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

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?
 
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 :(

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
 
TBF that sounds like very bad luck, my 770's are both +110Mhz on core with no voltage bump.
now running 4.6Ghz @ 1.375 Vcore.
so today i will do 4.7Ghz and game all day, i dont just want a moosive clock it as to be usable too.

temps i get now are GPU a massive 37c(Load).... and CPU 51c (Load)
Load is gaming not stress testing

the boy on dirt showdown free running for 2hr's(this when max temp was hit)
Me titan fall, Cod, Sniper elite 3.

I too get over 110Mhz overclock on both of my R9 290Xs, but as the cards are new (water cooled however ;) ) the coil whine does my head it!!!

As for temps, i get 26.c idle for the cpu and a similar result for the graphics cards, but under load, im hitting 45 - 50 on the cpu and around 55.c on the cards.

To be fair, i need to upgrade my water cooling asap as its not up to the job of a 5.00Ghz processor and two 290X's that are running a high overclock.

I am also running water cooling. 3 blocks with a 360 rad in case and an 540 rad outside the case. the rad outside the case made a massive difference as its not pulling hot system air in to it.

My idle temps on the CPU are 31c but i dont have the best block

@ Disco_P, my rule with GPU's is always buy reference i find i always have very good luck clocking ref cards, but my 7970 windforce was horrible
 
ok so i found 2 clocks i am happy with but don't know if the second is worth the extra volts.

4.5Ghz @ 1.300
4.6Ghz @ 1.385

is the extra 0.1Ghz worth the extra 0.085V

When going with temps do i go with the package or the individual core temps.
temps are 4.6Ghz @ 1.385v
Idle - Min core0 27c / Max core3 32c / package 35c
Load - Min core0 57c / Max core2 67c / package 57c

WOW! :eek: that sucks :( real shame

its may be down to may board are a setting this i have wrong but its a good low voltage clocker upto 4.6Ghz but then :(

all over setting are t auto, any change and the clock is unstable, i will have to have a play latter but i am happy at 4.6Ghz it will be better than the none k chip i replaced
 
What difference will it make? i have EIST disabled, and that in turn disables Turbo boost.
But i do have Enhanced turbo boost enabled. that forces the CPU to run at max speed all the time
 
ok i see what your saying now.

in my bios there is and option screen where you can set the power limit for the CPU. it was set to 125w with boost back in is not 1011w. that as to lift the lid on some over clocking
 
Pow!
there is life in the old beast

i think 5ghz is the max on 4 cores, i have vcore to 1.55 and it would not post so stopping there.

Edit
Stable 4.9Ghz @ 1.475v, idle 35c, Linx load 63c - 3d mark load 64c
my temps look to be more stable now, and i am 300mhz faster with volts

Gz, P4.... would be nice to see under 1.45v but only if you want to live on the safe side. But if that means only a loss of 0.1Ghz and going down to 4.8... it is not a big loss.

Anyway, now turn two cores off... leave everything the same but increase your multiplier to x51, x52 etc until no boot.

Lol i got 4.9 @ 1.445 :D, i will do two core testing in 5 any advice on what numbers to turn off or is it just ant 2.

Thats really good :) well done for finally getting there :D
p.s
(your welcome :D :D :D )

your temps are very high but its a good clockers, my temps are low and i have an okl clocker :p

@ Threepwood
Unstable at 5ghz, and would not boot and anything over 5ghz on 2 or 1 cores
