Help with CPU speed fluctuation with HT on please

[LRBS 946]

Should I be looking for a new MB?

I finally found the problem related to what I was complaining "Windows AVX was causing measurable FPS drops when it kicked in". Actually there is recent windows update that is creating CPU SPEED fluctuations based on AVX coding inside windows overriding MotherBoard settings.

Unfortunately I wasn't able to find which update is, I used recovery option on Settings and it did not say which update was rolled back to. 

Now the CPU Speed is steady as a rock, no fluctuations at all in any conditions.

Now I turned off windows update, who knows what kind of other problems will trigger this.

Maybe somebody knows which recent windows update has incorporated "Windows AVX" coding and how to block that update?

AVX is an Intel instruction set.
