Nice Sergio. Your vcore looks about right for your 1.25VID chip (I have a 1.25 also). I need about 1.38 for 4.2Ghz and around 1.4-1.41 for 4.4Ghz so I'd say your on the right track.

I think these chips can withstand <1.45 24/7 just need to keep an eye on their running/load temps. But definetly H20 on CPU if using 1.4v+ 24/7
