Googled it and over at a diff forum, they said with your board and using the multi the clocks won't drop. You have to OC using the turbo oc way

Interesting. According to Real Temp It dips to 2.4 from time to time. But mostly downclocking 3-3.5ghz...Task Manage will show this too. So I do get some downclock. But not what I hoped. Not too worried...temps are fine. Thanks for your help. Maybe someone will find out something different by the time I wake up in the am wink.gif

Try setting High Performance for the power plan, but changing the min power state to 5% and see if that does anything. Maybe it is "stuck" in High Performance. Also, have you installed the Intel Management Engine drivers?

I went to intel/support and it said I have the latest chipset driver...is this different?

Yeah. You need the chipset driver and the IME driver

here is the link for the IME (Intel Management Driver) driver:http://us.msi.com/product/mb/P67A-G45--B3-.html#/?div=Driver&os=Win8%2064

I know what you mean. Got 1 eye open and 1 shut. Time to hit the bed.tongue.gif

edit: I'll check the thread in the morning and see if you got it fixed.

It's late here but I think you need to use offset mode if you want the downclock.

With a manual vcore, it'll always pump that voltage so it can't downclock.

Good luck.

Well...either I can't find offset mode or there is none on this mobo. vdroop only has auto or low. Looks like I'm just gonna have to deal with it. According to realtemp, my cpu does down clock a bit...I'm now seeing 2.0ghz at times. But it's really all over the place. I'm pretty stable at 1.285 @4.3ghz. With good temps. Maybe I'll just call it a night for now. almost 5am! Thanks for all your help again. Maybe I'l wake up to a miracle and someone will have a cure all for me that doesn't involve a new mobo biggrin.gif

Offset will allow the voltage to go down at idle, but it won't have any effect on the clock speed. Even with a fixed voltage you can still downclock at idle.

Power Optimization – a Reality Check
http://www.cs.berkeley.edu/~krioukov/realityCheck.pdf

There is no reason to lock a modern CPU to 1600 MHz. A slow CPU is an inefficient CPU. You are better off letting your CPU run fast so it can get its work done quickly. When using the low power sleep states like C6, getting background tasks processed quickly will allow the CPU to spend a bigger percentage of time in the C6 C State where voltage and power consumption of the core is reduced to practically zero.

lowpowerc6.png

If a Core i CPU has the cores spending over 99% of the time in C6, there is very little to be gained beyond this. In C6, power gating unhooks the core from the power grid.

If you are using the low power C States like C1E, C3 or C6; RealTemp will correctly show the multiplier in your CPU going all over the place when lightly loaded. That's a good thing. You get excellent off idle performance, good stability when overclocking as well as very low power consumption.

Many Asus gaming laptops had some BSOD issues that were solved when the package C States were turned off so I disable the package C States in the bios. My 3570K at 4500 MHz has not had any stability problems when using the C3 or C6 low power core C States.
