I did try it with gaming. But only in Far Cry 3, I had my mother in law hold "w" and run through a raider camp to get shot at by everyone. My CPU was clocked at 5 ghz with a max vcore by IBT of 1.51v measure dby digital multimeter. I found that far cry 3 only used about 1.35v-1.38v and never crossed 1.4v. I don't think these chips use their full clockspeed while gaming, unless it is because I use turbo offset for overclocking, not sure really. But the lower voltage used is inline with the lower temps you would get from gaming when compared to IBT.

Is there a program that will show your current clockspeed "always on top" while gaming and be accurate about it?

You can use HWinfo in combination with Afterburner or EVGA Precision for CPU load/frequency.

idk if the X79 E11 has the same issues. but it might, as i don't see a review of the caliber which would test real versus software readings. Only site i know that does it every board is overclockers.ru, and even then it is only certain reviewers who do this. Then hardware canucks does it but they have like no reviews lol.

THe X79 extreme11 was the latest X79 boards released by ASRock and it had its vrm changed from a 16 phase digital to a 24 phase analog. You can check the news about this change, it is about the same time Z77 was released and when asus announced it was selling its 24% share of asrock. That digital PWM that asrock used the CHL8328 was only made for asus boards, under an exclusivity contract, but when IR bought CHil everyone else could use it, but you have to get a contract with IR which you just don't do overnight. I am pretty sure asrock wont use this same pwm on Z87, if not only because they are using a analog pwm and marketing it as digital and because i said something about it.

See the issue is the way the Intersil PWM handles LLC, and it can be changed of course even with a BIOS update, something to update the GPIO to tell the PWM how to do LLC, as the intersil PWM is analog, it can't be programmed directly to control LLC, it relies on a separate chip(GPIO) to handle it. THe E4 and E6 use different most everything in the power conversion stage(driver and MOSFETs are very different on both boards) yet they seem to still have the same issue, and that would be the PWM making that issue, as the Z77 OC Formula doesn't have this issue, but it also doesn't use the intersil PWM.

Shameful on asrock's part.
Guilty here. Bought mine when they 1st came out last April/May I think.

Thanks it works! Saints row 3 apparently pushes a 3570k to about 85% on all 4 cores when clocked to 4.9ghz.. Cpu hungry Console port? Yes it seems to report being clocked to 4.9 the whole time gaming. There goes my theory about the chip using a lowered clock speed.

If you OC your chip and use 1.20 Vcore. When you than measure it it turns out to be 1.30 Vcore. But your chip is stable at lets say 4.2 GHz. And at 1.19V (When measuring 1.29V) it BSODS/Crashes. That cant be true, because users with other boards will crash as well with 1.19 Vcore at 4.2 GHZ. But you, as a Extreme 4 users shouldnt crash because you are measuring 1.29V which would be too high volts for that clock.

This is just an example and I hope you guys get it since English is not my native language and this is difficult to explain, im also not experienced with electrical things.

I actually noticed this first hand when I got my board, I required a lot less VCore (in reality it wasn't any less) to achieve same overclock as I did on my previous board (P67 Extreme 6).

So this issue definitely wasn't present on the P67 E6 atleast.

Jizus. I can't believe this :-(.
Could the Z68 extreme4 gen3 be affected like this as well?
cheers.

I am 99.99% sure that Z68 Extreme4 doesn't have that issue. It's a very nice board unlike Z77 Extreme4.
