Hi, so I overclocked my processor, and I just want a confirmation that everything is fine.
Core speed : 4600 MHz
Core voltage : 1.360V (Wasn't stable at 1.350V)
Temperature : Peaked at 92°C in the morning on Prime95, with the sun fully on the PC tower, but average is at 74°C
Prime95 : Ran for 8 hours and a half, still running, will keep it running until I get a confirmation here that it's fine and stable

Also, do you think that after that, it will be possible for me to overclock that RAM ? How high can I expect to get ? Is something like 2133 MHz asking for too much ? I somewhat know about CPU and GPU clocks right now, but I don't really know much about RAM.
