What is your motherboard and cooler? 1.45 is kinda safe but not recommended. I personally stick to =<1.400v for daily use.
Use manual mode to overclock, not offset. Once u find your stable manual voltage u can try to change it to adaptive. Note that high overclocks doesnt like adaptive voltage control and you may experience instability in games. If so you can try to increase voltage even more but i would personally just go for manual.
Also make sure that your temperature for 24/7 doesnt exceed 80C at average. Short jumps over 80 are fine tho.
Thanks for answering, Im using Asus Maximus VIII Hero and NZXT Kraken X42 as Cooler. Temps seems to be fine going from 60- 75C while playing, and 90C(maybe alittle high) on stress test. Was a bit worried about the Voltage use.
Thanks again for the advice, think i will stay away from adaptive and go with manual for the stability then
