Ok so I did the my first successful 1500 strapping on my two rx 470 4g. One is at 23 mh/s and the other 22. Up from around 19.5. Is that good? What can I do next for more performance!
1150 MHz core clock, 2000 - 2100 MHz memory clock should get you to ~29 MH/s stable with a good timing strap bios mod. Also run HWinfo 'sensors only' to check for memory errors and reduce the memory clock by 25-50 MHz until there are no errors. Im up to 26 mh/ each now. at 1150 1950 -70 voltage. Past 1950 is black screen. Not bad for 470 4g It should be higher. Try increasing the -ethi to 8. My eight card mixed RX 570/570 4GB/8GB rig is getting 28.5 to almost 30 MH/s dual mining UBQ.  If you are on Windows mining ETH make sure you have the blockchain drivers with the epoch Dag fix patch. you got that 28.5-30 mh/s owing to low epoch of Ubiq I believe.  try to mine etc at epoch 144 and you will see. ETH Dag file has virtually no difference compared to UBQ using the beta blockchain drivers. Less than 1 MH/s average speed difference over 8 cards.  |

Swapped Raiser to see if this is a raiser issue. It's not. Same card still works with different razor.
How can it be that windows will detect all cards, but claymore won't fire them all?
Check Device Manager in Windows to see if the are any GPU's with errors. If there is a Code 43 error, the cards have a Bios mod and you need to run the pixel patcher to bypass the signature check. https://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-PatcherIt may be a bad Bios mod causing the card to crash. You can try flashing the original Bios using Atiwinflash. Check with GPU-Z if they are Sapphire Pulse RX 580 4 GB or 8 GB cards and what memory type they have. I have a Sapphire Pulse RX 580 4GB card with Hynix memory and I uploaded the original Bios below. Don't try it if it's an 8GB card or any card other than a Sapphire Pulse RX 580 4GB with Hynix memory or if it shows a different memory brand in GPU-Z. Backup the Bios that's on the card first using Atiflash before flashing the Bios. shasum d87b2cd077331941476bd93d05bc260e62371b4b Sapphire_Pulse_RX_580_4GB_Hynix_Original_Bios.zip

Can't thank you enough for your help. Just to confirm - once I click the "check" button on Afterburner - voltage has been applied? Or do I need to do something else? (very bad UI i think) https://imgur.com/YXVsWavEDIT: only the 2 will work (circled in blue): https://imgur.com/V4qj7pTYes, once the check is grayed out it means the settings are applied. Try running the miner again. If you are using a config file, make sure there are no -cclock or -mclock parameters listed in it. |

Thank you so much. Reduced via your link (beta msi afterburner) trying now.... EDIT: according to this (just noticed - noob to this): the GUPs are not even active? Is this correct? Might not be a memory issue then? https://imgur.com/sMuSEfzEDIT 2: Also - tried to run TRIXX (can't remember why though - got it from some link at google): and got this error (not sure if it's relevant but thought i will attache) https://imgur.com/ba4L59Xhttps://imgur.com/PctPBSlThe cards showing zero hash means they have crashed. Restart the rig and try again after setting the core clock to 1150 MHz and the memory clock to 1950 MHz in Afterburner. If the cards are hashing, check for memory errors in HWinfo. If there are no errors and it's stable, you can try increasing the memory clock by 25 MHz to see if it's stable. It could also be a bad riser. Double check the riser is connected all the way and switch them around if you're still having the error. The OpenCL error in GPU-Z means you don't have the AMD APP-SDK installed. Just install the latest OpenCL runtime libraries from the latest version. http://developer.amd.com/amd-accelerated-parallel-processing-app-sdk |

That error just means the card is overclocked too much. Try lowering the memory overclock by 25-50 MHz and see if it helps. Also run HWinfo 'sensors only' to check for memory errors and lower the memory clock until the are none.

I dont understand the bios modding. What am I to be changing on my Polaris cards I am only get roughly 20mh/s out of them on ETH.
When i load the bios following instructions, they say change timing, the timings are all kinds of crazy hex numbers.
I also get an error about my bois being too small
You cannot use GPU-Z to save the BIOS as it only saves half of modern bioses. You must use ati flash to save the bios. You are copying the memory straps from either 1500 (hynix, micron and elpida) or 1750 (samsung) and pasting it to all memory straps higher than it, such as 1650, 1700, etc up to 2000 or higher. This makes the memory run with tighter memory settings so hashes more. But it can also make the card unstable and/or crash. How do I tell memory brand... also I am using ATI flash to pull them. They appear to already read as 2000 as thier default memory speed? When you start GPU-Z, it reports the memory brand. Also use the following article for BIOS flashing as it tells you the correct Polaris BIOS editor version to use in order to get rid of the craxy hex numbers you're seeing: http://1stminingrig.com/sapphire-nitro-rx-470-8gb-oc-bios-flash-mod-tutorial-hynix-samsung/Okay all m y cards are hynix so I can OC them a bit? My screen for timing looks nothing like his.  You are using outdated version of PBE. Find a good step by step instruction with the links to the 1.4.1 version The most current version of PBE is v1.6. It now includes 'one click' bundled performance timings. Very easy to use. Just save your original Bios using Atiwinflash and open it in PBE. The 'one click' option automatically applies the bundled performance timings and then save the bBios and flash it using Atiwinflash. https://bitcointalk.org/index.php?topic=1433925.msg21518785#msg21518785This version applies performance timings to the 2000 strap by default. Any way to get it to apply performance timings to a lower strap? The timing is applied according to what your cards memory type is. If you want you could copy it to the other timings manually by clicking on the strap you want to change and using the box on the bottom. I found it wasn't necessary and the cards are more stable than when I was just copying the 1500 Mhz strap to the higher frequencies. |

I get error 43 after flashing straps with atiwinflash. Is it true that I need pixel patcher to solve the bios signature check?
For most cards yes. Some RX 580's I have don't need the pixel patcher. |

The latest version of Polaris Bios Editor v1.6 from jaschaknack makes it simple to apply the right performance timings for your card. With the 'One click timing patch' option it will apply the bundled performance strap to the correct timings. I tried it with several brands of RX 570/580with Hynix, Elpidia and Samsung memory and they all now get 29 M/s+ stable. Much better than randomly copying timings from the diffrent straps. Some cards like the Sapphire Nitro+ have two diffrent sets of straps from diffrent brands of memory and PBE will corretly detect and apply the right strap to the right timing. Great update! https://github.com/jaschaknack/PolarisBiosEditorGoing to try this out now Remember to save the Bios after it's patched |

This is a good 1750 MHz strap for Sapphire Nitro+ RX580 8GB cards with Hynix memory from BuriedOne on Youtube. 777000000000000022AA1C00B56A6D46C0551017BE8E060C006AE6000C081420EA8900AB030000001B162C31C0313F17 I copied it over the 2:1750, 2:2000 and 2:2250 timings on a Sapphire Nitro+ RX 580 8GB Special Edition (blue faceplate) and get ~29.25 MH/s ETH + 935 MH/s DCR with a core clock 1120 MHz, memory clock 2200 MHz, -96 mV undervolt and power limit -15% in Afterburner. Runs stable with no memory errors. Turns out that Hynix strap from BuriedOne is the same one bundled with the new version 1.6 of PBE. LOL.

Good for them. The less people that get scammed with ICO's, the better off Crypto will be. When anyone that produces nothing more than a whitepaper with a dream and a wallet can get 100M, it's not going to end well for those investing. |

IMO, the Sapphire would be the best choice since it says it has Samsung memory. The Sapphire was the same mining edition card sold on Newegg. Never heard of the other two.

Okay all m y cards are hynix so I can OC them a bit? My screen for timing looks nothing like his.
Seems wrong version of PBE, you need to find one which display the timings properly... did you try the one in the article I've sent earlier? ...and always 'Run As admin'.... Yea Ia m using Polaris Bios editor 1.4 and atiwinflash Use the latest v1.6. You definitely don't need to run PBE as an administrator. Atiwinflash does. https://github.com/jaschaknack/PolarisBiosEditor |
