Hi guys, ok i thought i was stable at 5ghz but i started getting BSOD . so ive started overclocking again with this cpu. System specs are in sig.
Ok so im looking for 4.8ghz stable, i think i have it now but the settings i have and the volts i think are too high. can you guys tell me what you think.

Bclk 100
Turbo 48
Epu Off
Pll overclocking internal Auto
LLC Ultra high
VRM FRQ man - 350
Phase Extreme
Duty T Probe
Cpu Current cap 100
Cpu voltage 1.44 ( i know this is high im just testing ) bsod on 1.41

Ok so even 1.44 just BSOD on me so somethings wrong. Ive just gone down to 4.5 for now. Any help at where to start would be great guys. on 4.5 ive set the cpu voltage on 1.33 and pll voltage on 1.85. seems fine on that. But that too low an overclock for me

Going to work so ill check this later. thanks guys

Not all cpu's clock with the same voltages, my 2600K needs about the same as yours for stable folding 24/7 so providing temps are ok its within the Intel specs

Change to C probe

CPU Pll to 1.90

and then on boot lower the vots a tad so that cpuZ read cpu volts at about 1.432 or there about

and then try again
 
stick with your set voltage say 1.415 and then set it to 4.8 load up windows if it boots thats the first step.

next load up prime 95 and realtemp and keep an eye on the temp,

put intel burn test on max setting and click start if it bsod or freezes then youll have to lower the multi down again till you find a stable spot. if it passes stick the multi up again by 1 and repeat

mine manages 4.9 but im putting a lot of vvolts 1.415 into it, i might lower the clock down to 4.8 as that was wirking with 1.35 but i just wanted a bit more out of it.

not all i7's can do near 5ghz without silly temps/voltage ive got 7 i7 2600k rigs so far tested 4 and they have been 4.6, 4.6, 4.5 and 4.9 so you may or may not have a golden chip but the 4.6/4.5 setups have been put to 1.38v max and then worked from there tofind it stable.
 
leave pll on auto it doesnt really affect the sandy very much, i use settings of

disbale PLL overvoltage if you want to use the sleep function

Bclk 100
Turbo 48
Epu Off
Pll overclocking internal Auto
LLC Ultra high
VRM FRQ man - 350
Phase Extreme
Extreme
Cpu Current cap 100
Cpu voltage 1.38 safe max voltage
 
Ok ive tried these settings with no luck.

BCLK - 100
TURBO - 48
EPU - OFF
LLC - U HIGH
VRM - 350
PHASE/DUTY - EXTREME
CPU VOL - 1.43
PLL - 1.90

Booted into windows fine. But running prime i got a BSOD and on windows load again the BCCODE was 124, which if im right is vcore? how much more vcore do i need for this guys cos 1.43 is high

ive read the highest safe volts for the 2600k is 1.52?

anyway just to test i upped the vcore to 1.45 and its now stable. well cpuz reads 1.45 but bios said 1.47. to keep 4.8 with a lower vcore may not be possible for me with this chip.im sure i can go a bit lower though. By the way temps are still under 75 on prime
 
well its been running prime 30 minutes now, yes i know thats not long but i couldnt do that before. Temps are under 75 and im on 4.8. but the vcore is 1.47 in bios as i say. but cpuz reads 1.45. I might try lowering this a little and try running prime again. What temps should i try and stay below? would something like 85 be the max guys? because if i kept this voltage i could prob get 4.9 or maybe try for 5 again.

what do u guys think? and yeah ive read no one actually knows what these chips are capable of yet. scary

Keeping the same volts im gonna try priming 5ghz now. :)....... That failed, so 5ghz for my chip must need even more.

Ok so ive gone back to 4.8 and lowered the vcore i touch to 1.45. ill try priming this and see how it goes.

Update... ok well i tested the 4.8 on 1.45 and it BSOD , so even for 4.8 it seems i need as much as 1.47. gonna try 1.465 now.
Why am i needing such high volts?? is there a setting or something i should be changing

Running above about 1.4V constantly isn't recommended by the community. Intel don't recommend it either. Hit whoever told you 1.52 was the limit round the head with a (metaphorical) shovel. And geeman it's true nobody knows. And in such situations it's better to be cautious rather than running blindly into the dark and smacking your head against a wall. ;)

there no proof either way mate that its not enough or its too little. If i changed some other settings maybe i could lower the volts. As i say all ive changed are the a few settings. wouldnt keeping EPU enabled mean the high voltage wouldnt have to be used all the time?

Your choice, if you want to risk it I'm not going to tell you otherwise. But it isn't advisable. Download CPU-Z and you can monitor in real time what voltage is being fed to the CPU.
 
yeah ive got cpuz running, but in bios i know EPU is disabled as people have said to do. but if i keep that on wont that be better?
What about changing other settings like VCCIO, PCH ,QPI. etc i havent touched any of them

sounds to me your chip isnt capable of 4.8 or so, try 4.7 or 4.6 maybee even 4.5

there are few chips ive found that go over 4.6 i have 7 of the 2600k and only one so far (still got 3 to test) has made it to 4.9 others have been 4.6 and 4.5

You're unlucky.

I have two 2600K's and I overclocked both to 4.8GHz in a few minutes with little effort.

I'm sure they'd go higher but I've not tried as 4.8GHz is plenty.
 
the ones i have yet to try are the ones made in costa rica and a lot of people reporting them to be the good clockers but cant do them till ive sold the other 3 setups ive done
 
Well its stable on 4.8, but using the voltage im on now is high. But im still going to leave it , 12 hours stable with prime. 1.46 / 1.47 cpuz reads!

You just got unlucky chip mate just like mine. I know the feeling but ocuk always do 4.6GHz no more than that with a reasonable 1.35-1.38v. You will kill the chip if you going to get vcore around 1.465V is totally madness just for 4.8GHz.
