Topic: Bitmain Announces the Antminer R4 and APW5 Power Supply, Designed for Silence - page 46. (Read 85063 times)

my guess 1.7btc for the r4.

but I doubt the pricing is gonna be "competitive"

sad but true.

GL to B1 buyers.

Power supply is extra. Best estimates are $1000 for the miner and $300 for PSU (may change.)

Well If I want to heat up a room it's nice but I'm not sure about running a bunch of them in the same room and been able to get the heat out easily. Looks like if the unit stand as in the image, you got the heat to move from floor to the roof. So If i want to throw to the heat through a window (without having to suck it up with another fan/system), i would have to flip the unit so the air flow goes in the windows direction.

Just thinking out loud.

900W eh.. Hum... Well it can run on one home circuit without too many issues this is really good.

Argh I wish I had free power...

Very tempting... hum..

maybe  maybe not but if you down clock the s9's  most likely yes.



I am a gear head most likely will order it .

I think a slight under clock to it will allow it to be truly quiet.

As an aside  the controller looks to have four slots  so a carefully thought out mod may allow for expansion to 3 or 4 boards.

Seems interesting to me.  I liked the S7-LN miner aside from the crappy used S2 power supply that they included with it.  At least with this one you can get it without a PSU and run your own PSU.  At 8.6th and 0.098 j/gh we're at about 850w plus the controller and no idea what their fan uses.  I'm guessing 4 PCIe plugs plus one for the controller board.  A 52 db 8.6th miner sounds great to me assuming the price is reasonable.  Unfortunately with zero competition I'm guessing the price is going to be to high for me.

$300 for a 2600w PSU sounds great, but for those without 220v and stuck on 110v, $300 for a 1300w PSU isn't that great.

Last I heard CK's opinion on it, BFG started as a fork of cgminer and stole a lot from it. Maybe that's changed, I dunno, but he wasn't happy.

Kano has said a lot about bmminer, and some folks have run string tests on the compiled program and found its contents were nearly identical to cgminer. Given Bitmain's penchant for doing as little work as possible to produce a functioning product I'd be surprised if they wrote their own thing from the ground up, especially since it was built for basically the same hardware they've already had a crappy fork of cgminer on for about two years.

They put a year warranty on these at a year ROI and I'd take a chance.....90 days ....ouch.....just saying...

(would make a fine space heater for the winter in the basement)

I'd think that CK has decompiled it and checked. Has he said anything specifically on the matter?
Giving it its own name and ergo claiming ownership goes way beyond being a fork and if the case then CK would be screaming about it from the rooftops.

Just using some of/maybe most of the API's for CGminer and CKpool which have become the defacto standards for pool/miner operation doesn't make bmminer a blatant copy. BFGminer is similar in that is uses many CGminer API calls but it is certainly not a fork of it.

Just gotta hope the guys at corporate don't look too closely at bmminer and realize it's a potential liability being a blatant closed-source fork of a widely-known open source project.

miner software authorship and/or whether bmminer is a clean re-write of CG miner aside -- I've been waiting to see something like this from Bitmain or others. Long over due. Give it a snazzy looking case to look like AV gear and they will have a winner for the techno Bling crowd.

Reason: I'd bet beans to btc that they are eyeing the large department store market. More specifically the ones in Asia as a whole at least to start.

Their main hypermarket stores to a Western eye are -- insanely huge. Rather like department stores used to be before malls became the rage in the 1960's. Think Walmarts, large furniture/bedroom store, massive consumer electronics sections, groceries and eat-there, you name it, all together. The one I visited in Korea (I think was a Lotte Mart in Daegue) even had their own moped and car dealership inside. All in one massive 8-story building.

In late 2014 before he cut all communications, Joshua Zipkin owner of AMT (now aka Joshua Alexander) was talking about him drumming up extreme interest from a Korean chain for his last-ditch efforts to keep AMT alive. Well at least be able to finally dump the scads of A1 chips he had... It should be in the Skype AMT room chats linked in my sig, somewhere around maybe late July or so.

As for the home decor aspect -- I see a nice market for custom cases there. Also looks ready made for branded casing by oh, say, a department store chain... This also goes a long way to explain using bmminer & custom controller board in the latest batches of s9's. Corporate buyers for stores are not known for looking at products using open source hardware/software. They want lock-in any way then can get it.

So is the PSU included?

seems interesting although i have no current plans to buy any.

one thing from the official page that stikes me odd: https://enshop.bitmain.com/products/antminer-r4-silent-bitcoin-miner.html


they show it in a living room. seems pretty fugly to put in a living room, you know, with the psu and wires and such

this power supply can power 2*S9 in 220V ?

pricing... i think most will be upset but it's gonna sell like hotcakes!

nice & innovative design but fan replacement will be pita. no aftermarket that can be sourced easily.

So, it's about the same power draw/Ghs as the S9, and you get a little more bang for your buck (the current batch of S9 goes for $1600 hashing at 12.93 Th/s)

If the specs and everything are true, then this could actually be a viable miner, if they don't have cooling problems with all the chips. I do like the rack design, and this could be a great miner for servers and homes alike, if only they provide on time and the first batch won't be grossly overpriced like most of their miners have been, and if they don't somehow run out of stock and turn the prices up...


They seem to be looking to expand their customer range with quiet miners; my family doesn't trust bitcoin and thinks it's all a acam, so I run my miners at my own house. The hashrate and efficiency is actually pretty good, considering most of their specialty products have been older chips.

The link is working ok.
Nothing about the warranty though.

Is the warranty 90 days as usual?
Will the price be 1000USD for the R4 and 300USD for the APW5 like in the product pages I saw?

Mining software is most likely Cgminer -fork "BMMiner" like with the S9.

Weblink is down.

Warranty? (if any)

Cost?

Miner software?
