Avalon 6 Vs Antminer S7, which one you will choose?

[notlist3d]

My only issues with Zoomhash are that their warrentees tend to be crazy-short, and they tend to be pricey....

seems like you loose factory warranty?
Could be a downfall if this is so. ...

Actually Avalon is a lot nicer then bitmain on their warranty.  Bitmain a sale through 3rd party kills warranty.

Here is from blockc -

4. Warranty Registration and Transferability:

A. If still within the Warranty Period, Avalon Manufacturer’s Warranty will transfer to the buyer, upon equipment resale provided that the buyer contacts Avalon or BlockC.co to register as the new equipment owner.
B. In order to receive Manufacturer’s Warranty coverage, you must notify Reseller with your contact information, the equipment you are operating, and a description of your operating environment.

So just make sure to contact when buying a machine is how I read it.  I imagine you would need order number (proves it's still in warranty) and other info from original buyer, but most I think would be ok giving it i they are selling you a unit.

I am liking the look of the Avalon 6. I guess this is old news, but looks to be 2 hash boards, each having an 18 chip, 2 chips / node string, so 36 chips / board, 72 chips total.





For some reason websites seem to be saying 80 chips, also several report the GH/s at 3.5TH wheras I think it is 3.65GH/s?

Does anyone know if these guys are ok? http://asicminer-shop.de/Avalon-6-35-TH-s_1 All looks and sounds legit, but you never know?

Not bothered about noise but if someone can confirm to what degree these can be undervolted / underclocked I might just go for one?

We just got our Avalon 6.

[wlefever]

Nice eric@haobtc!  Ya'll just keep expanding!  Will like to see once you have all of these A6 up, and running.

Still running as many S3's, or upgrading to more efficient hardware?

I am a bitmain fan so i have to go with the S7. However the avalon looks very nice. I think I will buy just one for testing purposes.

It's not good to depend on 1 party.

it is good to have 2 or more s-7's

along with 2 or more Avalon 6's

that is assuming you can provide 4400 watts and cooling.

The pdu in my garage can do 30 amps derate to 24 for safety .

24 x 240 volts = 5760 watts.

I can do 3 s-7s and 2 avalon 6's   pull 5600 watts.

May be too hot.

ZoomHash has them for $1449.99 shipping next week.

Andddd I am thinking about it! That's what I was looking for an easy single purchase not a MOQ or a group buy pain.

Isn't Zoomhash currently at the center of a lot of legal and business drama?

At their checkout, you can use a credit card or Paypal. I guess this would be enough protection.

I have never had an issue ordering from them.

They seem like a pain on shipping, hopefully since it is coming from US they won't gouge on it but I am not going to hold my breath.

It is coming from the USA.

Warranty is from the manufacturer at 90 days.

I'm going with a few S7s. The main things that kill it for the Avalon 6 are:

1.) It requires a RasPi controller.

2.) It uses more power than an S7.

3.) You need more physical units to get the same hashrate.

4.) It costs more per Ghs than an S7.

5.) Avalon did me dirty on delivery and cost me 10-100Btc back in 2013.

6.) Bitmain has always taken care of me in every way.

I really don't see why I would be better off splitting mt order between two companies when my S7s have been all running flawlessly for over a month now and have already returned about 1.5BTC each. That's about 25%-30% of what I paid made back already. If I had ordered Avalons I'd still be at square 1, with a 10% diff increase taking a huge chunk of my ROI yesterday to boot.

Some of your things are just wrong.  The Raspberry PI controller is a pro... most would agree with this.  If your controller bricks or goes don a RPI is easy to get back up or get a new one quick.  S7 you need a custom controller board. So Avalon wins with using RPI.

It's actually pretty close as far as efficiency to S7, neither are really that far from other.   And Avalon has been able to be overclocked to 4T, we still have not seen a underclock yet but Phil is trying a few things to get one. 

Also consider it only takes 4 PCI-e cables so I was able to use a ATX psu I had sitting here already ROIed on.  On S7 the 10 PCIe cables makes psu selection much smaller.  I think Avalon wins on number of PCIe cables as it opens door for many more PSU's.



I think yours all comes down to no 5 on your list.  And I can't blame you if your mad over losing BTC back then.  But the company is now Canaan-Creative not avalon making the miner, and they got rid of some of the top level people.

On this everyone is welcome to their own opinion. I have dealt with them on 4.1's and it went good.  And on Avalon6 dealt with BlockC and it went good.  So I have no big complaints.

But all my personal opinion I could be wrong if others don't agree with me.

I have seen in another thread that the S6's run at 74 degrees, that seems a bit hot.  Mine will be in tomorrow, can any others report what temps they are running at?

There is no such thing as a S6 .   I'm guessing you mean Avalon 6?

[RichBC]

I suspect this debate has some way to run. If for no other reason because the S7 is still evolving   and the Avalon6 is still very new.  We do not yet know the detail of the 135 Chip S7 changes or a later release of A6 firmware. Both have yet to show their true colours in the Undervolt Underclock stakes, which for me will be very important.

A few thoughts, questions & comments from someone who has neither at the moment.

I like the simplicity of the S7 built in controller, but did load the Avalon Code into an RPi this Morning and it looked very similar. I see the argument about the S7 controller going down but surely there must be an interface board of some Sort in the A6 to go wrong?

Have seen the comments on the A6 temperature and agree that being in the 70's does seem very hot / hotter than I have chosen to run a miner. Is this the set / design temperature or is it a consequence of people turning the fan down?

I much prefer the rear connections & 4PCI-e of the A6, makes the S7 look a mess. I also prefer the "conventional" single plate heatsink over the sometimes poorly stuck mini heatsinks in the S7.

So for me at the moment too close to call

I agree it's early that is part of why I mention I'm still testing in my review thread.  There are still a lot of possibilities.  And a lot of people do have a favorite mining company and get use to it's software, I can understand this.    I just personally enjoy trying multiple companies it's part of the fun for me.

As far as controller Avalon 6 will win with RPI.  I truly wish bitmain would use RPI instead of custom controller.  If you get a bad flash or electricity outage, internet outage, etc.   The S7 might be a brick till replacement.  As with the Avalon 6 I have RPI's in my project area I can go grab one.  So it hands down will win on controller.  I will be honest I hope one day bitmain uses RPI instead of custom and this becomes a moot point.

As far as you mentioning a boards within the miner I'm sure there are some custom boards that could bring it down and need a new part.  No miner is 100 percent unstoppable that is part of reason of warranty is to test out miner and make sure it's not a dud.  But a board within it I see as different part then controller. 

I have only bricked one bitmain controller but it was not fun and enough to make me like RPI option.  So I could be jaded from my experience of bricking a S3.

I assume you are talking about my statement.  Also, note that was with a manual fan setting that also reduces the overall hashrate.  If you want to get the 3.5TH/s with the current firmware, you will be looking at a 79 degree temperature.  If that makes you uncomfortable (like it did me) then you will probably be looking at closer to a 3.2TH/s miner and you should use that for your calculations.

However, it is also important to note that these are brand new and a new firmware is scheduled to be released to address these issues.  I am anxiously awaiting that firmware update and will do a review once it has been released.

I chose the Avalon over the Antminer due to the noise level.   I'm getting about 3.3TH with EVGA G2 1300watt PSU.  I hear you can get 3.7-4TH using higher voltage Server PSU.   The Avalon 6 in my garage at 3200RPM is silent thru the door and not ridiculously loud like the Antminer S7.   Noise is a major concern for home miners.   The PI Controller is also very nice as it allow me to just do the configuration just once and only need 1 IP address / network cable for the entire daisy chained group of Avalons.  Very happy with my purchase and I'm actually going to order another 1 which will help keep my living room warm for the winter.  It only have 1 FAN vs 2 on the AntMiner S7 hence why it's so much quieter and I can use ATX PSU which is silent vs the Bitmain 1600W PSU which is quite loud.  Another awesome thing is that it only require 4 PCI-E connection vs 10.

But the Avalon 6 is so expensive, i'd think you'd be better off getting a S7, dropping the fan speed to 20% and underclocking, for less noise, more hash, better efficiency, better price?

[QuintLeo]

At this point, I'm still choosing "neither", as RoI is still VERY problematic at anything over 5cent/KWH power rates.

 I'm hoping the B-Eleven or whatever Innosilicon comes out with ignites some price competition, but it's starting to look like that will happen too late to matter.

Damn kill the dream (13c kwh)


Also knc has another 20mw BTC data hall going up in a few months (probably 2-3)

Bitfury says it has a 40mw data hall going up NEXT WEEK

http://businesswireindia.com/news/news-details/bitfury-launch-energy-efficient-immersion-cooling-data-center/46537

fun times for difficulty..I just can see getting an Avalon 6 at the price and or with my 13c kwh ...add this other stuff ...very daunting indeed
