels with 2 slots per channel; one DIMM in every channel gives full bandwidth. HPE: DIMMs need to be selected in even quantities on the Intel servers. The model pages give the population counts the picker uses.
Gen10 Plus or Gen10? How to tell
Gen10 Plus servers share model names with Gen10 but take a different memory family. On the Intel side the processor decides; on the AMD side an EPYC 7002 can sit in either generation, so go by the server model.
| Gen10 Plus | Gen10 | |
|---|---|---|
| Memory | DDR4-3200 RDIMM and LRDIMM | DDR4-2933 (2nd Gen Xeon, EPYC 7002) or DDR4-2666 (1st Gen Xeon, EPYC 7001) |
| Intel processors | 3rd Gen Xeon Scalable: Silver 43xx, Gold 53xx / 63xx, Platinum 83xx | 1st and 2nd Gen Xeon Scalable: x1xx and x2xx model numbers |
| AMD processors | EPYC 7002 (DL325 and DL385 Gen10 Plus), EPYC 7003 (DL325 Gen10 Plus v2, DL345, DL365 Gen10 Plus, DL385 Gen10 Plus v2) | EPYC 7001 and 7002 (DL325 Gen10, DL385 Gen10) |
| Kit part numbers look like | P06029-B21, P07638-B21, P40007-B21 | P00922-B21, P19042-B21, 815098-B21 |
Gen10 kits have their own pages: 2nd Gen CPU (DDR4-2933) and 1st Gen CPU (DDR4-2666).
Read the processor model. The second digit of an Intel Xeon Scalable model number is its generation: Gold 6338 and Silver 4314 are 3rd Gen (Gen10 Plus); Gold 6230 and Silver 4210 are 2nd Gen, Gold 6130 and Silver 4110 are 1st Gen (both Gen10).
Where to find the processor model: iLO › Information › System Information › Processors. On Windows, Task Manager › Performance › CPU. On Linux, lscpu | grep "Model name".
Adding to memory that is already installed? Read the HPE part number on the DIMM label and buy that number. It cannot be wrong.
Rules that hold for every Gen10 Plus server
1 RDIMM or LRDIMM, never both
The 8GB to 64GB kits are RDIMMs; the 128GB and 256GB kits are LRDIMMs. A server takes one or the other, and HPE does not support mixing 3DS with non-3DS DIMMs. If memory is already installed, match the part number on the existing DIMM label.
2 Buy from the list for your server
The Intel and AMD Gen10 Plus servers list different DDR4-3200 part numbers. The Fits line under each kit names the servers that list it; the model page is the full answer.
3 Fill channels for bandwidth
Eight matching DIMMs per processor fill every channel once. Four per processor is a sensible budget build; sixteen per processor is the capacity maximum. Populate both processors identically.
HPE Gen10 Plus memory questions
How much memory can an HPE Gen10 Plus server hold?
Up to 8TB in the DL360, DL380, DL365 and DL385 Gen10 Plus and the DL385 Gen10 Plus v2 (32 slots with 256GB LRDIMMs) and 4TB in the DL325 Gen10 Plus, DL325 Gen10 Plus v2 and DL345 Gen10 Plus (16 slots; the DL325 Gen10 Plus page explains how HPE prints that figure). With 64GB registered DIMMs the maxima are 2TB and 1TB. A single processor can use only its 16 slots.
What type of memory do HPE Gen10 Plus servers use?
HPE DDR4-3200 SmartMemory: registered DIMMs from 8GB to 64GB and load-reduced DIMMs of 128GB and 256GB. The entry servers (ML30 Gen10 Plus, DL20 Gen10 Plus, MicroServer Gen10 Plus v2) take DDR4-3200 unbuffered ECC DIMMs instead.
Can I use Gen10 DDR4-2933 or DDR4-2666 memory in a Gen10 Plus server?
No. The Gen10 Plus QuickSpecs list the DDR4-3200 kits only; the DDR4-2666 and DDR4-2933 kits for Gen10 servers are not listed for them. Match the HPE part number on an existing DIMM if you are adding memory.
Will the memory run at 3200 MT/s?
On the Intel servers only with a processor rated for it: most Platinum 83xx and Gold 63xx. Gold 53xx processors run memory at 2933 MT/s and Silver 43xx at 2667, and the N models lower still. On the AMD servers the kit runs at 3200 MT/s with one DIMM per channel and, on EPYC 7002, 2933 MT/s with two. The kit is still DDR4-3200; the processor clocks it lower.
What are the Optane 200 modules and the DIMM blank kit listed here?
Intel Optane 200 Series persistent memory is listed for the Intel Gen10 Plus servers only (3rd Gen Xeon) and needs a matching DDR4 configuration; it is not ordinary memory and the picker on each model page leaves it out. The DDR4 DIMM blank kit fills empty slots for airflow. Check HPE’s population rules before adding either.
Is this genuine HPE memory, and what is the warranty?
Yes. Every kit is a genuine HPE part, tested or factory sealed, and covered by our 5-year memory warranty. Most orders ship the same business day.
