So here it is : I'm very happy about my Dark Hero MB for gaming and the rest, but about christmas I started to turn my PC in a lightshow, for the kids. I had 120 leds across 4 devices (3 Gen 2 on one header, 1 GEN 1 on the other). The specs and manual say that the motherboard can handle 500 addressable leds. I say fine. I buy a 300 Leds strip. I plug it on one header.... and it will only lit a total of 120 leds. If i put the other GEN 1 through a splitter on the same header, I have those 30 plus 90 leds on the strip. If I put only the strip, it lights up 120 on the strip. If i mix GEN1 and GEN2 on a header, it corrupts the lighting and i get even less leds lit. Back to all GEN 1 on a single header, how do I get to use more than 120 leds ? Why does it consider different devices a single device ? (It doesn't do that on the GEN2 devices, the three fans are considered 3 independent devices of 30 leds each). How do i get to use the advertised 500 led if i can't have more 120 / addressable header ?
