From yesterday to today, I learned some things about MSI Z170-A PRO
First, clear cmos up! .
After updating the unlocked bios, I changed BCLK, saved and nothing happened
Once you clear up CMOS, the multiplier went to work.
Some combinations of settings can break the overclocking and BIOS reset.
If this happens, clear up CMOS.
Second, Set the Extreme Memory Profile (XMP)
Reboot and instability.
I put off.
Third, Change the CPU Ratio to 37, Change the Ring ratio to 37
These two related options, cause a strange effect, in which you view the change in bclk, but it set the clock in 3.7
keep in auto, real change clock.
Four Set the CPU Core Voltage to 1325
this voltage suits well to overclocking Skylake the problem and that some mortherboards station not showing the voltage correctly.
IN my case I put 1,325 self in CPUZ and bios showed 1,432. So I put vcore m 1,240 Override + Fixed 0005, now appeared properly 1336.
if some friends have a problem with high vcore, try switching to low
I've been testing several numbers for bclk, memory and vcore. But my Prime95 blend test with 4.5GHz and ram 3091 freeze the PC, I have good memories corsair LPX 3200, does not seem to be the issue.
I'm currently using the configuration of der8auer and DigitalFoundry, Core i3 4.4GHz BCLK 6100 / 2560mhz, this more balanced.
