HP Refurbished Processors
We stock refurbished HP and Hewlett Packard Enterprise processors for ProLiant servers, from legacy G6 and G7 systems through Gen11. The range covers Intel Xeon across Platinum, Gold, Silver, and Bronze tiers, and AMD EPYC for HPE's AMD-based servers. Whether you're replacing a failed HP server CPU, adding a second processor, or upgrading to a higher core count, we have refurbished HP processors ready to ship. If you need a model that isn't listed, our team can often source it.
Every refurbished processor is inspected and tested before shipping under our ISO 9001-certified quality management system. Orders ship from our warehouse in Denmark — with express delivery, your order will be delivered within 1–2 working days.

- Intel Xeon and AMD EPYC processors for ProLiant G6 through Gen11
Refurbished HP CPUs for ProLiant Gen10, Gen10 Plus, and Gen11
Each recent ProLiant generation uses a different processor platform and socket. Gen10 servers use first- and second-generation Intel Xeon Scalable processors on LGA 3647. Gen10 Plus moves to third-generation Xeon Scalable on LGA 4189, while AMD models such as the DL325 and DL385 use EPYC 7002 and 7003 series processors.
Gen11 uses fourth- and fifth-generation Xeon Scalable on LGA 4677, or AMD EPYC 9004 series. We stock all of these across Platinum, Gold, Silver, and Bronze tiers, so you can match core count and TDP to your workload and cooling capacity. For a guide to reading EPYC model numbers, see our AMD CPU naming guide.
Refurbished HP Processors for ProLiant Gen8 and Gen9
Gen8 and Gen9 servers remain widely deployed, and refurbished processors are a cost-effective way to extend their life. Gen8 uses Intel Xeon E5-2600 and E5-2600 v2 processors on LGA 2011. Gen9 uses E5-2600 v3 and v4 on LGA 2011-3. Upgrading a Gen9 server from v3 to v4 processors can add cores without changing platforms, provided the server is running a compatible system ROM version.
Legacy HP Processors for ProLiant G6 and G7
For older ProLiant G6 and G7 servers, we stock refurbished Intel Xeon 5500 and 5600 series processors on LGA 1366. These platforms are long past end of sale, and refurbished processors are often the only practical way to repair or upgrade them while keeping legacy applications running.
HPE CPU Kits, Part Numbers, and Heatsinks
HPE sells processors as option kits with -B21 or -L21 suffixes. Kits for the same CPU can differ depending on the server model and socket position they're intended for, and some include a heatsink. The spare part number ending in -001 identifies the processor itself.
When adding a second CPU, check whether your server needs a matching heatsink and, on some models, additional fans or memory for the second socket. Search by any of these numbers in our Parts Finder, or use our Server Configurator to build a ProLiant configuration with compatible processors.
Frequently Asked Questions
Which HP processor fits my ProLiant server? It depends on the generation: Xeon 5500/5600 for G6 and G7, Xeon E5-2600 (v1–v4) for Gen8 and Gen9, Xeon Scalable or AMD EPYC for Gen10 and later. Search your server model or CPU part number in our Parts Finder, or contact our team.
What's the difference between HPE -B21, -L21, and -001 processor part numbers? The -B21 and -L21 numbers are option kit numbers, which can vary by server and socket position and may include a heatsink. The -001 number is the spare part number of the processor itself.
Can I mix different processors in a dual-socket HP server? No. Both sockets must use identical processors, with the same model, stepping, and speed.
How much does a refurbished HP CPU cost? Prices are listed on each product and depend on generation, tier, and core count. Refurbished HP processors typically cost up to 80% less than new.
What's the warranty on a refurbished HP processor? Every refurbished HP processor comes with a 1-year warranty.
