With these X99 GIGABYTE boards, you should really only use the classic mode (gray BIOS) by pressing F2 when you are greeted by the very basic mode upon entrance into the UEFI. From the classic mode, you can access all the settings, including overclocking. While I only have access to the F1 BIOS, the first release for the X99-SLI, everything worked very well.
Bugs from first wave GIGABYTE X99 motherboards, such as the rebooting that occurred with certain USB drives plugged in have been solved, and the UEFI performs better than one would expect from a $250 product (as long as you use classic mode BIOS).
Overall, I was impressed by the maturity of this first release UEFI. I do, however, wish that GIGABYTE would expand fan control, perhaps provide a GUI. When you enable the CPU mode switch, 6 extra voltages become available under the CPU voltage menu.
Only VL4, 5, and 6 should be increased. First start off with 1.44 or 1.45v on VL6 for cache overclocking. VLs will increase by auto rules, so you might not have to change them at all.
EasyTune is the go to program for most novice overclockers and it presents a decent amount of tuning options and monitoring. GIGABYTE also provides other programs through the APP center such as @BIOS, Ambient LED, Cloud Station, Smart Recovery 2, Fast Boot, Smart TimeLock, and SIV.
For more advanced overclockers, GIGABYTE Tweak Launcher (GTL) is much simpler and better.
