Permanently overclocked my NVIDIA GeForce 8600M GT (Dell Inspiron 1520)

I seem to be on a Video BIOS flashing spree. First my Radeon HD4670, and now my GeForce 8600M GT. Well, I thought of breathing new life to my ageing Dell Inspiron 1520 and here is what I accomplished...

I downloaded an overclocked version of the NVIDIA GeForce 8600M GT BIOS from techPowerUp. After a few hours of research I came to a conclusion that 490 MHz core clock and 490 MHz memory clock should be stable on this system. For some strange reason Dell used DDR2 memory for the video cards on the Inspiron 1520 which severely bottlenecks the performance. Overclocking the memory and the GPU can do wonders. I downloaded the Windows version of the NVFlash tool from techPowerUp and flashed the OCed video BIOS.
