i cant run modern games at 90fps so it just results in screen tearing, you suggesting i get rid of g sync all together?Keep the refresh at its native 90hz. If you were having CPU problems at 4.4 and 1.3v something's up. Those chips should easily do 4.5.
ive just installed csgo, i use to play with on a 144hz monitor and even disabling g sync the games looks awful, its skipping frames, stuttering etc its awful even with g sync turned completely off and getting 300fps!
