Overclock Tweaking

[Nismo]

Hey guys, just got the below stats stable. I now have 2 goals:
1) Clean up the below stats a bit (lower anything I can)
2) Get my RAM from 1200 back to rated specs of 1333)

-If I change my RAM, what else increases with it? PCI? Whats the best way to get it back to rated speeds?

-Should I go higher with Uncore? Is there a benefit or would it cause stability issues?

-Anything look off with the below stats?
