Overclocking Issue i7 4770k & Asus Maximus VI Formula
Need some OC advise!
Hi all,

I currently own a 4 days old :
i7 4770K (FAN: Noctua D14)
Asus Maximus VI Formula (Bios 0804)
Crucial Ballistix Tactical BLT2C8G3D1608ET3LX0CEU (2x8GB)

Trying to do OC results and followed the video on YT by ASUS (http://www.youtube.com/watch?v=Z7zPu9255ZI & http://www.youtube.com/watch?v=4Pilo1E6kXQ)
4.3GHz - 1.185v (Stable 12 hours Prime95 test)
4.4GHz - 1.2-1.3 (Unstable, no bluescreen, but system freezes as soon as i run Prime95 for 2 minutes!)
4.5GHz - 1.25-1.31 (Unstable, system freezes as soon as i run Prime95)

EUFI settings changed for 4.3GHz OC
AI Overclock Tuner -> Manual
Core Ration Limit -> 43
Min CPU Cache Ratio -> 43
Max CPU Cache Ratio -> 43
CPU Core Voltage -> 1.185v

NOT STABLE: EUFI settings changed for 4.4GHz OC
AI Overclock Tuner -> Manual
Core Ration Limit -> 44
Min CPU Cache Ratio -> 44
Max CPU Cache Ratio -> 44
CPU Core Voltage -> 1.2v up to 1.3v

NOT STABLE: EUFI settings changed for 4.5GHz OC
AI Overclock Tuner -> Manual
Core Ration Limit -> 45
Min CPU Cache Ratio -> 45
Max CPU Cache Ratio -> 45
CPU Core Voltage -> 1.25v up to 1.31v

I guess 4.3GHz seems to be the limit, don't wanna go over 1.3v without custom watercooling.
Any advise is welcome!

are you using the AI to OC?

Nope, BIOS only.

when you run the prime, is voltage on manual or adaptive?

well i've seen the video, it was somewhat detailed, but even if you've followed it carefully, do not give up. wait for an expert here to help you, these official videos cannot tell you everything.

EDIT: You are right to have 1.300 volt limit for Vcore. That is also my limit which I will not exceed.

Try reducing the Cache Ratio to 35.
Set Cache Voltage to "Override" mode at 1.18 - 2.00 volts.
Set Vrin also called "CPU Input Voltage" or "Vccin" to 1.9 - 2.1volts.

I also purchased a 4770K about a week ago paired with an ASUS MAXIMUS VI HERO. I've been stuck at 4.3GHz and can not seem to get anything stable at 4.4. Below are my stable 4.3 settings. I think I can get it stable at a lower voltage, but this is where I was messing around. I've tried a core ratio of 44 (1.3v) and cache max of 35 (1.2v) and still can't get it stable. It boots and OS is functional, but AIDA64 blue screens after a few minutes very time. I do change my AI Overclock Tuner to Adaptive once I am done benching. This way it changes the voltage as needed. It runs 28-30C idle this way. That is stable as well.

EUFI STABLE settings:
AI Overclock Tuner -> Manual
Core Ration Limit -> 43
Min CPU Cache Ratio -> AUTO
Max CPU Cache Ratio -> 43
CPU Core Voltage -> 1.250v
Cache Voltage ->AUTO

I've done a lot of reading and Hasewell really seems to be the luck of the draw as it comes to overclocking ability. There are a few YouTube videos out there that have tested the same hardware with different chips and they all clock in differently. One had a batch of 4 that all did 4.3 and others did something between 4.5-4.7. All on the same system. Who knows, if you got yours from Newegg, maybe they were off the same batch or wafer or something. Not to say that really has anything to do with it, but it sounds good in my head.

Thought I would just chime in on this to give my recent account. I am happy at 4.3. Its solid as a rock and I've logged several hours consistently gaming on it with it. I may try and lower my voltage to see if I can run a little cooler. at 4.3 (1.25v) I run AIDA64 around 80-mid 80C, with the occasional peak of 86-87C. Gaming it runs up to maybe 70C or so on BF3 and Tomb Raider. My GPU maintained it's old OC as well with the new board. I came from a 1st gen i7-920 @ 4.0GHz. It seems that this system is squeezing out a few extra FPS, but I wanted to upgrade for other features and just to get on the new platform.

I will mess around with mine some more and share any advances I get since it seems that we are in the same boat.

Hi Jay thanks for the post, can you maybe let me know which settings you disables or enabled in the BIOS before I set your stats for the 4.3 OC?

Really new at this so just want to make sure I enable/disable all the necessary settings. This would all be under "Extreme Tweaker" correct?

Thanks

I literally hit the "set to defaults" then rebooted and went in to make my changes. I really didn't change much at all to achieve 4.3GHz. I think my chip really just doesn't OC all that well so I'm not going to try and drive up the OC because my feeling is it will require a hefty voltage to do that. I was able to get my CPU voltage down to 1.23V from my original 1.25. I did have it stable at 1.225 for a while but after doing some video compression it blue screened, so I ramped it up to 1.23V and haven't had an issue since.

Below are the only changes I made from default. Please keep in mind these are my running settings. When I did my stress testing I changed the mode from Adaptive to Manual with the same voltage. You don't want to stress test on Adaptive because it will allow the voltage to increase over your settings. However, once tested, I set it back to Adaptive so it allows the CPU to reduce the voltage in idle states. Otherwise it would be sucking 1.23V even when it cranks down to 800MHz.

My plan is once I run for a month I might start tweaking my RAM. I've been hammering away at these settings with hours of gaming and such and no crashes yet, so.


AI Overclock Tuner -> XMP
Core Ration Limit -> 43
Max CPU Cache Ratio -> 43
CPU Core Voltage -> Adaptive Mode
Additional Turbo Mode CPU Core Voltage -> 1.230V
