Avalon ASIC users thread

[ProfMac]

So I have my 4-module hashing happily at ~75Gh/s with the stock 750w psu and using the max clock settings in cgminer for my power. The Avalon Wiki says that I should bet getting :

Hashrate：90GH/s, Chip:282MHz, 750W
https://en.bitcoin.it/wiki/Avalon

What am I doing wrong?

Check the WEB page under the system ---> "cgminer API log"

You should find lines that say

[match_work_count<n>]

from 1 to 32.  These should all have similar numbers.
If you have fewer than 32 workers, go to the configuration tab and change the number.  Typically, there are 8 workers for each module in the Avalon (8, 16, 24, 32).

If there are 32, but one of the numbers is very low, you have a under-performing chip.

I agree with the recommendation of the OCZ 1250 power supply.  My power draw dropped by about 30W after I changed to the power supply as measured by a kill-a-watt meter.  I also think the unit is more stable, but I don't have data at hand to back that up, it's just gut feel.

You may want to update to the latest c kolivas firmware and use the --avalon-auto option.

i use 3 power supply 1000w in all my 4 modules. only one with corsair 1200w. (4 avalons 4 modules for me)

all work fine since some month now and all warranty for 3 years if need !!!

How much do you think I can get for a B1 4 module Avalon that has an 860 PSU, it will do 107GH/s if I wanted to sell it locally?

Thanks,

FYI, those OCZ PSU's might be a little harder to get since OCZ filed for bankruptcy a couple of months ago.

Buy a 1250 OCZ psu and change chip to 350 mhz.

Enjoy 110 ghash

I have an Corsair AX860i, at 350Mhz my Avy does 107GH/s. I would think with a 1250 PSU you should be able to get more like 120GH/s.

NO

350Mhz x 320 chips = 112GH/S

120GH/s / 320 chips = 375 Mhz

120GH/s / 320 chips = 375 Mhz

At 350Mhz x 320 chips (on either my B1 or B2 Avy) I get 107GH/s
at 340Mhz I get 104GH/s

I won't do 375Mhz as my PSU's and or Avy likely won't survive it.

Hi all

I've posted the first firmware officially designed for avalon series 2 (55nm), but with compatibility for series 1 devices.

http://ck.kolivas.org/apps/cgminer/avalon/20131229/

This is based on an updated cgminer 3.9.0 and has been running flawlessly on the series 2 device I've received. This firmware should work fine on 110nm technology devices too, however the configuration syntax has changed so you may find that you'll need to do a reset configuration after flashing it. For older devices there may be slight improvements in stability and better support for mining to a stratum proxy

EDIT: Note I said SERIES 2, not BATCH 2.
EDIT2: Resetting ALL the settings means you will need to reconfigure your network from scratch with a lan cable.

I just updated to to this firmware blowing away my batch 2 settings and once I go it up and running I noticed the applying changes just spins and spins it doesn't update like in the previous firmware. I have to close my browser and re-open it to see the changes have been made.

The 2nd issue is, I accidently gave me Avy2 the same IP of my Avy1, so I unplugged the Avy from the LAN and connected to the Avy2, when I changed the IP (the updating settings kept spining) and closed my browser and reconnected to the Avy2 on the new IP the update settings process has wiped out all my previous settings including my pools, etc! SIGH

The issue with this is that the applying updates never applied the updates to miner fully. After waiting a couple of minutes when applying them the first time and waiting then giving up, the settings show up in the configuration but when you look at the status it shows the old settings. When I hit apply again it finally updated the settings correctly and at it's normal pace too.

I miss the flashing light while hashing, unless that doesn't normally work on B2 Avy's? It works on my B1 and my mini using the 0821 OS which worked when I below the settings on both Avy's I never blew away the settings on my B2 so it's second light never flashed while hashing.

Pros:

I do like the nearly real-time HW% updating which shows in the Status and of course the logs.


Thanks,

I wonder did you even test your own firmware before releasing it?  

Thanks,

Pretty clear in my post. Also clear that you may have to reset all your settings, no?

Resetting ALL the settings means back to the original static IP needing an ethernet connection.

Really I did not know that!! LOL

Of course I blew away my settings, that's what I normally do when update firmwares on my Avy's. So yes silly me forgot to mention that I blew away my settings.

Just updated my batch 1 Avy, resetting all settings and reconfigured it. After reconfiguration minus the "--avalon-fan 65" from the extra command field the firmware was leaving the fans running at 720RPM while hashing at 340Mhz, before my Avy melted down I added the "--avalon-fan 65" command back. Phew!

Avy question,

looking at my B1's log I noticed that one of the boards isn't working, so I don't know really if it worked from the start or it something failed on it, I haven't taken it part but I have sniffed the back end to see if anything smells burnt and it doesn't.

The one that is failed is; [match_work_count29] => 0; which would be on my 4th module; the one I bought from Avalon-Asic a few months ago. I would like to know with the module facing you (components facing you) which side do I start counting from to find board #29 if I don't see anything burnt?

Thanks,

It's the end of the year, and people may want to buy or sell their Avalons now.  I have posted a blockchain flea-market thread.  You can offer an avalon for sale, or make a bid on an avalon.

The question is what is a good price to get on Avalon 4 module rigs? Is 20$ GH/s too low?

The question is what is a good price to get on Avalon 4 module rigs? Is 20$ GH/s too low?

Yes, that is a good question.  We all would like to have an answer.  This number depends on why you mine, what your heat, internet, security, and electricity cost, and whether you are paying interest on credit card or other debt.

To estimate this number, I used this calculator to estimate the total BTC earnings at my electric rate.

Code:

0.4576 (total BTC during mining lifetime) / 27.333 (GH/s) * 735 $/BTC  ---> $12.30 / GH/s  (based on btc-e, overclocked to about 360 MHz, approximate historical data from eligius)

Offer it at my auction for 3 module units.  I will pay 1/4 of the successful amount for your 4th module.  My destination zip is 56267, to discuss shipping of the 4th module.
Is this a batch #1 or #2; or a batch #3 style module?  I am interested in any of them.

I have the following, batch1, batch2, and mini. But I would like to get rid of the batch1 first, it has 4 modules and an ax860i PSU.

Someone locally offered my $20 GH/s or $2200 for the rig, I am not sure if it's worth selling it for that price or if I should try to get more for it?

That is BTC 2.99 at the current exchange rate.  The calculator I quoted gives BTC 1.72882 before the electricity costs more than the mining proceeds.  My thoughts are that it is a good offer and it exists now.  Perhaps your Batch #2 would be a candidate for my auction.

Back this summer when I bought my 4th module for my Avy B1 I noticed that there was a lot of silicon on one of the boards, it looks like someones fingers were covered in silicon paste and got it all over the chips. Could this stop the board from operating?

Yifu said it wouldn't affect the board...

Thanks,

I think they used non conductive thermal paste so I don't think that would be the problem.
Do you have an entire module that is not working or just one of the 10 chip PCB's not working?
