Yeah, the voltages should be less than 900mV with these core clocks. The main problem would be Anorak's bios, it's not very good, he just copy and paste straps from 1500 and up. You can do it by yourself with stock bios it's better, but still not very good.
You are right i guess, because it's not stable anymore. Currently i change core voltage to 66, core clock to 1225 and memory clock to 2000 and want to see this for couple hours. If this configuration failed i want to restore to it's original rom and start all over again in strapping 1750. Do you have any specific rom for my cards? Regards. |

Core voltage 66? What? No, I can mod your stock rom. I always do. |

Sorry, typo it's for -60  Currently i'm testing this configuration, hope this would be nice. Thanks.  |

Hi Matt, I have change into 1100 few minutes a go, let's see for the next 12 hours. I hope it would be ok. Thank You. |

Hi all...... Im losing my SH*T over my setup, and im hoping someone here can give me a little advice/assistance..? Any real change to my overall hashrate brought about by specific advice (or bios) will win some love, and a little pocket money  Im running linux (Ethos) with all Powercolor 570 Red Devil, 30 are hynix, 90 are Elpida my cores are set at 1240-1280 my mem speeds are anywhere from 1800-21701500 strapped up to 2000, 1: and 2:, (in polaris), no undervolt, running claymore, mining just ETH (at the moment) 6 card rig hashing at around 160mhs draws 930w at the wall... http://jays20.ethosdistro.com/(Fans are temporarily on 100% with temps between 55-80, until my aircon guy gets off his arse and charges it up for me!!) (the room is at around 35-40 at head height, 3m high room with cool air blown in at ground level and hot extracted from the ceiling above the rigs) Have a look, laugh at me a little, then let me know those sweet sweet little titbits of information..!  Thanks, Jay |

@Mattthev are you familiar with doing offsets via bios? I only have about 60 cards right now and only a couple batches of 5 that are the same model... so the tool that is out there for 1.5btc isn't worth it for me.

Why not just a simple google search with: sapphire rx 580 nitro+ 4gb elpida bios mod. You might be able to find something... C/P 1500 strap up to 2000 are not optimal at all but should gives you some good gains. A perfectly edited vbios have a price cause it have takes hours from developer to test and improve, so almost no already edit vbios you could get for free are perfectly tweaked, but for free you can't complain. Tonnes of basic tutorials are available on YouTube to learn how to mod your vbios. Have only 1 Amd with elpida and using the simple C/P trick have got some decent results, take a look on page 2 of this thread, you might find something good for Elpida mem, but haven't test it yet. If I see an improvement using this strap, might be able to assist you a lil more with it. |

Ask Wolf0 here, he would do it better than me. got 31mh/s. thank you. Very good, I suppose it's not one of Anorak's  What are your clocks and voltages? |

Mattthev & Wolf0, do you know if AMD's RX 550 vbios can be modded too? They offer very decent hash/dollar in XMR. Was wondering if they could benefit from tighter mem timings accordingly...

Probably yes, but not in PBE or SRB. You need at least RX 460/560 and you can unlock shaders in SRB for RX 460. |

Added guide for SBR Polaris!
I will also add guide for Afterburner overclocking and undervolting.
