Help! Hey Guys... A bit of a noob here, so greatly appreciate any help.

Setting up my 2nd and 3rd rig and decided to go with the RX580... Ended up with XFX RX580 8GB GTS Black Edition

Info on card:
http://xfxforce.com/en-us/products/amd-radeon-rx-500-series/rx-580-gts-8gb-dd-rx-580p8dbd6

I was only getting 18-19 hash rate out of the box... I can't get it past 20! From what I've read the 580's should be in the high 20's at least.

This was the best I could do... In ethOS I've updated the config...
Core: I've maxed out (according to specs) at 1425.
Memory: 2220

Is there anything else I should try?? Hoping to not have to return 10 GPUs...

You're supposed to underclock the GPU and tweak the memory timings with BIOS edits.

I picked up one of those XFX RX 580s as well, but it has two different types of memory. 4GB of type 1 Samsung and 4GB of type 2 Hynix (I posted a pic from the bios editor below).

So far I haven't tried to use the same straps across both types of memory...I have tried copying the 1500 from type 1 (Samsung) to only type 1, and the 1500 of type 2 to only the 2 (Hynix). I reflashed the BIOS for 1625 as well, but it was still unstable. I did several attempts with the 1625 Straps where I underclocked the GPU in Wattman but it didn't seem to help.

Does anyone think I should try to use the same timings "straps" for both the Samsung and Hynix? It seems really odd/tricky to me to have 2 different types of memory to overclock independently.

You have to know what memory brands you have. Use gpu-z. In bios you have 2 type but it use only one. Upload your original bios and upload screenshot of gpu-z.

I'll post the BIOS tomorrow night (my backups are offline on a flash drive and I'm not going to be back there until tomorrow).

(GPUZ says Hynix)

BIOS editor has a drop down menu where the different types are listed.

EDIT:
Default BIOS for the
XFX RX 580 Black Edition GTR

The timings list both Samsung and Hynix memory. GPUZ only lists Hynix, so maybe I can just ignore all of the type 1: straps?
