I self modded this thread. Just tired of threads getting messed up with a lot of bs.

I got off to a rough start yesterday as no software sdcard was included and no controller .  I have a rasp pi and after a day of getting a blank sd card and loading an image to it. I have the avalon 4.1 running.

Right off the bat it is truly very quiet gear.   the current meter readings are under 53.6db


I am pulling 688 watts with stock settings.

 I used a open-wrt img

sent to me via pm by Valkir.

 I want to thank valkir and canaan -avalon 4.1 for the demo and the chance to  review this.

I did 1 change I went into the advanced settings and put volts to 7975 vs 8125

this makes the fan run at 1100 rpm db is now at  40-42db watts are at 687 on my kwatt meter

will post back later on.

  That is stock setting and I like you am not a shill. This is the first avalon of any kind that I have owned

I have much more to come on this unit.  Here are some screen shots in eco-mode.

 eco mode allows for  lower power

also look lower left at blue change theme it switches to the simple skin

http://imagizer.imageshack.us/v2/1024x768q90/540/6Twe1S.png

see this the hash rate drops from 1010 to 976.  I have yet to check the watts.

 then on the simple skin advance goes to the plainer  skin in the first photo.  a lot of pages and settings to explore.

http://imagizer.imageshack.us/v2/1024x768q90/673/oFI6Vz.png

Now I am going to just let this run in eco mode.
I am running it in kanos pool.

eco mode gets 500gh at 244 watts  this is .488 watts a gh at the wall very good
 sound =39db
volts = 0.6625
freq = 12.21ghs

normal mode gets 1010gh at 687 watts  this is 0.681 watts a gh at the wall it is quiet enough to use in an office instead of a electric space heater. As an owners of s-5's and sp20s they are not as quiet as this.

sound - 45-50db depends on room temp
volts =0.8000
freq = 25.27

custom settings for volts  and freq are allowed .  

so the goal is finding the best middle numbers.

I saved your post as a quote. I will delete it

saved for more photos and how to shots. I deleted two posts but saved as quotes. going to let gear run over night on eco mode

Happy to see you got one of these.  How does it seem to compare to SP20 on electric efficiency?

Too bad the controller is such an issue, would be a perfect noob home miner otherwise.

Its still pretty much plug and play when purchased with a preflashed Pi. Not as easy as an SP20 but compared to the Blade / Cube days its relatively straight forward.

Ah, got it. Thought it was more involved than that.

Thanks for the review, Phil. Looking forward to more stats!

I like the very quiet noise on it. This should appeal to more "home" miners which should help keep the network more decentralized.

My biggest concern though is that the "eco mode" gets roughly the same efficiency that the latest miners of Bitmain get at stock levels (plus you should be able to under clock the S5 to get even better efficiency by under clocking it) (and only marginally better then the SP30). Someone buying this has a greater chance that profitability will cease for continuing to run it "soon" which decreases the potential to achieve ROI with it.

(LOL I know you are not a shill, however you had posted that you are tired of trolls) - also a tip would be to create your OP, then make several additional posts in succession that are "reserved" that you can later edit.

edit: if the price (which I was unable to find) is low enough then it could potentially be a good deal, however it would still need to compete with the secondary market of other miners with similar efficiency

Okay real fast on eco mode it gets .488 watts a gh very good but so far eco mode locks me into 244 watts and 500gh

they should send a sd card preflashed for your rasp-pi what a p.i.t.a. to flash an sd with a mac.  gave up purchased a reader/writer for my windows 7 and flashed an sd card in under 30 minutes.  works nice with a rasp pi. setup is very easy with a rasp pi and a good sd card.

back to efficiency this is a great office miner.  it is basically silent under 40db which is no noise at all.  so if you are a free power guy but must be quiet this seems better then the s-5 or sp20.

I am running 2 s-3's in my friends office at 2.4 cents a kwatt this is a good replacement for them.

more to quick seller   the s-5 is a tweakers delight .  there are 10 or more fan setups I did mounting setups and when sidehack comes out with a voltage controller (95% or so) the s-5 will be even more tweakable then now.

This is a set it and forget (at least I hope it is) .  Once I fuck with the custom setting and figure out the best numbers to use it will sit and mine quietly for a long time. It has a place for some of us.

It is not for a 10 miner in the garage setup.  Or any bigger farm. 100 in a barn 50 in a warehouse space.

 But the guy that really needs peace and quiet this is the one. I will figure the best you can do in the next few days on the eco or custom end. Efficiency wise.

https://ehash.com/product/avalon4-module-1t/

It looks like they are charging 2.15 BTC plus .29 BTC each shipping when buying 10, for a total of 2.44 BTC which works out to roughly $536 each when buying 10. When compared to both the SP20 and the S5 it appears to be more expensive while being less efficient.

I have been doing settings under customs

Chip Frequency(Default: 450:390:370) >>>>>>>>>>>> 420:360:340

Chip Voltage(Default for 4.0: 8125, for 4.1: 8000) >>>>> 7400
 

this gives me : 891 gh watts are not settled give me a few minutes

my efficiency numbers are much improved  557 watts over 922 gh = 0.604 watts per gh vs 0.681 watts per gh

to really get highest gh with lowest watts will take time. 

  922gh at 0.604 watts and 40db-42db  has real value for an office setup.   please be patience  with me as I am not familiar with avalon.

my 420:360:340 = freq 23.44 which runs at 0.7375 volts

http://imagizer.imageshack.us/v2/1024x768q90/538/4J9a1y.png

@ Quickseller

please read my thread above you.  my style is post and then alter post with more info.  you are too fast. I dropped watts per gh from 0.681 to 0.604

so far stock freq   and  a few  custom freq  this chart will be slow to develop maybe 3 days time



450:390:370 = 25.27  and 0.681 watts   per gh  volts get stable at 0.7775 volts

420:360:340 = 23.44  and  0.604 watts per gh   volts get stable at 0.7375 volts--------this seems to be best for now it is late will set this for the night



410:350:330 = 22.83  not stable with 0.72 volts will try again with 0.7300 volts

410:350:330 = 22.83  and  0.618 watts per gh   volts get stable at  0.7250 volts
400:340:320 = 22.22  and  0.631 watts per gh   volts get stable at  0.7125 volts

Really glad to see Phil doing another review. Personally I hope every manufacturer sends Phil a unit moving forward. I have pointed countless people to his SP20 thread. I would like to get one of these since they are silent, but the price is just ridiculous.

Also feel free to delete my comment  ;)

they are not geared for your setup. these are an under 10 miner setup where power is cheap and silence is the biggest concern.

no mods needed to be really quiet.

I am going to do more test with freq guesses and volt guesses I will fill a chart out for people to use on the custom spot

This setting is a lot better then the stock setting as it improves efficiency enormously. The hash rate decreases roughly 9% (some of which could be short term variance) while the w/gh declines ~11.4%. If I were running this myself then I would stick to this setting until profitability at these settings were to cease then switch to "eco" settings.

LOL sorry

His reviews tend to have the most relevant information while a lot of other reviews tend to have a lot of "fluff" with unimportant information

This is probably a huge plus for the avalon 4. From what I hear the SP20 is very loud, and the S5's I had in my apartment were really too loud, I would wake up almost every morning around an hour before I had to because of the loud noise

 ::)

Not a "p.i.t.a." unless you're doing it wrong. For future reference: sudo dd if=/path/to/file of=/dev/rdiskX bs=2M

http://elinux.org/RPi_Easy_SD_Card_Setup#Using_command_line_tools_.281.29

thank you will check this out.  the link you gave I used.

 I used 3 youtube  videos  none of them   used bs=2M at the end of the command most likely why I could not get it to flash .  most said use bs=1M or bs=1m

going to be busy today with a cable upgrade.  will have a few hours down time. I will try to burn an sdcard on one of my 3 macmini's today.

 370:310:290 = 20.39 0.568 watts per gh this is freq 20.39

 this is doing 772 gh at 439 watts  silly quiet under 40db

dropped off to 762 gh at 439 watts  still that is 0.576 watts so  quiet I am really impressed.

 If someone built a case you could house 2 of these and run them off a 1000 watt psu

cheap low cost no. well built really quiet yes .  you know people that say I want to support the network does not matter if I make lots of money.  this is your miner
the setting above is pretty efficient. the unit is really quiet with no mods. This allows you to balance the pool choice.

I can run kano's pool ck's pool and f2p pool. supports ck and kano gets steady money.  allows me a shot at a block. lastly the wife won't hear it make noise.

Your review are always awesome.

Im glad I manage to get you one.   ;)

 Thanks oh I figured out why I had 2 devices.  I had plugged in two cables to the a-4  one is all that is needed the second one allows a link to the next unit.  I now have 1 device

Excellent review again Philipma! Your SP20 review is what sold me. I would sell my SP20s and convert to these new Avalons in a heart beat if the price was better. I currently move my SP20s in and out of different rooms via a mobile shelving unit to deal with the noise. Even with a large group buy the price is not competitive. Price needs to come down before I'd consider making the switch.

yeah the price point here  is high also add in a rasp pi.

when you figure this out it is viable for a 'free' power guy that absolutely needs quiet.

My home now has
1 Avalon-4.1
1 s-5
9 sp20's

I can't use  avalon-4.1  in bulk purchase my power costs are too high.


I can use the sp20 in bulk as I can manage  the noise.

I can use the 1 avalon-4.1 in my friends office as it will replace the pair of s-1's I have had running in his place since July.
 Power is 2.4 cents a kwatt in his office.

 I can run the  new gear for 9 months or more. Sell the s-3's at a cheap price on ebay. Making the a-4 a natural upgrade for me.  But it is a 1 unit upgrade not a 9 unit upgrade.
I look at this gear as a specialty item. Not right for everyone.

Biggest flaw is price.

I can get it to .61 watts at 830gh
I can run it at 500gh and do 244 watts that is really efficient really quiet. but costly.

Still like it a lot.

nice review...lets see how much better efficiency we can get...sorry for not responding sooner
For a better ECO mode use 340 with 6875 this gives me 431W according to APC 8)

okay read macgyver007 thread and reply to me here.

I decide to burn a second sdcd card.  set it checked it it works.  now I can really play with this machine and just pop in the second card to my rasp pi if I truly trash the settings.

I realize the custom settings are easy and I did this twist.

1 freq number only 340 which is 20.75ghs or should be about 800gh


http://imagizer.imageshack.us/v2/1024x768q90/912/8XRCdJ.png

it works but has lot of errors and needs more then 0.7000 volts

http://imagizer.imageshack.us/v2/1024x768q90/540/kmMZrW.png

post above shows a simple way to set custom but i underpowered it so I set same freq 340 = 20.75gh per chip = 800 gh and gave more power

better results  with added power 7125 vs 7000


http://imagizer.imageshack.us/v2/1024x768q90/673/DS5nEO.png


less errors higher hash
http://imagizer.imageshack.us/v2/1024x768q90/538/VooDIa.png

so on custom   340 for freq  7250 for volts and false for auto volts looks rock solid

this is easy but it appears that custom setup does not give the same watts per gh that eco does.




 Choice of modes I picked custom


http://imagizer.imageshack.us/v2/1024x768q90/673/I0l2Mn.png

on custom I set freq 340 - 20.75 gh = 800gh  volts = 7250------- I used false for auto volts--- I go to see dh errors and decide if volts are good

http://imagizer.imageshack.us/v2/1024x768q90/673/HutZy1.png

this is getting really good error numbers

http://imagizer.imageshack.us/v2/1024x768q90/673/uvOj3M.png

I like the form factor of these a lot more than the S5, but I just don't see how this can be competitive vs the S5 or the SP20. A three-pack of these is BTC6.39, or $1405.80 + shipping. Meanwhile three S5's are $1110 + shipping and three SP20s is $1195 with free shipping.
The only possible benefit I can see is lower noise vs the others, but then if you downclock the SP20 to Avalon4 levels you can run at 10% fan where noise isn't a big deal either, plus the SP20s are a good bit cheaper.

so custom and 340 at  7250 volts gives best dh rate

next is 330  = 20.15gh a chip at 7000 volts

http://imagizer.imageshack.us/v2/1024x768q90/633/XdnJm7.png


I would have thought I would have a higher hashrate but dh is really low


http://imagizer.imageshack.us/v2/1024x768q90/905/ObBYA1.png

This is truly quieter then the sp20  not really close.  I have sp20s at 6% fan speed  and it is quieter then the s-5 delta fan  mod at freq 312. It looks better then the s-5.

But it is costly and is more of a show piece item for your office. For me I  will use the one piece to replace 2 s-3's at my friends office.

I also believe  as a concept piece for space heating it is a winner.

A smart company that builds space heaters need to look into this tech and consider making a Delonghi miner/space heater.

http://www.delonghi.com/en-us/products/comfort/portable-heating


I will continue testing the custom part of miner config's

When you go under 340 for frequency strange things happen just try 339 and you will see....
I think the key here is auto volts and why we have a discrepancy with results...my pool results from 6875 are after 2 hours reporting the same hashrate on miner and pool 431W rock solid as originally the miner starts around 810 and drops to 793ish also after 24 hours roughly the same
when I edited the ECO mode, its still using auto volts which from what I see is the upper (max) voltage limit...give it a whirl by editing your eco file or change auto volts to true...and remember these units throttle power on a cycle

Right now Im using 400:370:340 with 7250 less errors more wattage...

Is this quieter then the S3s?

    yes unless you swap out one s-3 fan put in the silverstone 141 as the pull fan and downclock to freq 193

   that  gives you about 380gh and the  s-3 uses around  300 watts.

the 2 in my friends office  are clocked to freq 212  have the stock fans and are a bit noisy.

 I am getting 830-850 gh using 680 watts. that is .8 watts a gh for my current s-3's

   So 1 of these will do more gh  use less watts and be quieter.

   I will set it to do 900gh use 560 watts.  that will be .61 watts a gh for the a-4.1

I will sell off the 2 s-3's cheap on ebay.  It will work because he spends 2.4 cents a kwatt on power.

spent a long time doing customs as the settings

found a very good setting


849 gh  dh  errors  = 0.565%   I am using 492 watts = .58 watts per gh


I like this setting.  If I swap this with the pair of  s-3's at my buddies office.

 I get the same hash rate and drop power from 680 to 492 watts.



http://imagizer.imageshack.us/v2/1024x768q90/673/8wvBeG.png

 here are the settings

http://imagizer.imageshack.us/v2/1024x768q90/537/eXZ9aK.png

Absolutely, the incredibly low fan profile even overcools so you can cap fan speeds even lower.

   yeah with the custom settings of



Chip Frequency(Default: 450:390:370)                      360:355:340
Chip Voltage(Default for 4.0: 8125, for 4.1: 8000)          7250
Automatic Voltage(Default: True)                                      True

the results below fan is 1100 rpm quiet but if you ssh in and set it slower the unit is still cool enough.

I get 840gh use 460 watts  about 0.55 watts a gh and  38-45db with stock fan.  I am done with custom setting tests for efficiency 0.55 watts and 840gh is good enough for me.  Tomorrow I tweak fan settings.

http://imagizer.imageshack.us/v2/800x600q90/538/i8Eqyk.png

Alternatively you can just set the max fan RPM to 30 [or around there for 1200rpm] if you know ambient is going to remain sensible. Ie don't cap the RPm off then put it in a 50C farm :P

Either way, 1100rpm is quieter than a Cube. I've missed this.

I am running my s-5 and the avalon-4.1 In a spare bedroom.  The window is open ½ to ¾ inches.



This gear would really clean up if it could be sold at a lower price point. It is truly quiet the  fan at 15% is under 1000 rpm

The settings I have finished with:

Chip Frequency(Default: 450:390:370)------------------------------------------------   360:355:340

Chip Voltage(Default for 4.0: 8125, for 4.1: 8000)-----------------------------------  7250

Fan%(Default: 20%)----------------------------------------------------------------------  15

 gave me  this over night    watts are 460-470 at kwatt meter that is  about 0.56 watts

sound meter was 38db to 42 db
 
This miner actually is a true home miner the sound levels are wife friendly so when all is said and done I can keep these custom settings for now and then keep this miner on stock eco mode for the summer.  Use it to mine solo to keep in the game.

that is 500 gh and 244 watts = .488 watts a gh

http://imagizer.imageshack.us/v2/1024x768q90/633/06ushb.png

Are these setting accurate:

wall power reference(W)     hashrate(GHS)         comment
400                                  800                       echo mode
570                                  1000                       normal mode
950                                  1300                       turbo mode

Assuming they are.  I can run 2 Avalon 4.1s using my Corsair ax1200i power supply at normal mode.   Is that right?

On Normal mode what is the dB at default settings?

Also for reference, what is the dB on turbo mode?

I will be putting these in my office so i want to make sure they are quiet

There are no settings to achieve those numbers in the real world with the factory firmware which is:

250W 500GHs eco mode
~650W 1000GHS normal mode
there are some in between frequency and voltage settings for 450W and 500W (not defaults) which give 850-900GHS more info on that in this thread and my review thread
450W 850GHS
500W 900GHS
I have not gotten around to turbo yet will tackle that tomorrow
As for quiet, using either of phils or my settings for 850-900 range you will have guaranteed quiet and even on stock speed its quiet just not as efficient :D

db should be under 45db.  you will be borderline to do the corsair AX1200i   using custom settings,  the stock settings you have are not accurate.

Now I have the older firmware as I go with if it works  with old firmware don't ever do new firmware until 3 or 4 others show it works.

The firmware I have does eco mode :

  244 watts    and   500 gh

My custom setting does  840gh at 470 watts

my results have been very stable using a rasp pi  older model B

Can anybody post what are the settings for "Chip Frequency" and "Chip Voltage" when running in ECO mode?

Furthermore, can "Chip Frequency" be modified at any interval? Is "Chip Frequency" directly related to "Chip Voltage", is there any table for all possible combinations of  "Chip Frequency" and "Chip Voltage" (combined)?

chip frequency is directly related to


chip frequency setting on the custom page
I use 370:360:340
Default is 450:390:370

use custom
Set your volts to 7750
use auto voltage =true.

and then tinker with chip frequency setting  you will get lots of results for frequency. auto volts will find the best volts for that freq.





volts can be set at:
 8250
 8125
 8000
 7875
 7750
 7625
 7500
 7375
 7250
 7125
 7000
 6875
 6750
 6625
 6500


I do all custom settings.  I don't ssh.  

I found with volts on auto the software does the work. my current custom setting is :

http://imagizer.imageshack.us/v2/1024x768q90/538/7sCI9J.png

I get this result and use  480 watts to do it.  this is 480/854 = .562 watts a gh

 if I go to custom I get 244 watts and 500gh that is .488 watts a gh .  diff and price does not require me to do eco right now.

CrazyGuy may do a group buy on these.



https://bitcointalk.org/index.php?topic=612390.msg10585048#msg10585048

I decided to order today.  So I purchased a second avalon 4.1


 valkir   helped me get the demo one and was helpful in ordering a second one today.

I will post how 2 run on my rasp pi.  I hope to  get it some time next week and do a series of photos and tests with 2 running vs 1.


I may order a third one and do a 3 machine set of tests.

 I have to say once again this is really quiet gear.

 I may end up selling off my sp20s and my s-5 and just keeping 3 or 4 of these for the summer.

Yes, and while there is winter it makes a great leg heater ;)

https://bitcointalk.org/index.php?topic=7216.msg10594502#msg10594502

Mine already is, max clocks and still silent (with a fan RPM cap). Quieter than any PSU I can put it with other than an RM1000.

I am going to shift to these over the next month.   run them at 850gh using 480 watts each. and when the summer comes set them to eco mode at 500gh 244watts each.

I will try to see if they are stable with 2 then 3 then 4 units on the rasp pi.

Im also looking to do the same!  :P

Currently looking to buy one more Avalon  ;D

I got coupons if you need more.

Cheer

Valkir

Valkir

what is the deal with the coupons?

Trends

It was 3% and now should be 5%

Im waiting for the new coupons.  ;D

PM me for one! Its free!

I went to order more today had trouble doing so about 1 hour later

 valkir  I got your pm explaining the issue.





I got an email from ehash saying 1st order was paid for. I am hoping this is a good order. as I do want to show a 2x machine setup.

http://imagizer.imageshack.us/v2/1280x1024q90/540/6QIyr2.png

I got tracking for the new miner.  I will look to do a long followup on this as a 2 miner setup very soon.

any news on this new review?

Avalon still making acis miners. Wasn't aware they where still making asics any more. Looking at their cost of equipment and hashing speed and power use is stupidly expensive. 1300watt for 1.3TH can go  grab me an antminer s5 that is 1.1TH and using 500w at most. 1/3rd of the energy use don an avalon machine. If avalon got their act together from being the first to release asic technology and asic miners to reducing theri energy used and then having a good miner they would again have a good miner. Right now their way over priced and way under energy effective

I would normally delete your thread as you are leaving out a lot of info.  Or telling partial truths.  But you are a legend  and I respect that.  

 no antminer s5 uses 500 watts at 1100 gh

  the avalon 4.1 or the sp20e  both burn power like mad when pushed

yeah the avalon 4.1 burns 1100 watts at 1.3th
but this miner  burns  510 watts at 900 gh  and it is whisper quiet.  
this miner also well burn 244 watts at 500gh and is basically silent.

 the s-5 is  460 watts at 885 gh and is 70db without fan mods.
the s-5 is  600 watts at 1150gh and is 73db without fan mods.



Right now 1 company has new gear in stock Avalon 4.1  cost is high and you have to clock it to 885 gh  but you get 42 db.

The avalon is the only true "home" miner  on stock sound.

I own
sp20e
 sp20
 s-5
avalon 4.1
 s-3

If you have an office space and silence is important this is your miner.

If you have a  barn or a detached garage the s-5 is your miner. but  it is sold out and not available new.

If you have an attached garage   the sp20e may be your miner.  but it is sold out and not available new.

Indeed however the cost and energy used for the miner in UK is a big thing for me and right now I turned off all my miners given the ratio of energy used to generating BTC to brake even point and futures is not effective any longer. Lot better to buy BTC and wait or go on some hash cloud that is effective or a place where has free energy or little costs for energy to be used would be good but right now cost of energy in UK for mining is not good.

Do they offer us a discount if we purchase multiple units? Has anyone attempted a group purchase of these miners to drive the prices down?

I am high for the usa. 13 cents winter - 3 cent heat gain = 10 cents.  and 16 cents in the summer + 1 cent for some cooling = 17 cents.


but uk is 25-35 cents  that is just brutal.

If you want a coupons, contact me. I have some.

Cheer

Valkir  ;D

valkir helped me to get both units.

Second one is due today according to DHL

US is not bad but yeah UK is brutal for mining now with the price increases and wont budge. Can get business rates cheaper but still then need business to do from and to be honest way diff is going up on BTC and price it is not really worth mining. Maybe if BTC goes up and energy prices down to liek it was in 2013 and 2014 when mining was ok. It would be good again to see that but very doubtful.

Yeah UK and  a lot of Euro miners are crushed by   high power and VAT.    Right now this thread is a decent option

one or two from lee.  You can use paypal and get some protection that way.

https://bitcointalk.org/index.php?topic=934581.0;all


Back to this review the item is in my state of NJ and should arrive by 6 tonight.

I pay about $0.20 in the winter here in southern California, we have some expensive power! :(

Man that is some expensive rates even with mine at somewhere close to that but managed to get me price down to £0.15 inc VAT or so and looking at other business to get cheaper so it roughly about the same as what your paying in california. energy company's need to get their act together on prices and look at more solar stations and have free energy that way and clean renewable energy like turbines for water falls they can produce so much energy FREE but the problem is economy around it and the natural wiled life being effected maybe they should look into making their own artificial ones across the nation would work few pumps to pump it round from one section to another and they got a system that generates energy all the time free. None of this nuclear waste stuff.

 You have one of the worst other then Hawaii , maybe Alaska .

Indeed welcome to rip off brighten and the tax man adding tax to everything that the tax man can. We had good petrol prices a few weeks back and that has now gone up and is due to go up about £0.80 due to how cheap it went, nice knock on effect of cheap prices and pay much higher later in the year.

A  problem for many people tax tax tax tax tax tax tax .  oh  a license fee  not a tax yeah right.

Some times I sit and look at how many taxes I pay not the $  amount the different  types and it is very impressive  more then 35 types of taxes.

Yeah too many different taxes. If it was a tax free world or we could have access to all the tax paid over the years the world would be a better place and less poverty and less people on the streets. But no the tax man has to have his cut and seems nothing ever gets done with it correctly. Correct me if am wrong its just like ROAD TAX we pay it and expect good roads yet we get nothing but crap and pot holes and bad roads to drive on. and tax on wages well I sort of agree on that to an extent as do insurance for free health care but even that is not free cos paying somewhere else out of wages. Tax free would be good or a reduction in it would solve a lot of problems. BTC even getting taxed now its a fking joke lol

The new miner arrived. It is silver not black.  So I now have 1 silver and 1 black. Slightly annoying as I prefer a matched pair.  They look close in stats.  The silver one has slightly higher error rates. Still very early in my testing.


I am pulling 989 watts.   989/1798 = around 0.55 watts a gh at the kwatt meter. These run on  the same  rasp pi.  I will need a day to post photos. Still very quiet for 2 units.

close to 1780 gh for 2

http://imagizer.imageshack.us/v2/1024x768q90/913/cB3r8o.png


close to 1798 gh for 2 at the pool

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

989 watts for the rig or is that across the both on same plug if for tone at close to 1.8TH is not bad going but still its a fair wack. What was ya cost for the unit. Is it even going to brake even on RIO on it is the big question tho.

Nice so its really plug one more in the chain and it work or you had to do some workaround ?
Can wait to see the pictures!  ;D

I am using a hub .

Did you try to put the Avalon in chain using the cable the give with ??
That could be nice to know if it work.  ;D

yeah I will set that up next.

993 watts on kwatt meter
that is for:
 the hub
the rasp pi
the fan under the rasp pi

this way works the gui reads differently but I get my 1700 plus gh at 990 watts or so




http://imagizer.imageshack.us/v2/1024x768q90/661/ru2N1c.png

About time for me to get one I think...Thanks for all your guys/gals hard work out there with these reviews and such.

valkir has coupons

I have been doing deep under clocks with my pair of avalon's

while hash rate is much lower with these underclocks I am getting down to .4 watts

this setting is giving me .4 watts a gh .   I need a day of testing, but if I stay consistent I am buying a 3rd unit.   Will post in a bit.



http://imagizer.imageshack.us/v2/1024x768q90/540/lo1kpJ.png

don't forget update to latest firmware (MM and cgminer), we are continue improving.

https://en.bitcoin.it/wiki/Avalon4

I am looking to expand to 3 units.  I have a question about rasp pi  I have this one it is the older model b  works great I want to get a newer rasp pi



http://cdn-reichelt.de/bilder/web/xxl_ws/A300/RASP_NOOBS_01.png

this is the B + will it work with the software?


http://static12.insales.ru/images/products/1/3015/36105159/raspberry-pi-model-b-plus.2.jpg

They should all be backwards compatible.  I have 2 rasp 2's and they are so much quicker. 

so you are running your avalon 4.1 's on the newest model 2?

I will order one from amazon today

I am also going to get a third avalon 4.1


http://www.eeevolution.it/wp-content/uploads/2015/02/eeevolution-raspberry-pi-2-model-b-3.jpg

ordered the third one

https://bitcointalk.org/index.php?topic=779612.msg10756641#msg10756641


I am going to order a new quad rasp pi on fri from amazon. this model

http://www.amazon.com/gp/product/B008XVAVAW/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A30ZYR2W3VAJ0A

along with a better card

http://www.amazon.com/gp/product/B00IVPU7KE/ref=ox_sc_act_title_2?ie=UTF8&psc=1&smid=ATVPDKIKX0DER


will get back with this info soon.  maybe all setup by Mon or Tues.

Don't forget to let everyone know the total all in cost and what sort of ROI potential you have underclocking.

Months? Ever?

yeah! they beat us with the quantity of miners, made with our own money....

i like that is full of aluminium and the temperature will never reach 120C even with a silent fan...

so how many units can you place on 1 raspberry pi?

I have 2 soon to be three.  I am also getting the better new rasp pi to test.

@ bick  they can do 1793gh at 1020 watts with a small underclock that is about .57 watts at the k-watt meter

they can do about 985gh at 445 watts  this is at a strong under clock and that is .45 watts at the k-watt meter.

I have a need for a space heater every winter to keep some pipe from freezing. 

The space heater would use 1000 watts  and cost  80 bucks.

I would run it 90 days a year.

 So that is free power for a 1000 watt miner  90 days every year as long as I stay in my home.

These units are very close to perfect as space heater replacements.

So limited use no ROI.

Buy BTC everyone or better yet a small efficient heater.

Mini Portable Personal Ceramic Space Heater Electric 220V Fan Forced Blue Red Freeshipping 12$ and less than 800W. (http://www.aliexpress.com/store/product/Mini-Portable-Personal-Ceramic-Space-Heater-Electric-220V-100W-Fan-Forced-Grey-Orange-Freeshipping/605399_683144351.html?s=p)

  The price point makes this a specialty buy for people with low power  prices and low noise requirements. 

I paid 1.93 btc for 1 last night with a small coupon from valkir he may have some more coupons. 

I do think I have made it clear that this is  a costly  miner. You get the quietest and at a clock down to 490-520 gh you get the most efficient.

I am running my 2 at about 895gh  and about .56watts a gh.

Can we stay on the topic plz.

Bicknellski I know you are angry at Avalon and I can understand but philipma and I are not working for them, we use their miner and like them.

Thanks you

Keep us up to date Philip!

Any new pics of the 3 setup?  ;D

No.  Wish I would have bought a couple this winter now I know how quiet they are.  Sure wish the price was more in the $400 range.  Have fun with the new Pi.

waiting on shipment

@philipma1957
If you didn't know, your new Rasp Pi 2 takes a Micro SD card and not the larger one that your old Pi uses.  Just FYI, but I'm sure you know this.  Is the Avalon 4.1 quieter than the S1's were?

thank you I did order 2 micro cards to go with it.

   My third miner is due to arrive today. I will attempt to use it with my other two. I also think if I clock them at about 800gh each for a total of 2.4th
 I can run all three on my evga 1600 p2 plat psu.

This  should use a little bit more then 1250 watts. Run dead quiet. I hope to post some photos later today.

Can wait to see that setup! Im also looking to get more Avalon  ;D

Could you give me your setup for 800gh and around 400watt I guess.

remember I have the plat evga 1600 p2  so my watts will always be very good a little better then the evga 1300 g2

try:

customs

320:300:280

7375

I just set the third one up.  I have 2 silver and 1 black now.  I was doing 1070/2025 = 0.528 w/gh

more settings later

1218 watts/2327 = 0.523 watts per gh. on 340:320:300 for freq  and  7375 for volts

Will do a MM update guide later.

I  would like that very much.

SO hows the progress working out with the avalons? you getting any good ratio with them or in way just more of hobby with them as seem a fair chunk of price to pay for avalon compared to a lot of others out their with much higher hash. Use to love avalon till things changed with  equipment and then sites and distributors

the gear is very good for small in home miners.

3 of them can do 1350watts/2470gh = 0.543 watts per gh  i can go up to 2700gh but i go close to .625 watts a gh.

on down clock i don't know yet that comes next,

one thing for sure 3 on a rasp pi model b full size sdcard model are really stable. and a few back up sdcards are cheap

Not bad going at all good to see you been making good progress and nice simple and effective reports and post made so far. Will be keeping an eye on how things are going maybe go grab some avalons in the future if they come out with some bigger units but are less in cost.

thank you

I just started my first heavy down clock test
of 3 on a rasp pi.

 the three do 1668 at 757 watts =0.453 watts per gh
this is with a hi end evga 1600 p2 1600 watts plat psu.
I do not need to go this low in my clocking but in the summer the ability to drop

from 1350 watts  to 757 watts  and to better watts per gh from 0.54 to 0.45 makes these nice.

 my psu can do 1500 watts as a max with 100 watt safety margin.
It was costly but I do a lot of testing on my dime for the community.

Avalon gave me 1 miner for free
Avalon sold me 1 miner really cheap
Avalon sold me 1 miner with a small discount.

I purchased a few sdcards for my rasp pi
I purchased a second rasp pi for back up
So this thread has some of my cash invested to do  a 3 unit testing this way.

I will be the first to say just a little less money and these are really really good to get.

the three pack was running about 1500 usd shipped to NJ

If you  could get 3 packs at 1200 usd  shipping included. I would say get them.

WITH THE PROMOS AND DISCOUNTS I paid about 850-900 usd for my 3.

I could of just kept the one they gave me  at zero cost, but I did buy 2 more spending the 850 to 900 on those two.

That is because it has a  big clocking range .

757/1668 to 1350/2470 for a three pack is easy
and it goes lower and higher then that range.  that is my tested range


It uses rasp pi so a back up is cheap.

It is really quiet.

Is nice of avalon getting some reduced and free miners of them not bad at all. Nice watt to gh ratio you got on your power down and clock speed to. No doubt am sure their will be sweet factors for Summer and winter times too. Just matter of finding the right ones at right times and making good with it thought out the year. Use to mine massively last eyar and years before but now ratio on mining in UK sucks so sticking to other projects am setting up and working on an maybe in the future if mining and btc goes up again might start to buy some more equipment.

I would need something that gives a nice 10 to 15TH in power and uses next to no energy.

If you want new pi might want to consider the new  ODROID-XU3 Their about $170 but stupidly insane with 8 cores. That is 2 quad core cpus in that too.

 Samsung Exynos5422 Cortex™-A15 2.0Ghz quad core and Cortex™-A7 quad core CPUs

Should save you having to by more Pi's in the future just waiting on the price to maybe come down a little more and have stock in to buy too. videos of them in action and working is some leap ahead for Pi systems.

   that little pc looks like a nice piece of gear.

Philip,

I will test them up to 500:450:430  using an evga 1600p2 both with 240 volts and 120 volts .

I will run 1 hour on each setting doing the 240 volts first.

 First 240volt  test shows 240 volts gives very close to 800 gh it gives    1577/2 = 788.5 gh
 First 120 volt test shows 120 volts gives much less then 800gh it gives  1561/2 = 780.5 gh  
 also watts are 869 not 2 x 419 =838  but I am running a fan and a rasp pi say 10 watts or maybe 15 watts  so 854 vs 838. all in all under 5% from the charts numbers.  remember I am using a very good plat psu.

Been running at

Chip Freq------------Voltage------
420:390:360_______   7625_____

Getting a consistent 950 Gh/s with peaks around 1.1 Th/s and bottoms generally just under 800 Gh/s.  Very pleased just wish they could come down a little on the price!

yeah that slight underclock number works well. I am doing a deeper under clock at

FREQ   325:275:250

VOLTS  7000

I get 1420 for 2 machines and use 720 watts

This would be  710gh and 360 watts for 1 machine

  0.507 watts a gh

I am very happy with sound levels

The sound levels really are amazing.  Even posting about it I don't think most will understand how quiet they are.

I tried a youtube video, but it did not do it justice.   No other miner comes close to it.

I bumped this  so that I can find it. I am going to bump and lock some threads in hardware please bear with it as it will be on the first page for a day extra thanks
