CPU 4.4GHz overclock

[cheekboys]

Can someone give me a very simple guide to overclocking my CPU to 4.4 GHz? I don't need one that goes into extreme detail. I have an Intel core i5 4670K and a Cooler Master Hyper 212 evo.

Linus tech tips haswell Overclocking guide look it up on youtube best tutorial ever!!!

[Cloud92]

google is your friend. Might wanna specify what's your CPU and motherboard as well as cooler you know..

[Keudn]

Well what is your motherboard and CPU? You have to make sure you can overclock on them first

You can't go into overclocking with a goal when you use a Haswell processor.  Go into your overclock with an open mind.  Your results are going to be completely unique to the chip that you have, don't try and replicate other people's results.  Overclocking is a long process when done right, and you need to be patient.  Start low and work your way up.

 

Here are some of the best guides available on the internet:

When stress testing, set voltage to manual/constant, not adaptive.

Put multiplier to 44, stress test, add voltage until stable.

Nobody can guarantee 4.4GHz overclocks with Haswell CPUs. You will get 4.2 stable most likely. Everything over that is good.

I have tried setting the voltage to as much as 3.6 and I still get BSOD on Watch_Dogs and Assassin's Creed 4 but not on Far Cry 3. Could a certain game cause a BSOD even when others don't? My temps are  65-75C.

Also is there a guide that uses a Gigabyte Z87X-UD3H Dualbios?

Umm... Dualbios is default in UD3H. You have to switch jacks to switch to secondary or to single. I highly doubt you have voltage at 3.6. That would kill your CPU. Maxinum voltage for Haswell is 1.4V and that is only if you have really good cooling. So try setting multiplier to 37-39 and voltage to 1.15-1.2V. If you are still getting BSODs or crashes during stress testing, you have bad chip and there's little you can do about it via BIOS.

Here's the simplest guide for overclocking to 4.4GHz:

 

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. 

 

 

 

 

 

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.

Sorry! I meant 1.36. I think I have a stable OC now at 1.34 voltage at 4.4GHz using this guide http://www.overclock.net/t/1401976/the-gigabyte-z87-haswell-overclocking-oc-guide

Thats pretty high voltage. Do your temps stay down during stress testing?

During stress I get around 85-90 but during gameplay I get around 65-70 on Watch Dogs which is a CPU heavy game.

I'd call that too high temps under stress. But its your choise.

I might try a lower voltage but it will most likely BSOD. Are those temps safe in gameplay If it never goes above 75?

Sure. Just saying that if you lose your cpu because of running it with too high voltages, you have been warned. 212 Evo, though being great little cooler, isn't miracle maker.

You should be able to hit 4.4GHz at 1.25 -1.30v. If you look above I posted a quick 4.4GHz overclock guide. Double check your settings and see if they coincide with the guide I posted.

 

For gameplay yes 75C is fine but realistically you want to try to get below 80C during stress tests too.

On my motherboard there is no cpu cache multiplier. It is a Z87X UD3H.

It probably has another name, I'm sure it has to be outlined somewhere in this thread: http://www.overclock.net/t/1401976/the-gigabyte-z87-haswell-overclocking-oc-guide

How much would the cache multiplier affect the stability? I think it is the uncore clock.

[SpecTre12345]

I think you are right about it being uncore. Supposedly it does effect stability to some extent.

[Faa]

Well the cache ratio doesn't matter, there's just no difference.



The 4.2 vs 3.4 is the uncore setting. The core multiplier for this test was x45.

I mean overclock stability not performance.
