I just decided to measure the real voltage....

Under light load:
Code:

FIXED VOLTAGE --- BIOS READING --- MULTIMETER
1.500 --- 1.480 --- 1.520
1.475 --- 1.456 --- 1.490


Right, seems to be what other people report.

Now to measure it under Prime!

Code:

CPU-Z --- MULTIMETER
1.480 --- !!! 1.563 !!!


IntelBurnTest
Code:
CPU-Z --- MULTIMETER
1.496V-1.512V --- 1.615V-1.620V


I got no words for this, need to get someone to play some BF3 while I measure it aswell, see how far off it shoots in games...

Just decided to make this thread as a word of warning for everyone with this awful Motherboard and propably the Extreme 6 aswell!

EDIT:
Prime running for 15 minutes, Multimeter readings: 1.570-1.572V !!!

EDIT2:
Prime running for 35 minutes, Multimeter readings: 1.581-1.582V...

EDIT3:
Prime running for 1 hour: Still at 1.581-1.582V

Where do I measure it?
Doesn't matter which is positive and which is negative, it will just show a negative number if it is the wrong way around.

lol I always looked at AsRock as a lesser, inferior brand, but others were like "oh no, it's totally quality, why pay more for Asus or Gigabyte"

Laughing Laughing

asrock is garbage. people must be pretty naive to think that asus and gigabyte motherboards cost 2-3x more than asrock for no reason whatsoever. you get what you pay for.

Well this board is the worst board out there at ~140€ price mark.

The previous one I had, P67 Extreme 6, was a frickin epic board, easily one of the best out there but I didn't do my research when it broke down so now I'm stuck with this shitty board with awful MOSFETs and not even remotely accurate VCore reporting :S

Z77 Extreme 6 would have had good MOSFETs but it still has the vcore reading issue that this one does...

My water setup is doing a pretty good job though I reckon, with those readings my max temps are 68/76/76/69 atm Razz

Well that watercooling wont save your 2500K from degradation, that is so high load vcore tbh Very Happy

Yeah obviously, this is mainly intended as a word of warning to everyone else who might even consider this crappy board :l

Measuring again when Prime has ran for 1 hour so in about 5 minutes...

Are you using a properly calibrated multimeter? Who's "reporting" this? I never heard/read of it.

Yes I am, I tested it with 3 different Multimeters to be sure because I wasn't believing it myself at first.

You can find several other reports on interwebs that the Z77 E4 and E6 vcore reading as are off by 0.01-0.03 but that Prime load vcore was nothing I expected, the rest of the readings are "what they should be".

There's something fishy about those values. Mobos regularly are off by a couple percent, but those differences are extreme. Are you sure you didn't use something like auto OC or something (almost all mobos overcompensate Vcore in such cases)? There might even be something wrong with the BIOS (your setting not being logged/saved or something).

It is a known issue with the Z77 Extreme 4 and Extreme 6 but no one has reported it being so extreme under full load.
I'm pretty confident at my overclocking abilities Smile

Just sent email to both AsRock and the shop I bought it from regarding this issue.

Well its not the top of the line, so they probably say "working as intended".

Few more measurements at less VCore and 48x100 multiplier compared to my daily 49x104.1:

Prime
1.472V = 1.555V
1.408V = 1.492V

IBT
1.496V = 1.612V
1.440V = 1.539V

Seems to be the same issue at less VCore.

Also got a reply from the shop I bought it from and first sentence was basicly "You should go read what LLC does."
Very.. friendly.

They also pretty much said it is normal that VCore is not what the motherboard sensor says it is lol
So 0.1V more actual VCore is normal according to them >.<

EDIT: - Stock results:
Prime 1.168 = 1.216
IBT 1.176 = 1.227
