Haswell Overclocking Guide [With Statistics] - Page 276

post #2751 of 19539
Ok I think I finally got it down. Reseated IHS and H100i.

Prime95 28.1 Avx2 doesn't go over 74*C on hottest core with 1.260v @ 4.4ghz

LinX AVX 2 @ 2GB hits 79*C over 10 runs.

All this using HWInfo64. I found that HWMonitor has temp differences? Weird. Usually 10*C hotter. Anyone else with that problem?

Also had a mad discrepancy before between cores, but now all are within 6*C when at full. Was like 10-12*C sometimes before.

I'm currently at 4.4ghz@ 1,200V with my 4770K rock solid...but....no matter how high is the Vcore it freezes on 4,5ghz. Is it possible, that it runs stable at 4,4 on good voltage, and dies at 4,5?



Settings:
multiplier 44x
turbo off
vcore 1.200
Vrin LLC extreme
Vrin 1.9V

Any thoughts to stabilize it higher? Its not life and death, just wanted to try how high it can go.

You might have hit your voltage wall. I.E. It takes waay too much to push 100Mhz faster. 4.2 takes 1.2 but 4.3 takes 1.35 for example.

I'd slowly work your voltage up just to see what it take to get it running. If you can find something that it stable enough to boot, you are close.

Also should i try something other than prime 95? Reading back i found some ppl had their system perfectly stable, only prime killed it...and thats the one im testing the settings first...

LinX with AVX2 is more difficult. And I can also see you are running AVX prime95, not FMA3 which is the latest for Haswell processors. Essentially,y ou are running a MUCH easier version of prime95. Guaranteed you will fail within a few minutes using the new prime95.

You can find prime 28.1 and LinX 11.1.0 there.

Ahhhhhhh, now i understand coil whine...
Its just an frequence which is in the resonance area of the coils and brings them to swing....no damage at all for the components....am i right?! :8


(Only coil whine with p95 12k,18k not with lynx,Aida, occt,ibt,gaming,rendering....so f*** prime xD )

I have the very same issue, 4.4 no prob, 4.5 no way

I've had 2 video cards over the years w coil whine, both of them died within a week of the coil whine appearing and both where RMA'ed.

I'm having problems with CPU VID jumping past the adaptive voltage that I have set in the bios. It jumps from 1.293v to 1.351v in HWMonitor (set to 1.291 in BIOS) while only playing games but the vcore stays at either 1.296v or 1.312v. Is this something I should be concerned about? Or not, since the vcore stays close to what I set it to? So far this happens while playing World of Warcraft, Borderlands 2 and League of Legends. I have tried running Cinebench and the VID stayed at 1.293v with vcore at 1.312v.

Here are my settings in the bios:

cpu: x46
cache: x44
ram: 1866mhz xmp
vcore: 1.291 adaptive
cache voltage: 1.255 manual (I've also tried adaptive and it does the same)
ram voltage: 1.5v xmp


Besides these I've changed nothing else in the bios.


Here's a screenshot of my HWMonitor after gaming




Here's my specs

i7 4770k
Maximus VI Hero
Corsair Vengeance Pro 1866 8gb
Corsair AX760
Windows 8 Pro x64

But i read now 4 threads and they all say its not dangerous at all and i only have coil whines with p95 12k and 18k not in daily use...
