That's not how GPU mining works. Mining only uses a very small amount of the slot bandwidth, which is why you can use x1 risers with a x16 PCI-E card without a noticeable loss of hash rate. As long as the motherboard has PCI-E slots, with two cards it would work.

Mazacoin is a SHA-256 coin. SHA-256 hasn't been profitable to mine with GPU's for years. You need an ASIC miner to mine SHA-256 coins. Even if you were able to get 1 GH/s you would lose money trying to mine it with GPU's after power costs.

Any motherboard with PCI-E slots v1.1 or newer would work. With PCI-E slots smaller than a x16 slot you need to use risers, preferably powered risers. Also older motherboards with PCI slots are NOT compatible with PCI-E cards or risers.

260 MH/s on what?

The AMD blockchain drivers work with the Windows 10 v1709 Fall Creator's Update, but cause the UI to become unresponsive. I switched back to using the blockchain drivers with Windows 10 v1703 and they work fine. You can also try the latest Crimson Relive v17.1x.x drivers that are compatible with the Windows 10 FCU and toggle each GPU to 'compute' mode from 'gaming' in AMD settings. The latest drivers apply the blockchain driver Dag fix when in compute mode, but I switched back to using the blockchain driver with v1703 because Afterburner won't work with the latest Crimson Relive drivers .

XFX cards are wierd to do a Bios mod on. BBT has a Bios for your card in the description of the live stream he did on those cards.

Use the Asus tweak tool to change the color to what ever tickles your fancy or floats your boat.

You only need to run the pixel patcher once after all the cards are installed. With a modded Bios on a RX 470/480 or RX 570 on Windows you need to run the pixel patcher any time the driver is updated or installed or you will have a code 43 error in the Windows Device Manager. If you install the card on another machine you will need to patch the drivers on that machine as well.

The profitability of the 1050 Ti with different algorithms is listed on whatomine. Put in how much you pay for electricity per kW in USD and it will tell you what are currently the most profitable coins based on you rigs hash rate, power cost and the coins current mining difficulty.

Right now it looks like you can expect about $1 to 1.20 per 1050 Ti per day in mining profit. Keep in mind what's listed is only an estimate based on the current figures. Your rigs real profitability is determined by when you sell in to fiat and at what price.

You can try the latest AMD Crimson Relive compute drivers. That should work with your Vega's on v1709. The reason I switched back to the blockchain drivers on v1703 is the Crimson compute drivers don't work with Afterburner. For the Dag fix on the the Crimson Relive compte drivers you need to toogle compute mode on from graphics mode for each card in AMD settings.

The 1070 Ti doesn't have an average efficiency of 4.7 sol/W. That was the maximum efficiency he was able to get on Equihash at 65% power limit with 500 sols and 110 W. The ROI timeframe with that setting is one day less than the example I used.

https://www.coinwarz.com/calculators/zcash-mining-calculator/?h=500&p=110&pc=0.10&pf=0.00&d=6251342.32482534&r=10.00056071&er=0.03002160&btcer=10178.66000000&hc=480

Better efficiency per watt is not the same as better profitability. The amount of coins you mine and most of you profitability is based on your cards hash rate. Better power efficiency is irrelevant to your profitability as long as the extra wattage spent is producing more hash and therefore coins than the extra wattage is costing you in power costs.

At $480 a 1070 Ti on Equihash has about the same ROI timeframe as a $500 1080 at 80% power limit. The 1080 mines more coins though. On other algorithms like lyrz2z the diffrence is even greater. I'd take a $500 1080 over a $480 1070 Ti any day.

One of your GPU's is probably causing the driver installation to hang. Uninstall the drivers with DDU in safe mode and click the setting to disable the Windows automatic driver installation. Install only one card on the main PCI-E x16 slot and install the AMD blockchain driver.

After the driver setup completes shutdown and connect two more cards to the motherboard. Start the computer and wait until Windows detects the cards and installs the drivers automatically. It may take a while for the cards to show up in Device Manager. Wait and confirm in the Windows Task Manger there is no running instance of the Driver Installation Module running. Once the Driver Installation Module is no longer showing in Task Manager, shutdown and repeat the process connecting two cards at a time until all the cards are shown in Device Manager.

If you have RX 470/480 or RX 570 cards You will then need to use the pixel patcher to bypass the driver signature check with a modded Bios to remove the Code 43 error in Device Manager before the cards will work. Just run the patcher, reboot and verify all the cards are shown in Device Manager with no errors.

I had the same problem when using the AMD blockchain drivers with the Windows 10 v1709 (fall creator's update). Went back to the blockchain drivers on Windows 10 v1703 and it's working.

Most likely a bad Bios mod. I suggest using the PBE v1.6.2 'one click timing patch' bundled performance timings on the original Bios. They work great for most of my cards and 90% of the time are better than just copying the lower frequency straps.

I have a Sapphire Nitro+ RX 570 4 GB card that gets 28.4 MH/s + 740 MH/s DCR dual mining with a 2020 MHz memory overclock.

Yes. These PCI-E spiltters only work with AMD cards.

Neoscrypt or Equihash coins are the best option for your cards.

ZEC was ~$64 1 year ago so with a $200 investment would could have bought ~3 ZEC.

The average difficulty was ~3M for the past 12 months, and the mining profitability has been consistent.

$200 invested in a 1060 a year ago would have netted you ~3 ZEC as well and you still have an income producing asset that is paid off.

Cloud mining contracts for alt coins are a bad investment and mostly a scam. Even at the current ZEC difficulty a $200 investment in a GTX 1060 would net you $350 after 1 year. Had you started mining ZEC 1 year ago at an average difficulty of 3M over the past year you would have mined 3 ZEC and if you HODL'd you would have earned much more.
