And one more question. How in the world are you hitting 4.5Ghz with only 1.140 Vcore? It takes me 1.300 for 4.5Ghz. Play a game WHILE running IBT and then see if your really stable. That's what I do and it works for me.
i have passed IBT on the highest stress level over 5 times and its been succesfull every time and ive been playing games like crazy the past two days without issues on 1.140v.
i can even get it stable for everyday use at 1.130v but IBT gets inconsistent results and sometimes my GPU crashes when im running both youtube and a game at once. 1.135 is honeslty probarbly good enough for everyday use and the few hours i ran on it everything was good but i just wanna be safe with the 1.140
Anyways i ordered another fan for my evo for a push pull config and a 200mm fan for my side case which is empty as of now
