Hey there I bought two 2208 and both of them got louder for some reason. I dont know why

I've been using then in ny Ramps 1.4 MKS Gen board.

Which mode are you running the TMC2208 drivers in? They are generally quieter in Stealthchop 2 mode than in spread cycle mode. If you are using spread cycle mode and they are noisy at standstill, reducing the TOFF parameter in the chopper configuration register may help.

Changes in supply voltage, configured motor current and motor inductance all affect the amount of noise produced.

I'm running them with MS1 and MS2 on VIO (256 Interpolation + 1/16 steps) and in legacy mode. I didn't reprogramm them or anything like that

They were really silent but now they do make a lot of noise.
