Ok, unadvertently I can post something that might be of value...

I'm a noobie to mining so bare with me.

I am back to doing 30.5 MH/s ETH - Dual Claymore - Dagger Hashimoto

All I needed to do was set up "-strap 1" in configuration... so I went up from 27.1 to 30.5 MH/s

One note: I couldn't hold 2185MHz in these memories with that option set, but I'm apparently stable @ 2100MHz...

Needs further testing, I might get away with 2150MHz or so, which would easily give me 31.low MH/s, which is what I expected from this card (RX 590)

I can't imagine what it could do with a proper BIOS mod, unless what I'm doing is already maxing it out other way.

It's no problem to add K4G80325FC in PBE, but you need to test what Uber-mix will fit, I can send you also some of mine test timings which could fit also.
Send me your bios to monerobiosedit@gmail.com pls.

E-mail sent! Default BIOS attached. I'll await further instructions how to test this.

Small update:

With newest WHQL Adrenaline Drivers (19.12.2) I've managed to run VRAMs stable @ 2200 MHz, and I might try even higher.

It would be awesome if somebody could tell me how to manually adjust timings in a safe way, or have PBE update for these set of Samsung VRAMs (K4G80325FC).

Maybe for Christmas? 

Well, wow. That's definitely something bad with your card. At least I was getting only -10% than RX580, which is not extremely bad, as yours.

I wish I could get it to at least equal the HR I was getting before.

This card for some reason, though, consumes less power than my RX580, which still makes the whole deal equally profitable than before.
It is very weird, since these were supposed to consume more, not less, as well as perform more (not less).

Very, very strange.

I don't mind pumping it volts as long as I can get a decent HR... since I have free electricity... which is why I bought the 590, even though it was supposed to consume more power.

Definitely hoping this issue gets assessed by PBE creator, and also AMD, since it might be a driver issue, since RX590 is the last coin in the jar of Polaris, even if it is a brand new architecture.

It seems weird AMD would create a new architecture only for this RX590 product. I would imagine they would release RX650+ series in 2020 with this same architecture (12nm), and the RX590 is like a prototype, and we'll be getting optimized performance when those cards come out, and they optimize drivers...

But, this could totally be daydreaming on my part. I sure hope not.

We shall see.

Hi.

I'm running into an issue here. I recently bought an RX 590 (Gigabyte) and it has apparently a new set of Samsung memories (K4G80325FC) which are unrecognized in PBE 1.7.2 for the "one-click mod".

I would vastly appreciate if this could be made to my card, the BIOS mod.

If it is any help, it is a "Revision 2.0" model of the RX590 from Gigabyte.

Any extra information you could need I could provide.

I am only achieving 27.5 MH/s in ETH/ETC Claymore/Phoenix, when I was doing 30.5 MH/s on my old Asrock RX 580 (8 GB)

I am highly interested in making this work for these cards for everybody, so if you guys need any extra information about the card, just ask away.

Many thanks,
