A question about overclocking a 2600k if you would be so kind...

Hi Guys,

I am a bit new to overclocking and have a couple of questions about overclocking a 2600k on a Asus P8Z68-V PRO motherboard. I have managed to overclock my 2600k to 4.6Ghz (2 Hours prime stable, 20 passes on LinX 0.6.4, many hours of games and general use) at 1.36V, reaching max temperatures of about 71, usually its around the 65 mark.

I am going to try to get it stable at lower voltages, but havn't got round to it yet, as I'm still early on in the process.

Is there anyway to make it so the cpu Voltage is dropped when the processor is idle (to reduce the temps) if the voltage is manually set in the UEFI Interface? At the moment my CPU sits at around 42°C which is a little hot? At stock speeds it sits at low 30's. I'm using a H60 cooler.

I know if you set the CPU voltage to auto it will do this, but then when it ramps it up to 100% load it sends the voltage way pass the 1.4v mark (which I dont really want to do due to the impact of the lifespan on the processor).

Or would you recommend gradually lowering the voltage until it becomes unstable to find the perfect voltage, and seeing what the temps are like then? I am going to try 8 hours prime tonight to see if its fully stable.

Ok Sorry Guys, with a little more digging I realise this is the Offset mode on the CPU Voltage setting.

I'm guessing that say my CPU Voltage is 1.4v stressed setting a CPU offset of -0.1v would take it down to 1.3v stressed, effectively set a maximum voltage of 1.3v for when the CPU is stressed? After doing a bit of research I see that it does it to your idle voltage as well.

Does anyone have any quick guides as to what to set it to? Do you guys recommend using it or do you stick to the manual (fixed voltage), or do you leave it on auto? When left on auto my temps go quite high (high 70's) and the voltage goes up to 1.43v. Maybe I am being a bit ambitious with my overclock and should try and set it lower?

Thanks for your help, sorry to spam up the boards, you guys must get 10 of these a day....

Cheers for the help guys. I am going to read up on it a lot more. At the moment I am just keeping a manual voltage at 1.36v for 4.5Ghz which is Prime stable 8 hours. I will revisit the offset mode later when I know a little bit more and have more time to play with it.
