OK, so Amazon decided to send me 4 RX580 that I ordered back in july/august Smiley
Since then I built only nVidia mining rigs, but now I decided to give it a go with RX 580s, but it is completely new territory for me...

For now, I got 2 XFX RX580 GTS 8Gb XXX editions, one with Samsung and one with Hynix memory.

The cards have a small microswitch for dual BIOS, so I switched to the so called mining BIOS. The thing is I'm not exactly happy with the card's performance, as I understand they should hit 30 Mh/s easily while solo mining with Claymore

Here are the facts:
- I installed the latest radeon drivers, and made sure that it was set to compute workload (I'm using Win10 and Claymore 10.1 btw.)
- I didn't update the BIOS yet, since they are supposed to have Mining BIOSes already (As advertised by XFX)
- The one equipped with Samsung RAM can reach 30Mh/s with heavy OC (1250/2230, and no undervolt). Undervolting to 925mV in MSI AB drops performance to 28,5Mh/s)
- Hynix card is even worse, around 27Mh/s and setting power limit or voltage in MSI AB doesn't seem to have any effect, it stays above 1000mV (1150/2200).
- I checked the BIOS of the card with SAMSUNG RAM, and it has the same strap for 1750 and 2000 so I don't know how could I finetune the memory timings
- Right now the 2 GPU's are in my gaming PC, the top one is getting pretty hot around 75 celsius (this won't be a problem once I move the cards to an open air rig.)

Any suggestions/tips would be welcome

has anyone seen an update on xmr-stak yet? I just don't see a download version or am I blind?

 Grin

You know that's BS right?

I have yet to see a GPU straight out of the box that hashes 30Mh.

Undervolting shouldn't directly affect hash rates. It would either give you a black/blue screen or crash your rig instantly. Fluctuating hash rates are the effect of improper/over OC.

And if you think your 75C cards would magically come down to 60C once you've put them in an open-air frame, you're mistaken. Best they would do is drop it down to 72-70 - but that's still one hell of a temperature. Dial in your undervolt and you'll drop it down to 62-65C.

I mean all this hell of modding bioses, patching drivers, undervolting, memory types, power limits, fine tuning all this shit, endless bugs... considering all these things constantly changing... and all of this to get at most 30% more profit from mining.

You are like random tech words generator...

Let's do some math. Stock RX 470 doing like 20MH/s, with modded bios you can have more than 30MH/s so that's 50% improvement in gains, considering you will also undervolt and save electricity costs, let's start easy with 125W stock and 100W modded that's saving 20% on costs.

Ciao Hello Matthev ... First thank you for publishing this information!
I have two old RX-460 OC 2G Sapphire dual fans, unlocked, I thought of upgrading the BIOS and using the one of the RX-560 and optimizing the BIOS for mining. Do you think it is possible and above all it makes sense?
I'm currently down to 320 h / s in cryptonight sgminer-5.5.5.

I also have an unmodified 4G Sapphire RX-570 that mines at 590 h / s sgminer-5.5.5
Does it make sense to try to modify the BIOS here too?

Hello Ciao Mattthev  ... Innanzi tutto grazie per aver pubblicato queste informazioni!
Io ho due vecchie RX-460 OC 2G Sapphire dual fan, sbloccate,   pensavo di fare un upgrade del BIOS e usare quello delle RX-560  e ottimizzare il BIOS per il mining. Pensi sia possibile e soprattuto ha senso?
Attualmente sto minando a 320 h/s in cryptonight sgminer-5.5.5.  

Ho anche una RX-570 pulse 4G Sapphire non modificata che mina a  590 h/s  sgminer-5.5.5
Anche qui ha senso provare a modificare il BIOS?

There's definitely a learning curve, but once you understand how to do it, you can just set it and forget it.

He doesn't explain how to fix the table pointers after you delete the extra bytes from the padding, but gupsterg @ overclock.net has a video for that here:

RX 570 all the way. RX 460 I don't like them, but yeah you can try it I think the released Hynix timing should work with that, not sure if you have Micron how it will work.

Hello everybody, how is it going?

I own AORUS rx 580 8 gb, hynix, H5GC8H24MJ (H5GC8H24MJR in srbpolaris), using 777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB0300000 01B162C31C0313F17 timing strap in 2000 and 2250 mhz.

I've set 2090/1225 and I get 29 mh/s with 0 errors. If I set higher memory clock I get some errors.

I would like to get 30 mh/s can anyone help me, maybe suggesting a better timing strap or if not possible, with a tutorial on how to make a custom timing or any other advices that allow me to get a better hashrate, please?

Has anyone managed to reach a better hashrate with 0 errors with this card?

Thanks
Happy mining

Hi guys. I was wondering what does it mean if HWinfo shows that my GPU has memory error? What can happen with a card which has memory errors? In miner, there are NO incorrect or rejected shares?

I have an XFX RS XXX RX570 with 4G Elpida Memory.  No matter what I do, I can't get over 27.8 MH in Claymore 10.2.  I was able to get my Sapphire Nitro+ RX 570 8G Hynix Memory cards to give me 31.4 HM running at .875mV at the core and memory.  

Is this card just junk for mining or am I missing something?

Overclocking the core makes no difference between 1075 and 1210 other than power so I have it set at the slowest speed possible.
It has EDW4032BAB for Memory.  I can't seem to get it to clock higher than 1950.

This is the timing strap I am currently using at 1750 and 2000

777000000000000022AA1C00315A5B36A0550F15B68C1506004082007C041420CA8980A9020004C 01712262B612B3715

I'm willing to pay if someone can help me.

Thanks.
