I have 2 issues with this board that need resolving.
It seems this board like others from gigabytes z77 range are having BCLK sync stability issues.
My board seems to only stabilise when locked to 100.06Mhz via easytune. Compared to its standard BLCK (100.1) its alot smoother though still not perfect. (100.06 set via the bios = 100.32 reported by easytune in win)
I'm requesting official BIOS fix for these problems.
Also im having issues installing the driver for the iGPU on the ivy, it locks up with a 7e BSOD when the driver is being installed.
