2500k OC help

post #1 of 7
Thread Starter 
This is my first oc and i would like to just get it to 4ghz right now.

My question is what should my settings be in bios?

I looked at this guide (http://www.clunk.org.uk/forums/overc...beginners.html) but it doesnt mention changing options such as LLC to ultra high like ive seen before or turning off turbo mode..

Can anyone help me out on this? ofc +rep like always

Well, no processor overclocks exactly alike so your best bet is to decide whether you want Offset or Fixed voltage(usually doesn't make much difference other than extra power usage on idle).

Next, just start raising your multiplier up to what you want and test stability as you go. Also set your RAM to its optimal settings. When the CPU becomes unstable start upping the voltage at minimal rates. I usually use IBT or Linx With Updated AVX Linpacks for quick tests then find the clock I want and then run Prime95 for extended periods.

you may wanna look at the official sandy bridge 24/7 stable overclock club to see what others use. Both I and the posted above are members.
If you're only looking to go to 4ghz you can leave most things on auto.
Set core multiplier to 40 and leave bclk at 100. If you're using manual voltage try 1.26v at first then if that's not stable just bump it up in intervals of 0.005v.
LLC on high will do and bump up cpu capability to something like 120%

I am not saying these settings will work for all 2500k cpus, as they wont but it's somewhere to start.
Hope this helps.

What exactly does cpu capability do?

I cant remember exactly what it says but when in bios it gives a description, it's something to do with the ability to feed the cpu power. Basically when you're overclocking that high you could do with bumping it to 120%.
Hope you found all this helpful

What I would do is the overkill technique:

Raise the voltage to 1.35VCore and set the multi to 40. Of course set all your RAM timings to their normal and the RAM speed to it's default. Then just keep running stability tests and lowering the voltage until you get to the lowest stable voltage.
