HPE ProLiant BL460c Gen10 Processors
Genuine HPE processor option kits for the HPE ProLiant BL460c Gen10, new and refurbished. The blade takes one or two Intel Xeon Scalable processors on the Intel C621 chipset, in either the first or the second generation, and the tier you choose sets the memory clock for the whole blade as firmly as it sets the core count.
BL460c Gen10 Processor Specifications
- Sockets: two on the Intel C621 chipset, upgradeable from one processor to two
- Families stocked: Intel Xeon Scalable in both generations — Bronze 3104 and 3204, Silver 41xx and 42xx, Gold 51xx, 52xx, 61xx and 62xx, Platinum 81xx and 82xx
- Core range: four cores on the Platinum 8256 and Gold 5222 up to 26 cores on the Platinum 8164, with 24-core Gold 6252 and 6262V parts alongside
- Interconnect and lanes: two UPI links at 10.4 GT/s on Platinum and Gold, 9.6 GT/s on Silver and Bronze, with 48 lanes of PCIe 3.0 per processor
- Memory clock by tier: 2933MT/s on Platinum 82xx and Gold 62xx, 2666MT/s on Gold 52xx, 2400MT/s on Silver 42xx and 2133MT/s on Bronze 32xx
- Speed Select: the Gold 6240Y and Silver 4214Y are configurable at boot to three core-count and frequency operating points, selected in the HPE ROM-based setup utility
- Cooling: processors of 135W or greater call for 10 fans in a c7000 enclosure for optimal performance
The tier is the memory decision as well as the core decision. A Bronze 3204 holds DDR4 at 2133MT/s whether two DIMMs are fitted or sixteen, where a Platinum 82xx or Gold 62xx part runs the same modules at 2933MT/s. On a bandwidth-bound workload that gap is worth more than the last few cores, and no memory kit can close it.
Which tier, and what does it cost you in memory speed?
| Tier | Example kit | Memory clock | Suits |
|---|---|---|---|
| Platinum 82xx, Gold 62xx | Gold 6248, 20 cores at 2.5GHz, 150W | 2933MT/s | Core count and memory bandwidth together |
| Gold 52xx | Gold 5218, 16 cores at 2.3GHz, 125W | 2666MT/s | General virtualisation on a modest power budget |
| Silver 42xx | Silver 4214, 12 cores at 2.2GHz, 85W | 2400MT/s | Density, and blades that share an enclosure power budget |
| Bronze 32xx | Bronze 3204, 6 cores at 1.9GHz, 85W | 2133MT/s | Light infrastructure roles where clock hardly matters |
This is the decision the Xeon Scalable generation added, and it is easy to get wrong. On earlier blades the memory clock fell as the channels filled; here it does not move with population at all, and is fixed instead by the badge on the processor. A Bronze 3204 holds the memory at 2133MT/s with sixteen DIMMs or two, so on a bandwidth-bound workload the tier is worth more than the last few cores.
Choosing the Right BL460c Gen10 Processor
- Both sockets must carry the same part. Going from one processor to two means a kit identical to the one already fitted, not simply one of the same tier.
- A second processor does three things. It adds cores, it makes the other eight DIMM slots usable, and it brings up I/O expansion slot 2 — which is often the real reason to fit one.
- The two generations are not interchangeable. First and second generation kits take different memory, and HPE lists a separate configure-to-order base blade for the second generation.
- Watch the enclosure fan count above 135W. HPE calls for 10 fans in a c7000 at that wattage and above, which is a decision about the enclosure rather than the blade.
- Speed Select is a boot-time choice. On the 6240Y and 4214Y, fewer selected cores mean a higher operating frequency, and the setting is prompted for at boot only.

BL460c Gen10 Processors FAQ
Which processors does the BL460c Gen10 support?
Intel Xeon Scalable, first or second generation, one or two per blade on the Intel C621 chipset. Kits listed here run from the six-core Bronze 3104 and 3204 to the 26-core Platinum 8164 and the 24-core Gold 6252 and 6262V.
Can I mix different processors in a BL460c Gen10?
No. Both sockets must carry the same part, so going from one processor to two means a kit identical to the one already fitted.
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 I/O expansion slot 2, which requires a processor in socket 2 and is dead without one.
Which processor gives the best memory speed?
A Platinum 82xx or Gold 62xx part, which runs DDR4 at 2933MT/s. Gold 52xx runs 2666, Silver 42xx runs 2400 and Bronze 32xx runs 2133, and the figure does not change with how many DIMMs are fitted.
What do the Y suffixes on the 6240Y and 4214Y mean?
Intel Speed Select. Those processors can be set at boot through the HPE ROM-based setup utility to one of three core-count and frequency operating points, where selecting fewer cores raises the operating frequency.
Do high-wattage processors need anything from the enclosure?
Yes. HPE calls for 10 fans in a c7000 enclosure when processors of 135W or greater are fitted, so a top-tier Gold or Platinum upgrade is a check on the enclosure as much as on the blade.
