HPE ProLiant DL560 Gen9 Processors
Intel Xeon processor options for the HPE ProLiant DL560 Gen9. This is a four-socket server that runs one, two or four processors — never three — and going past two also requires the DL560 Gen9 CPU Mezzanine Board kit, which carries the third and fourth sockets and their DIMM slots. The processor part numbers listed below carry no live price and render a quote request rather than a figure.
DL560 Gen9 Processor Specifications
- Sockets: four, on the Intel C610 series chipset; supported populations are one, two or four, and three is not among them
- Families: Intel Xeon E5-4600 v3 and Intel Xeon E5-4600 v4, spanning six to 22 cores, 1.7GHz to 2.9GHz and 105W to 135W, with 25MB to 55MB of level 3 cache
- Four-processor requirement: the HPE ProLiant DL560 Gen9 CPU Mezzanine Board Kit, part number 795107-B21, is required for any four-processor configuration
- Kit convention: HPE ships the first processor as an xxxxxx-L21 kit and each additional one as an xxxxxx-B21, so four processors is one -L21 and three -B21
- Mixing: not supported — every processor installed in the server must be the same model
- Features: Hyper-Threading on every listed processor except the E5-4627 v3 and E5-4627 v4, and Turbo Boost on every one except the E5-4610 v3 and E5-4610 v4
The step after two processors is four. HPE supports one, two or four on this platform and nothing in between, so a half-populated DL560 Gen9 upgrades by three identical processors plus the CPU Mezzanine Board kit. Every processor must be the same model, and each one brings twelve DIMM slots with it.
What does each processor unlock besides cores?
| Processors installed | DIMM slots available | PCIe slots available | Also required |
|---|---|---|---|
| One | 12 of 48 | 3, on the primary riser | — |
| Two | 24 of 48 | 4, or 7 with the secondary riser kit | Secondary riser kit for slots 4 to 6 |
| Four | all 48 | 7 with the secondary riser kit | CPU Mezzanine Board kit, plus three matching processors |
On a two-socket server the second processor is mostly about cores. Here it is about the machine: a DL560 Gen9 running one processor has a quarter of its memory capacity and three of its seven expansion slots, so the sockets are what turn the chassis into the platform it was bought as. And because three is not a supported population, the step after two is four — three more identical kits plus the mezzanine board, which is the number worth knowing before a budget is set.
Choosing the Right DL560 Gen9 Processor
- Plan for two or four, not three. The jump from a two-processor machine is to a full four, so price the mezzanine board and three processors together rather than one at a time.
- Every processor must be the same model. Mixing different processor models in one server is not supported, so an upgrade means matching what is fitted or replacing all of them.
- Know which kit suffix you need. The first processor in a server is an -L21 kit and every additional one is a -B21; the two are not interchangeable when ordering.
- The processor sets the memory ceiling. An E5-4610v3 holds DDR4 to 1600MT/s and an E5-4610v4 to 1866MT/s, where the faster v4 parts support 2400MT/s.
- Check the power budget before the core count. Four 135W processors alongside 48 DIMMs and 24 drives is a different supply calculation from one or two, and the 1500W supply needs a 200 to 240 VAC feed.

DL560 Gen9 Processors FAQ
How many processors does a DL560 Gen9 support?
One, two or four Intel Xeon E5-4600 v3 or v4 processors. Three processors is not a supported population, and four requires the HPE ProLiant DL560 Gen9 CPU Mezzanine Board Kit, 795107-B21.
Can I put three processors in a DL560 Gen9?
No. HPE documents the supported populations as one, two or four. The step up from two is four, which also means fitting the CPU Mezzanine Board kit.
Can I mix different processor models in a DL560 Gen9?
No. Mixing different processor models in the same server is not supported. Every installed processor has to be the same model.
What is the difference between an L21 and a B21 processor kit?
The -L21 kit is the first processor in a server and each additional processor is a -B21 kit. Four processors is ordered as one -L21 and three -B21.
What is the fastest processor the DL560 Gen9 takes?
The listed range tops out at the 22-core E5-4669v4 at 2.2GHz with 55MB of cache and a 135W envelope. The highest clock among them is the six-core E5-4655v3 at 2.9GHz.
Does adding processors do anything besides add cores?
Yes, and on this server it is the main reason. Each processor brings twelve DIMM slots with it, and slot seven and the secondary riser's slots only become available once a second processor is installed.
