M5A99X EVO R. 1.0 stop image

Previously described the problem in memory as did its crackdown and thought the problem for her. Installed in motherboard FX 8320, while the system was in stock there were no problems. Decided to overclock, the kernel v 4400mAh.1.325, the controller 2600 v. 1.275, HT 2600 RAM 1866 (v.1.65 is a drain). During the tests the system is no problem: Aida, prime and memtest. But in games periodically stop image for 1-3 seconds. Tried with string to RAM 1600MHz the problem is, but if at the same 1600 supply voltage to the processor and controller in the Car, it hangs disappear. After tried removed the overclock and set everything to stock, but raised the RAM up to 2133 MHz at 1.675 V. and the quests appeared again 1-3 seconds after 5-10 minutes, sometimes throws on the Desk, as if a simple PC can simply hang the picture on the desktop, it only forces a restart. Tried with different power supply 550 and 600w, and changed his Rx to GTX 580 1060, freezes remain. As if everything points to the motherboard may be overheating or bad power, the motherboard did not seem to be the worst. I would like to solve the problem, without overclocking the system nor pleased with the performance.
