hey i have a x48 ds5 mobo and it doesn't o/c any more,

in bios i change the settings to make an o/c of 3.4ghz but when it fails to reboot after the settings have been changed i reboot manually and the overclock hasn't registered with the os.

when it fails to reboot the system is still on, just no signal on the monitor, it stays like that for ages i left it like that for half an hour opnce just to test it and had to reboot it myself.

everything is back to stock now, cpu is at 2.8ghz

i have a q9550 cpu

please help no one replied to my last post.
