Product overview
This is the Intel Pentium 4 520/521 Processor (prescott, 2.80 GHz, 1MB L2 cache, socket 478), order code SL7E3. In a dual-socket board both sockets have to carry the same model, and the BIOS has to be new enough to recognise it. Send the service tag and we will confirm the firmware revision as well as the chip.
Quotes are itemised down to the accessories, so nothing that is needed to make the part work is left off and discovered later.

What you get ordering this from us
Ordered by part number
Quoted and supplied against SL7E3 specifically, so what arrives is what your build sheet asks for.
Compatibility checked
We confirm the part is supported on your platform before it ships, rather than leaving the check to you.
Answered by a human
A quote comes back with the reasoning attached, including the cases where we think you should buy something else.
Questions buyers ask about this part
Is SL7E3 genuine and is the warranty intact?
Yes. It ships new in Intel 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 SL7E3 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.
