Few things.
As far as i know im the only one with a modded vbios for the Assu GTX 670mx. I did not make it for everyone it was made for my card and runs some pretty aggressive memory timings so chances are if you flash it you will brick your system and will be spending a few hundred to replace the GTX 670mx since it will not be covered under the warranty. Its also not for the public it was made to push the G75VX to its limits in some bench marks to show that the system can do when its maxed out to 100% like i did with the G75VW a few months ago.
If your card can not pull 700 on the core stable you have power issues or you are the owner or the worst GTX 670mx i have ever seen. It runs fine at stock clocks so the gpu is fine.
Stock volts the GTX 670mx i have hits 810 on the core stable. Pretty far from my GTX 660m that did 1200 on the core. With a volt mod and running 2 G75VX psu's modded "Typical for what guys do with high end GTX 680M SLI rigs" I can push the GTX 670mx to 1150 so far. Still early with it i expect to hit 1200 temps right now at loading at 78c i'll be switching thermal paste in hopes or getting it down to about 76c. But i will have a big posting like i did for the GTX 660m here with what drivers i use what clocks i got stock and volt modded.
Also keep in mind that the system was made for the 45w gpu. They just upgraded to the 75w so the extra headroom we had to oc the 660m was eaten up. Overclocking the GTX 670mx is going to be pretty hard on your voltage regulation circuits and what not and i know it can handle about 85 or so watts i dont know how it can handle around 100. So i guess we will find out. Sould have all my testing done in a week or two.
