ASICMiner Tube Group Buy #2

[xhomerx10]

I looked at this pool too.  But at 60 Th/s the likely hood of hitting another block is pretty slim.  I mean hitting the one on 9/11 was miracle really.

 On average it should take 25 days to find a block with current difficulty.  I wouldn't call it slim but at the same time, I don't like variability all that much so I prefer to pick a larger pool and go with the 1 coin per day.  In the long run, it should all work out the same but mmpool gives the block transaction fees as a reward to the finder.

Has anyone had this happen:



Put unit together, powered up with power supplies that had been running another tube for about two weeks, about 10 minutes and POP!

Now the first tube is back in that spot hashing nicely.  The one with this bad chip is elsewhere hashing on three boards.

Does anyone have any experience with the RMA process?

If you bought from Canary PM him and send him the board. I just got a bad board back he sent in for me and was a pretty quick turn around about a week  1/2 or so.

PM'ed and E-mailed yesterday, and haven't heard anything yet.  He is most likely just busy.

[helipotte]

Still have not heard anything at all.  Starting to get worried.  Maybe he is on vacation?

Sent E-mail to canary.btc@gmail.com twice.

Sent E-mail to help@bitquan.com.

Anybody got any spare chips?  Looks like I am going to have to fix this myself.

In a PM he told me he is unavailable until late September.

 Friedcat has a boatload of chips left.  It wouldn't be that difficult for him to throw a few in an envelope and ship them to you... and it couldn't hurt to ask.

He probably meant ghash went down so he joined mmpool as an alternative.

Yes and your suggestion to join mmpool  has made my life really interesting.

  I found a problem with zencloud-gawminers due to using and testing mmpool with westhash purchased hashing along with using the asicminer tubes.
I do not know whether to like you or be mad at you. Well the flaw I tested for in mmpool does not exist but there was a huge flaw in part of zencloud-gawminers product line.  They had to end/transfer all of the nicehash section of their business.

That was an interesting post- got me to try pointing my tubes to mmpool (where they've been miraculously stable compared to the other pools I'd tried them on) and that zencloud bug made for quite interesting reading as well.

and bam mmpool.org hit a block I got 1.6 btc  35% cdf = score in a high variance pool   these tubes made me 2x roi due to hitting 2 blocks at mmpool.org

Since I joined late on the first block and tons of miners bailed out I got 1.25 coins .  the gaw discover made me about 1.75 coins and I made a block on mmpool.org today another 1.6 coins.    this is 4.6 coins - 2   in expenses = 2.6 for 2x tubes in about  20 days.  my cost was  about 1.9 to buy them profit is .6 btc and 2 fully paid for units.


 True luck.  as I should have earned about 1/3 that.   and should be about 1 coin in the hole.

Just got 4 Tubes.  in hand, ready to ship.  if interested, PM me.  payment would go to address posted on OP of this thread so don't fall for scammers

[CanaryInTheMine]

2 tubes are gone. 2 remain

[jdany]

Tubes arrived today.
Everything perfect, as usual.

I cannot say enough good about Canary.
An asset to the BTC world.

Thank you

I've got an extra BE controller if someone is looking for one.

Also have a few extra USB interfaces for Prisma's.  Tubes may be able to use them and then run cgminer instead of using the BE controller with Tubes.  anyone test this?

I have and the tube runs great under cgminer. Only thing you need to do is pass --bet-clk 26 to cgminer in-order to set the clock to 270Mhz.

Is your hashrate 830gh/s+? On the BE controller my unit hashes fine. On cgminer with --bet-clk 26 I only get 760gh/s average.

Canary, how much for a BE controller?

[Icy]

Yes. I've found that it takes a few hours before a tube averages out in cgminer. Maybe try a slight overclock with --bet-clk 27?

Thanks.  For whatever reason, the config file cgminer was loading had "bet-clk" saved as 23.

Canary, I might take that extra BE controller.  1 out of 2 would not connect to the boards, 1 hashed fine running both tubes for about a month maybe more.  After some power cycling from maintenance, I now cannot get it to interface w/ the boards.  Apart from re-flashing, changing settings, changing ports, etc. do you have any recommendations to get the boards to connect, or should I get the new controller?  I pickup the controller on my network no problem.

[Adrian-x]

I just got a seek thermal camera for my android phone, way cool nice toy for my current project.  

anyway this is the first image i took with it, it's of one of my tubes.

Was this group buy resurrected by the previous comment.  Probably should be marked as closed in the title.
