I was looking at guides to overclock my i5 6500 and they say to put voltage at 1.325V. My defaullt is 1.12V, so isnt 1.325 a bit high.

I did run Prime95 for an hour at my overclocked settings and it didnt crash, but still worried since with thse beta bios the temps are not reported correctly.

Max voltage is 1.5 volts (per Intel)..

If 1.325V is stable, great but you don't stop there....

Start lowering the voltage in very small increments and stress testing to see if that's really the min voltage that makes your chip stable.

Safe voltage is always a relative question... Relative to your chip, cooler, how long you want it to keep running etc..

I see people saying 1.4 v on Skylake is ok, but personally I'm running right around 1.325 (Which I need for stability)

I bought the Intel protection plan for mine. All voltages are "safe" ;)

EDIT: But seriously, don't go above 1.45v.

Asus recommend 1.45v max unless you are doing heavy FMA3/AVX loads like prime95 in which case 1.42v.

I'm not sure if this is because a voltage set to 1.42v will rise to near 1.45v under prime load, or if that kind of load will induce a current that might be too much at voltages above 1.42v.

After testing a bunch, 1.325 seems to be the best for the speed I am getting. I tried 1.3 and Prime95 failed after 10 minutes. At 1.35V, I could squeeze maybe 1Mhz increase in bclk but dont think its worth it.

I know that on my G4400 and Z170 Pro4S board, it shows 1.400V in red, when I select it, but 1.3800V is in green. But my G4400 won't be fully stable under BOINC load at 4.5Ghz @ 1.380V. So I'm running at 4.125V @ 1.200V. I could run at 4.29Ghz @ 1.300V though.
