Do you have Teamviewer I can help you fix this

Hello , imhaving a problem with avalon asic 230gh/s . Network is working ok , but there is a red light on and it doenst hash.

It would be a happy coincidence though as mine dropped a bunch as well.
It runs very fast and stable as well.  I have been peaking on BTCGuild with it at 86 gh/s at 350 with sustained at 83 gh/s.
The new firmware rocks.

It's your unit not the firmware.

Any difference you see in HW% with the latest firmware is almost certainly sheer coincidence.

Check what? I dont touched my unit, just flashed the FW .

Check your cables. I am using the the newer firmware on my AVY1's and the HW% is lower than before.

Ty.. This one seems a bit more HW % :S. And today morning i should power off, power on the PSUs to get them hasin`...

It's an avalon Chinese copy, 55nm

1100W PSU

As for the hardware issue Tom_o pointed me in the right direction already...

"1) Fuses blown on those modules (upper left of each submodule on the blade PCB, usually marked "FUSE1" or two fuses right next to each other with a "P" on them - see the btmine thread in Group Buy).
2)  Bad connection on the pits from the blade board atop the blade connecting to the 4 PCBs of 2 worker modules each (the pins could be bent or misaligned).
3)  Power supply marginal, such that only certain modules are getting enough current.

You can check 1) with a voltmeter (some resistance across fuse means it is blown, near-zero resistance means the fuse is fine)
You can check 2) via visual inspection
You can check 3) but putting in a known-to-be-beefier power supply and seeing how it goes

Personally, I'd go with #1, but that's only because that's what I experienced with my own Avalon clone.

Hope this helps!   And good luck!"

I've checked the thread and btmine had posted a picture of the fuse location so thats where I'm going to start...

Ineterested to know if anyone else has managed to fix the possible fuse issue? especially where to get the fuses from.

I'm useless with a soldering iron, tempted just to live with it.

Nothing wrong except 10 chips are not hashing
It is hardware dude not software

What's the hardware issue? I see no fault and are you using an Avy clone or a Avalon 1, or a new 300GH/s Avalon 2?

Thanks for the update, it works great on my old Avys.

Here you go, and given the bugfixes that went into 4.1.0, this might be one of the best firmwares ever, though it's completely untested.

For what hardware??

Avalon1 110nm chip
or
Avalon2 55nm chip

Hello, someone can build the latest openwrt trunk with the lastest cgminer? (4.1.0)

Ty.

Help with a possible hardware issue....

Is there anything I can do? Some sort of visual check perhaps to verify the fault?

Noob I'm afraid, I can find my way around when it comes to software but a soldering iron is way beyond my skills.

You have to stick to CPU and GPU mining if you want to mine LTC. PeerCoin and other atl-coins, I think MaxCoin, work with ASIC mining.

Avalons CAN NOT SCRYPT MINE

they can only mine Sha-256 algorithm based coins

Hello. I'm kinda new to these mining and stuff. I've been using my Gaming GPU for mining and i can't say i'm making good money out of it. And lately i looked for mining products. I've seen products that work on 300-600 GH/s. So what i want to know is;

Can these miners work with scrypt mining programs, can i mine LTC and other altcoins?

After some research i found that most of the Butterfly Lab deliveries don't make it to the buyer so i turned to Avalon ASIC and a product named "Avalon2 – New 2U Size Machine" took my interest. It generates ~300 GH/s if i mine LTC with that the calculation sites say that i would earn approx 1000$/day ( considering these products works with scrypt ). Is that really possible? BTC pools gives 26$/day with that speed

And one more thing i couldn't understand is how does difficulty works. If i buy that machine will the difficulty ramp up because i have higher speeds or does difficulty applies to the general pool not depending on my hardware. Because i read somewhere that scrypt changes difficulty according to your mining speed ( considering these products works with scrypt ) so there won't be people earning too much money.

I don't wanna look like someone who doesn't work for something and just excepts the answers to just drop, because these questions are things i have to search ( and i did maybe not for a big extent ) but i wanna kno some specific things so i can understand what am i doing before going into all of these.

Thanks.

glad i could rebuild some of that faith
