I have to disagree slightly with the above.
Overclocking should be done manually, gradually and with understanding of each of the settings. This will get the best results. However overclocking is rather simpler than it used to be, and you can get reasonable results with remarkably little knowledge.
As an example, set the following
qpi to x36
unclock to x16
ram muli to x8, timings to c9
vdimm to 1.66V
qpi voltage to 1.3V
vcore to 1.3V
turbo off, load line calibration off
This will leave you with ram running below spec, processor at 2.66ghz. Run ibt/prime95 for ages to check it's stable, I'd be astonished if it wasn't. Increase bsck to 150, retest. Then increase bsck 5 at a time, testing each step. When the tests fail, go back to the last stable bsck and you're done. What frequency you hit from this is a bit hard to guess, should be 3.8-4.0 ish.
I'll reiterate though, researching this and spending time on it will achieve significantly better results. Not least that a lot of settings are system specific, cpu pll, pci clock drive, cpu clock drive, qpi pll all have to be set on an individual basis. In my case 1.7, 800mv, 800mv, 1.14, but for you these values will not work better than defaults.
