With POS coins you are staking coins i.e. holding coins in a full node client wallet to accumulate enough stake to mine a block and earn a reward based on the POS annual percentage rate for that coin. Typically with POS you can hold any number of coins and still be eligible to stake. The more coins you have and the longer you have them staking, the quicker you will be able to earn enough stake weight (similar to hash power in POW mining) to mine a block and earn a POS payment. Your client node doesn't need to be online to earn stake, but it must be online to be able to mine a block to earn a reward. With some POS coins you need to stake the coins held in your wallet within a set timeframe or you will lose the stake for the portion of the time period that is past the cutoff.

The Asus B250 mining expert motherboard is gimped by design. You are REQUIRED to buy and use overpriced and unavailable Nvidia P106 mining cards with more than 13 GPU's.

That's because there is no official GUI wallet for ZEC. It's a 3rd party wrapper that sits on top of the Zcash command line client.

Awesome update. On 3.0 I'm getting 1080-1090 Sol/s with a GTX 1080 and 1070 @ ~300 W! The high CPU usage is now gone with ~30% usage on a G1840. Thank you!

The 11.0 update finally works about the same as v9.7 with my HD 7850. With -h 515 -dmem 0, I get ~ 512 H/s. Fan speeds and temps working with the blockchain drivers. Thank you for the update, I can move off of v9.7 that was giving me problems with the devfee, so I had it set to nofee 1.

You need to use the pixel patcher with RX 470/480 and 570's. For the PBE 'one click timing patch' Bios mod I get the best results with Polaris Bios Editor v1.6.2. It automatically detects each memory type and adjusts the 1750 MHz and up straps with the bundled performance straps. PBE 1.6.1 adjusts from the 2000 MHz and up straps. PBE v1.6.3 and up adjusts the straps from 1500 MHz and up, but the 1750 MHz straps are more stable.

You should only use the PBE 'one click timing patch' Bios mod with the original Bios from the card.

They all have about the same performance. I like Sapphire Nitro+ because they are easy to Bios mod and have good cooling. Powercolor Red Dragon RX 570 4GB is also a good card. Asus is good, I don't like Gigabyte cards.

If you want to mine Cryptonight, see if you can get RX 570 4GB cards. That will give you the best cost/hash with a limited budget, around 850-900 H/s each. You don't need an i3 for a mining rig, a Pentium like the G4400 is enough. You also need 4GB of RAM and PCI-E risers.

You can probably can, but IMO there is no good reason for doing that since the P106 cards are overpriced to begin with and you are also making the build configuration more complicated by mixing different drivers and cards.

The P106 mining cards are overpriced for what they are, a 1060 with limited to no resale value. I would reconsider and go with better options, like the ASRock H110 Pro BTC+ and run 13 card rigs.

Absolutley. I run a 13 card build on the ASRock h110 Pro BTC+ with three PSU's. I use the primary 1600 W PSU for the motherboard, all the risers and the VGA power for 3 cards. The other two are just for the VGA power on the rest of the cards. To join all three I use a triple ATX splitter cable to sync all three to come on and off together.

You NEED to use Nvidia P106 mining cards for more than 13 GPU's on the Asus B250 mining expert. Nvidia/AMD, Windows/Linux it doesn't matter, the Asus B250 REQUIRES the Nvidia P106 mining cards NOT 1060 for more than 13 cards. Watch this video BBT goes over his B250 mining expert 19 card setup why you need to use the P106 mining cards with more than 13 cards.

Asus was supposedly going to release an update to bypass the requirement to be able to use 19 regular cards, but I wouldn't hold my breath.

In a recent Ethereum developer meeting it was discussed preparation for the hybrid POW/POS implementation is at a point where it could be released in the next hard fork, Constantinople, which should be early next year.

The final POS implementation is still being researched and the details will certainly change as development progresses, but I wouldn't be surprised to see the move to a hybrid implementation sooner than people think.

With POS coins you are staking coins i.e. holding coins in a full node client wallet to accumulate enough stake to mine a block and earn a reward based on the POS annual percentage rate for that coin. Typically with POS you can hold any number of coins and still be eligible to stake. The more coins you have and the longer you have them staking, the quicker you will be able to earn enough stake to mine a block and earn a POS payment. Your client node doesn't need to be online to earn stake, but it must be online to be able to mine a block to earn a reward.

Ethereum will be switching to a hybrid POS/POW system with the Constantinople hard fork expected early next year and it's expected to switch to fully POS in the Metropolis release by the end of next year. That means you won't be able to mine ETH with GPU's after that and instead you will need to hold a number of coins to stake and generate new ETH as interest on the coins you hold.

For a 19 card build, the Asus B250 mining expert REQUIRES using at least six Nvidia P106 mining cards if you want to run more than 13 cards. You don't need a 500 GB SSD for a mining rig and it's just a waste of money. A 128 GB is plenty if you want to run Windows or a 32GB USB 3.0 flash drive is plenty for running a Linux based mining distro like ethOS or smOS.

RX 560's are a good inexpensive low power option for mining ETH. They use about 60 W and if you can get 17 MH/s, that is a very good cost/hash ratio. Increased availability on RX 570/580 from the Vega launch has lowered the demand for lower performance cards like the 560 for mining ETH. I would say you could definitely mine profitably with the 4GB cards before the ETH switch to fully POS sometime next year and can still mine other ETH based clones.

If you want to mine ETH to cash out in to fiat and are in the US, you can use a GDAX (owned by Coinbase) ETH wallet address, trade the ETH to BTC, transfer the BTC to Coinbase for free and then sell the BTC for USD and transfer it to your bank account for a fee or get a Shift debit Visa card connected to your Coinbase wallet to spend the BTC with no fees.

The minimum deposit amount is 0.01 ETH and GDAX only charges 0.30% fee on the taker of the trade. Transfers from a GDAX wallet to a Coinbase wallet are free and instant. Cash back transactions with the Shift card and purchases are also free or you can do an ATM cash withdrawl for a $2 fee + the ATM fee.

Exactly. A $2000 investment in ETH at $300 in June would have gained about 240% as of now and be worth ~$4800. A $2000 investment in a 6 card RX 570 4GB mining rig back in June would have netted about 0.7 ETH per month for ~$45 in power costs a month. Today that ETH is worth ~$3000 and you still have the mining rig producing more ETH for the cost of your power regardless of what happens to the price of ETH.

Not sure, it looks like the 009 risers have gold plated USB connectors, dual LED's and the wider PCB. In the comparison there is no mention of the lower power consumption like the 008C

They also have a ver. 008S multi 4/15/6 pin riser, but no mention of the lower power consumption.

The RX 570/580 are currently the best cards for mining ETH by far.

Vega 56/64: 44-46 MH/s $500-$700 each = $11.3-$15 per MH/s on ETH
RX 570/580: 28-31 MH/s $250-$300 each = $8.9-$10 per MH/s on ETH

You would be better off mining XMR with the Vega's instead of ETH and then converting to ETH. Even then the RX 570/580's get about half the hash rate for about half the cost of the Vega, so hash/$ is about the same.
