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.
