Overclocking Asrock z77 Extreme6

post #1 of 3
Thread Starter 
I just got my z77 extreme 6 today and got it setup, but I am finding it rather weird to overclock. I have set the multiplier to 44(All Cores) for a starting point, put the vcore(fixed) to 1.35 and enabled PPL while setting LLC to level 5. When I check cpu-z before starting prime I see the voltage hover near 1.35, but upon running prime to put system under load the vcore drops straight down to 1.24 and stays there. I tried upping the voltage, but same thing would happen, under load it would drop down to 1.24 or there abouts. Prime will run for about 15 min then crash. I then tried the built in OC tuner at 4.4 just to see what it would do, and it did the same thing. The difference was instead of bsoding after a bit it would just kill my display. What might be the issue here? Is CPU-z just reading volts wrong? Is there some option that I am not handling correctly?

I have speed step on, hyper threading on, and pretty much setting I have not mentioned on auto/default.

Try putting LLC on level 2 or 1, that should stop voltage from dropping under load.

Interesting it appears Asrock the lower the LLC level the less droop unlike Gigabyte which was the higher level you LLC was the less vdroop. Weird that something like that wouldn't have an industry standard.
