rigvelaCPU, motherboard, and BIOS: check before you buy
Installing a CPU requires a matching socket, support for the exact processor and a suitable BIOS version. Here is how to find those details and check whether a firmware update is possible before replacing the CPU.

Find the exact support page
Copy the complete motherboard name from its label or packaging, including suffixes and any hardware revision. Similar Wi-Fi, memory-type, or revision variants can have different support pages. Open the motherboard manufacturer’s website and find the CPU support list for that exact board.
Locate the full CPU model in the list. If it is absent, do not infer support from the socket or chipset name alone. Ask the manufacturer or choose a documented combination. A shop’s statement that a board supports a processor generation does not establish which firmware a particular unit contains.
Compare required and installed firmware
Look up the BIOS version listed for the processor, then establish what the board actually has. On a working PC, inspect the UEFI/BIOS information screen. For an unopened board, ask the seller to confirm its firmware or offer preparation for your chosen CPU.
Read the release notes and update sequence for that board. Buying recently does not prove that a unit has recent firmware; stock can be older. If the installed version is unknown, record a BIOS check as unresolved instead of treating the combination as unconditionally ready.
Make sure an update is practical
If the old supported CPU is still installed and the PC works, establish the manufacturer’s update method before replacing it. Without a working CPU, check whether this specific board has a firmware-update function that does not require entering the normal BIOS interface. A USB port by itself does not establish that capability.
Features such as USB BIOS FlashBack have model-specific requirements for the file, port, USB drive, and power. Follow the board manual, use firmware for the exact model, and do not interrupt an update in progress. If no suitable route exists, arrange a seller or service update beforehand and include its cost.
Record the BIOS versions and update method
Select the CPU and board in RigVela and mark a board you are keeping as owned. Record the installed BIOS, the required version and the update method alongside the parts list. Get those details from your PC and its documentation; the builder cannot read its firmware.
Quick checklist
- Match the exact motherboard model and revision.
- Confirm the CPU entry and installed BIOS version.
- If updating is required, arrange a valid method before buying.
Check your exact CPU and motherboard
Choose a CPU and board from the catalogue to compare socket and CPU-family support. Check the installed BIOS version separately.
