New Build- BSOD and Lock Ups

Hello everyone, I built a new pc this week and am having some odd occurrences. For some reason when my CPU is oc'd at 4.4ghz I had two lock ups and a BSoD, so I rolled back to 4.0ghz OC and everything seems kosher. It's not a heat issue as far as I can tell I've monitored the heat in the BIOS and with CPUTEMP and it stays between 35 and 40c. There are a lot of "features" on my mobo that i think may be interfering. Anyone with the same mobo have advice on which options to disable to OC? Should turboboost be disabled as well?

Also I'm having something weird with utorrent, I've checked against my old pc and it's not my connection, but on the new pc I can't connect to any peers, so its impossible to dl anything. Windows firewall is off as well as windows defender....any help is appreciated.
