Asus Maximus 2 Formula 4.2ghz OC Help

I was running at 4.2 for the longest time but couldn't get it to be stable for the life of me, I have since knocked it back down to 3.8ghz and work up again from there.

My current BIOS settings were the same that I used for the 4.2ghz except my CPU Volt. was 1.4v and I was using a 9x467 setup.

Any advice would be much appreciated!

Here try this, you will need to adjust vCore to your CPU and depending on your ram you might need to run 1:1 PL10
