I have a Core i5 760 2.8ghz and a P7P55D-E XL Motherboard.
I tried following this guy's settings But despite us having the same hardware, when I click save and exit the computer just sits there, still running but the screen is black. I waited a minute or two to see if it would restart but to no avail. So I turned it off manually, turned it back on and then I get a message telling me my overclock failed and I need to reconfigure my settings. So I tried raising the voltage to 1.24 like he suggests in the video but still it refuses to boot back up, it always hangs on the black screen and when I reboot manually I get OC failed.
If it's important this is the ram that I have. I also have a 750w PSU and a GTX480 if that matters.
If anyone knows what might be the problem please let me know.
I have the same cpu and first off back down on the clocks. Put the base clock at 162 and keep the 1.24v on the core. That will put it at a solid 3.4ghz with 3.56ghz turbo. If it isn't stable at that then there could be a defect in the board such as the power vrm not working as well as his or you didn't get as good of a sample as he did. Power consumption really begins to spike after 3.4ghz.
