Maximus V Formula vs Fatal1ty Z77 *Higher v-core*  

post #1 of 21
Thread Starter 
Hey guys, i just bought a Maximus V Formula and to my surprise, my 3770k needs more v-core to be stable compared to the Asrock Fatal1ty z77.

Any ideas on how this could be remotely possible?

For reference @ 4.5ghz; The Asrock needed 1.178v
The Maximus Formula needs 1.208v

I'm stumped.... its weird.

Are you using a multimeter to test voltage, or just software? Because software is inaccurate....

Really? hmmm that might be the case then. Very good thinking sir.

Do you think that, even though 2 sometimes 3 different softwares indicate a certain voltage, that it might differ from real voltage?

yea test it out, a lot of companies that don't have vread points on their boards, love to offset vcore readings and have very strong llc that doesn't show.

To some extent you can make the superiIO incorrect. However checking vread points is very interesting, on many gbt boards I have tested, the real voltage is much better than what cpuz reports. Also CPUz is a small program, there are hundreds of different chips to monitor vcore off of, so somtimes they might not be so correct.

Although not the maximus formula, my older asus p67 pro board needed alot more vcore to run a stable 4.8ghz overclock on my 2500k I can do well over 5ghz on my fatal1ty board with the same voltage

check this, these russian guys do good reviews.
http://www.overclockers.ru/lab/49379_4/Obzor_i_testirovanie_materinskoj_platy_ASRock_Fatal1ty_Z77_Performance.html

that is cPUz versus real vcore reading.

Look how big the difference is:

So asrock are sort of cheating? Not trying to start fklame wars but i wanna know if this is the case?
Are they purposely doing this or does it so happen to just be like that..

This could explain why my ASUS max V uses more vcore in CPU-Z ? compared to the Z77 Asrock pro board??
