Intel Core i9-9900K
WHY WE CHOSE IT
"A synchronized 5.0GHz all-core clock is what our BIOS guide targets, with the ring ratio at 47 and a static Vcore. The rest of the build is tuned around that number."
Eight cores and sixteen threads on Coffee Lake Refresh, 3.60 GHz base and a 5.00 GHz boost, 16MB of L3 and a 95W TDP rating. This is the top of Intel's 14nm desktop line.

Component Procurement & Testing FAQs
Crucial advice on buying used enthusiast PC hardware, silicon binning, and thermal maintenance.
Silicon degradation manifests as instability at stock or mild voltages. Test the CPU by running OCCT CPU / Linpack at stock voltage; if errors occur within 10 minutes, the silicon has experienced degradation.
For used graphics cards (especially OEM or previously mined units), check VRAM junction temperatures and inspect HWInfo64 for "PCIe Bus Errors" (WHEA 17/19).
Replacing dried thermal pads and applying PTM7950 to the GPU core restores used hardware to factory thermal performance.
Always check WHEA errors in HWInfo64 and verify voltage stability on second-hand hardware.
