[Work in progess] Burnins Avalon Chip to mining board service

[Schrankwand]

My two boards are now up and running via two USB cables. I am kind of confused though, since one of the boards makes a "clicking" sound when not yet warm. It also shows, although it has almost same rate of accepted shares, a very high number of hardware errors. I am trying to run them at 450 though.

Ticking timebomb ?

Better lower the frequency, and what are your command line settings ?

Burnin,

You have 240 of my chips from Zefir batch 3, which still shows up as 'Processing'. I emailed you several times and gave me vague responses as to when my boards would be assembled. I would like to have my order refunded and my 240 chips shipped to me ASAP, because unfortunately you cannot hold your timeline. I understand the Avalon debacle screwed you over, but now you are screwing those of us with incomplete orders. My patience has dried up, I placed an order on 7/31 and no updates to it since then. I applaud your efforts and congrats to everyone who got their units, but at this rate, I will not accept assembly that is already a month behind and already 3-month behind schedule. Thanks for trying at least.

Not speaking for burnin but i believe all ordered boards already were built. He now ships the miners as soon as they reach him from the assembler, after the assembler tested the unit.

I have spoken with burnin (finally). He is just going to ship my chips back to me. I thought one of my orders was in the assembly queue (the other was converted to a Bitfury discount), but due to Paypal freezing his account, the payment for my 2nd order never went through. My apologies for the confusion. As much as I hate Paypal, I preferred to have some recourse in case shit hits the fan (eg. Terrahash). Granted, I used one of my orders towards a Bitfury discount, I still had to pay more out of pocket to get anything shipped (Avalon's fault, not burnins). Either way, he is true to his word, but I would suggest he hire someone to handle his correspondence if he has to dedicate all of his time to assembly, etc.

Boards are running stable with 413 now, no clicking. Boards were set with

--avalon-options 115200:2:10:28:450 --avalon-auto --queue 4 --bitburner-voltage 1285

And are running fine with the auto option now.

I tried with this settings also but it seems as one board always gives up... it idles around and sometime two other boards are following.
one seems to be running without problems.

the first one that defaults is running at 59°C @ 400 mh/s per chip, the other ones are around 55/56 °C.
Overclocked to more than 400 mh/s they go up beyond 60 °C before they idle.

Have you thought of the temperature that the boards are idled ?

I have this:
--queue 4 --avalon-options 115200:16:10:d:400 --bitburner-voltage 1250 --avalon-temp 50 --avalon-cutoff 65 --avalon-fan 100

I explicitly set the cut-off temp to 65. The default is 60, so that's probably why your boards are idling.

What is the maximum number we are talking about for temperature?

I have now a rate of 397 and 385, which is not enough if I want to reach ROI somewhere before July lol.

You'll have to delve into the specs of the Avalon chip, but this might help:
On https://en.bitcoin.it/wiki/Avalon#How_to_Compile_Your_Own_Firmware_for_Avalon :

New  Batch3 Machine: Target Temperature to 70℃ and Overheat Cut Off Temperature to 90℃

Depending on the design of Burnin (on other words how accurate is the value of the temp sensor), you can go up in temp...

BenTuras, thank you. You made my day!

I thought my cgminer (3.3.x included in minepeon, latest version) is the problem, because I doesn't support overvolting above 1310mv, but the main limit in reaching more than 400 mh/s was the temp limit. They are running at about 425 mh/s now at 62°C with the foloowing settings:

Code:

    "avalon-options": "115200:2:10:30:425",
    "bitburner-voltage": "1300",
    "avalon-cutoff": "68",
    "avalon-temp": "30",
    "avalon-fan": "100",

What are the bitburner XX "standard" Avalon and voltage settings for cgminer without overclocking?

Interesting!

Mine now run welll at 55 and 57 degrees at a stellar 450mh/s. One of the boards is throwing HW errors at me like crazy, but it is still at around 8.2gh/s while the other knocks out around 9gh/s. Awesome.

[FlappySocks]

Hey burnin,

Are you still planning to refund me? My emails don't seem to reach you, and I don't see anyone else talking about refunds so I thought I'd bring it up right here. I paid you 30~BTC, and all my chips are refunded. Let's talk. I'm sick of waiting.
 

I'm waiting for a refund too. Willing to put it towards a BitFury board if it can make ROI.

[slastar]

I have problem with 1 of my BitBurnerXX. When stacked and connected by BUS-CAN it's mining normal, but when conected direct by USB Windows doesn't detected it at all. WTF??

[solari]

455MHz @ 32C?   Are you running them in your fridge???
Anyway I'll try with my air cooled bitburners and "--avalon-auto". Let's see what happens...

For me "--avalon-auto" results in slower hashrates - after about 10h it went down to ~320MHz (starting at 380MHz). I'll try again with v3.4.3, maybe this will result in better rates...

I would really like to see pictures of solaris setup, must look awesome.

sorry for the delay. I had problems with my PC.
At the moment it´s cold outside ( 4°C) and I set the voltage to 1300 mV.



I´m using an old cooler from a car. It needs 150 W for the ventilation.




And this is the water pump. max 2200 l/h



And this are my 48 bitburnerXX:








All the things are working very good with no problems.
There is only one problem: It will take about 4 weeks. Then the energy costs will be higher than the earnings.

Maybe you can use the waste heat for house heating then? Put the radiator inside the house etc.

[smoothrunnings]

There is something wrong with the math.

I am guessing that 5GH/s units are the 20 chips modules. If I convert 105 EURO's to CAD it's about $150 CAD. To get over 100GH/s I will need to spend $3000 CAD. Yet our friend YiFU sells the 4 module Avalon's for 12BTC which is $2400 CAD which I can easily get 100GH/s from.

Don´t forget the time in the math.

The costs for 16 Bitburnerxx ( with together 320 chips) were ( long times ago)
320 chips 0,086 Bitcoins each : 27,52 Bitcoins
16 BitburnersXX 105 Euros each: 1680 Euros ( it that times about 16,8 Bitcoins)
ATX PowerSupply, Raspberry Pi,..  250 Euros  ( 2,5 Bitcoins)

27,5+16,8+2,5  =  46,8 Bitcoins



Today the AVALON 4-module miner with 320 chips costs   8 Bitcoins

So today it is better to buy a miner with 320 chips for 8 Bitcoins then for 47 Bitcoins ....

WTF?

Lets do some math, maybe im just going nuts here.

150 watts for the ventilator

XX Watts for the pump, you didnt write about that.

around 110 watts per bitburner board, coming up to around 5300 watts
This means, we are talking 5500 watts and a hashrate of 420gh/s.

"calculating"

My calc is that you need around 3900 kw/h per month. Basically, this equipment burns on the level of a normal family per month.

How expensive is that? Well, in my country, I pay around  25 eurocents per kw/h. Coming up to 975€. That us quite expensive already.
Your mining profits right now, per month, are around 3200 USD, around 2400€. Don't want to be annoying, but the difficulty would have to double again, to get you trouble. Not that it cannot happen, and it WILL likely happen, but how far do you think this is gonna go? At least you won't loose profits in the next four weeks I guess. You could even take doubling the diff right now to be profitable...

If the difficulty rises 40% this time ( 5 days)  and next time ( 5+ 10 = 15 days) then it´s 96% highter than today. In this case the 4 weeks are only 15 days....
And yes, if I could make the decision again to buy or not to buy the chips and bitburners months ago with the knowledge of today, I wouldn´t have them.
