Product overview
This is the HP X5355 socket LGA771 2.66GHz 4-Core Processor, order code 436015-L21. Thermal design power decides the heatsink, and the heatsink decides whether the chassis can take the processor at all. This one runs at 2.66GHz. Tell us the platform and we will quote the cooling that goes with it.
Tell us the deadline you are working to and we will say whether it is achievable before you commit to it internally.

What you get ordering this from us
Ordered by part number
The order is placed against 436015-L21, not against a description of it, so there is no room for a substitution you did not agree to.
Matched pairs for dual-socket
Where both sockets have to carry the same model we quote the pair, not the single chip.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Questions buyers ask about this part
- Is 436015-L21 genuine and is the warranty intact?
- Yes — new and sealed, with the HP warranty and the firmware update path intact. We do not sell refurbished stock as new, and we do not source grey-market units.
- Will 436015-L21 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.
