Yes, it should be fine.
 
I think I have an average chip My 4670k stable @

4.4 with 1.2v+0.020 offset
Cache 3.8 with 1.2v

Pass IB/prime/Aida
Extreme IB
Done all 3 test in prime


TEMPS underload
Max @ 78-80C
Average @ 68-72 C
Min @ 54-56 C

Idle @ 31-37 C

H80i x2 fans fix RPM 1700
AR z87 extreme6
Kingston 4gbx2 800mhz XMP profiled 1600 9-9-9-24

Now here's the problem I can't set cache ratio higher than 4.0. @4.0 It will pass all test yes. But reponsiveness seems slower including boot time. I want the cache ratio to Atleast go as close to CPU core which is 4.4 but even how much voltage I add the primetest freezes from 4.1-4.4 cache ratio. I tried slowly volting up to 1.3v to both core and cache voltage to no avail. so am I stack to this setting? I think volts above 1.3ish is bit too much. is it best to keep 4.4core and 3.8 cache? Or can someone help me push it further. Anyway I'm positive I can still push CPU core up to 4.5 with the expense of low cache like around 35.

anyway I didn't touch any orther voltages yet except core and cache voltage

Any advice?
Thanks!
 


Try a benchmark, like Si Soft Sandra with different settings. I have found that higher CPU ratio+ lower Cache Ratio works better than the opposite.

Hi Yogi thanks for helping me the second time. am not sure but i think it was when im choosing Motherboard and GPU :)

back to topic. ok ill try your suggestion bout si soft sandra but before that I tried benching using 3Dmark 11 performance. Scores @5880 and i think is kinda low. Dont you think?

im already stable @x44 + x38 on cache so if i make any adjustment like increasing or increasing cache. aside from cache voltage is it necessary to adjust System Agent voltage offset? coz i leave mine @ default +0.00

and please dont mind for further response, i made my own thread bout this topic for a clean start,

Ok tried different settings.
1st attemp succesful 4.5ghz
x44 vcore @1.250 overide
x38 vcache@1.280 adaptive.
system responsiveness little slow. And i dont know why but while starting from cold boot Radiator fans go wild for about 4 seconds before it settles down. Also a 3 beep sound as it boots.

2nd attemp (UNSUCCESSFUL)
x44 core, vcore @1.265v Adaptive
and x42 cache, vcache @1.260 Adaptive
Adaptive voltages for both core/cache. while testing with intel burn i checked HW for Vcore and its spiking for about 2-4 seconds @ 1.34ishV then go down again to 1.29ish.
vcache is steady @ 1.290v temps are bit too high real temp shows 89 C max same in HWmonitor. I Stop the test!

3rd attemp. Most successful i think?
x45 core, vcore @ 1.265v overide
x42 cache, vcache @1.260v adaptive it max @1.290.
as you can see here from intelburn result compared to 1st attemp i have lower Gflops but take note that in the 3rd attemp i have faster Time(s) which means a faster proccessing. 3rd test finished almost half the total time of 1st attemp. PC responsiveness, boot time is also noticeable on this 3rd settings.

I need help myself, but hopefuly my post can also give some tips for those who needs it.
I didnt touch anything else in BIOS except disable power saving and enable buttons for better overclocking.
Voltages - i didnt change anything except vcore and cahe core.
Multipliers - only change Multicore and Cache core.
Everything elese @ default

add info:
-Asrock Z87 Extreme 6
-RAM 2x4gb hyper kingston XMP'D 9-9-9-24 800Mhz @1.650v
-Cpu cooler Corsair H80i


well guys i think this is a decent chip? am i wrong?

If theres still something to fix with my settings ill really appreciate your help or advice.

Thanks!


 


Does Haswell have such a setting? I've never seen it in my MSI mobo.

Hi guys, i was curious to see how temperature will go high with my i5 4670k on stock settings 3.4(3.8 turbo). I run IBT on high 10x times on high and i opened task manger. What bugging me is, all the time during test CPU usage was 100% but CPU speed was at 3.3GHz also all the time. Shouldn't it go all the way up to 3.8GHz? Also when overclocked CPU temp on each core during benchmark shouldn't go over 80 C right?
 
Wow. I just had to make an account to thank you! I was trying all speeds and voltages etc and this one with the exact settings is the most stable I've gotten at 4.4ghz (756 in XTU) I couldn't figure out what step 2 is in Intels over clocking software or in the MSI BIOS. Can anyone who has one of those tell me what it's called there? Thank ya :)
 
Right now I'm looking into OCing my 4670, but I'm a little worried about my stock temperatures. I'm running the i5 4670k on an Asus Hero VI, with a Corsair H100i cooler, with new Arctic MX4 TIM. Running Prime95 FFT i'm maxing at 89C, full load averages 75-85C, and no load in the 25-30's. In LinX max I saw 79C max. At stock are these temperatures worth keeping and trying to OC, or do I have other issues?
 
Guys I'm running a 4770K on a H100. I applied the max recommended voltages in the OP but I get strange problems.

In aida64 stress test it says the cpu is overheating and has throttled even though the temps looks ok (around 80ish). If I use IBT standard or high the temps immediately shoot to 100 degrees. OCCT stops saying there was a problem (but won't tell me what the problem was, and I stopped it from stopping when the temps get to a certain point, so it's not stopping because of temps, and the temps average around 80). If I keep trying OCCT it will eventually blue screen.

I don't know what to do.

Update: Even rnning IBT at stop my temps go over 80... strange, I don't hear my H100 fans spinning up (SP120's).
 
With my ring bus on 34 and my cpu ratio on 43, I got stability at vcore=1.23.

Here are my next steps (tell me if this is ok). I will slowly reduce my ring voltage, when I found the lowest and am stable I will begin reducing my input voltage to the lowest. Is that right?
 
I just left my cache on auto at x39 f it. I did manage to stabilize at 4.4 with 1.280v. I think my input volt is 1.9 or something. I'll have time to play around with it after I do my hitch in the oil patch.
 
I'm using an i5 4690k with a kraken x61 280mm rad aio cooler. I got plenty of air flow too and good temps.

I've been searching the Web for an answer to my question but everybody seems to have very diverse opinion on the matter.

What is the max safe voltage for an i5 4690k with my current cooler?

At the moment of writing this I am stable with 4.6hhz at 65c under full load prime 95 2 hours +... My VID is 1.295v at the moment and vring is 1.235... I haven't yet started thing to lower these voltages to see if I lose the stability.

My ambition is to reach 4.8hhz with a 1.3v-1.345 VID

Just want to ask at which voltage does the haswell chip degrade or damage itself..

Now don't give me your personal opinion but the hard facts. I need to know what "is safe" not what you "think" maybe might be safe.

I intend to run this as a daily oc. When I'm done finding my stable oc I will lower some voltages and kick in c-state and other power saving features that help the CPU to "unwin" every now and then
 
 


I personally wouldn't go much higher than 1.3ish vcore and 2.2ish vrin
 
I'm stable with my 4670k at 4.4, but after messing with voltage my idle temps and gaming temps are mid30s to mid40s with a kraken x61. On IBT it peaks at 81-82. Not sure how comfortable I should be with that.
 
My Vcore is at 1.220. I didn't think too much of it, but the fact that the temps are extremely close between doing something vs idle doesn't make sense to me.
 
I have my OC at 4.6ghz, my OC method is
OC tuner= XMP
Core ratio 46
Max CPU catch 42 Min at 38
Core voltage @ Adaptive
Additional turbo mode CPU core voltage 1.35
Core catch voltage= Adaptive
Additional turbo mode CPU core voltage= auto
Eventual CPU input voltage=1.90
DRAM Voltage=Auto
My CPU runs idle at 0.8mhz at high 20s to low 30s and under ROG Realbench stress test mid to high 70s. You also got to make sure you change your settings in Windows power saving options also, control panel/ system and security/ power options/ then select balanced
 
Can't wait to get my i5 4690k and hopefully I get a good overclocking chip! The chips are usually binned so I should get 4.4/4.2 on a lowish voltage fine. Will update when I get it.
