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.

As of now I have Samsung, Hynix and Elpida memory cards but never ever thought about using same straps for different memory straps.

It is even easy to soft brick your card when you flash it with right straps but something goes south during the mod bios flashing.

I would not try what you are thinking but would love to listen about the results if you do

Yep. So basically you're saying I need to return my XFX RX580 because it's garbage for mining. Bummer. Thanks for the info.

No, I don't believe it's hopeless - the 2000Mhz stock clocked Hynix (H5GQ8H24MJR) is pretty bad, that's no lie. But it is NOT totally useless; it will do 30MH/s or so.

Wow. 30 MH/s would be incredible at this point. Can that be done as simply as any other card? Any guidance you could provide for a relative noob would be greatly appreciated... thanks!
