Product overview
HP lists 455423-B21 as an Xeon E5430 socket LGA771 2.66GHz 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.
Ask for the datasheet and firmware notes with the quote; we would rather you check our claim than take it.

Questions buyers ask about this part
- Is 455423-B21 genuine and is the warranty intact?
- Yes. It ships new in HP 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 455423-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 — 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.
