Hey guys!

I have built a PC some weeks ago but i have a problem with it.
I have khx24c11x3k4/16x Kingston Hyperx RAM and Asrock fm2a88x extreme 4+ MB. Both of them supports intel xml profile up to 2400 Mhz. Theoretically. When i would like to use these profiles the PC freeze down with windows bluescreen. Sometimes under Windows, sometimes it chrashes before windows could be loaded. The north bridge also heats up itself to 60-70°C in some minutes.
I dont have VGA and APU is really slow on 1333 Mhz (atm its stable with "auto" setup on bios, that is this frequency). How should i fix it?
MB: Asrock fm2a88x extreme 4+
CPU: AMD a10 7870k
Ram: khx24c11x3k4/16x kit
Thanks for replies

Sure, thanks man, I rised NB voltage to 1,35, as you revealed the apu cant handle 2400 mhz so 2133 MHZ but it seems to be stabilized.
