Gigabyte Z390 Aorus Master
WHY WE CHOSE IT
"We picked the board for the VRM and kept it for the BIOS. It sits on the same Z390 Aorus BIOS tree as the rest of the family, so the menu paths, the LLC naming and the voltage entries in our BIOS guide land where this page says they land."
A 12+2 phase IR digital VRM, the circuit that turns 12V into the voltage the CPU core actually sees, running IR3553 40A power stages. Gigabyte cools it with a Fins-Array heatsink over a direct-touch heatpipe. Three M.2 slots sit under thermal guards and six SATA III ports carry the four-drive array.

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.
