HPE Gen10 Memory (2nd Gen CPU)
HPE ProLiant Gen10 servers with 2nd Gen Intel Xeon Scalable processors (Bronze 32xx, Silver 42xx, Gold 52xx / 62xx, Platinum 82xx) take HPE DDR4-2933 SmartMemory: registered DIMMs from 8GB to 64GB and load-reduced DIMMs of 64GB and 128GB. The DL325 Gen10 with AMD EPYC 7002 processors takes its own DDR4-2933 kits. A Gen10 server with 1st Gen processors uses the DDR4-2666 kits instead, and HPE does not support mixing the two families.
- 12 Gen10 models, one memory page each
- DDR4-2933 RDIMM 8GB to 64GB, LRDIMM 64GB and 128GB
- Up to 6TB in the DL580 Gen10; 3TB in the DL360, DL380 and ML350 Gen10
- 6 channels per processor, 2 slots each
Specifications match each model’s HPE ProLiant QuickSpecs; the model pages confirm every figure.
How processor and memory speed fit together
The kit speed is the fastest the DIMM can run. The processor sets the speed it actually runs at, so a Silver 4210 with DDR4-2933 kits runs them at 2400 MT/s and that is normal. Buy the kit family that matches the generation; the processor takes care of the rest.
| Processor | Examples | Kit to buy | Runs memory at |
|---|---|---|---|
| 2nd Gen Xeon Platinum 82xx / Gold 62xx | 8260, 6230, 6248 | DDR4-2933 | 2933 MT/s |
| 2nd Gen Xeon Gold 52xx | 5218, 5220, 5222 | DDR4-2933 | 2666 MT/s (Gold 5222: 2933) |
| 2nd Gen Xeon Silver 42xx | 4208, 4210, 4214 | DDR4-2933 | 2400 MT/s |
| 2nd Gen Xeon Bronze 32xx | 3204, 3206R | DDR4-2933 | 2133 MT/s |
| AMD EPYC 7002 (DL325 Gen10) | 7302P, 7402P, 7502P, 7702 | DDR4-2933 (AMD list) | 2933 MT/s with one DIMM per channel, 2666 MT/s with two |
Each Intel processor has 6 channels with 2 slots per channel; six matching DIMMs per processor fill every channel once. The DL325 Gen10 has 8 channels with 2 slots each. The model pages give the population counts the picker uses.
1st or 2nd Gen? How to tell
The same Gen10 server takes either processor generation, and the generation decides the kit family. Nothing on the outside of the server tells you which one is installed; the processor model number does.
| 2nd Gen Xeon Scalable | 1st Gen Xeon Scalable | |
|---|---|---|
| Kit family | DDR4-2933 | DDR4-2666 |
| Model numbers | Bronze 32xx, Silver 42xx, Gold 52xx / 62xx, Platinum 82xx: a 2 in the second position | Bronze 31xx, Silver 41xx, Gold 51xx / 61xx, Platinum 81xx: a 1 in the second position |
| AMD equivalent | EPYC 7002 (DL325 Gen10): DDR4-2933 | EPYC 7001 (DL325 Gen10): DDR4-2666 |
| Kit part numbers look like | P00918-B21 to P00930-B21, P19040-B21 to P19047-B21 | 815097-B21 to 815102-B21, 838079-B21 to 838089-B21 |
1st Gen kits have their own page: HPE Gen10 Memory (1st Gen CPU).
Read the processor model. The second digit tells you the generation: Silver 4210, Gold 5218 and Gold 6230 are 2nd Gen; Silver 4110, Gold 5118 and Gold 6130 are 1st Gen. A 3 in that position (Gold 6338) means a Gen10 Plus server, which takes DDR4-3200.
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 (2nd Gen CPU) server
1 Match the kit to the processor generation
DDR4-2933 kits are listed for 2nd Gen processors and DDR4-2666 kits for 1st Gen. Mixed configurations are not supported and the server may not boot. If memory is already installed, match the part number on the existing DIMM label.
2 Populate both processors identically
Whatever you install on processor 1, install the same on processor 2, and keep every DIMM in a bank the same capacity and rank. HPE marks odd counts above one per processor unbalanced.
3 Buy -B21, not -F21
Both suffixes describe the same module, but -F21 is sold only inside a factory-built server. The -B21 kits on this page are the ones you can buy and install yourself.
HPE Gen10 (2nd Gen CPU) memory questions
How much memory can an HPE Gen10 server hold?
It depends on the model: 6TB in the DL580 Gen10 (48 slots), 3TB in the DL360, DL380 and ML350 Gen10 (24 slots), 2TB in the BL460c Gen10 (16 slots) and the DL325 Gen10 (16 slots), and 192GB in the ML110 Gen10 (6 slots). Each figure assumes the largest DIMM in every slot; with registered DIMMs the maxima are lower. The model pages spell them out.
What type of memory do Gen10 servers with 2nd Gen processors use?
HPE DDR4-2933 SmartMemory: registered DIMMs from 8GB to 64GB and load-reduced DIMMs of 64GB and 128GB. The DL325 Gen10 with EPYC 7002 lists its own DDR4-2933 kits (P19040-B21 to P19047-B21).
Can I use DDR4-2666 memory with a 2nd Gen processor?
Buy the kit family HPE lists for your processor generation. If the server already has memory installed, add the same part number rather than mixing families; mixed configurations are not supported.
Will the memory run at 2933 MT/s?
Only with a processor rated for it, such as a Xeon Gold 62xx, Platinum 82xx or Gold 5222. Other Gold 52xx processors run memory at 2666, Silver at 2400 and Bronze at 2133 MT/s. The kit still has to be the DDR4-2933 family; the processor simply clocks it lower.
What about Intel Optane DC persistent memory?
The Optane DC Persistent Memory 100 Series kits listed here need a 2nd Gen Xeon Scalable processor and a matching DDR4 configuration; they are not ordinary memory kits and the picker on each model page leaves them out. Check HPE’s population rules before adding them to an existing server.
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.
