AMD Overclocking help

[MagicManStan]

Hey folks. Brand new to posting on this site, but I've always have come to it as a guest for a long time.

So I'm torn about where to start with clocking my cpu on my mobo. I've put some time and research into it and I cannot get my cpu stable at anything higher than 3.7, and I've heard this thing can hit a stable 4.2 No problem

Here's my specs:
Motherboard: MSI 890FXA-GD70
CPU: AMD Phenom II X6 T1100
RAM: 16gb 1600hz (Timing 9-9-9-24-2N)

I have liquid cooling so heat shouldn't be an issue.
Life expectancy of the CPU isn't too important considering I will be getting a new one pretty soon.. going with intel next time.

I would like to hit 4.2 and be stable.. but I'm not sure where to start? Do I underclock my ram first or if at all?

Thanks for your support, I'm eager to see what this yields.

When you attempted do go above 3.7ghz did you raise the voltage incrementally as well?
