HPE ProLiant BL460c Gen9 Processors
Genuine HPE processor option kits for the HPE ProLiant BL460c Gen9, new and refurbished. The blade takes one or two Intel Xeon E5-2600 v3 series processors on the Intel C610 chipset, and HPE requires every processor in the blade to be identical — so a second CPU has to match the first exactly.
BL460c Gen9 Processor Specifications
- Sockets: two on the Intel C610 chipset, upgradeable from one processor to two
- Family stocked: Intel Xeon E5-2600 v3, from the four-core E5-2637 v3 at 3.5GHz up to the eighteen-core E5-2699 v3; the platform also documents E5-2600 v4 parts to twenty-two cores
- Cache: 10MB to 45MB of level 3 cache across the v3 kits listed, scaling with core count
- Wattage: 55W on the eight-core E5-2630L v3 through 145W on the E5-2697 v3 and E5-2699 v3, with an L after the model number denoting the lower-wattage parts
- Features: Intel Hyper-Threading and Turbo Boost on every listed model except the E5-2603 v3 and E5-2609 v3
- Kit contents: every processor kit here is complete with heatsink and fans
The fastest kits cost you four DIMM slots. With an E5-2699 v3, E5-2697 v3, E5-2667 v3, E5-2643 v3 or E5-2637 v3 fitted, DIMM slots 4 and 5 are not accessible, leaving twelve usable slots in a two-processor blade instead of sixteen. On a memory-bound machine a mainstream part such as the E5-2650 v3 is worth more than the extra cores.
How many cores, and at what cost in slots?
| Example kit | Cores and clock | Wattage | DIMM slots available |
|---|---|---|---|
| E5-2699 v3 | 18 cores at 2.3GHz | 145W | 12 with two processors — slots 4 and 5 close |
| E5-2637 v3 | 4 cores at 3.5GHz | 135W | 12 with two processors — slots 4 and 5 close |
| E5-2650 v3 | 10 cores at 2.3GHz | 105W | All 16 |
| E5-2630L v3 | 8 cores at 1.8GHz | 55W | All 16 |
The trade on this blade is not just cores against clock, it is cores against memory slots. HPE documents that the E5-2699 v3, E5-2697 v3, E5-2667 v3, E5-2643 v3 and E5-2637 v3 make DIMM slots 4 and 5 inaccessible, leaving twelve slots in a two-processor blade rather than sixteen. If the machine is memory-bound rather than core-bound, a mainstream part such as the E5-2650 v3 keeps all sixteen slots and the capacity that goes with them.
Choosing the Right BL460c Gen9 Processor
- Both sockets must carry the same part. HPE does not support mixing processor models, so going from one CPU to two means a kit identical to the one already fitted.
- A second processor does three things. It adds cores, it opens the other eight DIMM slots, and it brings up mezzanine expansion slot 2 — which is often the real reason to fit one.
- Check the DIMM slot restriction before buying a top-bin part. Five of the v3 models close slots 4 and 5, which can cost more in memory capacity than the extra cores are worth.
- Hyper-Threading and Turbo Boost are near-universal here. Every listed v3 model carries both except the E5-2603 v3 and E5-2609 v3, so those two are the ones to check against a licensing or thread-count assumption.
- Buy the memory kit to match the processor family. The v3 kits pair with DDR4-2133 SmartMemory in this listing; DDR4-2400 kits are the ones listed against E5-2600 v4 processors.

Processor choice sets the memory ceiling and opens the second mezzanine slot — see BL460c Gen9 memory and networking adapters alongside this page. Also available: BL460c Gen9 drives and storage controllers, or the full BL460c Gen9 parts listing. The adjacent generations are BL460c Gen8 processors and BL460c Gen10 processors, and every model we stock is indexed under HPE parts by server model.
BL460c Gen9 Processors FAQ
Which processors does the BL460c Gen9 support?
Intel Xeon E5-2600 v3 and E5-2600 v4 series, one or two per blade, on the Intel C610 chipset. The kits listed here are the v3 series, running from the four-core E5-2637 v3 to the eighteen-core E5-2699 v3.
Can I mix different processors in a BL460c Gen9?
No. HPE states that all processors within the server must be identical and that mixing different processor models is not supported. Both sockets have to carry the same part number.
Does adding a second processor do anything besides add cores?
Yes, two things. It makes the other eight DIMM slots usable, and it brings up the second mezzanine expansion slot, which is wired to processor socket 2 and is dead without a CPU there.
Do BL460c Gen9 processor kits include a heatsink?
Yes. Every processor kit listed for this blade comes complete with heatsink and fans, so nothing extra is needed to fit it.
Which processors cost me DIMM slots?
The E5-2699 v3, E5-2697 v3, E5-2667 v3, E5-2643 v3 and E5-2637 v3. With any of these fitted, DIMM slots 4 and 5 are not accessible, leaving twelve usable slots in a two-processor blade.
Why do some processor kits show a quote link instead of a price?
Those part numbers have no live product behind them, so the page renders a quote link rather than a price. Processor pricing on this generation moves and availability is uneven.
