overclocking i7 2600k but voltage in BIOS/UEFI stock or auto?

post #1 of 6
Thread Starter 
I was going to re-overclock my system now that I have the temperatures straightened out a bit better and everyone says to begin raising the multiplier until it won't run on stock voltage anymore - which is fine but:

I fail to find anywhere where the stock voltage of the i7 2600k is listed. It fluctuates between certain values etc.....

and if you leave it on "auto" and raise multiplier , the motherboard will and wouldautomatically raise the voltage to be necessary to meet the newly input multiplier.

so I must be blind but is there a stock value people use instead of "auto" and continue to raise the multiplier based on that voltage? I think I heard some say it was 1.200? and not to exceed 1.350?

you should be able to go up to 45x multi with say ~1.3v (every chip and motherboard is different).

if you really want to find out the stock voltage for your chip, i believe core temp will reveal it to you.

342
see where it says vid? that's your chip's stock voltage.

thanks. I usually use CPU-Z but it fluctuates anywhere from 0.97 all the way to 1.10

Core temp will display your vid specific to your chip and that is what you should base the offset off of. Do what I did, start at plus or minus .010. Boot up, run a stress test, see where that goes under load, work off from there. A reminder though, go too much in the negative offset, and you risk having too low of an idle voltage and getting idle bsod. Im at 4.5ghz with -.010 at 1.34 under load. It was doing 4.6 with that voltage but for some reason my new gskill didnt like 4.5 so I backed down a notch. Golden now. Take a look at this thread.

edit: it also seemed like you were asking about manual voltage. Things chips are wierd/cool to me coming from amd where you are overclocked all the time and always running an o.c. voltage. As you know they down clock in idle state. What I did was set it to manual, go and input around 1.32-1.35 whatever your working towards for a 4.5ish overclock, then watch how it behaves under load, then you dont have to worry about your voltage acting all crazy. Once you establish whatever voltage your overclock needs, then you switch to turbo mode and just figure your offset to get your voltage you need using that method in the link i showed you. That worked for me.

I think you misunderstood.
CPU-Z shows you the voltage that the chip is currently running at.
Core temp VID shows you the "stock" voltage for your chip. every chip is slightly different you see.

I have CPUz and Core temp in this pic:

Though I don't get why CPU-z is giving ~ 1.100 as the voltage and VID on Coretemp is completely different. ( I know you said VID should be default voltage)

I do have the bios setup for 1.100 voltage in FIXED mode at 37 multiplier (3.7ghz) so the VID for coretemps seems out of whack, or is ~~~1.2XX the defaultt??
