Hello guys, i really need your help. I have a pc build with the specs i wrote above amd i tried today to change ram speed (it was at default on 2133mhz). I update bios too and i reached at 2666mhz and when i tried to increase it at 2800mhz i got a blue screen (happened before too on default speed but i could reset system). So, i switched back to default settings but since then, i keep getting a blue screen and windows dont boot. I tried numerous times to reset cmos (with battery removal and bidging pins) but everytime the last settings are there and also windows wont boot. Can you please propose me something else to try? Thanks.
