I can see that would be a good thing for sales each product cycle. Is the VID hard coded into the chip, or is it part of the BIOS? What i mean is, even with just a few to work with, can they all be increased/decreased to give overall reductions/increases in power, or is it that there are only a few possible values that can be given to the chip in the BIOS? If it's the latter, it would seem nVidia really limits their ability to tweak their chips over the life cycle, but by the same token, it limits the customers' ability to do so, too. Let me reveal my noobishness and ask you some questions, please. If your 2d voltage/clockspeed is unstable, this means your card will hang every time you try to boot up. If you try to undervolt and screw it up, however, you're FUBAR. So you simply need to flash it back to the original settings and it should be fine in 3D again. When you reboot, it starts off in 2D mode, which is running at a lower frequency and voltage, usually one that's been determined to be safe at the factory. Being a mxm module card, its power draw is rated at 20 W maximum. The GPU is operating at a frequency of 475 MHz, memory is running at 400 MHz. NVIDIA has paired 512 MB DDR2 memory with the GeForce 8600M GT, which are connected using a 128-bit memory interface. If a card is clocked too high in 3D mode, it usually hangs or shuts down. It features 32 shading units, 16 texture mapping units, and 8 ROPs. However, I'd like to point out that BIOS hacks are much riskier to undervolt than to overvolt. I did some bios editing on my previous 7800 GT (good old Nibitor) to overvolt the GPU in 3D mode so I could hit higher clocks. Usually, the lowest (idle) clockspeed already has the lowest VID associated with it.
