If anybody is interested, our test Avalon4.1 is running fine on NiceHash.com. Here is compiled binary for Linux 64 bit (includes extranonce.subscribe, compiled from our official cgminer fork ): https://www.nicehash.com/download/cgminer-Avalon4-Linux64.zip

If you are using Ubuntu you can simply connect your Avalon4.1 and run cgminer from the above zip file:

sudo ./cgminer -o stratum+tcp://stratum.nicehash.com:3334 -u yourBitcoinAddress -p x --avalon4-automatic-voltage --avalon4-fan 40

(--avalon4-fan is percentage of fan speed)

Here is a screenshot of under-clocked ("avalon4-voltage" : "7000", "avalon4-freq" : "320:310:300") Avalon4.1 running on NiceHash.com:

I have seen many user in this forum including me that dont have the skill or the time to learn using these miners without a controller and go into the time wasting story to test different things and specially drivers usb connection cables etc.(someone will say ok but you learn thrue this)
so how much more will be to be build with a controller inside and all the trimming and tuning to be done with software??? with a single ethernet cable???
they build this kind of excellent hardware and they dont put the controller.
its like selling a car without a wheels...
there must be a reason except cost I believe but can find out what it is..

well I thought about this. If you have a pair of rasp pi's and 2 or 3 sd cards . you will never have down time due to a dead controller.

So if you run 6-10 of these off one rasp pi you have instant backup.

The settings are all software and if you do bad settings just slap in the second card. If you kill off the rasp pi just pull the second one out. So if you want to mine these in bulk the rasp pi is better then a built in controller

downside of these is you want just 1 it will have more wires then an sp20e.

I see your point but unfortunately I cant help you with this setup... you can find some info here for compiling under linux
http://ck.kolivas.org/apps/cgminer/
Use CGMiner 4.9 as it has support for Avalon 4.1 if you compile it with Avalon support flag and once you get it going it would be great if you could let us know how you did it Grin

Hi,

Is it possible to connect Avalon 4.1 directly to PC (Linux) via USB (PC running cgminer with avalon 4.1 drivers only)? If yes, are there some instructions? Or does it absolutely needs dedicated controller?

Yes of course it is possible but a waste of power to use a full size pc when a RPi is $30-40ish, runs Linux and does that job already, not to mention power usage is minimal compared to a dedicated desktop of any sort.

The point is that this miner will sit right next to a PC which is constantly powered on anyway (for other purposes). So how do I connect Avalon4.1 directly to a Linux PC? Do I only run cgminer wih some parameters and it will detect avalon4.1 miner automatically?

I did all of my tests using the TP-Link but am going to get RPi rev B just to have....the newest model of that is a lot better but there is no firmware support for that yet only revision B
I think that there are no other instructions for connecting to a Linux based unit as its already been done in the most efficient manner but that's just my opinion...how many units are you planning to deploy?
I have always been a fan of stand-alone miners but after seeing this interface I want to see how well it can manage more than 1 unit...seems a total waste to have a controller just for 1 miner but then this is geared for multiple unit deployment

Thanks for helping verify the results...its a pleasure to be able to give back to the community and I figured one good turn of winning a miner deserves a good turn of helping others who may have or consider getting Avalon 4.1
I really like this miner the build quality and workmanship are good, it runs quietly for home use considerations...the firmware definitely needs work and tweaking and a price drop would definitely sell more of these but at what loss to the manufacturer....there is no comparison between this miner and any Bitmain product for example night and day not even the same planet from workmanship to materials used

Last off please can we leave chip politics out of this thread this is not a discussion about the past it is about Avalon 4.1 miner lets move on please its 2015

Pretty happy to have you both try all these setup! Thanks you guys

Just sad that Avalon 4 is a little bit expensive!

Valkir Grin

actually if you offered me a choice of the 3 for free I would pick avalon 4.1's now that I found out I can get .55 watts at 850-900 gh then switch to .48 watts at 500gh for free they would be the best choice for me.

Price wise they are just too much if you want a lot of them.

yeah we both got close to .55 watts a gh

i used customs to do fan setting of 15% seems to work .

840 to 900 gh both seem to get .55 watts at 7250 volt setting

I didn't bother messing with the fan as its already so quiet its almost soothing

so the limit for 7250 is around 900GH/s safe to say... I was working my way up from lower voltages until the pool speed matched the miner to get my final results ...its just a matter of what frequencies are used from the looks of it...I guestimated the numbers I used and watched the APC change wattage with each setting but now I need a break from it before I go for turbo mode lol

I got my test data after a longer period and am pretty happy with the results as I hit over my 900GH/s target and don't like to miss Cool

Settings are
400:370:340 7250v and auto volts
Miner starts out using 539W and within 16 or so mins is down to 499W and poolside giving the same results which is important to me as the config page can say 1 thing but reality at the pool can be quite a shocking difference
.5489W/GH works for me 909GH/s @499W
The best part about this speed is how quiet the miner is
I think its quieter than C1 and S3 actually it is the quietest miner I have used with the exception of USB miners Cheesy

My 3 preset settings so far (editing the eco, normal and turbo files for ease of switching modes but customs mode with auto volts does the same thing using those settings:
ECO mode (still needs tweaking but normal is a better deal for more output) :
{
"avalon4-freq" : "340",
"avalon4-voltage" : "6875"
}
gives 431W for around 795GH/s

NORMAL MODE:
{
"avalon4-freq" : "400:370:340",
"avalon4-voltage" : "7250"
}

gives 909GH/s for 499W best bang for the buck

TURBO mode:
{
"avalon4-freq" : "450:390:370",
"avalon4-voltage" : "7750"
}
this gives around 1TH with lowest power usage of 588W

Nice results u got as well phil pretty damn close

Great job man! Grin

800gh for 431 watt! Thats a nice ratio!

Thanks...the error rate seems a bit high but the reported speeds are accurate...can you reproduce my results if you edit the eco file?

I have been doing all custom with the rasp pi.
I based my rasp pi custom settings on the info you gave to me---------------also used a new class 10 plextor card and a new class 10 sandisk card full size not micro in the rasp pi
these custom settings are really good. I will try to ssh this tomorrow

845gh
460 watts

about 0.55 watts a gh

under 1% errors-------------------------------------------------------- this drifts up say .5 % then .8 % then flattens at 1.13 % over 5 hour time period.
sound meter 39-42db
fan 900 to 1240 rpm with 15% setting
temps under 44c

Im testing 900GH/s right now my settings are as follows:
400:370:340

~~using 7125v Im getting 519W and it drops to 499W but poolside is not reporting the same rate...still tweaking~~
upped the voltage to 7250 and 400:370:340 let this run for the next day

What I did instead of swap SD cards as Im not using RPi (I might go pick 1 up for fun today) is just edit the 3 files in the config directory (eco normal and turbo files) ...my eco is 340/6875, normal I have my current test settings, and for turbo I use the default clocks for 1TH with .7750 to make switching easy, and then just use CUSTOMS for quick dirty tests

'The right to privacy matters'

going to try to make my eco the same as yours. for now I have been doing this setting in custom

I get about 909 gh at 557 watts = 0.61 watts per gh

macgyver gets 800 gh at 431 watts = 0.54 watts per gh

After much testing and tweaking I have come up with my own ECO setting which is:
{
"avalon4-freq" : "340",
"avalon4-voltage" : "6875"
}
This gives around 800GH/s at a steady 431 watts at the miner and poolside...not too bad lets see if it can be reproduced (should be no problem) Cool

What I did was edit the eco file so its permanent and 1 click efficiency...results are:

Next step is to see what it can do at 900GH/s then fine tune around 1TH/s or higher depending on efficiency...
I love how quiet this miner is!

One thing to note...voltage steppings are in .125v increments so my previous setting of 7800 was not actually using 7800 but .7750v so (sorry no documentation anywhere on this)

6875
7000
7125
7250
7375
7500
7625
7750 are the voltages I am still playing with...more results to follow

Excellent review with good pictures - well done!

I can't see me getting one tbh, but this will help many people out with their decisions I'm sure.

It's unfortunate that you have also been the victim of poop-dawg spamming in your original thread, it's a sad day when forum members wishing to inform & guide each other have to resort to a self moderated thread to avoid the splatter of his shit all over the place. Keep up the good work & I look forward to seeing some more reviews

PS: Love the no-pooping sign - I think it should become the standard image for anyone who wishes to avoid his rancid, smelly messes Wink

Free is good... would you (macgyver007) recommend this unit over SP20 / S5s? Why or why not?

---

More people need to do moderated threads and pooper scooper dogie out of them. That make this section of the forum much cleaner.

Edit: Nevermind, missed that this was the one from ck's giveaway.
