Modders just changed GPU overclocking forever:
Modders have released two new tools that could change GPU overclocking significantly. OMGVflash and NVflashk have effectively cracked a security feature on recent Nvidia GPUs, allowing extreme overclockers to flash new vBIOS files to graphics cards.
About a decade ago, Nvidia locked down its GPUs. Graphics cards are governed by a vBIOS, which specifies such things as the power limit of the GPU, maximum clock speed, and parameters like when the GPU will shut down due to thermals. Prior to Nvidia's GeForce 900-series GPUs, extreme overclockers could flash a new vBIOS onto the GPU to achieve higher levels of performance. But Nvidia locked this functionality with an on-chip security processor.
The ability is returning with the new tools. Both were developed by members of the TechPowerUp forums independently, and the outlet says it has "hand-inspected the binary code" to ensure they're free of viruses.
Outside of tinkering, the tools can boost performance on cheaper graphics cards. Many brands sell a model close to list price and an overclocked model for slightly more. The only difference between the cards, in most cases, is the vBIOS file. The tools allow for cross-flashing as well, allowing you to flash a vBIOS from one vendor onto the card of a different vendor.
