hello, as title show i'm searching the tue method to overclock my cpu i5 4690k on gigabyte z97 gaming 5
so, excuse me first for bad english
and this is my config:
- case: cm storm trooper
_Os : windows 8.1 pro 64 bit updated
_mobo: gigabyte z97x gaming rev 1.0 with f5 bios
_cpu: i5 4690k
_cpu cooler: cm nepton 280l wiyh two 140 cm fans (stock)
_ram: kingston hyperx 8go (2x4) 1866 mhz xmp 1.65 volt default
_gc:sapphire r9 290 tri x
_ssd: samsung 840 pro 128 go + hdd samsung 1 to 5400 rpm
_psu: cm silent pro m2 1000 watt
my problem is when i tryed to overclock my cpu to 4.4 ghz with 1.21 vcor valu it's done with 65° max on stress test with aida64 test utility, but when i try to turn on eco solutions as : CE1, C3 state, C6/C7...... ext to reduse frequency when it's in idle it dont downgrade the multiplier & frequency it syuck on 4.4 ghz all the time and crash after a few minutes without stress test example when i open an application or when i'm on desktop
pleas help me i'm new user with intel hardware i was with amd 990 fx platform with fx 8320
thanx to all

It is recommended to leave all c states off if overclocking. It can make things unstable and its just a big headache. The majority of the overclocking guides on here all say to turn off c states. EX: http://www.overclock.net/t/1490835/the-gigabyte-z97x-overclocking-guide/ . Hope this was helpful, I have a 4770k @ 4.7ghz with all c states turned off.

If you want the CPU to save power at idle, you should enable the C3 state alone, according to the guide in the previous post. The other C states offer relatively minimal power savings so they aren't really worth the trouble anyway.

Most likely, your CPU is not getting enough voltage when it enters a power saving state. This may be fixed by increasing the voltage by a small increment, If you're lucky. Another possibility would be to experiment with different levels of CPU VRIN Loadline Calibration. Unfortunately, that would force you to also experiment with completely different VCore values.

For example, on my Ivy Bridge motherboard, I reduced my LLC by a level or two and then adjusted VCore so that the peak voltage was the same as with previous stable settings. Consequently, the minimum voltage increased which helped improve stability under power saving conditions, from my perspective.

so i understand that i should activate only C3 and increas vcore value from 1.21 to 1.22 for example ?

Yes go ahead and try that. If it doesnt work you can try bumping it a little more. If it just isnt working after you try it a couplw times then you might have to leave it off if you want to maintain that clock speed.

hello, i'm stuck on 4.2 ghz with 1.24 vcore and could not have more than 4.2 even if i set the vcore to 1.30 the system can't boot on 4.4 ,for information i'v just modify vcore value and my memory profile is set by defailt to xmp profile 1 wich is 2400 mhz.

I am in the same boat, did you get any higher OC? Please share your experience.

In my case, I am stable 4.2ghz @1.2vcore, but nothing after that, I am able to get into windows...

I have even tried 4.3 @1.285 vcore but just before 10 mins stress testing in ETU computer just freezes.

4.3 @1.225 - ETU stress test - PC Freeze within 10 mins
4.4 @1.285 - ETU stress test - PC freeze within 10 mins
4.5 @ 1.30 - ETU stress test - PC freeze within 10 mins
