For 4.8, the ideal voltage is about 1.35v. Mine runs a little high and I run it around 1.385v.

Also, as I found this out yesterday, make sure VTT and VCCSA are not set above 1.2v. You shouldn't need more than 1.1v no matter what your clock is.

My VTT and VCCSA is set to 1.1v. My PLL is set to 1.65.

Those voltages are independent of CPU speed. So if you are at 4.2ghz, I would still have it set to 1.1v.

For VTT yes. That voltage doesn't really affect the CPU overclock.

I think typical 3930k requires more than 1.4V for stabilizing clock around 4.7GHz.

Also, if you're doing BCLK overclocking, adjusting VTT and VCCSA helps overclocking.
