[GROUP BUY WORLDWIDE]BTMine v1 Miner 200GH/s BTC 2.4

Also while doing this should I go ahead and pop all the 80 Fuses off and just link them with solder?  This gave me the reason to install my watercooling system so LOL!

With the watercooling definitely please keep us in the loop on temps and performance.  Are you planning on OC'ing, too?  It'll be interesting to see how your PSUs, temps, and performance goes.  If you do, I'd go up slowly since as another user pointed out, these things are very fragile.

What pools are people using these with? Anyone try hooking it up to something called 'cgwatcher' http://manotechnology.blogspot.com/p/cgwatcher.html#download?

I have been using BTCguild and it seems to be coming up with a lower hash rate at the pool end. It stays at a constant 232Gh in OpenWrt and BTCguild only reports 210-220Gh. AT BTCguild I have the minimum difficulty set to 128 on PPLNS. Is there a better pool for these?

Cheers, 

I use CGWatcher and CGRemote. Works great for keeping an eye on things.

Can you send me a copy of cgremote or a link to it please? Thank you

It is in beta at the moment. Info is here: http://manotechnology.blogspot.com/p/cgremote.html

Fair enough, though for me they're actually more efficient - my biggest cruncher before this are/were ASICMiner Cubes, which are about twice as powerhungry.  That said, I'm getting some S1s next and selling my Cubes.

Where are you in the world? My 1/7 has not made it to me yet.

Had to ask for a refund today.  They broke the promise to deliver in 4-5 days.  Then they missed their next deadline that they committed to.  Now they seem to be waffling on their promise to refund my BTC.  Doesn't look good.

[mtnminer]

By following the the blockchain, their wallet is currently empty.  They have been paying out to addresses that payed them prior.  It appears the payout about as quickly as they are getting funds back in?  I hope you get your refund soon.

Can someone tell me about this block chain? Also what is this setting difficulty thing?

[mtnminer]

The blockchain is the open record (accounting ledger) of bitcoin transactions, it shows transaction by wallet id and amount.  https://blockchain.info/

You can see the transaction for the Chinese Avalon Clone seller by searching their wallet address in the upper right hand corner of the blockchain page  1Ju8uMyLRhqstEUZKRBbqMwq7seUfnVGZq

The green arrows are bitcoin in and the red arrows are bitcoin out and every associated address.

Difficulty

The difficulty thing, is the automatic adjustment attempting to control the time in which a bitcoin block (equation) is be solved.  This increases as the network hashing power rises, guaranteeing we will still be mining bitcoins until 2040 and not mining them all out sooner.

This is a simplified answer, but the general idea.

[grumpy619]

I guess what I ment about the difficulty thing I was talking about is I saw some people setting there difficulty on their machines? Thank u for clarifying the two for me.

Got my two today, neither in a fully usable state ! One has a broken capacitor like the above users and the other has a severed cable to one of the modules. I'm guessing these cables are standard IDE cables? I'll have to go searching for one, haven't used one in years.

I'm glad to have them but it's clear there was no quality control being done once they were put into cases. Will work on them tonight and see if I can get them hashing away.

[trinsic]

I paid 7/1.

Got three of the four modules hashing now, will look into getting an IDE cable and fixing the broken capacitor one tomorrow.

edit; ok a quick search shows that it is not an IDE ribbon cable. Guess I'll contact BTMine.

New problem. I have a module hashing at almost exactly 50%:

   [match_work_count1] => 5817
   [match_work_count2] => 5752
   [match_work_count3] => 5846
   [match_work_count4] => 5877
   [match_work_count5] => 5836
   [match_work_count6] => 5674
   [match_work_count7] => 5848
   [match_work_count8] => 5678
   [match_work_count9] => 5680
   [match_work_count10] => 5894
   [match_work_count11] => 5872
   [match_work_count12] => 5861
   [match_work_count13] => 5746
   [match_work_count14] => 5866
   [match_work_count15] => 2934
   [match_work_count16] => 5712

Not sure the issue. I'm at 1400MHz. This is on a module that doesn't have a FUSE1.

Here is 2 of these babys hashing away. Dropbox fails and rotated the video 90d download to view propelly.
Sound is not that bad from the unit which has working fans that report RPM ~2500 it's not loud at all.
Left unit in the video has fan RPM report 0 in the webpage and it's fans are stuck at 100%.
All cables connected but i'll propably replace the fans later.

luv my babys they are hashing nicely and i got more coming tomorrow.
Sofar so good. i let them warm up then replacing psu etc.

more photos coming.

First one of my units had ugly dent on it. I suspect someone has dopped it at factory.
Stock PSUs are two Rail 12v 25A

Both of my units are hashing 180GH/s ..... out of the box. Further inspection shows their QA too bad they are in a hurry and tired.
This is what i find.




After fixing those broken pins my miner is doing 220GH/s now. Reported hash in BTCGuild 221GH/s
 


So be ready to QA your miners. I'm opening the second one now.
-Edit-
Disassembling and reassembling the scond unit brought life to those 2 missing modules didnt find anything wrong but after careful reassembly it's hashing 220 too now.
Quess the backplane was loose in that unit.

ps. DHL picked up more units for me

thanks for sharing
happy mining:)

You can control fan noise with --avalon-fan in CGMiner extra settings.
