Trying to get the best OC to mine RVN on Gigabyte RX580 4GB

[Shamlar]

Hi All,
I’m new in the mining world. I’ve been researching in the forum, and I’m not being able to increase the hashrate of my Gigabyte RX580 XT 4Gb (Elpida Memory) mining Raven (RVN)

Here is my OC settings now:

and here is the hashrate:

NOTES:
-I’m using Nanominer in this card, because I have other 2 AMD cards mining ETH with Teamredminer in the same flysheet.
-I’m using Flypool and I have not flashed the BIOS, just OC

Do you have any suggestions?

Thanks in advance!!
