The board should show the stock voltage at stock clock, then adding +0.1 (same as 0.10 or 0.100) adds 100 millivolts to that value. To add 10mV it would be + 0.01.

+0.1, +0.10, +0.100 and +0.10000000000 are the exact same mathematical values, all that matters is that the "1" is in the same place relative to the decimal place (0.1 for 100mv, 0.01 for 10mv, etc)

So I guess it is not that of a crappy chip, BUT it just won't do 4.5/4.6Ghz with a reasonable vcore. It needs ~1.4 vcore and 2.1 input for 4.5

I have no idea how much it needs for 4.6 propably 1.45vcore. Obviously I haven't pushed it that far because i'm under air. (Thermalright Macho HR-02)

Also for 4.2 it already needs ~1.175-1.2 vcore (haven't tested it enough to be sure)

And for 4.4 already ~1.275 vcore.

What do you guys think is a safe 24/7 vcore? Is 1.275v ok?

Yeah, 1.275v is very safe. I myself had it running for the past 4 months or so, until I got a GPU that stressed my PSU. At which point I had to back down my OC. Oh well.

If you're that close to maxing out a PSU where a couple of hundredths of a volt is making a difference, you'd better get a bigger PSU because you're going to hurt something.

Well, my PC didn't crash at 4.5 with furmark + prime blend, but I did get 124 errors while playing CSGO, which never happened before. So I backed off my OC cuz I'm too lazy to switch to my other PSU at home. Also, the difference is 1.28v vs 1.16v. So more than a coupla hundredths of a volt.

so i think i found out why my pc keeps crashing

mobo seems to think that my uncore and cpu multi are the same

uncores at 4ghz in hwinfo even though i have it set to 3.4ghz in the bios. :/

That happens with Gigabyte boards. Set uncore to 35x. Or you can leave it at 34x and just set uncore voltage to 1.15v

i'll try setting it to 35 and hope it stays at that instead of playing monkey see with my cpu.

sweet, it got the picture. thanks!

You need to set it at something other than default to get it to stay fixed. 34x is default for the 4670K, so set it to 35x instead.
