On asrock z87 matx and atx form factor should work at 2666 tight with +0.01 Sa ,+0.01 Ioa and +0.02 Iod. Sometimes when you push for more frequency on cpu SA needs to be lifted as well.
Where i can see stock voltages values for imc on asrock ?
If,for example i put +0.01 on SA the voltage will be ?
Ps:don't leave on auto,the values which are set are crazy, sa= +300 ,ioa= + 250 and iod = + 200.
