Weird VCCIO/VCCSA

post #1 of 4
Thread Starter 
Hey, I am kind of new to overclocking and I was trying to change the VCCIO/VCCSA, I tired using 1.2 and 1.225. But when I reload the BIOS to check if they're set they're completely way off too what I set them too...?

For example if I set the VCCSA to 1.225 it would be like 1.27 or the VCCIO I set to 1.2 it would be like 1.8... I am totally confused on why this is happening. Anyone got any clues?

Specs:

i7 7700k with Kraken x62
GTX 1080 Ti
Trident Z RGB 3200mhz ram
ASUS Z270f @ lastest bios 0906

That's just the way your board handles those voltages. Mine (ASUS Maximus VIII Gene) does the same thing. You'll have to adjust the values you put in downward to get the actual voltages you want.

Thank you for replying. I also have another question if you can answer please? Is it normal for say an overclock of 4.9ghz to drop to like 4,896.4 sometimes? or is there something wrong with my OC and does it make any kind of difference in performance?

That's just the BCLK fluctuating a bit (maybe going down to 99.9 or 99.8), and it's normal. It might even go a bit higher than 4.9GHz too (BCLK 100.1 or so). I set my BCLK to 101 so that it never goes below 100.
