Avalon ASIC users thread

[opentoe]

Could somebody tell me how much bandwidth an Avalon consumes in KB/s? My connection is 800 KB/s down and 100 KB/s up, but is also needed for browsing, downloading etc.

Jesus, where do you live?

In a third world country, like italy. I have the same connection (well, i have 3 of that connections, bounded togheter to have something somewhat usable).

The stratum protocol should use something like 1Kbps or 1KBps, not sure.

Italy? Then how does the Pope do his online banking?

Nailed the root cause of my problem: it's a Control Unit. When swapped for a CU board from another Avalon, it started mining normally.

Now, since one of the CUs is dead, I need to check out 4-module configuration. Anyone using 4-module setup currently?
Any advice - what PSU is needed, do I need to change some jumpers on control or power board or something?

I think you need a 1000 watt PSU with 4 modules (on the wiki it says 750 watt but in the confirmed working list a 1000 watt), it has one confirmed working on the list https://en.bitcoin.it/wiki/Avalon#Comfirmed_working_PSU_list but others may (or may not) work also

in the webgui you have to select the number of modules, (maybe someone else can fill in, bitcoinfoundation has a 4 module unit, dont know what PSU they have tho, maybe the Enermax)

Maybe better to have a bit too much power than too less. I have Corsair Professional Series Gold AX1200 PSU for Avalon, but can´t confirm yet it works as Im still waiting for Avalon Batch3 four mod unit.

[Matthew N. Wright]

Wait, so the PSU everyone is getting with the 4 module units in Batch 3 won't be strong enough to power it? Why would they offer it then?

[xiangfu]

Hi spiccioli

Add other cgminer options (like --fix-protocol) to /etc/init.d/cgminer is right. I plan to add [Cgminer options] to the web page in next firmware. then we can add the 4th pool or 5th pool at [Cgminer options].

Xiangfu

Hi xiangfu,

I've just updated my units, but I still cannot mine on p2pool without using --fix-protocol which has to be added by hand to /etc/init.d/cgminer

Is this the way it is supposed to be? Shouldn't p2pool mining be working with stratum when using latest cgminer?

Looks like this guy missed the option: order without PSU. Well spent money though.

Edit: If not happy, you can ship the extra module to me in China - I give you BTC after I get it in safe condition, or we can arrange a meeting in Korea next month.

I saw the option and ordered with PSU. The question is, why would that PSU not be sufficient?

xiangfu,

thanks for confirming, but what's stopping cgminer inside avalon from using stratum with p2pool?

I have several cairnsmore boards mining on p2pool with stratum with cgminer 2.10.5, so a much older version than the one inside latest avalon firmware.

is this a problem of p2pool code or one of the version of cgminer inside avalon?

p2pool's stratum code. The version of cgminer inside avalon in the latest firmware is up to date now.

here you can see 10 cairnsmore1 mining on p2pool with stratum and all is running fine.

cgminer is also older than the one on latest avalon firmware.

But if I point my Avalon to my p2pool without adding --fix-protocol I only get invalids.

How can it be?

I heard you the first time. Dunno, but the rest of the pools get it right yet it makes the avalon spit out heaps of dupes. I don't understand python so I wasn't about to go poking into the p2pool code. If/when I have more time on the avalons I can investigate further to see what p2pool is spitting out that it doesn't like, but for now, the code used by the cgminer on avalons is the same as the current cgminer code and not a single pool has a problem with them. I have some vague ideas but nothing conclusive... and have other tasks taking priority for obvious reasons.

nearly every day Avalon stops for a long time; - if I can see something I see

Code:

Socket connect failed: Connection refused
[Firmware Version] => 20130419
cgminer-8e8313c
luci-28b4ff2
cgminer-openwrt-packages-f2bc5dc
[USB-Serial] => /dev/ttyUSB0

where to look for the issue?
TIA

[server]

I had the same issue. Today for the first time.

Reflashed it to the previous firmware 20130410 and now it's hashing again.

Unit struggled before it went down.

[ewibit]

notable is that no restart or stop/start of cgminer aided and today a cold reboot of Avalon neither...
only a cold reboot of Avalon AND the router (TL-MR3420 with latest firmware)

[server]

I'm running smooth and steady after changing router & isp/uplink-provider.

Cgminer NMW (no_matching_work) was high too so I think there was something wrong with the connection.

But back on track again

You can try what I did, check your connection to the pool or try another pool.

Maybe pull the plug from your router for 10 seconds ?
Also I changed from wired to wifi and I flashed back to 20130410.

I think my unit did not perform well because of a bad connection, either on my side or the pool's side.

I am on more then one pool and at all was the same (with Avalon; - 1 GPU stays connected)





as you correctly said, I have had to cold reboot the router too (connected with wifi)...
