i ave a asus z68-v pro MB with my 2600k and just starting trying to overclock and found an issue. If EIST is on my multiplier will not change. Not matter what I set it to in the bios its max is 34 and will throttle down to like 16 when idle according to cpuid. With EIST off I can change the turbo multiplier to anything i need upto 59 and it changes fine but it will not throttle down at all at idle just sits at whatever I set it to. But as soon as I enable EIST the multiplier goes back to its max of 34. Anyone know why this is happening I thought you should be able to OC and use EIST
