NVIDIA cripples firmware on their Video Cards - This 8-Bit Life
NVIDIA has some explaining to do here. They sell two separate video cards, the consumer level GTX690 and the professional level K5000. Both of these cards utilize the same GPUs but the GTX690 is simply a crippled K5000. It’s very frustrating to see NVIDIA treat customers this way. Moreover, they know the sort of people that they market to, they couldn’t have expected that their hardware would not be probed at some point.
They accomplish this by changing the analog values that determine what model the card represents itself as.
A user named Gnif on the EEVBlog forums has found a way to unlock the hidden power of his GTX690 by desoldering one resistor and soldering on a 15k and 20k on specific pads of the board.
So why am I irritated by this? Because the difference in cost for the cards is about $800!
