780/290x Lightning LED Color change?

[AMD Lover]

So I know you can't change the color of the LED through software but the header for the LED plugs into the PCB and I was thinking. Do you think it would be possible to take out or wire together a few cables to achieve only one color? For testing you could simply take wires and shove into the end of the connectors and then touch to the contacts to see if any combination achieved only a single color....

It solely depends on the LED most use multiple single color LED so you would need to change out the whole LED to change it's color while others use RGB LED so if you take out other wires you would be missing parts of the spectrum leaving it with a single color going at different brightness to trying to replicate a color within that spectrum but missing two other LED's.

 

Are you trying to change out the LED's on the GPU, if so do you know if they're RGB LED's?

So, they change from green to blue to red based on power usage. I wanted to keep them blue (Best would be white but I would have to add my own I think) so I figured I could put some tape or something over a few of the contacts to make them stay blue. Like I said up there though the color I really want it white but I haven't bothered to peal back the tape to see if the LEDS are RGB or how they are mounted or anything. I won't have my new card tell Tue (Had to RMA) so I can't mess with it tell then.

If they change based on temps it may be a bit more difficult especially if they're RGB since most manufacture's use SMD LED's to save on costs. I assume there is a short length of power cord that comes from the GPU and goes to that LED module, so theoretically you could take off the module and directly take power off the power pins and as long as it's ~3.0V you can add in a resistor and any LED color you wish at that point.

Well theres a good chunk of wires that come out from behind the tape (5-6) and then they plug into a header on the PCB right by the fan LED lights.

Yea I would assume a fair number of them since there would be a ground, power lead and three others that control or vary the voltage to change the colors on the RGB LED or turn on and off each single LED. Once you get the replacement card if you could  carefully probe each wire using a multimeter and find a ~3.0V line that is always on even when the temps change those are the two wires you want to use to power your replacement single color LED with using an inline resistor.
