with .050 offset what are your actual voltages in cpuz also how are your temps looking
Sounds a bit defeatist but id be tempted to just run with 4.2 at - .005 the difference in speed and work done going from 4.2 to 4.4 will be tiny especially when you start getting isues
I don't use offset FYI, I prefer to know what the voltage is set too, call me old fashioned
