I have just got a 2500k and would like to find the max OC,
What is the max SAFE V-Core Voltage
What would be a recommended ever day V-Core voltage

It's under custom water so cooling is no problem, i just want to find the max OC then i will wind the voltage in to a safe ever day voltage

Best i have seen with a 2min play was 4.4 @ 1.25V all other setting at stock

Wouldnt go higher than 1.45v. 1.45v should be ok if you can keep it cool.
 
i really dont recommend going that high, yes seriously, im running a 2500K myself, 5GHZ at 1.42 volts stable, under water so its cool.

i would creep up to a clock speed that you are happy with and then slowly go down on the volts.

I have always just run systems at stock but after having problems with my last CPU and it been very near crimbo i have to buy a used 2500k and there supposed to be good clocker s so i thought it was time i start to lean the air of Oc'ing.

I am going to start at 1.45 to find max clock, then i will drop the a stable clock around 4-4.2 and just work out V-core from there.
Any tips on clicking would be nice

what are the load temps like on your 5ghz?
 
That seems ok i guess, but 1.45 is still bloomin high, as for me, at 5ghz, i did get 35 - 40.c idle, but now i have to R9 290X cards in the same loop, so idle temps of around 38 - 45 so still not to bad.

Keep us up to date on how it goes :D
 
1.435V @ 4.7GHZ doesn't go over 65C in games, had it for nearly two years if not more :)

Would be able to hit 4.7GHZ but heat in testing becomes an issue.

4.6GHZ/4.7GHZ is the sweet spot for most i5 2500k's

- There is nothing wrong with volts up to 1.45 as long as temps are kept in check

Its been proven that the level of degradation for high voltage overclocks is something to look out for with these chips.

What level of degradation? As I said nearly two years here and each chip is different, I know for a fact of some people running at 1.5V for just as long if not longer with water cooling.

Just keep it cool and make 1.45V your very max, don't go over that, lower the better
 
Wind it up :D

5.5GHz @ 1.67v

With caution!!!
Keep it cool and deg isn't (or wasn't for me) an issue :)
 
i got:
5.0Ghz @ 1.45V, crached at windows load screen
4.9Ghz @ 1.45V, crashed in windows
4.8Ghz @ 1.45V crashed in second run on LinX
4.7Ghz @ 1.45V, idle 34, load 70 - 3 runs of LinX

I am running 4 sticks of ram so not wanting to go mad with the clock as i know that can hold it back. What would the Stock PLL voltage be? i would like to give it a little bump
 
A lot of i5 2500k's don't like going over 4.7GHZ like mine maybe related to heat, but voltages would have to be at the high end of 1.47v, not worth it :(

I run 1.65 for PLL but thats on a 3930k.

Bio set to 1.45, CPUz reported 1.432

Now running
4.5Ghz @ 1.4V(dropping with each test), Idle 34c, Load 63c, Skydiver run 53c
 
4.5Ghz @ 1.375V, Idle 32c, Load 60c, Skydiver run 52c,
All settings at auto apart from V-Core, its runs linx and 3d mark that the same time.
Is there any settings i need to be looking at changing or am i ok to keep them at stock
