Sapphire RX 480 NITRO Hashrate

I've read a lot of postings on the forum but I haven't been able to replicate anything to get over the 23 MH/s mark. I'm using TRIXX and if I put my memory clock over 1834 it crashes. Here are my current settings for 22.6 ave MH/s at 90w of power from the GPU

1100 GPU Clock
1834 Mem Clock
25% power limit
-96 mV
fixed fan 45% (53 degrees F)
