I overclocked my 3770k to 4.2GHz and have been messing around with the core voltage. Currently, I have it set to 1.120V with an offset of -0.050. At idle I am recording only ~0.88V.
I have run Intel Burn Test and Prime95(only 15 mins) and get up to ~1.15-1.16V with low temps.
This seems a bit too low to me but so far it appears stable. I have read around on low voltages and it seems that nothing is wrong with a lower voltage as long as it is stable. I am very new to overclocking so I am still a little confused with the ins and outs of it all. I plan on running a longer test of Prime95 but haven't found the time lately. Any help/comments would be greatly appreciated!
