There is a problem with this "ypool.net"

Before the maintenance, I had over 20 maxcoins "unconfirmed" and 1.89 in my balance.   After the "maintenance" I have 0 unconfirmed and my balance is magically stuck at 1.89.

The minimum  payout is at 5.  This smells like scam.  Maybe it is just a glitch due to the volume, but where are the unconfirmed coins?

Just be careful guys...This pool will not pay you anything the way it works now.

You are right, I got all of them above 31 GH/s, some do 34 GH/s.  Thanks for your help.

I've noticed similar behavior with my mini rig, it does not like ambient temperature to fall below 15C.  Just won't start.

Here are some pics of my chilies.  I used 6x32 1 1/2" bolts from Home Depot, Arctic Cooling MX-4 paste, some old PCB for backplate material.
I just hope I will not have to restart it every day :-)

Hairdryer worked for me (for 4 cards, need to get a fan connectors for the other two), but I had to do it slightly differently.

1. power cycle the boards (two boards per PSU)
2. wait until they finish initialization (LEDs stop flashing)
3. unplug one board from usb hub
4. start hotdrying the power module on board that is connected to USB hub
5. After 15 seconds of hotdrying, start bfgminer on to scan the port in step 4 and start hashing
6. Keep hotdrying until die temp get to 65C
7. turn off hairdryer
8. when temps start to drop to 45, turn on hotdrying again to bring them up to 65C
9. another 1 minute or so, they should stay above 60C
10.  turn off the hairdryer
11. board should be stable around 60C and hash 30+GH/s

One thing I noticed, that each board is behaving differently in regards to temp rise.
I did not cool the boards at any time.  

For me, it seems that getting the boards to 60C and stabilize them there was the key.

Running one bfgminer instance per board is not best solution, but at least they are hashing.

Luke,

Is there a way for bfgminer to instruct it to look at one COM port only?

I have 6 chili boards that I'm trying to setup one by one, but when I enter

"scan-serial" : [ "\\\\.\\COM11" ]

or

"scan" : [ "\\\\.\\COM11" ]

and have two boards connected on COM11 and COM15, bfgminer scans and detects both ports.

Any way to disable the auto scan?

Thanks,

PS. Using 3.10.0, win64

Thanks Mudbankkeith, I'll give it a try.

Ronin,

I spoke too soon, all of the cards I have from Lucko go into SICK state after a while.  Some go there after 30 seconds, some after 30 minutes.
The ones that go after 30 seconds in one run, run longer after restart then go down after 20 seconds after yet another restart.  All I can say, I don't know when they decide to stop hashing/responding.

The whole thing is unpredictable.  No consistency.

Now, regarding that hairdryer fix:

So you do this for each card and run a separate instance of bfgminer, one for each port and installed power switch for each 12V line?

I'm not sure if you have the same symptoms.  Can you confirm?
My cards start fine, they all start hashing, sometimes they all run for few minutes, 30+GH/s each, then they fall off into SICK state one by one.  Usually, bfgminer tries to recover, sometimes it can, sometimes, my akbash watchdog will kill it when bfgminer gets stuck.  It seems that cards stop responding to bfgminer commands.

I'll try the voltage limited version.

Thanks,
af_newbie

Out of 6 cards I got from Lucko, I have 2 that fail with this temp reading error ("Error: Get temp returned empty string/time out").  

The other 4 are hashing at 30+GH/s.  The one with bad temp reading was a defect in the sink, one pipe was slightly lower than the other.
I lapped it to smooth the sink contact.  Worked ok, not perfect, but getting 30GH/s on that defective sink.  

I reinstalled the sink.  Made sure the board is not flexed.  Used backplate with a piece of empty PCB (copper to backplate) in between the backplate and the board.  Looks straight.

During initialization ZlX returns:

PROCESSOR 0: 44.50 C
PROCESSOR 1: 44.75 C
PROCESSOR 2: 41.00 C
PROCESSOR 3: 26.00 C
PROCESSOR 4: 35.25 C
PROCESSOR 5: 40.00 C
PROCESSOR 6: 70.00 C
PROCESSOR 7: 42.75 C

After initialization is complete, idle system, ZlX returns:
PROCESSOR 0: 28.75 C
PROCESSOR 1: 29.25 C
PROCESSOR 2: 29.50 C
PROCESSOR 3: 29.50 C
PROCESSOR 4: 35.50 C
PROCESSOR 5: 42.50 C
PROCESSOR 6: 16276.00 C
PROCESSOR 7: 16303.25 C

It stays like that even after few minutes, 6&7 are reporting crazy temps.

Problem with my installation of the cooler?  Or something else?

EDIT:  I flipped the board upside, fan/sink on the table, board above,  now ZlX is reporting

PROCESSOR 0: 27.25 C
PROCESSOR 1: 28.00 C
PROCESSOR 2: 28.00 C
PROCESSOR 3: 28.50 C
PROCESSOR 4: 35.00 C
PROCESSOR 5: 41.50 C
PROCESSOR 6: -64.00 C
PROCESSOR 7: 28.00 C
                              
So it looks like the sink installation...

That board hashes at ~16GH, Voltages in bfgminer are: 3.29/0.863/12.203, but it is hashing, temp reported is 70C.

I've tried the second board, same cooler type: evo212, it starts out  but then I get "Error: Get temp returned empty string/time out" in bfgminer 3.10.0, second LED from power connector is flashing, after a while bfgminer eventually restarts it, and the process repeats.  Runs for few seconds, submits few "accepted" shares and goes into the error condition...Not sure what can I do.

MrTeal,

Flash utility shows that my chips are running at ~half the speed:

OK


What could be the reason?  This is on Lucko's version of your board (I got them today, this one is first one I tried).
Should the frequency be around 300MHz?

+1, just don't buy from them...

Did you post trust on their profiles?  These dicks should never sell anything here. 

KNC has processed my refund in two business days.  I got my money within a week.

I'd go with the refund on all of them...

Has anyone of you tried to use just the thermal compound instead of thermal pads?
Something like AC MX-4?

Or is the thermal pad absolutely necessary because the chips might have slightly different height?

+1M

Nobody should be buying from these pricks.

What cpu coolers do you guys use with these boards?

Any cooler would work?

http://www.newegg.ca/Product/Product.aspx?Item=N82E16835103099

What are the heatsink dimensions in your coolers?

and you think we can save our environment?  You must be very naive.

I have three words for you: exponential population growth

http://www.worldpopulationbalance.org/exponential-growth-tutorial/bacteria-exponential-growth.html

For OP:  Just find as many H4000 machines you can find.  If you don't pay for electricity, run them all.
Ask all your friends to do the same.

Save environment?  LOL...

I must say, KNC miner is a professional company.  That is refreshing after my dealings with Avalon pricks, AsicMiner and BFL, I can say that KNC is like any other big box stores.

I asked for a refund for my Neptune order (first non-customer batch), got an email the same day, the wire was processed in 2 business days, I got my money today.

I was very surprised.  I expected lies, excuses etc. Got none of that. Was it because they are Europeans? Nah?  They are just a bunch of honest, professional guys.

Way to go KNC!!!

TG sells in-stock products.  BFL sells (now) in-stock products.  
 
I think the plan is to mass produce Monarchs that is why BFL has partnered with them.

If I were BFL, I would go after newegg and amazon.com

I bet BFL wants to flood the market with Monarchs and become an AMD of bitcoin mining.  TG, newegg, overstock and amazon would help them get there.
Maybe their plan is to get AMD interested. You know, to be bought  by AMD would be a perfect exit strategy for BFL.

BTW: Monarch (butterfly) as a product name? Pure genius.

They gave me 7 days warning.  No email though.  I logged in to check on one of my systems and saw the $49/year for two computers notice.

Moved everything to teamviewer.  So far so good.  You can run teamviewer client from a usb stick without installing it on your client PC.  ADL works.
You need to install it on your rigs.  Just use their VPN, it works the same as logmein.  Except it is free.

I paid $13,200 (12,995+shipping) in BTC, at that time it was just over 12 BTC.
Now, I'm getting $13,200 back.  Bought 16.12 BTC with $13,200 already, just waiting for KNC to send me the wire.
