The Habanero - 650GH/s - OOS

[nexus99]

Hi all.

Anyone see this?

One of my cards, no matter the clock setting, will, after a couple of minutes hashing, display the error:

"No valid hashes for over 6 seconds, shutting down thread."

It usually never gets over 97c.

Any ideas? My other board seems to be hashing ok.

I am going to pull the pump and reseat it... although i can't imagine why that would help.

Hitting the reset button gets the board going another few minutes.

Just got this forwarded on to me from someone who received it in a PM.

Hi,

The miners are shipping from the US but if you prefer I can process your order directly and mark the package as a low value for duty purposes.  I could mark the value as $150

Current price per unit is 1.28 btc inc express shipping.

If you want to place the order the payment address is -

1LUTUHDD1HXSqg8VQQzxYv8CXKyQkXXXXXX

After payment pm me the transaction I.D and your shipping address.

Thanks,

MrTeal.

That's not me, obviously. Don't send that guy money.

Thanks Canary. I almost hesitated to report the user. Didn't expect as much reaction.
Now I'm glad I did.

Son of a gun! Finally got the coin together to pick up a pair and they just sold out according to the website.

Same here. I was just going through the checkout from having a few in my cart.
Stupid trip to WalMart.. 

[sidehack]

Yep, running errands while deposits confirmed and out of stock when I got back. Grumble grumble... Hopefully there's a batch 3, I was really looking forward to playing with these.

[Airwhale]

Yeah,  I just got the bitcoins to send my order,  and it is out of stock! =(  Here is to hoping for a batch 3 in the near future.

I've got some from batch 1 that we are building into systems. I have a few extra bare boards that we can probably part with. Sidehack, I would double check tomorrow to make sure they are definitely sold out. If so PM me and I can probably hook you up.

[MrTeal]

Hey guys, sorry for the sudden take down of orders. We had a large order come in that swept up a bunch of what would be the remaining stock on this batch, and we took it down as a precaution. Nothing so far is indicating yields are bad, but since we still have the last parts of the batch to test tomorrow, we pulled orders down pending getting a final count on the number of boards we'll have available and our final stock status going forward. We should still have more, but we want to be absolutely sure that we don't oversell the batch and not be able to supply everyone in a timely fashion, or move all the boards out and not keep a few in reserve in case an RMA comes in.

Now I feel like I'm waiting online for an NCIX sale

Now, that I can't have one I want one even worse especially with the release of the software to make your card explode by altering the voltages (not really, but that would be my luck).

The other trick that is being used lately is replacing one letter in the username see this example:
fake profile- bobsaq3
real profile- bobsag3

The g and q can be tricky to spot if you don't pay attention.

Finally managed to fire up one board (was making frame for it) and noticed that 850MHz gave me around 630GH/s then I have tried 900MHz and it gave me 600GH/s.?

Not sure if it is my PSU or Voltage. Voltage was 0.86.

Just ordered 11 of the Habs.. Can't wait!

I have a RaspberryPi which I was thinking of using as a controller.

How many Habs would a single RaspberryPi handle? Or should I go with something more stronger like an Intel NUC. I don't mind purchasing multiple RaspberryPis, just wanted to check with someone that had experience with it before I placed an order.

Any downside I should know about when using the RaspberryPi as a controller?

Connected second board and CGminer is crashing with a note "thermal overload tripped"

It doesn't start mining at all so not sue what "thermal overload" means.

One more thing- where Hash rate should be it says "ZOMBIE"

Any help or opinion is appreciated.

[MrTeal]

It probably tries to start mining, but stops before it actually gets shares. Double check that the cooling head is mounted good and you have good contact, and also with all the fans off just plug in the pump and make sure you can hear/feel the pump running. I have a couple that would immediately thermal overload, and in both cases it was that the pump on the cooler was dead.

HAAAAAAAAAAAAAAAAAA

Yep yep yep tralalaaaaa

1 water block wasn't tight enough

Thank you very much

These are stand alone miners, are they?

No.  They require a controller via USB.

Try running the Pepper app. What you'll see if you go too high with insufficient voltage is that dies start stalling, and the temperature will drop.
I got these from gateway last night, so I'm pilfering them but attribution.

This is a board at 950MHz, with different voltage setpoints.
930mV


940mV


950mV


970mV


You can see the temperatures drop constantly at 930mV; the chip is being starved for voltage. It's much better at 940mV, and at 950mV three of the dies are running fine. At 970mV they're all running good.
With the python script gateway posted you can even adjust the dies individually. For the above case, you could do
./hftool.py -w 0:950@950,1:950@950,2:950@950,3:970@950
That would set the first 3 dies to 950mV and the last one to 970mV

Note that cgminer overwrites the frequency value (the number after the @) with it's setting, unless you use --hfa-hash-clock 1
That can be useful if you're really trying to push the board. You might end up with a die that just can't do 950MHz even at higher voltages, but the other three can get up to 1GHz. If that's the case, you can set the defaults for that board individually and run some of the dies faster than the others.

Fantastic post MrTeal

It looks like I can't go any higher than 700MHZ

My set up: 600L/h pump + triple radiator (2x 3000rpm Ultra kaze 120mm x 36mm and 1x 1900 rpm ultra kaze juny) + 2 custom aluminium water blocks as additional cooling before water enters radiator.
CPU blocks are cheap chinese I had laying around.

Your post is perfect but it's far too advanced for me. I'm using your tool which displays Die temperature BUT for 2 boards it is displaying only one set of dies. No clue which one. If I have 10 boards I would really need to see 10 die sets so that I can adjust them individually.

Hashing never stays constant it goes like 400Gh 2 seconds later 532GH than 680GH than 415GH. Up and down like roller coaster.
