So, Lucko, what's the word on the new set of boards?

Hi,

I have 3 avalon batch 2 with 3 modules each.

Today I managed to buy 3 extra working modules from a broken avalon (modules are working fine).
The plan was to put in every of my 3 avalons an extra module.

I placed a corsair 1000 watt in it and connected all the cables. (power and ide cable)

The avalon boots and works fine however it refuses to hash with the 4th module.

I also tried the other modules and even put a module from my other working avalon in the empty slot.
When I connect the 3th module to the empty 4th slot is does not work either (only 2 units are hashing)

The avalon refuses to work with a module connected to the empty slot.

Can anybody help me?
Do I have to move some jumper/ change a setting?

If you help me to get the 4th module working you get 2 bitcoin as a reward.

I received my Avalon batch 3 w/ 3 blades last week, and here's some of the problems I encountered.

The first set of problems seems to be with power supplies.

The first I tried was an OCZ 600W, obviously underpowered, and mining would stop as soon as I started.

So I bought a second one, a Seasonic Platinum 1000W.
This can power on, but it proved to eventually intermittently die every other time.
When it dies, the WRT703 is still alive, but all the fans would suddenly stop and it would no longer mine.  It always needs a hard power off/power on.
Finally I got it running for a day, but in the middle it died again, and after that it never did manage to power on the blades again, only the WRT 703.
At this point I changed everything, upgraded the firmware, plugged each blade one by one, nothing seems to work.
When I turn on the power it keeps powering the WRT 703 but the fans go on high, and then one second later immediately shuts off - and mining will never be successful.

I changed this to a corsair 800 GS and now it is mining for a week continuously, I even overclocked to 350Mhz.


However, now I have another problem, my miner never goes above the advertised 66Gh/s spec.
Even at 350Mhz it maxes out at 58Gh.

I looked in this forum and saw this is how to find out if my avalon blades are working:

)


It seems I received a unit missing 28% of my hash power
Does anyone have any ideas on what I can do with this?


In summary, here's a list of things I had problems with
- Didn't know how to check to see if blades mine - look at the cgminer stats using "cgminer-api stats" and looking at the [AVA0] section
- power supply connection -
  I suspect the power supply may have shut down by itself if it detects some sort of loop, maybe, is it possible that the high grade PSU shuts itself down when detecting a defective board that drew imbalanced voltages between the avalon blades?   When I changed to a Corsair 800GS, it is a much lower grade power supply than my Seasonic platinum 1000w, and the lower grade power supply works - maybe it doesn't do these checks and powers away anyway, enabling my avalon to mine until now?

Any comments appreciated,

Thanks!

This!

My thought exactly. If Bitcoin is considered money then that will automatically ruin its "decentralized" nature.

Law360, Los Angeles (August 06, 2013, 9:03 PM ET) -- Internet-traded bitcoins are a form of currency subject to federal securities laws, a Texas federal judge ruled Tuesday, refusing to dismiss the U.S. Securities and Exchange Commission's claims accusing the founder of Bitcoin Savings & Trust of running a Ponzi scheme.

Bitcoin is a form of currency because it can be used to purchase goods or services and exchanged for more traditional forms of money, U.S. Magistrate Judge Amos L. Mazzant wrote in a decision Tuesday.

Simply put the psu outside

where is the p5 jumper trying to find this on the wiki right now....
