When I overclocked my A8-6600K to 4.3ghz, it is stable. I overclocked it to 4.4ghz, prime95 said "Illegal Sumout : Possible Hardware Failure". So I raised the CPU voltage +0.025V and the error message still appears. My temps during both prime95 tests is between 50-60C.

My system:
A8-6600K
Kingston 4gb 1333mhz (overclocked to 1866mhz, voltage are in AUTO. I also tried overclocking the CPU to 4.4ghz with RAM in default settings, and still the error appears, but not in 4.3ghz)
Deepcool Gammaxx 300 with Deepcool Z5 Thermal Compound
Gigabyte F2-A88XM-HD3 (updated to F6 at the time of this thread)
Hitachi 500gb HDD
Corsair VS 450
Aercool VS-3 with 2 case fans

Also when I play games, it freezes when it is in 4.4ghz but not with 4.3ghz. I want this problem solved because Im planning to add R7-260X.

Update: I played Tomb Raider 2013 for more than an hour after I post this thread with 4.3ghz and my PC suddenly restarts without any error message. So 4.3ghz is also not stable.
