Product overview
Part number 864640-001 identifies this HPE Xeon E5-2620 v4 2.1GHz 8 Core Z640 workstation CPU. Licensing is often counted per core, so the cheapest chip that fits the socket is not always the cheapest chip to run. This part is 8-core. Tell us what the host is licensed for and we will factor that into the recommendation.
Priced per unit, with tiered pricing at quantity — send the number you need and we will come back with the banded price.

What you get ordering this from us
Ordered by part number
Quoted and supplied against 864640-001 specifically, so what arrives is what your build sheet asks for.
BIOS revision checked
We confirm the firmware level the platform needs to recognise this processor, because a chip the BIOS does not know will not post.
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 864640-001 genuine and is the warranty intact?
- Yes. It ships new in HPE packaging, which is what keeps the warranty and the firmware entitlement valid. Anything we cannot supply that way we tell you about before you order.
- Will 864640-001 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 — POs from qualified organisations, net terms on approval, and banded pricing once the quantity is worth banding. Send the number and we will price it properly.

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.
