  So these are scams?

I'm  watching one auction (not one of the ones I linked) and it is a 3 module device. I just couldn't see how the numbers could add up so I asked a question. He claimed it was using 2nd Gen chips but how can you possibly get an even number like 200 out of three cards ?!?! Also I wasn't aware of Avalon putting 2nd Gen chips in their older devices.

scam or not, they are not worth $10k.
gen 2, they only did 2-3 units put into avalon mini's to showcase their designs working.. These were both sold into china and later put on auction, their official reseller got one and auctioned it lateR:
http://avalon.btcfans.com/ (avalon mini design with g2 hashes at 140GH, 2 boards). So theoretically, if they somehow put gen2 chips in avalon units, it would be around 200+gh..

check all picture and see alot HW errors

accepted 1000
HW 11000

frequency 1300

temp3  -xx

i never buy this unit with 5 or 6 % HW errors or more

You're doing it wrong.

And you're calculating %HW wrong.

[ste0024]

I've done any calculations but when I see my personal statistic and those ebay

me

Accepted  82000
HW 35964
[Device Hardware%] => 0.6737

on ebay

Accepted  1000
HW 11000
[Device Hardware%] =>ALOT FOR SURE

ONLY 1000 Accepted FOR 11000HW is a very bad result

Avalon sold a few Prototype devices..... looked like the avalon mini 60ghs....  but it had the 2nd gen chips... was supposed to be 200ghs..

[Tasweb]

Thanks xzempt.

I'm pretty sure I dodged a scam. The guy pulled the auction at the last minute, re listed it and then pulled it again.

Hello,

I've just acquired my first handy, dandy Avalon ASIC machine and I'm having problems getting it to connect to stratum.btcguild.com on port 3334.  I can ssh to the machine from any of my RFC 1918 subnets successfully.  I can use the web interface *IF* I'm on the *SAME* subnet as the Avalon.  Thus I feel certain the network is working as it is supposed to.  The problem comes when I configure cgminer to use one of my workers at stratum.btcguild.com:3333.  It won't connect and btcguild sees no mining activity.  It's odd because while in an ssh session if I try to "telnet stratum.btcguild.com 3333" FROM the Avalon box I get no connection *BUT* if I try "telnet "telnet stratum.triplemining.com 3334" FROM the Avalon box I get a telnet connection to port 3334 successfully.  I have other mining devices on the same subnet as the Avalon machine that *CAN* connect to stratum+tcp://stratum.btcguild.com:3333 so I feel certain this is not a firewall device between the subnet and btcguild causing the problem.  For reference here's the Avalon's /etc/config/cgminer file contents ->

config cgminer 'default'
        option miner_count '24'
        option api_allow 'W:127.0.0.1'
        option pool_balance '  '
        option chip_frequency '344'
        option pool1user 'GuildPoolUser'
        option pool1pw 'GuildPoolPassword'
        option pool1url 'stratum+tcp://stratum.btcguild.com:3333'

This kinda seems like the Avalon itself is not allowing connections to port 3334 at stratum.btcguild.com BUT I cannot find anywhere that port 3333 gets dropped.  What gives?  Many thanks for your help in advance.

Ahhhh .... figured it out.  Someone cleverly set the DG to 192.169.x.x INSTEAD OF 192.168.x.x.  V-E-R-Y sneaky of them

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

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.

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.

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.

[Furious]

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

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

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?

for a 4 modules you need psu 1000w

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

Enjoy 110 ghash

you can do the same with 1000W

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.
