Overclocking my i7-2600K

[gizbug]

Right now I am running my processor at stock speeds and optimzed defaults in the bios.
I am thinking of pushing it to 4.0 or 4.2 which I believe is safe given air cooling.

Two questions. Is it simply me changing the Turbo Multis to 40x, LLC set to High or Turbo and thats it? Should be able to run on stock voltage, no? I heard I should set an offset,but not sure where or what value that should be.


Also, given my ram, should I set that to XMP Profile 1 or 2? Or leave it running at default?

I prefer LLC at its lowest setting, or off. On my particular board, turning up LLC increases voltage at all load levels, giving me a heavy-load voltage that is almost 0.075v (+75mv) higher than with it off. Gigabyte might have a better implementation, but I'm pessimistic.

You're right in that it's as easy as changing your turbo multipliers. 4.2 will be stable without any voltage adjustment on most chips, you might even get 4.4 out of it without touching voltage.

You may need to disable "package C-states", "C3", and "C6". I get BSODs unless I disable these three, though my brother's Haswell system only needs package C-states disabled for stability.

With my RAM, XMP Profile 1 is 9-9-9-24 @ 1.25v and Profile 2 is something like 8-8-8-22 @ 1.5v. I see little performance difference between the two, so I opted for the lower voltage profile.

Thank You.

I've been reading that there are basically 2 options with Overclocking. One is to just change the multiplier, the other is to go in, change all the Turbo Cores to the same value. My question is, if I just go in and change all the turbo cores, say to 42 (for a 4.2ghz overclock) would this be more efficient in a system?

By not doing this (I guess turning turbo off, and just changing the multiplier to 42) I am running at 4.2ghz 24/7. I really don't need this, as surfing the web doesn't need this. But it seems if I just overclock the turbos, then when a game or app needs the juice, it is there.

Thoughts and comments?

Even though I don't have this MB, it seems geared towards my processor, so this is the guide I've been reading http://hardforum.com/showthread.php?t=1578110
