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.
Sata to molex or straight molex to molex from the PSU?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.
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.Hopefully this will lighten the demand for GPUs.

I looked into it a bit. I doesn't exactly scream SCAM like some of the others that have come and gone but still looks pretty shady to me. Money back if they miss delivery deadline but the deadline advertised has already passed? Also no deposit money back. They don't even mention if it's an ASIC. I suspect if it's real they're using some sort of FPGA setup given the hashrates and power usage isn't that much better than a proper 480 mining rig. It looks like they're pulling an Alpha litecoin scam. String people along for the deposit money and never actually deliver a product.It shows the pre-order price is $399 (down), with the "rest payment" of $1,800 USD.

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.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
It depends on the card, but I'm not 100% sure they'll ever be able to fix that with drivers, at least not with the reference cards. Undervolting is obviously your friend for any cards that have to share a SATA cable.Brave, stupid, often the same thing.
I was under the impression that was fixed in the driver updates?
These are what most of the risers come with. I think sata is on 12v rail vs 3.3 or 5v for molex and that is the reason. Could be wrong thoughI'm pretty sure it's the other way around no?

Does the AMD control panel show four cards?Guys im having some problems getting windows 10 detecting my 4 asus 470it 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)
https://www.mediafire.com/?1z0bm9n3uvajrxe
https://www.mediafire.com/?22evbb4cmjle4o8
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
device manager only sees 3 cards, every fan/led is on buy the mobo wont detect the 4th card, any suggestion maybe a bad riser?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?
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.Ok mining with 3 cards, cant get my mobo detect the 4th card, which app do you recommend to modify voltage without bios mod?
will do that tomorrow, thanks for the suggestionTry uninstalling your drivers with DDU and reinstalling the latest driver version.

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.
I would assume that if it's just a static algorithm, then ASIC's will eventually just take over. GDDR5/X is pretty cheap.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?
The DAG isn't a static algorithm, it'll be pointless to buy one of these units even if they're magically somehow real (doubtful). There's more money in mining then selling hardware at the moment so any company who had the R&D to build one would be mining themselves (just like Butterflylabs and many other companies followed suit) instead of immediatley selling.I would assume that if it's just a static algorithm, then ASIC's will eventually just take over.
