hello guys excuse me for my English ... anyway .... I have a rig of 6 GPU XFX AMD RX 480 GTR 8GB and I would take them at most to undermine the greater benefit and energy savings without compromising the stability and without damage to cards ... which of these files should I install? They are compatible with my cards?
RX480-32MhOTB
RX480-30MhOTB
480LowEnergyOK
RX480Mod.zip
also with what program you can flash the custom rom?
I would have another rig 6 GPU AMD Radeon MSI RX 470 X 8GB Gaming ethos with operating system exists something for these cards?
thank you in advance

Transactions must be included in a block to be properly completed. When you send a transaction, it is broadcast to miners. Miners can then optionally include it in their next blocks. Miners will be more inclined to include your transaction if it has a higher transaction fee.

that'a another question i was going to ask as i noticed a lot of you are using W10 for mining nowadays. So W10 is recommened now for eth mining now? Are hashrates and stability issues are handled better under W10?
Didn't test thoroughly, but W10 and 16.9.1 works good on 470/80 and more than 4 cards and W7 not sometimes. hello guys excuse me for my English ... anyway ....

For Dual-Mining you should use the RX480-32MhOTB BIOS. I reached 30.5 MH and about 450 MH for SIA. And was very stabil.
But be careful you need very good cooling.
Use the latest driver 16.9.1

Anyone tried 16.9.2 yet?
I am running one PC on 16.7.3 and other one today is reinstalled fresh on 16.9.2 and it works fine. |

May times I get error on the XFX 8 gb card that OpenCL crash. On other cards it is running fine. Any ideas?
something like this on the log
11:11:45:949 129c send: {"id": 4, "method": "mining.submit", "params": ["something","752","0x00adb0780adf0226","0x6a34cdf8cc2aaf574ed1abfd7a633b869d5fb351f78a20a4f95375249fea86d5","0x6fbb6cac4d21892c667fdee33b8d674e27986cb3aa6211fb516200fb842e7245"]}
11:11:46:141 129c got 41 bytes
11:11:46:144 129c buf: {"error": null, "id": 4, "result": true}

I used 31Mh rom. That rom is for 4gb card so I the only edit I did was to change it to 8gb. Otherwise nothing was changed. Its a buffer error I guess I was not supposed to change anything.

i have tried it, running smoothly without any issue. using the 29mhs low power, i can stable at 29.5mhs with 90watt powerdraw at gpu z |

While mining XMR with modded 480s (low power version).... I find card runs cool but when mining ETH, temps runs high. Both mining using Claymore miners.
Anyone get the same scenario?
Hi, I tested on RX 470, there's 25-30w less on the wall while mining XMR. Whole system a lot more stable. The obvious difference I can see in GPU-Z is the use of the MEM controler 100% (eth with claymore) vs 25-30% (XMR with claymore). |

all of you editing timings and oc'ing memory to 2200 and higher on rx470/480 - check gpu memory error counter in hwinfo program (check sensors). I was able to stop this errors only lowering memory to 2100mhz ( I have samsung one without cooling).
It seems that this errors don't directly harm stability or performance of eth mining, but nevertheless )))

Many thanks Eliovp, great work on the BIOS mods. I currently have several 290x all with my own custom BIOS(mainly 1000/1250 and undervolted as much as possible). But just bought my first reference 4GB RX480 and thought I'd start off with one of your BIOS. Turns out the card is actually an 8GB one! Just with a 4GB sticker stuck on the box. Default BIOS gave me 24.5mh/s at 1288/2000 Your 31mhlowpower one gives me 30.6mh/s at 1191/2200. I've now started tuning in software and found the card will still do 30.6mh/s with RAM set back to 2000. Just wondered if there was a particular reason you set it to 2200? Did it provide better performance for you over 2000? Currently I've got MSI AB vcore offset set to -96mv, card has been rock solid for the last 20 hours still at 1191/2000. I think this vcore can go way down, time to do some further BIOS mods. GPUz reports about 85 GPU watts for 30.6mh/s at this setting, nice! Thanks again for already doing most of the hard work  EDIT: Found your secret sauce for the extra 2MH/s that doesn't come from memory timings.  Or clockspeeds for that matter.... Having read every page of this thread and having seen some people question a certain issue, I did wonder why no one had answered the reason why. |

What about tell everyone the magic trick ? Well, maybe I'm totally wrong. But from my own testing it appears that setting the RAM up for 4GB instead of 8GB gives an extra 2mh/s. Time for more testing.... EDIT: Think it might be something else totally..... |

Hi Walrus - can you share your 290x mod, I have a few 290 and 290x "lying" around and I was not able to find nor know how to make Stilt BIOS work on the cards. I was thinking, you mod maybe able to help get my 2 x 290 and 2 x 290x (all reference cards). Thanks in advance. |

Only voltage/power reductions, but you need to know exactly what every single card is capable of clockspeed/voltage wise. I literally have a different BIOS for each of my 9 cards. PM me, we can talk about 290x there so as we don't detract from the subject of this thread. |

What does it mean??? Not clear... Ignore me, totally duff info.... Something else was causing a 2mh/s drop. I've now got 8GB enabled and got back to 30.6mh/s. |
