Also I noticed that in CPU-Z, the voltage is varying between 1.288v-1.280v, mainly 1.288v. My LLC is set to Ultra High so does this mean I should increase the LLC level to 100%?
The variance in voltage is fine. Your LLC calibration simply reduces the Vdroop, or the droop of the core voltage, under heavy load. That's a place you can fine-tune later, once you have a good feel for how your system likes to clock. Ideally, you have LLC set as low as possible while remaining stable, but that's probably one of the last things you want to change at this point.
One thing you can do for a quick and dirty stability test initially is to do a Prime95 Blend customized to use 90% or more of your physical memory and reduce the time to 1 minute per test. That will let you cycle through all of the possible FFT lengths in a little less than 2 hours. If you're stable there, then you can increase it back to the default 15 minutes and after running for about 18 hours, you'll have done all of the FFT lengths possible for your CPU. (And you'll be in the super stable club.)
