Yeah. It depends on the voltage of a particular overclock. More voltage = more stress on VRM's.

Here's my Specs:

Gigabyte 970a-DS3P with Deepcool NBridge 8 as NB Cooler
2x4 1866 Kingston HyperX t1
AMD Asus HD 6990 Awsum bios default
Cooler Master Silent Pro M2 720w Bronze cert.
1TB WD Caviar Blue
500GB WD Scorpio Blue(files)

I play dota 2 in general and from 120fps it drops to 40+ fps because of CPU downclocking, i cant play BF4 or CPU extensive games like this because im afraid that will do something with my performance, i render videos as projects.

that's pretty much everything.

I've disabled cool n' quiet technology, so its out of the suggestions.

THANKS IN ADVANCE.
The problem you are experiencing is called throttling. it occurs when part of your CPU or power system is getting too hot. Now looking at your motherboard and the fact that it is only a 4+1 phase already spells trouble for you. Now compound that with the fact that you have an AIO cooler (so likely little airflow around the VRM area) and you have an intense (for the MOBO) 4.7GHz OC and you can see where things are going wrong. Now its not that 4+1 phase mobos are bad. But they just really tend to struggle when trying to take the 8 core Vishera's past 4.5GHz. Now there are 2 things I want you to do.

1. It is time to dump Core Temp. (The relationship was never going to work anyway. wink.gif ) Get HW Info64 OR HW Monitor. I want you to fetch me temps for "Package" which is the temperature your CPU die is reaching, and "Socket" temp. This is the temperature of the actual socket of the processor and usually the temps that your BIOS will report. The maximum temp for Vishera cores are 72C. However I have seen some hitting WELL above that and they are fine. When it comes to socket temps, most motherboards start to throttle at around 70C.

2. BEFORE YOUR MOTHERBAORD EXPLODES. Put a fan near or on the VRM's to get airflow to the VRM's to help cool them down. I use the 70mm stock fan to do VRM duty. You will also need a fan on the back side on your socket. Cut a 120mm hole on the back-sidepanel and place a fan of your choice there. This and a VRM fan will most likely solve your problem.

Unfortunately, this isnt helping your throttling problem either :

The ripple values of the Silent Pro M2 720W are far less impressive, as they're the worst of all the PSUs in every load test. Its ripple values range from 61.2mV at 200W to 115.4mV at 700W, which is only just within the 120mV limit. If you're a frequent heavy user or are interested in overclocking, you'll likely want to avoid this PSU.

So i did what you said, i added a fan on the vrm, i plugged a switch with 5v and 12v, and switch it when i need it. ill try it later and upload some picture of it cause i cant upload now and i dont know why, i installed hw monitor.
