I'm running a rig with 4 GPUs, one of which is a Sapphire 470 aftermarket. All 4 cards are connected to powered risers with molex cables. It's rock solid stable.you should be fine with just the 3 SATA power cables and double up one of them. Use wattman in radeon settings driver to undervolt. I've heard not to use direct molex on the riser cards as they dont deliver enough voltage
I'd be careful about this. A number of similar "products" have appeared over the last several months that all turned out to be scams.https://www.eastshore.xyz/shop/ethereum-miner-geass-198mh-asic-miner-for-ether-mining/
Hopefully this will lighten the demand for GPUs.

It shows the pre-order price is $399 (down), with the "rest payment" of $1,800 USD. Alternatively, once Full Payment is selected in the toggle option menu, the full price becomes $2,199 USD. The RX 480s can be resold for a decent amount of $ in 2017 or during any time should ethereum fail during the next 12 months. If mining fails, that $2,200 USD specialized part is worth close to $0.

Brave, stupid, often the same thing.
I was under the impression that was fixed in the driver updates?
I'm pretty sure it's the other way around no? If possible, you want to be using Molex->Molex direct from PSU into the risers, rather than SATA -> Molex power adapters like these.
Guys im having some problems getting windows 10 detecting my 4 asus 470 it only detects 3 no matter what i do
Besides that im having some problems too with the hashrate, 1 of the 3 cards its getting really low hashrate, any suggestion?
I hadnt touched anything on any cards (bios, voltages or anything)
Im using lastest version of claymore (7.0)

Im running this on a Gigabyte AM3+ AMD 970 SATA 6Gbps USB 3.0 ATX AM3+ Socket DDR3 1600 + AMD FX 4-Core Black Edition FX-4300 with EVGA 1000GQ, 80+ GOLD 1000W, Semi Modular, EVGA ECO Mode, 5 Year Warranty, Power Supply 210-GQ-1000-V1
I really appreciate it any suggestion
Does the AMD control panel show four cards?
Does the Device Manager show four cards?
Can you try mining in ETH only mode and see what happens to your hashrate?
Ok mining with 3 cards, cant get my mobo detect the 4th card, which app do you recommend to modify voltage without bios mod?
Try uninstalling your drivers with DDU and reinstalling the latest driver version. If that doesn't work try musical chairs with the PCI extenders, sometimes just swapping cards help them show up. Check your BIOS and make sure nothing else is taking up PCIe resources. Check device manager and see how many cards are listed under displays. If you have one card listed with a yellow exclamation mark check the error code (probably IRQ conflict). I have one board that I had to change a setting (sorry the name I forget), basically disable the on board PCIe mSATA port for all five cards to show up.
Just some ideas, good luck.
Low hashrates are usually caused by overly aggressive memory speed settings. Supposedly AMD added some advanced logic that counts the number of memory related errors over a set period of time, if the number of errors exceeds a certain threshold the card will throttle your memory down automatically instead of just crashing. Try backing off on your memory speeds a tad and see if your hash rates stabilize. Alternatively increased the voltage to your memory and up the fan speeds to compensate for increased heat.
Ethereum's algorithm needs a ton of memory bandwidth specifically to minimize the impact of ASIC miners, if it is real, it probably has a very interesting/unique memory setup.
To fellow Canadians;
I've been following this tread for a while and I've accumulated a few hundred ETH and was thinking of cashing some to cover the cost of the hardware. Has anyone investigated how this all works with CRA?
Do we need a business to be able to claim electricity and stuff?
I would assume that if it's just a static algorithm, then ASIC's will eventually just take over. GDDR5/X is pretty cheap.
