That looks like a crudely ground bare spot down the middle of the board, looks a quick fix for some problem with that revision of the board (version 1.57).  I got a version 1.8, it has no line ground down the middle..

Sorry, I know I asked this before, but if we change the drivers to WinUSB to run it with cgminer on a computer, then get a replacement TPlink, can we just plug the USB cable into the new TPlink and be good to go? Or do we have to change the drivers back again

So do you think a single 1200 will work for these units. I also plan on adding a knob that I can control the fan manually. Let me know what you think I already have a design that I might try to create tomorrow.

I do not think a single 1200 would work for this, just on power alone.  Then there's the complication of both sides needing the 24-pin PSU connector (though you could get a splitter for that).  I'm thinking a good, solid 1350 could do it.  But these are just guesses.  If you're like me and have a MicroCenter in the area, they have a great return policy both for unneeded and nonworking results.  So far I've given them back 2 CoolMax 1000ZUs and 2 SolidGear 750 Neutrons. 

I was thinking that you just need a splitter. To run so you can power the 2 blades. Would just need one side. The signals are done by the avalon control unit. If there is enough juice to go around you would just use that. Split the lines that is powering the two blades. That's all you really need right? What does the CPU pins really do for the miner other then send it power?

can you post a pic?

After 3 hours of messing with my new avalon I got it hashing with the functional modules   looks like 3 modules where damaged in shipping ill have to take them apart tomorrow and see if I can fix any of them. I am currently hashing at about 170gh with no fan issues with two corsair 750w CX modular power supply's currently on sale for $79.99 at newegg if you buy them before midnight they also come with a $20 mail in rebate making the final price on them $59.99.

Back on my fan pb, I can't force a RPM. It keep going up and down idk why. I set temp target to 50, it's now 52° and fan are decreasing speed.

raaaaaah

Some numbers seems to be reversed. Try higher target instead of lower.

It's like i can't force cgminer to a fix % fan. I set the temp target at 60 but same problem, it starts hashing with fans at 2600rpm, with --avalon-fan 50 and go down to 2150 and 2060 and 1980 etc etc etc, then stop.

and now its stopped

I was able to fix the fan problem slavo by unpluging the 2nd temp sensor now I am able to keep the fans at any speed with out them turning off like they did before.

[Professoruss]

Wow. All these horror stories.
I luckily ended up with PSUs yet didn't order any. (I'll send someone a couple if they need them once replaced. Get me a shipping label)(no smoke yet)

Both units work.

On the downside, my second unit had both cards unscrewed and rattling around.
The screws were in the box, mounted them, powered on and hashing. Currently one is powered off because I don't trust the PSUs.

The other downside. How much power they use. Not a complaint, I knew it getting into it.

[grumpy619]

How much for you to ship them and are you in the US?

[sacskate]

I had my unit hashing fine from yesterday until today. I ran cat5 to my garage to run this unit and moved it out there. Now It just sits and keeps saying this over and over. Any help?

Thanks for the link!

Hello Guys, i received my Miner today no problem connecting it to the computer via ethernet, the antena for the wifi didn´t arrive i wouldn´t need it either

First impression was it was behaving strange, the hashrate keep bouncing up and down 20 to 200 then 200 to 20 in cycles. So i decided to open it and dismantle for check everything, and i found some correctors misplaced almost about to break, fixed that connectors and went testing it again and voilá 220G hashing power with no cicles I had to put the fans on 20 because this thing makes a lot of noise, anyone can help on this matter?? Some different fans??

I´m using so far stock PSU´s i may change them later i really don´t trust this ones, beside i won´t overclock my units because i think it´s a great risk with all this money invested

Anyway seems i was a bit lucky my miner wasn´t so damaged like others so i´m happy with my purchase so far, although it makes a lot of noise  

[mchu168]

My miners that I ordered on the 7th finally arrived today  It was stuck in Shipment Information Received limbo for 3-4 days before it started moving fast.  

I am happy to report that the included power supplies worked fine on 120V for me.  Each miner is pulling about 8-9 Amps across 120V.  

However like many others there were various minor issues.  I ordered 4 and I think all 4 boxes had loose screws rattling around.  Only 1 of the 4 had both blades still attached.  2 had 1 blade completely loose and 1 had only 1 screw left.  And only 2 of them came with antenna's, though I would not run them wireless even if I could so I do not care.  

I had 1 bank of 16 on a miner reporting 0 in the status.  It turned out to be the connector on the board itself, the one of the sockets pushed out.  Something others may want to watch for.

I also have 3 banks across the miners that are running at only half the speed of the others.  Not quite sure why yet.  I touched up various solder joints on the backplane but that did nothing and I do not see any shorts.  

Overall though they are performing pretty well.  Once I solve the problem with those 3 banks I will be happy.

I've been busy learning how to do smd rework and make solder bridges.  Managed to get several "dead" modules hashing again but have also discovered some half speed modules.  I'm probably useless at debugging this issue but would love to hear if you get to the bottom of it. As some opined earlier, a logical explanation is another fuse somewhere on the top of the board protecting half the module, but I guess that would be too easy.... 

[Powell]

I've fought the fuse problem to many times already...  I have 3 modules that run at half speed and so many little things...  I have had them apart enough times I may be able to take them apart and put them back together.

I have one unit running one of the Syscool Avalon Watercooling kits but it's got an entire board that died...  Popped fuse and apparently my solder contacted wrong and it blew up so until I can figure out a solution to cut that module away from the good one I'm down 2 modules on it.  The kit is a closed loop system and for the most part very nice (although I have replaced every fan with Antec/Corsair versions) and kills the noise.  I bought 7 (and 7 extra cards because I was going to do 3 modules per box) but so far only have 1 installed.  With all of the little issues I really don't know if Im going to install the rest.

Tips for the screws, use the same style screws as your power supplies (I can't think of the size).  Replace them all and the case will be rock solid.

If anyone figures out the half power modules I am down to try the fix. 

[Professoruss]

How much for you to ship them and are you in the US?

send shipping label, you can have them once the new ones come in.

Hello all,

for the ones who just received their tracking number, could you please provide feedback and give status here?

I already received my tracking number yesterday but the status is still  :

Wednesday, January 22, 2014    Location    Time    
1    Shipment information received    HONG KONG - HONG KONG    09:15    
 

What template of your number?  My number is EE*********CN ems. I can't track it at all sites although received it yesterday.

I was able to fix the fan problem slavo by unpluging the 2nd temp sensor now I am able to keep the fans at any speed with out them turning off like they did before.

That did the trick. But isnt this dangerous ? No overheat protection ? I have temp1 at 21° where does that come from as i have only one sensor...

That looks like a crudely ground bare spot down the middle of the board, looks a quick fix for some problem with that revision of the board (version 1.57).  I got a version 1.8, it has no line ground down the middle..

The ground line down the middle is just a crude make-do solution to provide separate power to the two blades.  I'm thinking they did it that way to use the parts available at the time.  Mine also has a ground line down the middle (though a different configuration), and it works fine.

[twib2]

So do you think a single 1200 will work for these units. I also plan on adding a knob that I can control the fan manually. Let me know what you think I already have a design that I might try to create tomorrow.

What does the CPU pins really do for the miner other then send it power?

Splitter should do it.  Someone else posted that both sides need the 24-bin PSU connector so you can't just get away with fully populating the PCIe and EPS connectors of the 2nd card and it must have a 24-pin also.  But, if the PSU is beefy enough, a 24-pin splitter should work just fine - there's really no way for the boards to know the difference if the power's there in enough abundance.

[stewdk]

One of my BTmine units went offline late last night.  Fans were off, PSU fans were also off, and the LED from the fpga board was solid red.  Could still access the tp-link interface.  Tried different PSUs, nothing changed.  After some poking around with a multimeter, it turns out that I definitely have a short between 12V and GND on one of the blades/modules.  I unplugged the faulty module and I'm back up and running with only one module for now.

[mtnminer]

Update on my orders, I am in the U.S. I paid for all with bitcoin

My order on the 10th of two units was "Shipping Information Received DHL" 1/21/2014
No new information this morning?

My order on the 14th of three units was "Shipping Information Received DHL" 1/23/2014
                                                      "Picked up DHL" 1/23/2014

So my last order is on the move before my first order is showing on the move?  It does not
make sense, but I will be glad to get all five units here very soon, unpack, trouble shoot,
repair and get to hashing!

Thank you all for the great information you are sharing, together we will solve all these issues
and be hashing successful.  I hope future orders any of us make with China/Hong Kong will
be with a group that produces a high quality product, with fewer problems out the dock door.

I still believe these where a good deal, as I still would not have had my 1 th/s unit form Bitmine
in Sweden yet and it is at this point it would have been delayed until at least March anyway!!!!

I am relieved, I am free of the BITmine Sweden deal and getting my multiple Chinese units instead.
Yes, the will take up more space and burn more power.  But, I am  ahead of the game by hashing above
1 th/s 60 days or sooner than I would have been and that makes a big difference on complexity and
return.
