to get 5GHz stable will take a lot more volts than your 4.5 oc try upping it to 1.45v but make sure your llc is not on max! back you llc down one notch, you will boot in to windows then, once in windows start cpu-z and a HWMonitor and keep an eye on your temps and volts then run a prime blend test.

WHAT COOLER DO YOU HAVE?

Running water, shouldn't be an issue as far as temps. I'm running 4.9 right now and ~1.45v and she'll hang there throughout the benchmarks (mainly gpu benchies). I'll give that a try, +1 & thanks

Yes. I think I know what might be going on (same thing happened with my old 1366 i7 950 when I pushed it to 4.4), the os is lagging. For some strange reason its does this when I'm running high clocks. I'll go 5.0 this weekend.

Do all the thermal features increase the life of a OCed CPU?
I mean i have 4.5 ghz 2600k and stopped at that because i had to set 1.35vcore, and to be honest 200 mhz are not worth more vcore the difference is minimal, i dont know much and i thought that lowering clocks and speed when processor is idle would increase its life, isnt that the real matter? or you recommend turning all off and stay overclocked all the time?

thanks

For every day use and most gaming it really doesn't make much difference. For benchmarking, every little bit counts.

I run 4.5 (@1.305v) 24/7 and its perfectly fine for my gaming needs. For benchmarks, I can achieve a high 4.9 (still looking to crack 5.0 ).

hi there , i have a core i7 2600k and a gigabyte z68ud7 main board....

ive tried to follow this guide.......so far all i can get to is 4.0ghz by adjusting the multiplier.....ive tried 42 = 4.2ghz this is hit and miss......

my aim is to get 4.6ghz if its possible......i set the multi to 46 and left the voltage on auto......i get to where the windows logo starts and it freezes...bsod.

now ive tried to adjust voltage and dont seem to get any where, possibly cause im not sure im doing this correctly......

i go into bios and advanced voltage.

and where it says:

cpu vcore 1.365 [auto]

am i supposed to adjust the voltage next to where it says [auto]
from the drop down menu?

the reason i ask is the cpu vcore values never change to what i have set....

and also the vcore on the pc health never matches any of these numbers......just a bit confused........

The 1.365 that the BIOS shows is the amount the board would provide on auto setting. You just set it to what you want from dropdown menu (or type it yourself) and that's it.

hey sin thanks for the OC GUIDE.
i did what was in this guide and i was relatively stable at
45x@1.315Vcore & LLC = level 6
im on a gigabyte z68xp-ud4, kingston hyper x (2x4gb), i5 2500k.

i tried changing the qpi/vtt voltage from 1.05 to 1.10 and my computer would not boot.
it would power up and then power off before even making it to the beep.

i cleared the cmos and was able to boot with stock settings.

now if i make any changes in the bios to the multiplier or vcore voltage or anything like that it will just power on/off continuously until i turn off the psu and clear the cmos again for default settings.

thanks in advance

Have you tried updating the BIOS? I believe that there was a recent fix for boot loop issues. Take a look at this thread on the Tweaktown forum. Note that these are beta versions, so flash at your own risk.
