AsRock Z77-series VCore reading!

post #1 of 429
Thread Starter 
EDIT: !!! THIS SEEMS TO APPLY TO ALL ASROCK Z77 SERIES BOARDS !!!

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 TO MEASURE IT?
Doesn't matter which is positive/negative, it will just show a negative number if it is the wrong way around.

Shocking isn't it. I can confirm that my extreme4 and extreme6 do this.

Actually it is lower in games I find. Mine will get 1.51v during intel burn test but only get to 1.38v or so during gaming. i did this playing far cry 3 actually my mother in law did the playing and raided a camp to ensue a firefight while i measured. but yeah vcore was alot lower gaming which is inline with the lower temps i get gaming i guess. I think these processors only use what clockspeed they need and dynamically adjust to load conditions. Correct. Me if I am wrong.

Did you do 12+ hour stability testing at that clock? Because that would be impressive if the extreme4 could handle a sandy chip at 5.1 and nearly 1.6v on an overnight prime. I would then say that your board would be able to handle an IVY pretty easily on air/water. But I would have to recommend they sell it bundled with a free DMM though.
