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,

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.

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.

NO

350Mhz x 320 chips = 112GH/S

120GH/s / 320 chips = 375 Mhz

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.

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

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,

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 !!!

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

You should find lines that say

[match_work_count]

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.

350 mhz pulls 970 Watt on my unit.

Sooner or later its gonna kill your 1000W unit. They are not built for  this permanent usage.

you can do the same with 1000W

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

Enjoy 110 ghash

for a 4 modules you need psu 1000w

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

What am I doing wrong?

It's not a resistor it's a magnetic bead actually its an inductor.

Hey. In the spec file to the FPGA (BOM file) is the resistor value as "MB". What does this mean? Someone knows?

I am looking for 1 or 2 broken Avalon modules.
If you have a failed module that you haven't been able to get working I might be interested in buying.

I was expecting it to need some messing once I saw the red light so pleasantly suprised it's back up, good to know it's not a big problem if it completely fails.

My experience has been that once a red light happens it will soon happen again and one module will have a bad section that needs to be disabled to get the rest of that module to work again.

Hope thats not the case with yours but fixing it isn't that hard and you'll only lose about 4GH.

It's a sad day, after 126 days uptime on my batch #3 I finally had to reboot it

It stopped hashing, all the readings were 0, all the match_work_counts were 0

Tried rebooting twice through the web interface but no joy, went down to where its hosted to find a red light on, turned the PSU off and back on and it's back up and running again
