So I was getting 27MH with my RX480. I just replaced it with a new RX580 and now my hashrate is only 21MH and won't go higher. This is using the same driver version and version of the miner (9.3), I have already attempted a clean driver reinstall with no luck. This hurts me seeing a newer and faster polaris card running quite a bit slower, it doesn't make sense. Any suggestions for why this might be?

It sounds like you were using a modded 480 and are now using a non modded 580?
What are your settings for the cards?

They both have the factory bios, I haven't touched them. The only thing I've done is raise the clock speeds a little higher on the core and memory on both. If I left both at stock, I'd have about 25 on the 480, but only 18 on the 580, it's just weird.
