BIOSI Oc'd my i5 4670k cpu to 4.2 at 1.225 volt. and it looks pretty stable. But I am very new to overclocking and this was my first try. I have been running it for 2 days no throttling, good performance and no heat issues while gaming. in AIDA64 after 30 mins the max it hit was 86 degrees, average was 74-78. is this stable. yes I am running a phanteks cooler. everything good?
