System won't post with overclock after OS restart

From what I understand, the problem I'm having is quite strange. My system works fine when I run the CPU at stock speeds (3.6 GHz), or when I overclock it to 3.7 GHz. When I overclock it over 3.7 GHZ (3.8 or 3.9), the system posts and I am able to boot into Windows. Running Aida64, the overclock appears stable, and temperatures are right around 50C. From within Windows, I am able to "Shut Down" the system, and it will turn back on without a problem. However, if I "Restart" from within Windows (and if I'm using an overclock of more than 3.7 GHz), the system will refuse to post, and I have to reset the CMOS via the motherboard jumper in order to make it boot again. I'd greatly appreciate if someone knows what is going on and could explain how I might be able to run the CPU with an overclock greater than 3.7 GHz while being able to restart the system from within windows. Thank you!

Additional Information (potentially related):
The stock voltage on the CPU is 1.375 V. I am able to increase the voltage to 1.3875 V, and the system is still able to post and boot. However, if I set the voltage to 1.4 V, the system will not post, requiring me to reset the CMOS.

A lot of strange things may happen when you OC and may depend on the way you OC. First, make sure you have right BIOS version, it's a new platform and BIOS updates happen often, sometimes newest one doesn't mean it's best one. Second, try different LLC settings instead of set values.
