Don't mine without some sort of surge protection. I always see posts and people selling broken miners because a power surge broke something in them. It's a much more common issue than you might think. It's definitely a real issue.

Temps are a bit on the high side but as long as you've got aquedate ventilation in your mining space you should be fine. I'd aim to try to lower the ambient temperature of your mining space or increase airflow in the room.

Your fan speeds are pretty low which is probably the reason why they're running so hot. I'd bump the fans up to maybe 60%, tell us what temps you get then. Ideally you want to be below or around 80.

Yes, we should answer obvious questions like this that take two clicks and a pulse to answer. I would suggest actually looking into Ripple first before trying to make money from it. We're not going to hand you answers to questions like this. There's a trove of information here, don't open a new topic on a subject that has been already answered.

Whattomine usually inflates profitability a little bit. I'd probably go with the 1080 for actual earnings or peruse a different mining profitability calculator to see what you'd get on a selected algo if you're not going to mine with Nicehash. Remember you want to mine on an alt with the highest average profitability if you're mining outside of Nicehash. Don't pick a coin that spikes in profitability temporarily.

Big companies don't care about smaller players in the mining ecosystem. It's more profitable for them to ship bigger miners rather than smaller ones. There used to be a load of stickminers, but manufacturers like Bitmain and Avalon figured this out and stopped selling them.

They have websites with ads on them, what is written is posted there, then with the crypto hype still going on they get enough site hits to make a decent profit on their websites. Pretty much the usual, it's been going on for as long as I can remember.

Please don't mine on a laptop. Laptops aren't designed for being run full speed for long periods of time as they don't have the heat dissipation abilities to do so. If you want to mine, it's 1000% better to do it on a desktop.

If you really want to mine on a laptop, limit the mining program to only one or two threads, but remember it's still not a good idea to mine on a laptop (or any mobile device) at all.

The fact that these people are actually trying to make it look legit is sad. A 16nm FPGA outperforming 16nm ASICs? What a world we live in...

From what I've been able to gather through a WHOIS search, seems like the domain was registered around July 2017. Definitely not legit but I like to look into things like this.

As a general rule of thumb, if you're not buying from eBay, Amazon, a forum member with escrow, or direct from the manufacturer (or a licensed reseller like Avalon has), pretty much everything else is a scam, especially most webstores. I find it hard to believe a site created on the second of this month is legit, especially with the prices listed on the site.

I just checked their site via Google Chrome on Windows 10 and it seems fine to me. The malware alert is probably a false alarm from AdGuard and unless someone else can prove otherwise, it should be safe to use.

It's probably the new seller thing that's discouraging people from buying the miner as well as PayPal. Most people on the forums don't like to use PayPal, much less with someone with a new account. If you'd use escrow at the very minimum you'll definitely get bites. Lowering the price to maybe $4000 US may also help a bit.

Yep, well aware of this but I noticed a name or two that fell off the board or dropped heavily in hashrate. Just an observation I thought was interesting.

Some people want instant, smaller payments. Too bad for them. Our luck so far this month's in the green too. I don't actually think it was too many people leaving, though- I looked at the pool stats and it seems like one or two people with ~1PH each left.

The Crypto hype is still going harder than ever and exchanges are still being flooded with traffic. It's definitely not just you. Many exchanges have recently been forced to verify users before they can use their service, so that's at least part of the problem.

That's completely true, and Bitcoin's difficulty is rising pretty quickly with price staying pretty much stable as of right now. Difficulty doesn't grow linearly, but people buying overpriced hardware will get burned soon if the trend continues.

Seems like a good build. The cable issue is one of the reasons why I prefer to use server PSUs with BBs or soldered on cables- it's possible to make a rig with one weak psu or a picopsu and a server psu powering many GPUs as the server PSU can be fitted with all six-pin or eight connectors (or really whatever cables you want). Better value most of the time.

None.

Bitcoin mining with any non-ASIC device is pointless and has been pointed out already, so you may now be thinking about alts.

Won't work. CPU-mineable alts may yield some small profit (ex. Monero), but laptops aren't designed to be running full power 24/7. There's a good chance the CPU will overheat or run at dangerously high temps if you attempt to mine with a laptop.

If you wish to mine alts, look at the Alt Mining section for starters. For BTC mining, you should go to the Hardware section of the forum.

As long as the motherboard has PCIE slots it will take any modern GPU (99% of the time). The motherboard seems to be LGA1155 so it should be able to support PCIe. From the pictures I've seen of it and Agozyen's link, it seems to accept PCIE devices.

YES. The ASICs being produced right now will increase the difficulty of the coin like the early days of the D3. I'm not saying it'll flop like the D3, but it is possible. Early adopters always get more than the rest, though. I can see the A3 being a good miner.

One thing that must be straightened out:

This is another ASIC miner from Bitmain, designed for one algorithm only. It CANNOT be firmware flashed to mine more.

I'm wondering personally how reliable these things are and if Bitmain will stick to their promised delivery date this time. We'll probably see another difficulty skyrocket as the Blake network deals with so many miners turning on. The current network hashrate on Blake is around 620TH and one miner does almost 1T.
