As the titles says i have no signal to the monitor after changing my ram frequency. I have two 16 gig 1866 ddr3 ram. I noticed in my performance menu it was running at a lot less so I changed it in the bios. As soon as it reboot I have no display on monior. How do I fix this? Who should my frequency be set to given the ram that I have? How I get it to run proper frequency? How do I get signal back? HELP.
