Tweaker Turns GeForce GTX 690 Into a Quadro K5000








A user from the EEV forums has figured out how to turn a GTX 690 into a Quadro K5000 card, or at least make it appear so.
A user from the EEV forums has figured out a way to turn the dual GPU GTX 690 into a Quadro K5000 graphics card. While the K5000 might be a single GPU part, the modification to the GTX 690 turns one of the GPUs into a Quadro K5000 chip. The Quadro K5000 card is a business-oriented card that costs about twice as much as a GTX 690 and requires special drivers to run.
The user's motive to modify the card was that GeForce cards might support Nvidia Surround in Windows but do not support this under Linux. The Quadro cards, apart from different memory, are almost identical to the consumer cards. That supports this feature, which led the user to believe that it would be a driver issue that could be resolved by making the Linux box think that it was running a K5000 graphics card.


This was correct, and by a simple hardware modification on the PCB, the PCI Device ID can be changed so that the system drivers believe that it is actually running a Quadro card. We do know if the system sees the card as a Quadro K5000 card, but we cannot be sure about whether it actually performs like one or if it is entirely bug-free. Nvidia's Quadro cards carry ECC enabled memory that the consumer graphics cards lack.


Sadly, Nvidia hasn't responded to the story, and the forum posting where the process was explained has been taken offline.
This trick can not only be applied to this card; we've seen it in the past with other graphics cards. For example, currently, users could possibly utilize the same trick to turn a GTX 660 Ti or a GTX 670 into a GTX 680. The already disabled CUDA cores remain disabled though, so there will not be a full performance benefit. Taking a more interesting example though, perhaps we might see users apply the same process to the GTX Titan, turning it back into a Tesla K20(X) card and saving a lot of money in the process.
Tell us, if you had a GTX Titan or GTX 690, would you consider giving this trick a shot?
