0) General Information + Hardware Needed to buy
The Avalon 4.1 miner is a solid miner from it's metal case to it's performance with under clocking capabilities.  In the worlds of Avalon "Avalon4.1 – 1.3T consists of 40 A3222 chips, with improved heat dissipation, which can be controlled by Raspberry Pi or TP-Link TL-WR703N."  Below is list of items you need to buy in addition to miner.  Ofcourse some of you might have these in your parts pile and already be a step ahead.

• Standard power supply with 4 PCI-E 6 Pin adapters (up to 1000 watts depending on setting, also at underclocked you only need 2 PCI-e cables(One on each blade).)
• Raspberry Pi or TP-Link TL-WR703N
• Network cable

1) Unpacking
The miner had a decent sized trip from from EHash to my door in middle of US.  It was shipped via DHL and made it to my door in 5 day's. First thing you will notice is a box.  Mine made the journey without any problems as you can see below.   And in the second picture you can see it was well protected with styrofoam around the miner.


2) The Miner
Below are images to showcase the miner.





3) Install
The install is not hard at all with the guides posted on EHash: http://downloads.canaan-creative.com/people/lili/doc/controller/

First you will need to flash either a Raspberry Pi or the TPlink.  I personally chose raspberry pi as I had one laying around.   The main guides I used were:

1) The Raspberry PI SD flash guide: http://downloads.canaan-creative.com/people/lili/doc/controller/Raspberryreflash.doc
2) The Raspberry PI settings guide: http://downloads.canaan-creative.com/people/lili/doc/controller/Raspberrysetting.doc

As far as a general guide you will reflash your Raspberry PI with a pre-made image of a custom DDWRT install for the Avalon hardware.  After flashing you need to connect to the Raspberry PI.  In my case I had to log in and change the IP address to 192.168.1.X IP.   I would say it's a 15 minute install if you don't have any trouble.  I did run into some trouble and Canaan-Creative does have a great support team and they helped me though it.

4) Running
For these results I am running at a under clock

Avalon 4.1 running with settings shown below:
MM Ver   Chip Freq      Voltage      Hashrate          Power usage
4.1       420:390:360    7625         980G              542Watt        *A special thanks to philipma1957 for finding these settings Link to more settingss (https://bitcointalk.org/index.php?topic=951758.msg10425635#msg10425635)

• Below is the advanced GUI showing the miner running:

• A Kill-A-Watt showing watts used:

• The air temperature before and after being sent through exhaust:

• Sound:  This miner is crazy quiet with a underclock and fan at default of 20 percent.  I went to take a YouTube video to show off how quiet it is.  I had to turn off my overhead fan, my projector, and close my window.   And still could barley hear it.  Link to video: https://www.youtube.com/watch?v=d7UTdo_4AaQ

5) Conclusion
This was a perfect fit for me getting ready for summer mining.  I was able to run it at a under clock making it a very efficient miner. The heat exhaust is manageable even though winter is over for me. The install was easy with use of the guides, no big surprises during my install.  And only problem I had the support was great and nice to work with.  It seems to be built with a solid metal case, and solid performance.  The biggest surprise was how quiet this miner can be.  It is the first miner I actually put in my bedroom and cannot hear it across the room.   I have other miners from big and small, water cooled, and nothing is comparable on so little sound.  I will keep it running and post how it goes overtime but it is a very good miner from my experience so far.

In this review we have went over most of the technical spec's already.   In this section we will hook up multiple Avalon 4.1's.  They will be running the same under clock mentioned in first part off the review. Below are parts needed in addition to parts in first review.

• Standard power supply with 4 PCI-E 6 Pin adapters.  Power depends on what speed  you will be running the miners at (In my under clock each extra miner you need to add a PSU with over 550 watt's also at underclocked you only need 2 PCI-e cables(One on each blade).)
• USB Hub to connect 3 to Raspberry Pi

1) The Miners
Below are images to showcase the miners.




2) Install
Adding a miner is extremely easy.  You have already done the setup in the first review.   It was literally as simple as plugging a hub into the Raspberry PI, and plugging the Avalon miners into it. Below is a picture of Raspberry Pi with a hub and 3 miners plugged into it:

Thanks for the review notlist3d

Can you tell what the cpu usage on the Pi is while mining?

Also what is the noise/temp like at 1.3TH?

Thanks

Thanks I appreciate the nice words.   I am running a old RaspberryPI Version B. Looking at CPU usage it is sitting around 97-95 percent idle it appears most of the time.  Cgminer is using the most CPU power I have seen it jump to 7 percent only a few times it's pretty solid at 2-3 percent.  This is running with one miner, looking at stats it has a lot more power to do multiple for sure.

With it being summer temps here I did not do much much on the 1.3 TH.  It did get louder where I would not want it in my bedroom at that speed.  I personally am amazed at how quiet it is.  I'm running at around 950GHs.   You could go down even more to ECO and do with even less fan.  But the speed I'm at seems to work great at a ambient temp in mid 70's so far.

I run 3 avalon 4.1's  on my rasp pi model b  the one that uses the sdcard not the mini sdcard. I use a good 8gb sdcard like this
I run them at 850gh each and use 1400 watts .  I use a evga 1600 p2 psu

total 2550gh using 1400 watts.  very happy with this gear it is quiet.

when summer comes round I will drop to 1500gh and 700 watts

Well done @Notlist3d.  Appreciate the review.  Youtube videos are always a plus.  Enjoy your new miner.  Now if we could find one that doesn't generate heat! :D

Has been over a day now and is still running like a champ.

Thanks for the review. I'd have a few of them if they weren't so overpriced.

This.

They look & perform great, but like you say - the price just ain't right  :(

Nice guide - great work!  :)

Yep. They'd sell by the boatload if they were priced better.

yeah a 3 pack to the usa gets a shipping break,

 but  total is 6.63 btc   or 2.21 each

a single to the usa is 2.45 btc with the shipping.

right now they are the only new gear in stock and shipping.

bitmaintech sold out batch 5.

Thanks philipma for breakdown.  It is true with 3 pack you get best deal.

As far as comparing it I would compare it more to a SP20 then S5.  It's underclock is great.  Also it is built out  of solid metal.  And the most impressive thing to me is with this case and fan it is the most quiet asic I have ever had since day's of USB's or Blades that made no sound.   My projector has a louder fan then this thing in hot weather.

Yeah you can run it anywhere without sound issues at 900gh it is really quiet. 

at 750 gh it gets better watts per gh and is close to silent.

 I grabbed an ebay deal on one I am still waiting for that one to show up.
I got it for about 325 usd (I had a 13% coupon) it is due on April 13th.  I suspect this one may be an ebay claim rather then an ebay deal.
If it turns up and works well I will post here and my thread on how well 4 run on a rasp pi model b (big sdcard model)

I am happy I am able to share this.  A thanks to valkir

Member valkir is working with Avalon's marketing.  He is able to get you a few percent off.  It varies on what current percent is so I can not give a estimate.

But if your thinking of ordering you might hit up valkir: https://bitcointalk.org/index.php?action=profile;u=214808

Thanks Notlist3d

Im working hard for you guys! Speaking a lot from America with China to get better deal!  ;)

Let me know still got some fews coupons!

Cheer

Valkir

That's definitely the right price for running them at good w/gh speeds.  I'd grab 4 at that price myself.

Yah the price would need to be near Bitmains S5 now to regain anything at all.  Too bad their price point is a $100 more than what's feasible for us to buy it at.  It looks like a great product due to it's solid compact build and especially the silence.  Wish this would have come out at the end of the last year.

I was hoping to keep a day log of it running.  It ran perfect no problems until a storm took out the power for my house.  So starting back at 0 hours. 

On day 3 at this point.  Weather has cooled down some so miner is doing great.  I can't even hear the fan right now at all.  You will see cold weather let RPM go down ever more.

It did do a restart as my house temporary lost power during storm.  It was no fault of the miner, but that is why time up is not on 3 days.

I really wish

1) They would of included the controller inside the case like an S5.

2) Was priced cheaper



I don't understand why they don't just mass produce this miner, sell it cheaper then Bitmain's S5 and make millions. Instead selling small quantites but larger profit margins.

Well I cant argue on price.  I would love to have more of these if it drops.  There are some things that are not comparable with S5 such a the quality metal case.   They have been able to utilize the case to make it very quiet. The S5 does not come with a metal case enclosure, but that saves you money.  So it has plus and minus either way you go.

I can say is the external Raspberry Pi is actually not bad at all not being integrated.  It would actually be nice if you had multiple miners having them all on the one controller.  Most important thing is it being stable for me, and so far the raspberry pi with their custom image does this.

I would consider their external controller a success after testing.  I have had others such as a SilverFish 28 were the sharing of a controller was a pain and caused stability issues.  So far very stable and no control issues.  It is also nice knowing if I ever need another controller I can get a regular Raspberry Pi and not some custom controller.  That is a huge plus to me.

The rasp pi is rock solid with 3 miners.  I have a spare rasp pi and 3 spare  pre programed sdcards.

I love that it is an external controller.

Brick a controller  on an  s-1 s-2 s-3 s-4 s-5  c1   and you lose your gear for a while.  Well if you have 2 s-5's you can run 4 boards on 1 controller.

All spondoolies gear the controller dies the gear is dead.

I would like 4 pools not 3 pools
I would like the balanced pool option to work.

But the truth is just make them cheaper.  A set of 3 for 1200 usd shipped not 1600 would be good.

Well I'm not getting the summer weather quite as much as I thought it would be this week.  It has been a good test of going through quite a bit of range of temperature.  Tonight has been the coldest with an ambient temp of mid 50's outside.  It is the lowest RPM the fan has gone.  I can vouch that the miner has did a good job with a changing ambient temp.


*Turns out time was set wrong, has been fixed. Noticed it when looking at image.  In future will show proper time.

Apparently until they get the price right or deliver a better product ahead of the competition we wil be hit with a higher price.  Avalon isn't geared up and able to afford huge runs of chips and components until they have a winner that makes profit to do so in the future.  For now they have to stick to small quantities and higher prices.  Better marketing would definitely help them and other suppliers not just one.

Looks like around midweek I will be able to test again in more ambient temps of "summer" mining.  We had a cooler week this week so it was still cooler the most of summer will be.   But will be mid 70's to 80's to come soon.

Summer is indeed near and avalons gonna kick some heat out of them as to the old avlaon units do kick out some heat and need goo cooling.. You might want to do some mods to the units them self to see if you can channel airflow better and get some air cons running in room to drop temperatures down as best as can get. Or use for heating at night if cool open doors across the house and channel it with pipe work and have free avalon heating xD

I still have some more things to try out.  I have been happy with testing right now it has been easier then I planned with colder weather then I expected.

But I am happy with results of running the Raspberry Pi with the custom ddwrt Avalon image.  It has been very stable.  I don't think I will even try the TP-Link as I'm so happy with Raspberry PI.

On a side note if you do go TP-Link route make sure to get the newer model: TP-LINK TL-WR703N  I thought I had 2 sitting in my part's but TP-LINK TL-WR702 has no usb besides the one to power it. So no full usb to connect the Avalon to.

More to come with this review.   Today I ended up moving it to one of my mining areas.   In my room I had it in the corner to close to wall heat was building up from exhaust going at a corner in 70ish degree ambient.  Nothing dangerous just uncomfortable when windows were closed.  The summer weather seems to finally be coming.

I moved some miners around. Now it is sending exhaust outside and seems happy :).

Have my summer plan drawn out.  Still need to work on it and buy some things.  But the exhaust system will be enough for my "hobby".  Just wanted to make sure I was not paying for AC on my miners.   

This miner will end up there eventually. I'm guessing it will take me around a month or so with free time to complete wiring, fan's and exhust.  Will be first time I have not put miners in multiple areas.  It's kinda on back burner not my main project right now.

As far as this review hopefully within the next 2 weeks or so I will have another one or two to test and show multiple working together.

so the power connectors are bridged on each blade; sp20 has 1conector for 2asics

how many units can you connect to a Raspberry Pi?

does the miner have a buzzer? like the s3....

The two blades each have their own PCI-e power connecters.    If you OC'ed you would need all 4 but since I'm running a underclock at around 550 Watts it just is not needed.

On units you can control Ehash describe it as "You can also manage 13 clusters by connecting controllers to USB HUB, with hash rate up to 152T.".   In real life I was running 1 and it used around 3 percent of CPU of Raspberry PI.  In next week or two when I have another to test with I will give a better idea of what happens to Raspberry PI with more then 1 unit.  (I am thinking it's safe to say it's more then a individual will ever use, but I cannot verify that).

No buzzer that I have heard also it would take away from the quiet if it had one.  The usb cord and front panel let you know if it's working fine with using the lights.  Also if you had a bad unit, and lots hooked up in the software it allows you to turn off the led so you could find which unit it is.

Could you elaborate on the "exhaust" that you have worked out? I completely understand the idea of exhausting the hot/warm air. What is it replaced with? Outside air? Or is replaced with AC cooled air?

Sounds like a very engineered miner :)

Maybe in the future i will own one or 2, but the efficiency will be worse with newer miners... time will tell!

Currently my miners are where AC can be used to cool them down.  But I've started to get quotes on electricity to put them all in one area.   

If I have all in one area my plan is to use enough CFM to keep hot exhaust going out and replace the air.   I current plan is a high cfm fan to help it work.   One duct bringing in outside air, a inline fan up in air taking hot air and it leading to a duct fan to exhaust.

This could change greatly as i get it done and see how it works in real world.   And if all else fails I can leave miners where they are but then AC is being used.

It is a very well engineered miner.   As far as current gen it's hard to beat if you go to the extreme overclock not many can go to .4X range.   I currently am in .5X range as it seems pretty well balanced on getting around 950 GHs and using not to much electricity.

I am preparing a little bit ahead.    In next week or two I will be testing more then one. So today one of my goals was to test a usb hub.

I ended up going to my parts closet and found a 5 port usb non-powered hub (generic inexpensive hub).  Plug it into Raspberry Pi and then the one Avalon 4.1 I have into it.  Worked perfect It's now mining away on a hub, did not slow down mining or any bad things.   

they can daisychain using only 1 usb port.

I ran 3 all daisy chained 

Just plug them in chain like Philipma explain!  ;)  You can run up to 127 avalon in chain.  ;D

I don't think a Raspberry Pi USB does well with an unpowered hub. The power that a Raspberry Pi USB port can supply is very limited. While it may have worked with 1 device, and the hub itself, adding devices will just drag down the +5V that the Raspberry Pi tries to supply to the hub. Maybe the Avalon is REALLY low current and it will all work just fine. I just know things get unreliable real quick when the +5V on a Raspberry Pi isn't nice and well regulated at 5.0 (or a smidge higher). I had a variety of reliability problems with a Raspberry Pi setup and a hub, and they all just disappeared when I supplied the hub and the Pi from an ATX +5v line. Fighting power problems is REALLY frustrating in my experience.

That might be a issue if it was a USB stick miner and getting power from it.  But it seems to work fine with a unpowered with one perfect.

Hopefully in a week or two I have the more units and can confirm it works fine with regular non-powered usb hub.  But if needed I have a few from the ASIC Miner stick miner days in my parts I can use.

They promote these miners with "Avalon4.1 4.2T Suite". Okay, 4.2 Th.... They also write: "Mining speed can reach 1.3THs". So 3*1.3=3.9 Where are the missing 0.3 th/s?

So in the best of all cases, you get 3.9 Th/s for 6 BTC. But still have to buy PSUs. Has anybody ever reached 3.9?

Okay  these miners are all about quiet not hashrate.

I can get as high as 1.2th but like spondoolies  sp20's higher clocks burn more power per gh.

So if you have free power and want to overclock them tell me I will do a 2 unit 6 hour overclock test for you.

I am at 1637  and 880 watts for 2 units as sound is my absolute most important issue.  next is power I am at 0.5375 watts a gh

here I am on a freq 20.94 2 unit under clock

http://imagizer.imageshack.us/v2/1024x768q90/911/WriH9G.png

If the noise is the issue, they should promote this - but they do promote the hashrate. It's as if I sell you a house with five rooms, but you see it has only four, and the seller tells you with some bricks and skills, you can build a fifth room - maybe. But never mind, the main issue is that the house has four doors.

Okay I tell you what I will set it higher and see what we can mine.

I bumped freq from 20.94 to 26.74  I am running 1 not 2 units.

http://imagizer.imageshack.us/v2/1024x768q90/912/sNDTOd.png

But don't burn your house down! I don't want to have trouble with your wife!!!

 Yeah neither do I!!

2 units now 2 psu's each about 800 watts so 1600 watts total for 2300 gh   or .69 watts per gh.

So just like the sp20  power use jumps faster then the hash rate.

I was 1600 gh and 860 watts = .5375 watts per gh     I am not sure I want to push past the present settings.  note I cranked the volts to 8625.  gear is still pretty quiet

Now   2308 gh and 1600 watts = .69 watts per gh

http://imagizer.imageshack.us/v2/1024x768q90/538/Seb2Ix.png

Quick shipping from Ehash.  Now I am up to a set of three.  It is working good it appears by just plugging them in usb hub.

Have some testing to do so I can add more info :)

Sweet!  ;D I wish I had 3 avalon!

So you went to the hub and did not daisy-chain?

Correct I had a cheap hub.  Just used it.   It's a non-powered hub.  So far it seems to work great with the 3 of them.

So far the 2 new miners are working great with the first one.  Below is a image of the three running a little underclock.

yeah that is a good speed mid 900's  > I am doing a speed test on my 2.

these start pulling a lot of power on the higher clocks.

note the volts are set at 8750  that is 9.375 percent over stock of 8000

I just wired 1 socket for 240 volts about time.  I am using an evga 1600 p2 for 1 unit and an Intel server psu 1200 watts at 240 volts along with 94% efficiency.

It is still not too bad for sound, I think I could squeeze out 2650 or 2700gh for 2 units ,but  the power cost makes it a dumb thing for me.
I know some people want to max gear due to free power.  look at my errors and my temps  these can do more then 1260 each like they are doing here.

http://imagizer.imageshack.us/v2/1024x768q90/661/kyH5dT.png

That is a nice speed on 2 units.  I to can't make it work out with price of electricity.  I was able to get all 3 of mine on a single 110 circuit with underclock.

I'm using gold power supplies, but still very happy to get it all on 1 110 circuit.  I am looking into changing a lot with my summer mining area.  Still working to add airflow, I want to run this summer without using AC on miners.

Yeah I am losing money or breaking even, but I will do it for a day to help people get an idea of the top end limits.

Nice findings.
Looking forward to your results on the 1.2TH area. findings....Could the Avalon be the one that should be standing next to my SP20 `s ?

Been testing 3 for a little less then 24 hours.  So far running great as far as stability.  Again I am using a Raspberry Pi to control them, it is working out great.

More to come I have been documenting this from unpacking till now.

Three Avalon 4.1's so far happily mining together.  I would consider very stable at this point.  Need to add some lighting I appolgize it's darker then I originally thought.

nice are they the silver or black models.

All 3 are Silver 4.1 models.  I will get better pictures tomorrow with more lighting.

I am able to report been running for three miners for three day's and have been very stable.

I have added a review showing 3 Avalon 4.1's running - https://bitcointalk.org/index.php?topic=1008726.msg10946156#msg10946156

Today they are running in some of that 80 degree summer heat.  So far doing great.  It turned out to be a great week to test in summer conditions.

I
am testing low clocks today.  still using my 120 volt power as I am able to do volt/watt reading.

 589 watts for the screenshot below  so 589/1200 = 0.49083 watts a gh

Thanks for sharing philipma1957.  It does a nice job on under clocking. I was happy to get 3 of them running on 1 110 breaker.  Still have not made jump to a 240.

Still running great.  Very stable it's running great in the cool morning air.

I finally got all parts needed to do in house 240 volts  correctly.   I will post results on my thread tonight.

They used to be industry leader but now they mimic the design of SP20

It might appear to mimic the SP20 long design but they actually are very different.  The case is more of a capsule for lack of better term.  It is opened from end where fan is, leaving top opening like SP20.

The biggest difference is the one fan implementation  in the Avalon 4.1.  They were very concerned on noise and made it very very quiet.

Agreed. It's actually nuts how silent they run at around 800 GH/s each. Literally have to check the miner sometimes cause my gaming laptop is louder and i cant hear it running. A pleasure to own!

the 2.1kg between sp20 and this miner, i guess, is mostly aluminium...
it's also the wattage difference
maybe the fan is better noise wise...

that's y the reduced noise!

It is a rock solid case on both miners.  On the Avalon 4.1 it just seems they put a real effort to find a quiet miner.  They managed to do it with one fan running low.  It's hard to believe it's running from across the room.

The SP20 is a great miner to, i love them.  Only thing is they are quite a bit louder.

It's official 3 units can make it through a few 80 degree days.  I still don't have good solid 80 degree day's.  At night in high 60's.   

Will make sure to update on how it deals with ambient temperature.   So in a day a range of high 60's to mid 80's and all three miners working good.

It's been a little while since a update.  Currently I have 3 Avalon 4.1's running together.  They pull around 550 at the wall with gold power supplies.   Using a RM1000 to power one, and an EVGA 1300 for powering other two. (I had these laying around is reason I used these PSU's).  At wall they pull around 550 each.  So were looking at 1650 at wall.  With my 20 amp breaker I am able to run this on a 110 circuit, but it does not have room for much else using that power.   With this currently I am able to get around 2800+ GH/s  .  This is shown below:

I am doing 2 right now pushing at them pretty hard. I have two giving me
I am using the 240 volt pdu and the new 240 volt circuit right next to the breaker box.

the amps read 6.2 on the pdu meter so 6.2 x 240 = 1488 watts  I am using my big 1600 watt evga plat psu.  so 1488/2260 = 0.65 watts per gh which sucks but I am getting overpaid on nicehash renting so pushing the gear up to  this level still earns more.     these units will go as high as 2400 even 2500gh but my 1600 watt plat would fall just short at 2500 so I left head room.


http://imagizer.imageshack.us/v2/1024x768q90/538/xvyz28.png

Thanks for sharing!  That is nice seeing them pushed to that.  The ability to change the speed so much is very nice.  We can run a underclock for normal mining, but if things happen such as nicehash/westhash paying so much they can be pushed.

I'm all for gear with a nice underclock, it really gives you a lot of options.

yep and I posted photos of it using the 240 volt outlets and the pdu


https://bitcointalk.org/index.php?topic=1024540.msg11147119#msg11147119

With the this week westhash was paying good amount over straight BTC.  I used the 3 miners for a few day's they did very well.  Below is a screenshot:

Bump for Teferi66's troubleshooting.

This show's 3 being set up with a Raspberry Pi.  Once getting first one set up, it was as easy as using a hub and plugging in other 2.

A little over a week and a half of running a set of 3 Avalon 4.1's.  It's amazing even with three the quiet level they achieve.  There is not another miner that matches it on sound.   Yes it's a premium price for this though.  So pro and con.

I have turned up the fan's just to test them out.  You can make them where you can hear them if you turn them up.  Most would be insane to do this, but I have ran it with higher fan's a few days.  Really no positive effect to make it worth while.  Still same speed with underclock, and temperature is fine either way.

Below is a nicer and longer frequency chart that has been put up on the ehash site.


I personally come closest to the 542 watt usage on the three setup I am using, as underclocked I get a better electric efficiency.

There is a new youtube video for the Avalon 4.1 on the Ehash site.  But it appears site is having problems.

Once site is up I will link to the youtube video.

Site is still down.

A good link to check if sites  are up or down is below

http://www.isitdownrightnow.com/

I'm not sure what is going on with them.  The site is definitely down.

I get a "Error establishing a database connection" so almost makes me wonder if it's a decent sized problem.

Still down more then 16 hours.  I will post back later to night.  Just got back from a party and I am just a little blitzed.  Do not want to make a mistake with posting.

The error sounds bad like they made website with wordpress.  It is able to connect to the IP, but there just is not a proper site up.   So either they are updating, or there is a problem with site. 

Up and working I was able to use all pages I checked.

Thanks philipma1957 it appears it is back.  Below is the new ehash video for the Avalon 4.1.  Click picture or link:

I hope this video helpful.

Thank you for the video.  It is very well done!

Particularly like the choice of music as I find it relaxing.

Listening to this miner is just that relaxing.

Would not mind a coupon for one more via pm if possible, better yet a coupon for a 3 pack would really be nice.

Nice video!  ;D

I thought it was good aswell :)

Been running in summer conditions at this point.  80 degrees outside.  Using a fan to cool down where they are, but all 3 still mining great.

Review has been added to the Avalon 4 Wiki - https://en.bitcoin.it/wiki/Avalon4#Links

anyone selling these in the US?

You can buy them new direcly from ehash.com  ;)

they are nice quiet gear.  pricey but they are the quietist miner I owned.  I ran my 3 pack at 850gh each for 2550-2600 gh it used 1300watts on my 1500watt evga platinum psu.

If my summer power rates were not 18 cents I would have kept my 3.

I kind of regret selling them.

They are pretty amazing on sound.  There really is no other miner that compares to it on sound.

They do charge a premium though.  I keep hoping one day it drops.  I really like them.

I know, I don't want to pay their ridiculous shipping fee though....maybe we can get a group buy going? They have 80 in stock so if we buy like 20 they will probably give a discount and shipping will end up being like 10 bucks each. 

If the price was right I have no doubt there would be sales.   It really is a great machine, and very quiet.

As far as a group buy you or anyone is welcome to contact Ehash.   I have no idea if it is possible or not.

They just quoted me $370 for 40 units, plus shipping. I will see how much shipping is and see how much better I can do, but would need a lot more interest if this would be serious to go through. I would take around 6 of them so would need people to grab the rest of the 34 units.

Make sure to mention that they are not shipping to same place.  As shipping would very.

I think shipping would be hard to estimate if you ship 40 unit's to different places that are unknown.

The whole point of a group buy would be to do a drop ship in the US and distribute from here, otherwise they will still charge .5 btc shipping per. Shipping in the US will cost around $10 a unit.

Normally the point is price per unit to do a group buy.   If you choose to do a drop ship in my opinion you will have trouble with group buy, unless using a very very well known escrow who agrees to do all the shipping.

And 370 is actually a nicer quote then I thought you would get.   Compare it to 1.96 BTC.   Currently that beats it by quite a bit.

Looks like 430 WITH shipping to US is best price I can get out of them. Wanted to get it to under 400 to make it worth it, considering you can get a single S5 shipped for 390...

But you will need to mod the S5 heavily (and still I don't think you will get as quiet).  They are full metal cases aswell.  So add in factors such as this in price.   

They are really two very different miners.   430 is pretty darn good considering you just asked them, and it's a rather small group buy at 40.  If you had the 80 they mention in stock, or even 100 interested it would effect price.  But unless you can reach those levels 430 is a deal as far as the Avalon 4.1's compared to past pricing.

Well I will probably start a group buy thread in the forms, and see how many interested people we have.

I miss mine put me in for 1

it is about 19 pounds.

my zip is 07731

let me know if you need escrow help

At matching prices the Avlaon4 is extremely well matched to the S5. Higher power consumption but higher overclock, more flexibility and auto voltage. And as nolist3d said, no need to mod it to keep it in the house.

Group buy thread is up at https://bitcointalk.org/index.php?topic=1059637.0

Post there if your interested!

bah just noticed there is an actual group buy subform...moved post to

https://bitcointalk.org/index.php?topic=1059712

ill update that thread with all interested members

Best of luck with the group buy.  I hope it works out.  They really are very very high quality miners.   And I cant say enough about their operating with very little sound.

Bump for the group buy going of these.  It sounds like a pretty good deal if they get to 40.  Cheapest I have seen at least on selling.

As always use escrow.

Avalon 4.1's have officially been sold out for a bit.  So this review is most likely for used gear at this point.  For what it's worth I still have 3 of these running great.

I have had a small amount of communication.  That and site makes it look like the next product from avalon will be a small usb based miner.  Most likely the "Avalon Mini".   In time we should see price.

Yeah the group buy never panned out before all new units were sold.  Love this miner. We may be waiting on a price for used units, but at the rate things have moved I wouldn't bank on seeing anything.

Looks like until Avalon brings out a next gen miner, we may get a few of these 4.1 minis. Just wish they would post a price already!!

Avalon 4.1 has now been removed from product page. - https://ehash.com/

Now they seem to have focused on Avalon Mini - https://ehash.com/product/avalon4-mini/

They still show up in the shop though, just out of stock. https://ehash.com/shop/

And WTH is up with no mini price?

I think they are still working on it.  I'm guessing we wont see price till it's ready to ship/close to ready.  Will be interesting to see.

I'm not expecting any new 4.1's to show up, but I always could be wrong.

I have exchanged some  emails with them    about a review model of the new mini  and a group buy of it .

Review model = late July

group buy = Mid- August

But time will tell if they can meet the times above.  They did get me a model of the 4.1 for review very quickly. So I hope they can come through with the mini on time.

Bumping to help with - https://bitcointalk.org/index.php?topic=1184817.new#new

Probley the lowest price your going to get a 4.1 at.   I have been condensing miners. Just lowered the price of a set of 3. 

http://www.ebay.com/itm/Avalon-4-1-x3-Kit-Each-1-25-TH-s-3-75-TH-s-Bitcoin-Miner-Faster-Than-S5-/322001366064?

Free bump if only you were not as far.  :-\

Thanks and yea on this one you will want to be a US buyer.  The 3 together are heavy and add packing to a box that can hold all 3.  It is expensive.

But I have best offer turned on.   If you ever wanted Avalon 4.1's throw in offer.   They are the most quiet full size miner I ever have had. If you are a dorm miner or mining in a room these are still one of the best options as far as sound.  So if you have access to cheap/free electricity might be worth a look.


And the ebay auction is for a set of 3.... so you get the full suite of 3 Avalon 4.1's. 

I bought a 4.1 last week for 149 us in btc shipping paid . waiting for it to get here on Thursday according to ups. kind of why I asked you what I did in a PM but then i found my answer a few hours later .:) .if you do happen to break up the set i see it in time i might buy one . right now, I'm saving coins in hopes of getting 2 or 3 of the 16 nm ones if one ever comes to light . but for now I need something to do and pay cash for cheap ones then mine with them , it gives me something to do sense, I'm  disabled and  i can't stand up long etc.

Yea I am probley going to sell this one as a set.  Just is easier they have been a set since they were bought long ago.  Also makes it where it has the RPI that comes with it.

On this forum  it's not a big deal, but on ebay selling one without a RPI set up can be trouble as it seems to have more new miners.  Lowered to as low as I hopefully have to .... 385 shipped for 3.  Your getting Avalon 4.1 x 3 for the price almost of S3's.  

It's still on ebay.  Only looking at US as don't  really want to ship this big box out of US.   Also don't want to mess with customs for so little. - http://cgi5.ebay.com/ws/eBayISAPI.dll

I saw it on Ebay , i hate buying out side the US any way not because of shipping, a lone it's just a pain and takes to long most of the time  ..That is a nice price for sure.
I just don't have that in cash right now and won' t cash in my coins :) or use them.

I have one coming like i said  and Polly looking to buy another one next month they should be good till July at least .

Cya .

Sadly the shipping was a heck of a big box and heavy with 3 of them.  It did sell via ebay, just waiting on payment now though it.   Sorry to anyone that had offers in.

With difficulty change these are machines to look for if you have free/cheap electricity.  Great quiet miners, I expect to see more being sold from others.
