Increase Defcon 2 bundle to 4.5Ghz

[Marleyman]

I have the DEFCON 2x - MSI X99A SLI Krait bundle:
Intel i7-5930K 3.50GHz @ 4.00Ghz
Motherboard: MSI X99A SLI Krait Edition (MS-7885)
Memory: Kingston 4x8GB (DDR4-2400) Quad Channel (256 bit) Frequency 1199.8 MHz
CPU Cooler Asetek 570LX 240mm High Performance CPU Cooler

This has been running for 3 months now and is very stable so I thought I would increase the CPU some more.
Has anyone taken this bundle to 4.5Ghz and if so, what settings are applied?
If not, what can I change to get there?

I will 'tinker' with those two later then.

Thanks.
