Product overview
The HPE Xeon Gold 5118 2.3GHz 12 Core synergy 660 G10 CPU is supplied under part number 873387-B21. In a dual-socket board both sockets have to carry the same model, and the BIOS has to be new enough to recognise it. This is the 12-core part. Send the service tag and we will confirm the firmware revision as well as the chip.
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
873387-B21 is what is quoted and 873387-B21 is what ships; where an alternate code is genuinely the same part we name it rather than swap it silently.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
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.
Questions buyers ask about this part
Is 873387-B21 genuine and is the warranty intact?
Yes. Supplied new and unopened, so the manufacturer warranty and firmware update path stay supported. No grey-market stock and no refurbished units sold as new.
Will 873387-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. Purchase orders are accepted from qualified organisations, net terms are available on approval, and tiered pricing applies at quantity. Tell us how many you need.

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.
