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

[Y0GI]

Oh. My chip isn't that good. I was only running 1 core and didn't know it.

Run "Core Temp" during testing and it will show individual core temps and % Loads.

Any tips for 4670k + ASRock Extreme 4 ?

So far I tested 4.0, 4.1, 4.2 and 4.3 all stable with prime 95 for 2hours each. But when I tried that 4.4 it just BSOD for the first 30 seconds.... currently using a 212 evo

I have the same board so far i got it to 4.3 try so many setting to get it to 4.4 n nothing either i pass IBT n get a blue screen on prime95 or i will get a blue screen on IBT

I'm back to my overclock of 4.2 ghz at 1.210 vcore with adaptive on.

 

[airplanegeek]

idk why but my chip runs at 70 C on a thermaltake water 2.0 water delidded at stock speeds.

 

[DeltaRecon2552]

I'm now up to 4.3 ghz at 1.230 v. Nothing at 4.4 ghz is stable with safe temps.

I am at 4.3Ghz at 1.28v nothing at 4.4Ghz either i pass IBT n when i test on prime i get a blue screen so when i try to change the setting i get a blue screen on IBT so i left at 4.3Ghz

 

[DeltaRecon2552]

Crashed in Planetside 2 at 1.235 vcore... Trying 1.237 now on Prime95.

Crashed. Back to 4.2 ghz....................

I dropped back to 4.2 because I wasn't stable at 4.3...bsod after an hour n a half stress test using intel performance tuning utility...when i went back to 4.2 it also crashed so i upped the voltage to 1.3 and ran stress test for 5 hours at 4.2 with no problems and temps stayed in the 70's or lower...so i dont know why i cant get it stable at 4.3 or higher

I am trying to get to 4.4 i am at 4.3 past IBT on hight n ran prime95 for 5 hours n no errors or blue screens temps where lower to mid 70s on prime95

I'm staying at 4.2 ghz. No point in up-ing the vcore from 1.220 to 1.250 for an extra 200 mhz.

 

[Joniostis]

i need to follow this

 

[DeltaRecon2552]

Just put my overclock into BIOS...
4.2 ghz on all cores
1.220 adaptive vcore
Vcore Offset 0.002

I have to up my voltage from 1.25 to 1.31 for an extra 100MHz to 4.7GHz. Worth it? Yes! for the lolz!

 

[DeltaRecon2552]

Okay... I maxed out at 4.2 ghz at 1.222 adaptive vcore. I just read this thread (http://www.overclockers.com/3step-guide-to-overclock-intel-haswell) and these guys are getting 4.7 and 4.8 at 1.2-1.25 vcore. I'm really starting to question my overclock....
Will adjusting my CPU Cache Ratio to be closer to my CPU frequency help stability?
Will OCing in BIOS grant me better clocks than AI Suite III?
What do I need to do to get these awesome overclocks at low vcore?
When I get home to my PC I will take screenshots of AI Suite III for you guys to see my settings.

I thinks it depends on the chip mines needs 1.28v to get to 4.3Ghz if the chip is good then u could reach 4.5Ghz on about 1.25v to 1.30 maybe less which i seen on here n on other sites i am trying to reach 4.4Ghz n nothing yet

So I ended up replacing a faulty 4670k thru newegg at no cost so I have 2 now and I tried overclocking the new one and I can boot and run stable in Aida64 for 2+ hours at 4.4 with vcore at 1.23 and input voltage at 1.85 but my temps get kinda hot for some reason. 2 cores peaked at 88 but they all average in the 70's. I'm thinking this is because I never dropped my cache voltage back down from 1.25? I will mess with it later and report my results, but this new chip was able to boot into windows at 4.6 I just didn't test it for stability at that speed because my temps were way to high, which isn't making sense since my voltages are relatively low and im using corsair h100i water cooling.

my cpu was an oven. my cpu reached 90 C at 1.26 V

Thank you very much for this thread.
I've managed to get 4.4Ghz, but safest for me now is @4.3GHz 1.18V (i5-4670k, asrock z87 extreme 4).
In Prime, temps reach 90 degrees.
Problem is when I went to buy my PC at that time I didn't look at the CPU coolers so the guy there suggested me Intel XTS100H.
He told me it has 2 modes "Quiet and Performance" (now its in Quiet mode) and "really keeps everything cool and quiet".
Truth is - even in quiet mode I can hear it from the other state, so until I buy a new cooler I'll keep it at this.
Edit: Hyper EVO 212 still a good cooler for that price or ?

By most accounts, it is a good value priced cooler. It you would like something better and quieter, Have a look at the Noctua NH D14.

I guess i do have a bad chip meaning not a good overclocker one mines needs 1.28v n 2.1v input to run prime for 5 hours temps hit middle 70s n on IBT on high for 10 runs middle 80s using a noctua NH-D14 with 3 fans try so many setting to get it to 4.4Ghz but nothing either i pass IBT then get a blue screen on prime or i get a blue screen on IBT

 

[DeltaRecon2552]

Hyper 212 is a good cooler for the money.

Havn´t visited this topic for quite some time but now I have gone full custom loop which can deal with my temps much better than my previous Kraken x60. So, I thought I´d give it another try.
Before the custom loop I was running at 4.2GHz @ 1.2 Vcore, everything else to Auto since my motherboard seems to be pretty good at setting the other voltages up correctly.

Anyway, at 45GHz with 1.3V VCore, Cache Voltage at 1.2V and Input Voltage at 1.9V I got the following results:
x264 HD Benchmark: 12 runs and stable.
IBT: 15 runs and stable with temperatures at around 85°C with a few peaks to 89°C.
Prime: Not stable.


I tried to get it Prime stable and am currently at 1.36V Vcore, 1.94 Input Voltage, 1.22 Cache Voltage, Ring Bus at 35 and RAM to 1333MHz but it doesn´t look good.
And I won´t go higher on the voltages since those are my BIOS settings not the stress test readouts with the offset.


Do you think it´s worth to try the IBT-stable but Prime-unstable setting for general usage (meaning game stability testing)?

I would give it a try. You've got nothing to lose.

mines takes to get 4.3Ghz 1.285v n input 1.9v n cache at 1.20 pass IBT 10 runs on high pass n ran prime95 small FTT for 8:10 hours n no errors but try to to set 4.4Ghz n nothing
