Sony Vaio SVS13 / SVS15 series - overclocking BIOS for GT 640m LE users The Nvidia GT640m LE ("Kepler") which can be found in the Sony Vaio SVS13 series has an incredible overclocking potential. Unfortunately this is very limited due to VBIOS restrictions. This modified BIOS version will help you to unlock the full power of your GPU. The increased default clocks (3d) gives you additional performance without having to use any additional tools, but it als unlocks the software overclocking limit so you can go beyond the usual +135MHz limit when using software like Nvidia Inspector or similar, so you can push your GPU even further. NOTE: Since it seems that the boost function doesn't even work properly with the stock Sony BIOS, I decided to set the boost and default clock to the same level to avoid confusion about the non-working boost. This GPU runs incredibly low even with an impressive overclock, nevertheless I have to advice you to make sure your temperatures are okay, maybe slightly lift the system in the back to improve the airflow of reapply the thermal paste.

Isn't the VBIOS responsible for the GPU settings? Answer: How can I revert to the original BIOS? Answer: What exactly got changed compared to the original BIOS? Answer: *************************************************************** Remember, you are responsible for the changes you make on your system, flash at your own risk.

Howdy, I just got a MSI GT60 0nc 004 with the brighter screen, 16gb ram, BD drive, OCZ gen 3 128 SSD and had the heat sinks coated with arctic silver from GentecPC.com I just was hoping to learn a thing or 2 about my new workhorse!

New clevo 680M vbios on the way from @svl7 soon I think (he'll have to give you the details). But here's a preview (check the graphics score):
