Is there a reason you bought 2400 MHz DDR4 when your CPU only supports 2133MHz?

I am tired of looking around PSU with 6x or more gpu connector. There seems to be second PSU can easily be turned on using paperclip method. Is that how most miners do it?
3 month I have been doing it using a paperclip, The lack of this way is If our PSUs efficiency not so good the 12 V cable will not produce the right Voltage. So we need to create dummy load for 5V cable to make sure the PSUs produce the right Voltage. will better your using relay tool such as add2Psu. Except the Add2PSU doesn't place a load on the 5V line of the secondary PSU. It's just a 12V relay that connects the +12V power on cable and ground on the secondary PSU when it senses +12V power on the sata/molex that's connected from the primary PSU connected to the motherboard. You can create your own Add2PSU from an automotive realy. http://www.jonnyguru.com/modules.php?name=NDArticles&op=Story&ndar_id=27Dual conversion PSU's are the best because they convert the entire energy into a 12V single rail and then uses VRM to generate 5V and 3.3V. The cheaper PSU type converts using different taps in the transformer for each voltage and use the 5V line to regulate the voltage, instead of the 12V line like the dual conversion models. That causes voltage instability from not loading the 5V line. |

I have used the original Add2PSU, the copy and the ATX spliiter cable. I like the ATX splitter cables the best. Basically all you are doing is connecting the ground and +12v power on signal of the PSU's so they turn on and off together. The ATX splitter cable does it in the simplest and most direct way. The Add2PSU is just a Reed relay that joins the connections when the relay gets power from the Sata/molex connector. From my experience, the splitter cable is the most reliable method. In some cases the the Add2PSU won't turn the PSU's on/off together.

Use Claymore v11 with -allcoins 1. It's completely free with <=2GB cards, so no Dev fee to worry about. Now that ASIC's are out for DCR, you are much better off mining XVG with ~600% better profitability. You can also convert the XVG to HODL DCR if you want to.
Ahh I didn't know that, thanks! One issue though, 3 of my RX560's are 4GB cards (10 x 2GB , 3 x 4GB), is that going to cause issues as the 4GB cards will try to mine ETH right? Like it says in the v11 README: This miner is free-to-use, however, current developer fee is 1% for Ethereum-only mining mode (-mode 1) and 1.5% for dual mining mode (-mode 0), every hour the miner mines for 36 or 54 seconds for developer.
For 2GB cards (they cannot mine ETH/ETC anymore) devfee is 0%, so on 2GB cards you can mine all ETH forks without devfee, this miner is completely free in this case.
If some cards are 2GB and some >2GB, 2GB cards still mine for you during devfee time, only cards that have more than 2GB memory will be used for devfee mining. Miner displays appropriate messages during startup. The Dev fee will only be mined with the cards that are >2GB. |

Paying over double MSRP just to get ~30 MH/s doesn't sound very smart to me. Especially when the next gen cards are about to be released in less than 2 months for Nvidia and 6 months for AMD. Once the new cards come out, you would be lucky to get $200 for a used RX 580. The HD 7850 can easily get 17-18 MH/s on Ethash (<2GB Dag). Six cards will give you 108+ MH/s. You can actually get 19.5 MH/s at -ethi 4 in Claymore, but the cards will run hot. They also get 500 H/s+ on Cryptonite and 195 H/s Equihash each. https://bitcointalk.org/index.php?topic=2520971.msg25750026#msg25750026There are also newer cards you can use that can give you a much better ROI than paying $600 for a RX 580. https://www.youtube.com/watch?v=Pb6B_qpr180 |

If you are on Windows 10 v1709 you should use the latest AMD Adrenaline drivers. I'm running the latest v18.2.2 driver with 13 cards and 7 card rigs. I set the overlcocks/undervolt fan speeds with Claymore v11 without problems and it's very stable.

Well at $600 for a RX 580 it may take you a year of 24/7 mining to even get your money back. If you ever want to sell the card to upgrade in the future, you will take a huge loss. If I were that desperate to start mining, I would rather buy 6-7 used HD 7850 2GB on eBay for ~$500-600. That will give you 108-125 MH/s on Ethash coins with a Dag <2GB like UBQ, EXP, PIRL, etc and also ~1170-1365 H/s Equihash and ~3000-3500 H/s on Cryptonight. Much better ROI and you can also trade those coins for ETH if you want.

If you are seriously contemplanting buying an RX 580 for $600, you're already making a mistake. If you can't get cards for closer to their MRSP, then I would just wait.

As a disruptive technology, the Cryptoverse is a fast growing and quickly changing space. Mining is like working for a startup, with all the uncertainty and benefits that brings rather than the predictability and structure of a corporate job.

It could be a bad connection between the x1 PCI-E connector from the riser and the slot or the USB cable. Make sure the connectors are pushed in well or try replacing them. Normally that would cause the GPU not to show up though.

Adjusting the power limit up can also help. The most common reason for a GPU hang is too little power or too much overclock. What I do when a GPU hangs, in order until it's stable is:
1/. Increase the core/vram voltage by 50mv.
2/. Increase the power limit by 5%
3/. Decrease the core and/or memory clock by 50 MHz
The first two may increase the GPU hash rate, power consumption and heat. The last will decrease the hash rate.

Not sure if ive just got bad luck but Sapphire has been a nightmare to deal with. First their itx model fan died with 6 months of mining use. then the cs sends me a replacement card that has the SAME problem. Now im waiting for a replacement gpu to ship from Hong Kong (its been 8 weeks already) wtf. Here's how it looks and sounds. NEVER buying sapphire again. https://www.dropbox.com/s/gjl60zoknasdw8b/IMG_9230.MOV?dl=0Its MSI, evga or asus for me. TAT for Asus 1-2 weeks tops for rma. That's why I also like buying cards that run cool and never buy single fan cards. Cheaper cards always skimp on cooling and the better the passive cooling, the lower you need to keep the fan speed which makes them last much longer than fans always running the 80%+. |

With the current GPU mining runnup already outlasting all the previous ones by far, GPU manufacturerer's should realize nobody wants to RMA a GPU for fans, which is usually the first thing that goes bad. Sapphire and XFX have stepped up their game with one screw and snap-on modular fans. I love the Sapphire dual ball bearing X-Fans on the RX series. One screw to take off the fan for maintenance and cleaning and no wires to run or deal with. Replacements are $12.50 each including shipping from Sapphire and they are super easy to replace.  |

Biggest rig is only around 200 Mhash - that's well within standard GPU mining rig territory. I'm more worried that Antpool added ETH and ETC options at some point - *USUALLY* Bitmain doesn't add coins unless they are working on an ASIC for that algorithm, though ETH in particular is "big enough" they might have just added it for the pool fee income. Going by this thread, Antpool has had an ETH pool since at least May 2016. https://bitcointalk.org/index.php?topic=1490172.0 |

Yep the new scam is fork a masternode coin with a premine, run a pre-sale of the masternodes, dump the premine the second it gets listed on a shit exchange, then rinse and repeat. https://youtu.be/gapEN1Jap1M?t=273 |
