after 2v Sams stops scaling on air vivi, highest i ever boot air is 2900 C9 tight 2.05 and pass 8m, cold gave them more stability and max out close to 3ghz with nice sticks under cold -10 to -50 nothing change here with my sticks, i am more stable when normal air but i guess good temp for IC is about -10
tried them 2.2/3 Cold----Air 2.05 never killed one.
