Product overview
The HPE EPYC 9745 2.4GHz 128 Core socket SP5 Server CPU is supplied under part number P73355-B21. A processor upgrade is constrained by socket, chipset and BIOS revision; this part is 128-core, and a mismatched stepping will not post. We check the platform's supported-CPU list against your service tag before quoting.

Questions buyers ask about this part
- Is P73355-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 P73355-B21 work in my server?
- Send us the server model or service tag and we will confirm before you order. Part numbers alone do not always settle it — firmware revision and platform generation matter, and this is the check that prevents a return.
- 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.
