    Rampage 4 Extreme - Bios Downgrade From 4901 to 48xx or 4206

    Hello. I have a nagging question about this bios downgrade. The thing is, I've searched everywhere and I couldn't find the answer. I currently have 4901 bios. I'd like to flash an older bios like 48xx or 4206 as I hear they are better at overclocking 3930K. But how do I go about doing that? What are the exact steps I need to take, should I go back to bios older than 1404 first then update normally with cap converter or should I just write the ERALL.CAP to my old bios and flash away? Thanks.
