[Review] Avalon 6 Miner - Winter Mining - Notlist3d - Also FAQ and Help

[pikachuy]

I'll keep the reverse fan for a month and will keep you guys posted if anything happens.

@philipma1957 Regarding the burnt cap, that might be a gray area, because we can't really tell if it was due to heat or over-volting or maybe both, just too much variables. Maybe blockc can do a testing just for good faith, have 1 miner over volted to 12.8 and have another miner run at constant 75-80 degrees at 12.2 volts and see which one dies first.

I would test this myself, but I don't have the funds to spare for the Avalon 6's to test =P

There is really not much reason to ask them to run it.  On over volt you should be within :12V DC ±0.2V .  If you are not warranty is void, so I don't see them supporting over volt to that point.   75-80 should not be a issue it is within Working Environment: 0C to 35C.    

How you mention you don't have funds to spare for Avalon 6 test, I would strongly suggest you don't try things like switching fan orientation.  It chances are voids warranty under: Equipment Tampering And Disassembly.

Thanks for the inputs, but then there won't be any fun of owning one. Or I would of just rent hashes instead. I'm the kind of person that likes to play around with stuff =) even if it voids warranty, makes it more exciting =).

No I can understand I like getting miners and hosting them myself as I can play with them.  I enjoy the tinkering with them.

I was just mentioning it as you said you could not spare funds to test Avalon 6... when in reality switching fan's you are testing .

[philipma1957]

well some good news first the replacement hash board arrives tomorrow.



and now the bad news that same unit running 1 board has stopped registering fan speeds.

and of course as a safety to not over heat the unit won't hash.

the fan speed says 0  and the fan is running full speed.

so I will now need a daughter board as it seems the fan speed detection no longer works.


So once again over-volting can cause your gear to fry.

I will have to contact Yan and get  a replacement daughter board.

I found a reset button on the daughter board and I am now hashing with the one board.

The replacement  comes tomorrow so things are looking up.

Still a great miner.  I have been playing with different pools with it seeing if I could get better then normal or PPS.   Lots of good pools out there, no issues with any so far on pools after using it on multiple.  

At end of day I did not do amazing but was fun trying different pools seeing if I could better then going rate.

NiceHash has been very good recently for "Better than the going rate". I leave all my miners set to go there when the rate is high.  Need every little bit of help you can get these Days, have had as high as .01BTC/TH/Day

Kano.is is the most reliable pool right now

Can anyone give me a quick tutorial on what I need to do in order to get the extra nonce subscription to work on my Avalon 6's?  Is there a setting I am missing? 

I cannot seem to get it to work on Nice Hash.

Thanks!!

You have to put "#xnsub" at the end of pool name. If u done it and it still doesn't work, cgminer on Avalon 6 needs to be recompiled and reinstalled.

Yeah I did fry 1 Avalon 6 by over volting so not messing with that too much anymore.  However, a Little off topic, but since I am short 1 Avalon 6, I do have extra Power Supplies that I can sell to forum members at a good discount.  

They are as follow :
2 x Dell 750W PSU with breakout boards and cables
1 x 1000W HP PSU

Both PSU uses standard 120V connections.

Please P.M if you're interested rather than respond via this thread to keep things on topic.

P.S I mine on nicehash at above certain price, there's no special settings required for Avalon 6.  You configure it the same way as you would for the Antminers.  The password field is where you add the price you want to mine at, example 


password   =     p=.005

Sorry to hear about your loss Nhando.  Honestly anyone out there over volting be careful.   I would not push it over the: 12V DC ±0.2V. - http://www.blockc.co/collections/bitcoin-miners-shop-avalon-blockc-co/products/avalon6-bitcoin-miner 

I have not pushed mine at all on over volting and don't plan on doing it.  Those who have been doing it.... really think about it as it can kill your investment.

What voltage were you at in the UI?  Do you know what it was on a multimeter? 

These reports of overvolting failures have my attention!  I'm about to set up an Avalon6 and I hear the safe threshold is 12.2V in the UI.  I'm just making sure that is accurate and they are not popping even at 12.2V in the UI.  It is scary how little headroom there is between the spec and where these fail.  My plan is to bring mine up to 12.2V in the UI and then back it down just a tad (high end of 12.1-- and only under very controlled climate conditions) unless I start seeing reports of failures within the 12.2V spec.  I plan to drop them back to an undervolt of 11.7V when late spring / early summer hits to reduce heat stress.

[abokhalel2]

Nice Review, Thanks man. I still haven't yet tried any miners from Avalon. I'm planning to try them in the future, but I guess, I need to see their prices a little bit competitive with Bitmain.

In my case the psu was 12.73 volts = wrong 12.4 or 12.5 is okay

The gui was 12.5 = wrong  12.2 is okay

the temp in the room was 92f = close to wrong as max is 95f

This was my older unit. I ran it   Nov 24 to Jan 14    give or take a few days
My other older unit is okay.

Thanks.  I put it on my watchlist.  I knew you were way over.  I'm interested in nhando's readings as well if he has any.

[pikachuy]

Well, after awhile of testing the reverse fan flow, to me it wasn't to my satisfaction, it did keep the temps of the 2nd number and 3rd number lower, but the fan ramp up is too sudden (My main goal is steady noise). Since the fan is flowing reverse and into the ambient temperature sensor causing the 1st number to be higher, it ramps up the fan fast at high RPM to try to lower down the temperatures since it detects the ambient temperature being high when it isn't. As a solution to this, i tried to figure out a way to place the fan on the opposite side so where it pushes air instead of pulling air normally, but the PCIe connections were in the way so couldn't test it out and just let it be and settle for original stock setting.

On a side note, I did multiple testings of the raspberry pi 1 firmware, and from my testing, it seems like the raspberry firmware from 20151111 hashes 100-200 GHS more than the more recent versions. Anyone else noticed the same or is it just me?

They really are a good machine I would not let the few over volting get your attention to much.  Just stay under the 12.2 as said on BlockC's sales site  and you should be good as far as over volting.

For the most part these miners are out there working great.   But if you over volt past recommended... turn it down.

[-droid-]

Yeah oregonmines and Yan at BlockC are great, I had a board die and they were quick to get my unit repaired

[jonnybravo0311]

OK... forgive me if this has been previously asked and answered...

What benefit (besides the web front end) does using the pre-built SD Card image offer?  I mean, if I've already got a Pi with cgminer that has enabled avalon support, couldn't I just plug the avalon into it and fire it up?
