The RX 480 should still be under warranty. You will likely have to send it in to get the fans replaced under warranty.

Can anyone confirm that DAG slowdown will also affect 5xx series?
As it it right now, the Claymore miner epoch benchmarks show a rather significant ~10% drop after epoch 150 for the Polaris cards and progressively increasing after that. There are conflicting reports as to whether the issue is with the Claymore miner and if other miners, like SGminer are affected. Apparently AMD is also aware of the issue and are talking with Claymore about it. |

I don't think you can dual mine ZEC like you can with ETH. What I do is run Claymore with the AMD cards dual mining ETH + DCR and mine ZEC with the Nvidia and a 2GB card.

Only what BBT said in the comments of his video. Yes, it works fine with SGMiner in Linux, Claymore working with AMD directly to address. Bottom line, SGMiner does not experience the issue. He also said he was going to do a live stream last night once he was able to confirm whether what he was told about it only affecting Claymore's miner was true, but nothing yet showing any confirmation. As I said, BBT is in over his head. Among other dumb statements in the video, he claimed the issue is because Claymore uses an asm kernel. There's also nothing special about exchanging emails with AMD devs. Matt, Tom, Alexander, and others are reasonably responsive. What would be impressive is if they can tolerate a mediocre Russian programmer with an ego bigger than his mouth. Well BBT said AMD claimed to their knowledge, only Claymore was affected. He's also not backing down from the comment he posted earlier. Michael Carter4 hours ago

SGMiner (Linux) using OpenCL 2.0 does not have the same issue after EPOCH 150+.[/quote] |

AngryChicken on Youtube got 11 cards 325 MH/s on a Asus Prime Z270-A using two of the expansion risers and two M.2 to PCI-E converters. He says he could only get two of the three 1x slots to work at a time, using three would cause a crash. From what i've heard they only work with AMD cards. https://www.youtube.com/watch?v=UPGxVUaSdvc |

False, can confirm it's affected. Strange since the guy tested it out and replied "Yes, it works fine with SGMiner in Linux, Claymore working with AMD directly to address. Bottom line, SGMiner does not experience the issue." Also, Claymore is working with AMD directly to address? That fool is more full of shit than a sewer. Claymore has confirmed he's working with AMD developers on the epoch benchmark issue. https://bitcointalk.org/index.php?topic=1433925.msg19798453#msg19798453 |

You can only get up to four AMD cards on Windows 7. You need to upgrade to Windows 10. There is supposedly a patch workaround to get more cards working with Windows 7, but I couldn't get it to work with the latest AMD drivers. https://bitcointalk.org/index.php?topic=712228.0All of my 4+ card AMD rigs are working on Windows 7 with no problem for more than 3 years. Try running the mod with administrator priviledges, its pretty weird that it wont work for you. I did and it won't even boot in to Windows. Are you using the latest driver? I've used 17.4.x, 15.12 (Non RX cards), 16.7.3 and are all working fine for me. You dont need latest drivers as they may still be buggy. I was able to get five card in Windows 7 since I also have a 1080 and the Nvidia driver installed. When I run the patcher it warns that there is more than one version installed and quits. If I force the patch it won't even boot in to Windows. I switched to Windows 10 and all six RX 480/580/570 and 1080 cards work. |

What OS? You can oly get up to four GPU's in Windows 7.

The liquid cooled AMD R9 295 X2 can do ~65 - 70 MH/s each but use 300W. If you can pick up used cards and have good electric rates, they are another option to overpriced Nvidia 1080Ti's. Problem is they are going for 3x what they were going for used two months ago. https://youtu.be/TM8Pj_uLqxA?t=5304 |

Obviously you will get the most hash out of four Nvidia 1080Ti, but that it also at least $2800+ just in GPU's. A better hash/cost, lower power requirement/usage and quicker ROI would be to go with four 1070's if you can get them for $450 or less each.

I don't have first hand experience with EVGA warranty service, but have seen they are good at standing behind their products. My opinion on extended warranties in general is that they are a big profit center for companies that offer them and therefore not a good deal from a consumer standpoint. I think with VGA's this even more so, given will you even want the card after the initial 3 year warranty expires?
You have a point, but equally if they did break, you could get it replaced with new then flog it.... That could be one benefit, if you're still using the card after three years. Also the fans will almost certainly go out before anything else and way before the warranty ends if using it 24/7 for mining. To maximize the return it would be better to sell it off before then. |

You can't use your PCI slot for mining. It has lower voltage than PCI-e. You can use M.2 slot if available with adapter to PCI-e.
Or a PCI-E multiplier card, only if the motherboard supports it. Also AFAIK the M.2 and spliiter cards only work with AMD cards as well. |
