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

[Som3one]

Looks like it. Funny thing, it´s my second chip and I bet my first one would have been better. :-/

Hi Intel GOD. Could you please take a look at my BIOS to which settings to change? Thanks
Here's the link for the pictures: https://copy.com/gsJEgAWI6w3M

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

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.

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

http://forum.cakewalk.com/tm.aspx?m=1861804

Did upping the cache voltage help with stability?

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

Christ you have a finicky chip

I have windows 8. Anyway, I think I'll just stick with 4.2Ghz for now. Is there any huge noticeable difference between 4.2 and 4.4Ghz? And I have a 1600Mhz memory, Is it possible to overclock it to lets say 2133Mhz and at what voltage without killing it? Also, What do you think of this software - http://bitsum.com/about_cpu_core_parking.php? Thanks a lot INTELGOD!

Buy the Intel Tuning plan and RMA 😉

Going from 1600 to 2133 might happen but 1600 to 1866 is more likely doable. On windows 8 core parking is disabled anyway so no worries

Well, I mean I could still return it no problem.
I currently have running @ 4.2GHz pretty stable (but have to do some more stress testing) and was pretty ok with it.
But now you got me thinking....

At 4.2Ghz you're equal to a 4.6Ghz Ivy and a 5Ghz Sandy. Its up to you ofcourse 😀

Mine is only stable at 4.1Ghz. Before I can run 4.2 but then, when I play hours of BF3 multiplayer it bsod's.

 

[Intel God]

John that's really weird. I look at your settings and everything looks good.

 

[Intel God]

I cant edit my posts thanks to 404 errors. have you tried the Asus OC tuner john. What presets does it have?

Last time i did the ASUS Auto OC, AI Suite III overclock, It did a per core overclock (43,42,41,41).

I'm able to get a 4.4 at 1.246w maxing out at about 59-60C with prime after about 3 hours. However, when I have CPU Volt set to Auto and try for 4.5Ghz it bumps the voltage up to ~1.35v and the temp maxes out about 68-69C. Should I just keep the CPU at 4.4 or is my voltage safe above 1.35 at those temps? I'm new to this OC'ing thing. Thanks for the help

68-69 is not bad at all. I wouldn't use auto though, it uses more voltage than what's needed, and things seem to get dicey after 1.35ish I would try 4.5 at like 1.3 or possibly a little lower voltage and see what it does

I can step it up in incriments from where 4.4 is stable at, however, is the difference really noticeable? I feel my temps for 4.4ghz is pretty solid or atleast is better than what I've been finding on this thread. Also, if you could explain to me the dangers of running voltages over 1.3 if the temps remain "safe"? Like I said earlier, I'm new to this OCing thing. Thanks in advance

 

[Christian Angelo]

That's the big thing for me as well I'm at 4.2 because my jump to 4.4 was far to great in the voltage and heat department. I'm sure there's tweaking I could do but I've been too busy to deal with my oc. But I'm rambling, 100Mhz isn't going to be very noticeable, so if you're comfortable with where you're at with 4.4 I'd stick with that.

The dangers are mainly heat related, but if you're only getting 70 degrees, then you're okay. For haswell it seems like the place to get worried is high 80s.

Safe voltage on haswell on air is 1.45v but you'll never even get close to that on the stock TIM

Sounds good man, thanks for the help. I'm not trying to sell anything to you but I first bought a Zaleman or whatever copper CPU cooler from Newegg and was sitting in the low 70s at 4.1-4.2 and got fed up and bought a Corsair H55 from Best Buy for the hell of it as I was getting fed up and man idling at 4.4 is around 25-26C and under load is 54-57C with a max spike aroud 60C. I was extremely impressed.

 

[Christian Angelo]

Thanks for that clarification Intel God

svtkid97, yeah I'm on air right now, I don't think they sell it anymore more but it was a corsair A70. It's not the nicest but it fairs well, I think it's more of my chip than my heatsink. I've been considering a closed loop but I'm broke after buying this 4670k upgrade 😛 and I'm not sure if it'll benefit me much.

Im not sure what you mean by stock TIM. If you could give me a brief couple of steps to see if I can achieve a higher clock that would be great. For reference I'm running Asus Z87 Pro MOBO, 4670k, 8GB 1866Mhz G-skill. Thanks for the help

Wow you got a pretty good chip buddy!

 

[ACX770]

Thanks, running 4.4GHz Stable after ten runs!

 

[airplanegeek]

WTF...I'm on an i5-4670K at 4.4 and im getting 60ish GFLOPS in IBT. This is my first time overclocking but without the overclock i get 48 GFLOPS. Anyone know why?




Nvm, it somehow fixed itself, im now getting around 110 GFLOPS

 

[johnvonmacz]

Just got my 4770K replaced and now I can hit 4.5Ghz no problem! So happy! 😀

 

[Som3one]

I might be getting even more jelous but at what voltages and temps?

 

[johnvonmacz]

I might be getting even more jelous but at what voltages and temps?

I settled @ 4.4Ghz
- 4.4Ghz @ 1.14v
- Cache: 4.4Ghz @ 1.14v too
Temps
Highest 75C
Lowest 30C

I think it has something to do with the batch number. My first one is a L311XXXX chip and totally bad chip, bad overclocker. My Second (current) one is a L310XXXX chip and so good in overclocking. I can hit 4.6Ghz @ 1.18v but my Kraken X60 is not enough to handle it as my temps go as high as 88C.

 

[Som3one]

Yeah, I was right.
I got more jelous. 😉

Do you use the stock fans on your Kraken?

Also, have you thought about delidding your CPU? (Not suggesting, just asking.)
