it is not a Microcode issue. but gigabyte made some improvement in the last revisions of all motherboards.
i don't know. i asked my supplier of cpu for compatibility 8222CL on a C621-WD12. i have to wait for the reply.rev 1.0. I can see on Gigabyte website there was no another revisions. Is that correct?
ok good and bad. my chineese supplier told me latest BIOS should work. i have to ask again. can take some time.
there is a table inside the VRM controller chip.Do you mean VRM controller firmware upgrade? Ok but if I tell them that I'm trying to run 8222CL CPU they will probably say that is not supported CPU.
