Didn't know that MUSIC it's multi-algo, but I prefer CN algo because low: heat and wattage
I'm using xmr-stak but I it does not have the gpu-thread option like SGMiner, the OP said that increasing that option to 2 gave a little more h/s, appart from the bios mod
I have not played with the xmr stak options, I just let it by default and in fact the cards are 1000/1750 since I'm working so not much time in home to check, only with teamviewer
BTW what it's your hash in ethash, cn-v7 and cn-heavy?
No, I meant that I use my 2GB (16CU) RX 560s for both Ethash and CN, but for Ethash I am restricted to MUSIC or UBQ because the DAG files still fit into 2GB. Right now they are mining MUSIC and doing 14.3MH/s per card, which is a little over half what a 4GB RX 570 will do, but at much less than half the price (at least that was the case when I bought them back in Dec/Jan).
As for the CN forks, I use xmr-stak 2.4.2 because it performs the best so far and is very stable. It does not perform well "out of the box," so to speak - the config files it generates (amd.txt and cpu.txt) need to be heavily modified. My amd.txt file modified for just 2 cards is shown below. If you have more than 2 cards then increment the index parameter for each additional card but copy everything else (assuming they are identical cards) and put those lines before the

I get about 495H/s per card with this congfiguration in CN-v7; I have not tried the other forks because I am not interested in any of the coins that use them.
