[hackaday] Hack removes firmware crippling from NVIDIA graphics card

post #1 of 11
Thread Starter 
Quote:
If hardware manufacturers want to keep their firmware crippling a secret, perhaps they shouldn’t mess with Linux users? We figure if you’re using Linux you’re quite a bit more likely than the average Windows user to crack something open and see what’s hidden inside. And so we get to the story of how [Gnif] figured out that the NVIDIA GTX690 can be hacked to perform like the Quadro K5000. The thing is, the latter costs nearly $800 more than the former!

The article is very brief and vague, is the only thing this 'hack' does is enable 3 screens to be used in Linux?

Im not sure the dig at Windows users was necessary.

What does it mean? Does it mean that it is really only interesting for Linux users? It's not like you unlock voltage or more cores so your gaming performance would increase under Windows?

Yeah pretty much only for Linux users who want 3 screen enabled I believe

Well, for Windows users it'll let you use it with enterprise software that only supports Quadro/Tesla cards, as well as enabling 30-bit video support in the nVidia drivers (something that's only available in the Quadro drivers for Windows users - its a standard feature for Linux users of nVidia cards past the GTX280)

In Linux it'll let you do 3 displays with a single card, and enable some enterprise-only features in the drivers.

will this retain the 690's gaming performance or will it be shifted to a workstation/gpgpu card?

This is completely normal in the industry. One design is used for multiple SKUs.

Pentium, Celeron, Core, Xeon
GeForce, Tesla, Quadro
Radeon, FirePro
FX, Ax, Athlon, Phenom, Opteron


This mod may allow the drivers to support the card... but there are other hardware features that might still be unavaliable like additional memory or ECC.
Once again...
