Product overview
Part number 437940-B21 identifies this HP Xeon E5345 LGA771 2.33GHz 4-Core Processor. A processor upgrade is constrained by socket, chipset and BIOS revision, and a mismatched stepping will not post. This part is 4-core. We check the platform's supported-CPU list against your service tag before quoting.
Send the service tag and we will check the BIOS level the platform needs for this processor before you buy it.

What you get ordering this from us
Ordered by part number
Quoted and supplied against 437940-B21 specifically, so what arrives is what your build sheet asks for.
Matched pairs for dual-socket
Where both sockets have to carry the same model we quote the pair, not the single chip.
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 437940-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 437940-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.
