pour modder un bios c'est facile d'apres thalanix :
Method 2 (DIY)
This section is if you don't trust my BIOS and want to make your own, or don't feel like waiting for someone to make it.
2.1) Using MMTOOL (found on your favourite site, _not_ here), extract the first module 20 (Device ID 064A, Vendor ID 10DE)
2.2) Load the extracted module in NiBiTor 4.8
2.x) NO LONGER NECESSARY BUT HERE ANYWAY: In hex view, the clocks are located at these addresses 0xCF68 (core), 0xCF6A (shaders), 0xCF6C (mem) (using 2-byte words)
2.3) Change the values to your liking.
2.4) Save as a new file (overwriting didn't seem to work for me)
2.5) Back in MMTOOL, replace the module and Save As
2.6) Uninstall the drivers
2.7) Flash with EZflash
2. Load "User Defaults" in BIOS Setup
2.9) Reinstall whatever driver works best. I use 185.20
