i7-5960X mild overclocking

You're not alone benno. I have the SOC Champion and I still haven't found a BIOS file that I like. Some are OK-ish others the 125 strap and XMP are just plain broken. I think you'll likely be in luck with the SOC Force and they'll release a decent BIOS but myself, it almost looks like any support for the Champion is non-existent.
