i7 6700k Overclocking issues

When I first entered my BIOS to overclock, I found that the stock core voltage for the CPU was set at 1.30v instead of something like 1.2-1.25v. I didnt want to increase the voltage because it was already set higher than what I wanted it to be (1.27v). I put a multiplier of 45 and restarted and ran Prime95 for stability testing and my comp crashed sending me to blue screen. Does this mean I lost the lottery or can something be done about this? I am willing to increase the voltage to around 3.50v but do not want to strain the CPU too much.

Are you sure that was the CPU Core voltage you were messing with?

3.00v not 1.300v?   3 volts would fry a CPU in no time flat.  Either you are reading the wrong voltage or it is being reported incorrectly.  

Tell my tale to those who ask. Tell it truly; the ill deeds along with the good, and let me be judged accordingly.

did you try using cpuz (cpuid) to confirm the settings for your cpu?

Gigabyte z170x gaming 5, and i am also using the CPUID thats specifically for my mobo type.

hmm, it seems that the new skylakes do come with a higher vcore to start with.

try going into voltage settings and set the llc and pwm phase controll to extreme perf. also try setting the core voltage to 1.32v.

Are you on "AUTO" v core?

Sometimes CPU-Z is really buggy on Z170.

 

Try using HWINFO64, it's way more indepth, and usually more accurate.

hes using a gigabyte mobo, there is no auto vcore only offset.

  1. Make sure to update to the latest Bios. It's still a new tech, compatibility is yet to be fully ironed out.
  2. Before OCing your CPU, make sure your RAM XMP is actually stable, especially if you have a 4 stick kit. Plenty of reports of people having trouble with old "Haswell-E kits" not playing nice with Skylake.
  3. Check the ACTUAL voltage being supplied. Make sure it's not dropping below what you want. Use the LLC setting to adjust it accordingly.
  4. Don't shoot for the moon..... really, it took me 1.3v to get 4.3ghz, you might not get 1.3v 4.5ghz either.
  5. Also, Skylake have higher voltage tolerances than Haswell. The official max is 1.45v, with people saying it's best to stop at 1.4 (and I say you shouldn't cross 1.35, because of heat issues). Take 0.10v out of those numbers and you have Haswell's specs.
