Ok after running IBT for a full 10 run through this is my temps. max temp i saw was 56 but it stayed around 50 for the most part. ignore HW monitor, it is inaccurate for my chip as it only tells me package temp which is hugely offset as it says i idle at 56 whereas easytune6, my in OS bios temp monitor, says i idle at around 36. it also says my highest temp was 93, which is insane and my PC would shutdown by that point.
And after the test completed successfully, without any warning or shutdown due to temperatures.
So 4.5 is stable at 1.5v. im guessing its either A) my terrible PSU or B) my 4+1 power phase. if i cant get any higher then so be it, at least ive shown people in this thread that you can do a decent OC on a mid range board. Also speedfan Temp3 is my CPU, and it agrees with easytune6 for temperature
