Hi, I recently picked up an X99 UD4 and paired it with a 5820k. I initially had issues with booting up with the F7 bios, so I updated to BIOS F8b posted on the Gigabyte website, and all was good. However, when I try to OC in the UEFI/bios changing any CPU setting like multiplier, turbo boost, voltage, etc, causes it to fail to boot and it will give me the 'boot failure' message, prompting me to load the defaults. Even if its only a 100 mhz increase or merely disabling intel turbo boost.
I am able to use the Gigabyte EZTune to OC to 4.2 ghz using the 'extreme' setting without issues in Windows, but changing any CPU settings in BIOS presents a problem. What gives, is this just an issue with the beta bios? Also, in EZTune, the 'Advanced CPU OC' section does not give me any options to change the OC, just an empty panel. Not sure what thats about.
