Got mine running. I am impressed with the noise, VERY acceptable. It's the sound of a small level of a small desk fan. Now I just need to see if the heat is acceptable.
After 12m, miner is reporting avg hash rate of 8565 Gh. Nicehash is reporting an accepted rate of 10.2Th (!) reporting a payout of $6.3/day.
After 35m, miner reporting 8691 Gh, Nicehash reporting 9.5 but bouncing around.

Well what is the guess for BTC difficulty for the next year it takes to ROI...is it gonna be 'flat' due the the halving or nuts as usual..if it is flat you could do ok with a 1 year
ROI on this beast
comments anyone on above? Is that the plan for those getting an R4 (that and a hopeful price pump of BTC)....
id expect to see at least a 50% increase in hashrate over the span of the year, probably closer to 70-80% (assuming fairly stable price and no major changes in hardware prices). thats about 2-2.5% increase per difficulty period
considering the miner makes ~$5/day, minus ~$2/day if you pay ~$0.08usd/kwh, you're looking at an ROI of more than 18 months probably. if power is "free", more like 10-12 months.

a video would be nice to see the R4 in action !
TIA for sharing.

please pull gear out into the open and give a close shot of all 14 plugs and wires and connections to the psu.
also how loud is it?
this would be a decent psu if it is quiet and can feed 2000 watts
Just received the first batch of APW5 PSUs and R4s. I was a little uncertain about the actual number of 6-pin PCI-e connectors it came with due to some of the images showing only 7 connectors total. I'm pleased to share that there are indeed 14 x 6-pin PCI-e connectors, as originally advertised by Bitmain. The APW5 does appear to be capable of supporting 2 R4s with a single PSU (using 220v power).

From what I understand they are 7 pairs of connectors so each one is split. So depending how long the splits are, is there enough slack to run two R4's? If each R4 uses 7 PCIe connectors then one pair has to be split between two R4's and if the splits aren't long enough there might not be enough slack to connect one pair to two different miners without some kind of extension. It certainly doesn't look like you can stack these R4's. I guess you could use the extension on the pair that powers the control board and fans.

Nice! That is a lot of connectors.

As far as payouts and mining BTC, would it be perceivable that someone could create an altcoin that could be worth while to merge mine with BTC or one that wold be linked to the pool that would award the miner when a BTC block is found.
There are already several established altcoins that are being merge mined with BTC. However, they are not popular as they used to be so this might be the reason you may not heard of them if you are new to mining scene. Either way, it wasn't really changing anything. The income from merge mined coins for breadcrumbs to be honest.
Recently there are several efforts to use bitcoin blockchain as a security to other coin's chains, but a solid project may yet to come.
The most popular coin with merge mine was Namecoin.
You can refer to this link if you want to learn more about merge mining.
I use www..litecoinpool.org..it is always UP ...I have not had backup pool set for 2 years lol ....he merge mines and keeps that and there is NO fee and because
of merge mining pays out your mining in LTC at 103% rate...has nice calculator and tools also/graphs
so no issues ..but has the benefits to me of kinda merge mining w/o the hassle and that 3% w/o a pool fee is equiv of say slush at 4% MORE to you over the fact of a say
regular 1% fee scypt pool ...all lumped in the basket.
Yeah, cutting the fees and giving a little extra payout rate seems good. At the end of the day though, merge mining won't be enough for these machines to have reasonable ROI anyway. I guess OP's idea was to maximize the earning for a fast ROI with merge mining. It would only cut a week in a year long ROI.
It's funny how Bitmain markets the miner for "home miners" while those are the ones with the highest electricity fees. They should rather market them as "hobby miners".

I still think that the best thing for bitcoin developers is to go back to the drawing board to GET RID of ASICs altogether and either develop around plentiful GPUs that are pretty much a commodity OR make a node-based POS scheme which alts are toying with. The first option is much more preferable to me.
Barring this , the conversation goes like this:
Miners: Can we get a 1 year (REAL) warranty?
BMT: No, but you can pay for the unit that will breakeven in 350-400 days (it is so pretty and quiet; your cat can doze off on the top of it).

It's very unlikely that anyone can come up with a algorithm that can not be someday integrated into ASICs. If the algorithm makes money, there will be development for ASICs.
Spreadcoin (SPR) had a great idea of preventing pools, but that would only make farms compete at a greater level. The equal and fair distrubition purpose would not again be achieved.
PoS on the other is proven not to be a great idea as rich seems to get richer and the incentive to run a full node with low coins is not appealing as it should be.
I've also been thinking about a solution for this. Not expecting for BTC to achiev it, but at least a altcoin that could progress through Proof of Work and keeping the distribution as fair as possible and beyond the reaches of companies.
I'm sure this miner is great and all but it's just a ripoff. Sad part is people are actually going to buy it anyway.

Don't forget PAYPAL has a business master card which i have, you can use, but not sure you can with butmain, they don't take CC yet ? , I'm aware of, unless you do it the PAYPAL way, link a CC and Pay that way, which I do a lot, and have for years, i was one of the first to sigh up for paypal back when they offered 5 bucks or more for signing up .when the service seemed like it was gonna fail, don't know if anyone here remembers those days . well any way im getting off topic .

Yeah I have a paypal business card.
I could get the gear on that and expand coverage to,six months .
I have done more then 500,000 in eBay sales and I have done more then 150,000 in purchases with my eBay card.
My eBay name is philipma1957. And have more then 1500 positive feedback so with zero negative.
So I would like bitmaintech to allow PayPal.
I also have PayPal credit and could get six months to pay for an r4.
It becomes rather annoying to not be able to do business with bitmaintech in a more normal,manner.
I am mining with 20 gpus and 8 pc's about five thousand worth of gear.
All with one year made into two year warranty. It is better to do this and simply convert the eth to btc.
Mostly due the fact the pc gear holds value and has the two year warranty .
Right now the economics simply say gpu mine.
Bitmaintech needs to figure a better warranty or more will simply gpu mine.
I think something will happen soon.

-Items purchased for resale, professional, or commercial use.
THAT might be the killer. Remember, per the Judges in the KnC lawsuits -- Bitcoin mining generates income. No matter how limited, that constitutes being a business so is commercial use.
cusal mining is considered a business according to the US tax law unless that has changed.
Here in the USA the IRS does not consider coin mining automatically a business.
They DO however require that you report all income derived from it and pay taxes on it. Since sizeable exchanges of BTC into my bank account as fiat will be reported by Coinbase and my bank anyway, I do declare that to the IRS.
BUT - If you do setup a 1 person private corp to mine coin - that opens the door to being able to write off the cost of hardware used per-standard depreciation of office equipment - specifically, computers along with being able to itemize/deduct other aspects of the business. Again, consult a tax attorney on that.
Oh, and purchases made on a Corporate Card by nature ARE covered on the cards warranty extension plans
