P6X58D Premium - RealTemp Drops Overclock CPU Ratio to 24 from 25 when activated?

[sparkuss]

Hello All,

Decided to overclock my I7-960 to start playing Skyrim and I'm getting a weird behavior when trying to use RealTemp to monitor stress testing.

I can get straight into 4Ghz Win7 Ultimate no problems and CPUZ shows good overclock at 160x25. All good.

But as soon as I activate RealTemp, CPUZ shows the ratio dropped to 24 and the overclock drops back to 3.8Ghz.

I already ran some Prime 95 on the initial 3.8Ghz and it was OK temperatures wise before I tried to move up to 4Ghz.

Hoping for any clues on this behavior. Is this a known glitch on either RealTemp or the P6X58D Premium? Or RealTemp in conjunction with CPUZ. It's like RealTemp is hitting the MB to read and corrupting/changing that ratio from BIOS.

Here's the initial CPUZ at Win7 Boot

Here's CPUZ and RealTemp as soon as I activate RealTemp in WIN7:

Got an answer from RealTemp.

There is a switch in it for Disable Turbo. That will allow Realtemp to turn it off and that forces my downclock.
