Confused by Sandy Bridge overclocking

[burningforce]

not sure about the memory question

as for overclocking sandy bridge, all you need is either a "i7-2500k or i7-2600k" processor anda decent heat-sink fan. I do not have sandy but from what I read all you do is bump the "multiplier" up in the bios in increments of +5, then you load windows and test with overclocking tools. if it is stable and you want more speed, then you can return to the bios and up the "cpu multiplier" so more. Just keep in mind that whenever you raise the cpu and/or memory speed, you may have to up the cpu and/ore memory voltages.

safe voltages for the cpu would be a maximum of "1.35v" in my opinion (although the intel whitesheet says 1.5v) for 24/7 usage. I have seen forum posts where people have cpu voltage at 1.35v and got a nice 4.0Ghz overclock!!(though your mileage will vary).

here is a guide that is a work in progress

as for turbo, that is just an ability of the cpu to raise its speed to match the stress being put on the system by a game or other. I would not even worry about turbo and would advice turning it off if overclocking the cpu.
