What to confirm before you buy a used server processor
Server processors are the one component where the model name alone is not enough. Before committing to any supplier, confirm these six points:
- Exact part number and sSpec — the five-character sSpec printed on the heat spreader identifies the production spec, TDP and stepping. The same marketing model can ship under more than one sSpec.
- Socket and platform fit — LGA4189, LGA4677, LGA4710 and LGA1700 are physically different. Dropping a 5th Gen part into a 4th Gen board usually needs a BIOS update first.
- Core count, base clock and TDP — a 205W part will not run in a chassis built for 150W. Confirm the cooling and the power budget of the platform, not just the CPU.
- Memory support — DDR4 against DDR5, and the number of channels, decide the bandwidth per core you actually get.
- Physical condition — no bent pins on LGA pads, no delidding, no corrosion on the IHS, no residue that hides a reflow.
- Warranty in writing — duration, coverage and dead-on-arrival handling. Ours is a 90-day warranty from delivery.

How to choose between core count, clock speed and TDP
- 8 to 16 cores at high clock — best where software is licensed per core (Oracle, SQL Server) or where single-thread latency matters: trading, EDA, small databases.
- 24 to 32 cores — the default for virtualization hosts and general consolidation. Enough cores per socket to absorb a dozen VMs without pinning.
- 48 to 64 cores — for consolidation at scale and memory-bandwidth-bound work such as in-memory databases and simulation. Confirm the platform’s TDP ceiling before choosing.
- TDP headroom — the platform, heatsink and airflow determine what you can install. A higher-core part is not an upgrade if the chassis cannot cool it.
- Memory channels per socket — eight channels on LGA4189, LGA4677 and LGA4710 reward you for populating all of them. Two or four DIMMs per socket leaves bandwidth on the table.
What we check on every used processor
- Pins and pads — LGA lands inspected for bends and contamination before the part is accepted.
- Heat spreader — no delidding marks, no corrosion, no lapping that removes the sSpec etch.
- POST test — each part is installed on a matching platform and must complete POST and report the expected core count, clock and memory configuration.
- Memory channels — all populated channels tested, since a dead channel shows up only under load.
- sSpec photo — the five characters on the heat spreader are photographed on the actual unit and matched to the listing part number.

Xeon families we supply
- E-2400 is the entry-level LGA1700 family for single-socket servers and modest consolidation
- Xeon 6000 and 6500 series are the LGA4710 multi-socket workhorses for data center workloads
- Platinum, Gold and Silver tiers differ in core count and memory capacity rather than in platform
Matching a CPU to the socket and the platform
- The socket must match — LGA1700, LGA4710 and LGA4677 are not interchangeable
- Memory generation follows the platform, so check the supported DDR type and population rules
- Confirm the TDP against your chassis cooling, because a higher-power part changes the thermal design
How we test every CPU before it is listed
- Part number, stepping and core/thread count confirmed against the number you send
- Sustained load testing to confirm stability and that the thermal behaviour is within specification
- The test result and the burn-in record sent with the quote
Why buyers choose used processors
- The cost difference against current-generation parts is largest on older platforms, which is exactly where refresh demand sits
- Multi-socket CPUs are a strong secondary-market fit because the platform is otherwise idle
- The condition of each unit is stated in the quote, and every part is stress-tested before shipment

Frequently Asked Questions
Which Intel Xeon CPUs do you supply?
We stock the E-2400 entry family and the Xeon 6000 and 6500 series multi-socket parts, with other models quoted per part number. Send the model and the quantity and we will confirm what we can allocate, with the condition of each unit stated in the quote.
How do I know which socket my server needs?
Read the socket marking on the board, or check the server model against the platform list. LGA1700 covers the E-2400 generation, LGA4710 the Xeon 6000 and 6500 series, and LGA4677 the 6900 generation. They are not interchangeable, so this is worth confirming before you order.
Are used Xeon CPUs reliable?
Reliability comes from the testing rather than from the age. We clean, re-flash and bench-test every CPU on our own test line, then confirm the part number, stepping, core and thread count and the reported capabilities, and we run the full set under sustained load to confirm stability and in-spec thermal behaviour.
Can I buy a matched pair of CPUs?
Yes, and we recommend it for dual-socket platforms. A matched pair from the same stepping gives predictable memory-channel behaviour and simplifies support. Tell us the model and the quantity and we will confirm what we can allocate in one batch.
What about the warranty on a used processor?
90-day warranty from delivery, on a unit that has been cleaned, re-flashed and stress-tested on our own test line. Batch pricing applies to volume orders, and the test notes go out with the quote.
Will a used Xeon work in a platform that has been out of support?
We state the firmware level each part ships with, so you can confirm the platform still accepts it. Some older platforms have lost microcode support for certain steppings, and that is worth checking with the model before you order.
