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

[BrainY]

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.

I never touched overclocking and was wondering if my system would be able to do this...
CPU: Intel Core i5 4670K Haswell @ 3.40GHz with Noctua NH-D14
MOBO: ASRock Z87 Extreme4
GPU: EVGA GTX 760 SC (2GB)
PSU: OCZ ModXStream Pro 600W

What would you recommend for all the values you wrote above.

BrainY I wouldn't go above any clocking that requires 1.25 volts or more with your CPU cooler. If you want to push any more volts than that, you need to be water cooled

Uhhh a friend told me just to overclock without touching the voltages... what should I change then? Just the CPU Multiplier?

If you overclock without touching voltages your system is going to crash. You need to up voltage a bit for stability. But a NH-D14 can definitely handle more than 1.25V

Overclocking without touching the voltages would mean that you overclock Automatically which is a no go.

Auto Overclocks = Will 100% of the time overvolt your CPU Vcore this will result in too much Heat and is bad for your CPU.

The best way is manually set the voltages for your Vcore, input voltage, cache voltage and the multipliers. Check the guide on this thread first page, post #1.

As for NHD14 I am sure it can cool off 1.25 volts. My Cryorig R1 Ultimate easily cooled my old 4670K running at 4.6 GHz manual OC @1.262 volts. With very good temperatures 28 degree idle not going over 61 at full tilt.

But ye, never auto OC, always go for Manual OC its the best thing yet. Even the turbo boost the Intel chip does uses bad voltages, they put more volts than is needed.

I appreciate your input. So basically do whatever IntelGod tells you to do? :-D What if I want to run at 4.0 Ghz or you think I should just go with the 4.4 Ghz anyway? 😀

I got my i5 4670k to 4.2ghz with 1.112 voltage. Is that not pretty good? What voltage should I try first for 4.4ghz or 4.6ghz.

P.S I have set my voltage to dynamic. I think I set it to 1.080 and it upped it for me presumably to keep it stable.

Tetsuya23 You got a pic of the litter chip getting 4.6ghz with 1.26 volts. It took 3.5 volts for me to push a stable 4.6ghz OC. I know its higher voltage than I like, but my temps are good, idle at mid to high 20s and mid to high 70s under a burn test

Help me?

[airplanegeek]

There is no way to push 3.5V the chip would've instantly died

 

[Bigj73nsb]

Lol my bad I meant 1.35 volts

 

[cingelj16]

Hello, not sure if you are still answering questions but I am unable to get to 4.4 with my 4670k. Here is a lint to my thread if you could help.

Can someone give me some advice on fine-tuning my overclock.
AsRock Extreme 4 Z87. I7 4770k. Dark Rock Pro 3 Cooler (Thermal Paste reapplied yesterday)

I have it running stable according to Intel Burn Test (10 runs), settings 4.4GHz, VCore 1.25v, Cache 1.20v, CPU Input 1.9v, LLC 2. Max Temps 83c 80c 76c 73c.
My issue, is that the speed I was getting was 100GFlops to 89GFlops.

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.

I wanted to do this because I bought this system piece mail in 13. Ive had it for 2 years and games like CoD Blops 3 are more demanding. So instead of sinking more money into more hardware I figured i should try OC. I have the intel i7-4770k on an msi z87-g45 board. I noticed there was a button called "OC Genie". I read that it was a "1 sec overlclock." I didnt believe it but tried it. With one button i made the 3.5 into a 4.0. I was happy and noticed a little faster response. However after about an hour of this...i got a zzzzzzt sound followed by the infamous BSOD!

Naturally I went in the bios and turned that thing off and its been fine since. I read that manual oc is the way to go so here I am. I was wanting to try this but I dont want to melt my only form of something to do around here. Thing to consider which I didnt see :

1. I have the cooler master case as in this pic. http://gaming.coolermaster.com/images/products/33/image_620.jpg
2. There are no custom heat sinks except what came with the cpu and board. Stock sinks.
3. How dangerous is YOUR particular setup?
4. Im assuming I should have a backup plan incase stability is an issue and..
5. My machine bsod at 4.0. This guide takes it up to 4.4. Isnt that even worse and more risky for me?
6. When you list what to do, does one assume to "leave every other setting in there on whatever it was?" or....

Thanks,
VAM

PS : Forgive my impudence intel god! I know not what I do!

I've tried a few days to get my 4670k to at least 4.4 but it simply won't.

I was at 1.3vcore

2v input and the highest you set for cache and Nope it won't even start Windows. Do I have a bad chip? Someone wants to help me?

 

[firecotton]

I have a Gigabyte Z87X-UD3H motherboard with a 4670k and I can't for the life of me find some of these settings. I'm probably just blind because I'm new at this, but can anyone with the same motherboard help me out?

All I did was change the "CPU Clock Ratio" to 44 and "CPU Vcore to 1.220v".

I also left Uncore Voltage at stock which was 3.4ghz. I read that you also need to put that to the same value that you changed or a little bit lower, but I'm not sure if that's right or not.

I also don't know where the fixed setting is, I think my CPU is set to adaptive since it jumps up and down in AIDA64. Whenever I do the stress test it goes up to 4.4ghz like I want to.
