Uno, dos, Quadro
So what exactly is going on here? This page shows instructions for making minor modifications (soldering some resistors) in order to turn a GeForce 256 card into a Quadro card. The Quadro is basically a more expensive GeForce sold into the workstation market. Apparently, making these minor changes increases performance in measurable waysthe page has benchmarks to prove the point
But how? Are the drivers reading the card ID differently and doing something to enhance performance? Is the chip's BIOS seeing a Quadro and setting a different clock rate? My theory: magic resistors.
