P42911-B21 is an HPE Xeon Silver 4316 2.3GHz 20 Core apollo 4200 Gen10 plus CPU. Thermal design power decides the heatsink, and the heatsink decides whether the chassis can take the processor at all. This one runs at 2.3GHz. Tell us the platform and we will quote the cooling that goes with it.

What you get ordering this from us
Ordered by part number
The order is placed against P42911-B21, not against a description of it, so there is no room for a substitution you did not agree to.
No substitutions without asking
If we cannot supply the exact code we tell you what we can supply and why, rather than shipping an equivalent and letting you find out.
Volume pricing
The listed price is per unit; tiered pricing applies at quantity and purchase orders are accepted.
Questions buyers ask about this part
- Is P42911-B21 genuine and is the warranty intact?
- Yes — new and sealed, with the HPE warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will P42911-B21 work in my server?
- Send the service tag. We check the platform's supported-CPU list and the BIOS revision it requires, and where the board is dual-socket we confirm what is in the other socket. A stepping the firmware does not recognise will not post.
- Do you accept purchase orders and quote at volume?
- Yes. We quote against a purchase order and hold the price for the quote period, with tiered rates at quantity. Net terms are available once the account is approved.

Specifying a system, not just the part?
On a training or inference node the host CPU is sized around the accelerators it feeds, not chosen on its own.
