Ok i just recently upgraded to a i5 4690k and have been reading and trying every guide i can find on overclocking and have had no real luck at getting a stable over clock except when i tried easy tune and hit autotune. i have had a couple of decently stable oc at 4.5ghz with temps at 61c with my cooler set to quiet mode. I have corsair 110i gtx cooler. Mostly my problem is the bios menu has so damn many options under the voltage menu that i get lost quickly. i have had most luck at 4.5 core 4.0 uncore and 1.275 vcore. Any advice would be greatly appreciated.
First of all, nice choice of components.
Secondly, download the following free and safe programs:
- HWmonitor
- CPUZ
- Aida64
- Intel Burn Test
- IOBit Uninstaller
1st rule of overclocking...never, never, EVER use an auto-overclocking program. Ever.
Using IOBit Uninstaller, uninstall any programs you have used to OC your CPU. Dont, just uninstall it through windows...use this program, it is far, far more thorough.
Your biggest problem is your Vcore is likely far too low. A "stable" OC of 4.5 ghz w/ a Vcore of 1.275 Vcore just doesnt sound right.
Go into BIOS, do it the right way, the manual way. It's very easy. Set your Vcore voltage to something like 1.3025 and your CPU multiplier to 4500 ghz.
Run HWmonitor, CPU-Z and then do a quick 10 runs of Intel Burn Test on Very High. This should quickly tell you if its stable or not. If it's not, and you still have some room to safely increase temperature, bump up your Vcore another 0.050V and try again. Keep trying until you either reach and unsafe temp or you pass Intel Burn Test on Very High.
Now comes fine tuning. This is the laborious process where you need to find the perfect balance between your clock and your Vcore in the long term, hence using Aida64's stress testing feature.
I'd also try to bump your uncore to 4.2 or 4.3 if possible.
Let me know if you have questions.
