Hello, coul somebody help me to solve my problem with two GPUs by mining ZCASH?
I have two GPU in my PC, RX 480 8 GB and R9 380 2 GB. RX has 300 H/s but R9 only 24. Where I make a fault? Could you help me? Thanks...

Need way more information than this:

so lets start off with the basic questions:

O/s (home or pro)
make and model of each card(s)
drivers version installed (ARE YOU SURE?)
mining software running and version
Post your config file (if needed)

What is the question or problem you think you have, and be detailed.
