Help me flash & overclock my 680M, please! (Sager NP9370)

Hey guys! I've done LOTS of reading on flashing the 680M to achieve higher clocks. I want to do this, but I don't know what the best route is. I need down-to-earth information on this stuff. I've read a ton of information on this, and the information is cluttered in my head. For example...

Can I flash a third-party Clevo VBIOS without having to worry about my laptop being a Sager? The reason why I ask this is because Prema's comment stating

What glitchy problems will I run into when installing the third-party VBIOS? For example, there's people complaining about display output from DP & HDMI not working because of the VBIOS flash. Complaints also include trouble updating to newer drivers. Another complaint was a person that said "My issue is, that I can't use Nvidia Control Panel (Keeps telling me that my screen is not hooked up to a Nvidia GPU), driver 340.52 wants to install all the time from Geforce Experience and the 680M has a code 43 error in Device Manager. Plus GPU-z and CPU-z don¨t show any voltage or CUDA/PHYS-x or anything."

Another thing that irritates me is that people keep talking about different voltages for SVL7's VBIOS. There is only one download link for one SVL7 VBIOS, and I have no idea what voltage that VBIOS is set to.

Can someone help me out here? I can make a bootable DOS USB and load a VBIOS. I have step-by-step instructions for that, but the information for everything seems cluttered, and the VBIOS seems glitchy and doesn't seem to be fully compatible with the rest of the system.

Help?!

 

The video bios (Vbios) is identical on both clevo/sager. There is a handy guide for kepler vbios flashing over at the tech inferno forums (with files). The files require 5 forum posts OR a donation to be downloadable.
