In the weeks and months before the launch of AMD's Radeon RX 7900 XTX, enthusiasts were hoping AMD's graphics cards could go toe to toe with the best Nvidia had to offer. In the end, the RTX 4090 took this generation's gaming crown. However, it's clear AMD made a conscious decision to limit the power consumption of the XTX, leaving us wondering just what AMD's Navi 31 chiplet GPU was ultimately capable of.
That question has been answered, thanks to a post by user jedi95 in the AMD subreddit. Jedi95 took an Asus TUF Radeon RX 7900 XTX and modded it to eliminate the card's power limit. The mod involved connecting an Elmor Labs EVC2SE to the I2C bus on the GPU's PCB.
