I have the same issue with one of my Powercolor RX 570. I ussually means either too much overclock or too much undervolt that is causing that card to crash. Your clocks are not too high, so try setting the core voltage to the default and the power limit to -10%. It could also be a bad riser.

No wonder. The Asus Z270-A has no supplemental PCI-E power connectors. So all the power for the x16 PCI-E slots (up to 75W each) was coming from the 24-pin. No way you should use cards connected to the PCI-E x16 slot or unpowered risers to for dual mining with multiple cards. Get some powered risers.

Tell your Pops he's right, but the risk is directly proportional to the coefficient of the organic matter operating it.

How were the PSU's connected together? How were the risers and cards connected to the PSU's? What kind of risers?

A good first step may be to post your rig configuration so people can know what you have connected to the board and PSU. My crystal ball broke yesterday.

You are a scammer and no, you didn't do the work. The developer did the work which you want to take credit for by compiling their work and distributing the executable, breaking the GPL license and screwing the developer out of his voluntary fee.

Windows 7 only supports up to 4 cards of the same brand (AMD or Nvidia). Update to Windows 10 for free while you can. The assitive technologies loophole ends on Dec. 31. https://www.cnet.com/how-to/microsoft-windows-10-free-upgrade-offer-assistive-features/You also need to increase the clock speeds. Uncheck the option to synchronize settings across similar graphics cards in the Afterburner settings. Set the core clock to 1150 MHz on all the cards, 2000 MHz for the memory clock on the RX 570 and 2100 Mhz for the memory clock on the RX 480/580. You can also undervolt the cards -100 mv and set the power limit to -15%. |

Problably because they think it's just for PCI-E auxillary power, which on other motherboards like the ASRock H81 and H110, isn't required unless you are not using powered risers. The Asus B250 has 24-pins for up to three PSU's directly on the board though, so it's a good idea to plug the connecors in so that the PSU's share a common ground together.

As long as you use a good ATX PSU like a EVGA G2/P2 and cards that have a good cooling, you won't have a problem. The most noise you will have is if you add a box fan to keep air circulation around the cards. Not really necessary for just 4 cards in an open air rig though.

As long as the motherboard has PCI-E v1.1 slots or higher you should be able to use the cards without any problems.

The Dag file size is not something you need to worry about. Currently the ETH Dag file is 2.2 GB and it won't hit 4 GB until at least the fall 2019. By then ETH is expected to have long moved to POS only, so mainly the issue will be with older ETH clones like ETC. There are also lots of newer ETH clones that you can mine currently with even 2 GB cards like UBQ, EXP and MUSIC.
The only real consideration is 8GB cards will hold their value better with gamers, so if the price difference is ~$20 I would say go with 8GB cards, which also have faster memory compared to 4GB cards and dual mining is slightly better.

Download the latest driver from the AMD website if you're on Windows 10 v1709 and do a clean install after running DDU in safe mode to remove the old drivers. Be sure to enable the option in DDU to disable the Windows automatic driver installation.

Power supplies lose a lot of their rated power and become less efficient over time. With a power supply that old it's hard to say but RX 460's are low power cards. You are probably looking at 150 W max for both cards, so I would say it's OK to try.

It depends on the pools payout structure. The most common types are PROP and PPLNS. On a PROP pool, when the pool finds a block, the block reward is distributed proportionally between all the miners that contributed valid shares towards that block according to the amount of shares they contributed minus the pool fees and then all the contributed shares are reset for each new block the pool finds. PPLNS pools are similar, but instead of just looking at the total shares contributed towards the current round (block) by each miner, it only looks back at a set number of shares in a window (N), regardless of the block boundaries and distributes the reward proportionally based on the the total shares contributed by each miner during that window. Typically the payout window (N) is large enough that it will cover at least a few blocks.
