Intel God's "Quick & Dirty" OC Guide to 4.4Ghz with Haswell

[Intel God]

Put this together for the new guys who want a quick and dirty way to 4.4Ghz. I used 4.4Ghz because that's the speed almost everyone should be able to hit with a Hyper 212+ EVO.

First things to change in the Bios. Make sure you are on your newest bios before overclocking.

1. Set "All Core" CPU Multiplier to 44X
2. Set CPU cache Multiplier also called the Ring bus multiplier to 35
3. Set Fixed CPU Vcore to 1.25 -1.30v
4. Set CPU Cache Voltage also could be called Ring Bus voltage to 1.20v -1.25vv
5. Set Vrin also called "CPU Input Voltage" To 1.9v - 2.1v

DO NOT and i repeat DO NOT mix up the "Cpu Voltage" and the "CPU Input Voltage". One is for the CPU and the other for the On Die VRM's.

Save and reboot into windows.
Use your favorite Stress tool. I used IBT on High and monitor temps with Realtemp or some other monitoring program.
Run it for 10 Runs or 20 or whoever you feel comfortable with. I run it for 10 usually. If it doesn't blue screen you after the 5th run you could assume you're stable. Again run it for as many times as you want. Get through 10 or 20 runs and no crash? Congratulations you're stable and you can fine tune.





I couldn't get a clear Bios picture for you all so this is the next best thing.





Some extra's. Some bios' will add in a little offset voltage for both the CPU and Cache. Mine was .8 for the CPU and .4 for the Cache. If that happens put the lowest setting you can. Not "Auto" but .01 for each. My ASRock board did but i don't know if yours will. Any questions please post in here and i will answer.

Oh, make it a dirty sticky.

 

[Som3one]

And give a dirty name. lol
Oh..wait...already got one.


Quick question: So, you prefer fixed vcore over offset/adaptive?

You dont want to use adaptive because most of the time it'll push vcore way too high. The fixed voltage is the best way to keep temps and volts in check

Thank you

 

[Intel God]

Thank you

It work good for you Steve?

 

[stevems]

Thank you

It work good for you Steve?

Yes, really good. I am able to run through through demanding programs without the cpu crashing.

Not working over here...unfortunately.
Getting a blue screen after 2mins of Prime.

How are temps? Try upping the cache voltage to 1.15v. 1.10v might be too low for some chips. I will revise the OP

 

[Som3one]

Average at around 69°C, hitting 74°C from time to time with a Kraken x60.


EDIT: Temps while using Prime of course.

Those temps are super safe. Did upping the cache voltage help with stability?

 

[Som3one]

Will check it out lateron...or tomorrow.

Didnt work for me. BSOD while loading Windows. I also tried:

CPU Vcore 1.3
CPU Cache Voltage 1.2
CPU Input Voltage 2.1

Same result - BSOD while loading Windows. Im on the Asrock Z87E-ITX-board.

 

[Christian Angelo]

I also tried this with the Asrock Z87E-ITX board and a 4670k and had to ramp the CPU vcore to 1.3, and the CPU cache to 1.2 to get it to not bsod 124. This had it working but I was reaching temperatures 80C+ on prime with aircooling (Corsair A70).

I find this relatively odd since I normally run at 4.2 vcore:1.15 cache: 3.9, voltage:1.1 and it works without a hitch.

It seems like an awfully large jump in voltage for me for 200MHz more.

 

[Som3one]

Yeah, I guess every chip as such a jump somewhere. Especially with Haswell.

Linus from LinusTechTips suggests to put everything to Auto, then set the VCore to 1.25 and the multi to 46.
This is to get an idea of the overclockability of a specific chip, depending how it reacts to those settings.

Thank you both for the input. I will modify the OP to show there is some play needed in the voltages.

 

[limoncifi]

anyone know where can i set the offset values on asus boards?

 

[Som3one]

Under AITweaker. Then set the according value from "Auto" to "Offset".

Hi Intel GOD. Could you please take a look at my BIOS to which settings to change? Thanks

John what issues are you having? Crash? Freeze? Try pushing up the CPU input voltage to 1.9v

John what issues are you having? Crash? Freeze? Try pushing up the CPU input voltage to 1.9v

When I was running 4.3Ghz with 1.3vcore, AIDA64 Runs for 20minutes no problem. But when I tried Intelburntest, right when I run the test it BSOD. Right now, I'm currently running @4.2Ghz with 1.25vcore and it passed 20 runs of intel burn test on high but the temps are scary lol the hottest it went is 91C but the average is around 75-85C 100% Load. When I try to change the CPU Input Voltage to 1.9v the letter becomes RED. Should I still continue to make it 1.9v? Thanks

UPDATE: Tried 4.3Ghz with 1.3vcore and 2.0v input voltage, ran IBT High 5 runs and the temps is around 90-98C! I don't know if my cpu is really that bad or is there something wrong with my cooler. Kraken X60 should have better temps than 212 EVO.

2.0-2.1v is the max you want to set the CIV on air. What cooler are you using?

NZXT Kraken X60. I went back to 4.2Ghz with 1.25vcore and here's a quick IBT Test result. I don't know if 115Gflops is normal for a 4.2Ghz overclock. Seems a bit low to me compared to the 124Gflops you got.

*UPDATE* ran IBT on very high and got 120Gflops.

 

[Som3one]

Unfortunately not.
Got a reboot after about 2mins running Prime.

My run was with 2666 memory and core parking is disabled. Have you disabled it? If not give it a shot
