I tried out several bios to be able to set bclk higher, some wouldn't even enable turbo clocks.
But turbo really works only if forced with the Throttlestop software in the OS in my case:

It's even stable at 114.3 mhz so far (still testing for everyday use)
I use HyperX Genesis 1600C9 DDR3 sticks which are nothing fancy.
Just had to set their speed down one notch to get there.
Maybe you should set your RAM to lower clocks too and see if that allows you to
go higher on bclk.
Thanks for the support and good luck
