nVidia RTX Founders RGB LED Control

UPDATE: I flashed the eVGA 2070 XC Ultra BIOS (Non Ultra also worked) and it is working! Full RGB Lighting Control on the RTX 2070 Founders Edition, as well as 0 RPM fan mode.

If you want to try it for yourself, use nvflash from step 2 below and download this vbios: https://www.techpowerup.com/vgabios/204724/evga-rtx2070-8192-180919. Run the command .\nvflash64_patched_5.527.0.exe -6 EVGA.RTX2070.8192.180919.rom and reboot. Your card will reinstall new drivers, reboot again. Then you can use the eVGA X1 Software from Step 1 below to do all of your customization's.

So I figured out how to somewhat get this working. Steps to re-create:

1. Download eVGA X1 Software. This comes with eVGA LED Sync, which is what you will need to change colors. https://www.evga.com/precisionx1/
2. Download the patched NVFlash (renamed to n64 on my machine), non patched may work, but I'm using patched. https://www.reddit.com/r/nvidia/comments/9pxyix/patched_nvflash_55130_that_allows_rtx_founder/
3. Save the CIE (RGB Calibration Data) from the LED MCU: n64 --rdciegpuled RTXcie.csv
4. Flash it back to the LED MCU: n64 --wrciegpuled RTXcie.csv
5. Open LEDSync.exe from: C:\Program Files (x86)\EVGA\LED Sync and set your colors accordingly.

The card will be in somewhat of a limp mode right now, and you will have to reboot to go back to normal. (Happens anytime you are flashing with NVFlash). This also gets rid of what we just did, and now LED's are back to green and can't be changed until repeating the steps.

I have not figured out why this works, but I think it is possibly enabling the I2C Bus temporarily that the LED software is using to change the colors. Hopefully someone with more talent can chime in such as u/AthenaNosta

If someone has an eVGA RTX 2060 / 2070 with RGB support, I could really use your gpuled mcu firmware. Maybe by flashing this firmware, we can get this working. Otherwise I may need to try flashing the entire eVGA VBIOS. You can get this by running n64 --savegpuled gpumcu.rom
