361  Bitcoin / Hardware / Re: ASICMiner Tube Sales Information Thread [Round2, Price Down to <1btc per TH/s] on: August 31, 2014, 11:22:31 PM
Looks like you can set a failover, but it doesn't revert. If your first pool goes down it switches to the second, but it doesn't periodically check the first for activity and switch back if it comes online.
No, indeed not. For the time being the failover mechanism in ckproxy is the equivalent of the "round robin" in cgminer.

Does the ckpool web interface offer anything when running as proxy? If so is there a guide on setting it up?

He posted the link to it earlier.

https://bitbucket.org/ckolivas/ckpool

He's running ckpool in standalone proxy mode.

Use the code directly from bit bucket or is there modified code base?
Directly. It sanitises to slush stratum based pools only, though there are quite a few of those.

OK I'm giving it a shot.

In standalone proxy does it failover upstream?
363  Bitcoin / Hardware / Re: ASICMiner Tube Sales Information Thread [Round2] on: August 31, 2014, 01:38:12 PM
I was having issues earlier connecting to slush with one, but it's working beautifully through the modified ckpool proxy. Might try again later and see what was up.

Is this proxy available for download? Cheesy

also wondering this. using BFGminer as proxy gives me particularly high reject rates (although that could be some settings I need to change?).

How do these chips respond to heat? Do they clock down if they get too hot? Or are they just less efficient? Is there any thermal sensor on the chips or boards, or is an infrared thermometer my best bet?

Reason I ask is I'm thinking about a less noisy cooling setup, and I'd like to know how hot is too hot.

Canary, have you been able to determine how to RMA a bad board we purchased in your GB? I haven't been able to get a answer from anyone yet?Huh

I'm also looking for this info.
367  Bitcoin / Group buys / Re: [OPEN] ASICMiner Tube Group Buy #2 on: August 29, 2014, 11:18:25 PM
Got my 2 tubes running on 1 controller, no problems, no hiccups, no issues at all.
Getting a steady and stable 1.6T since last night on poolside on Slush. Sorry, my kill-o-watt died so I can't verify draw at the wall.
I'm using bfgminer 4.7 as a proxy, but I hear Slush got it working w/o a proxy so I'll have to try that.

Otherwise, I LOVE this product. The engineering on the kit is far superior to the usual BTC world crap. The tube concept with one fan and interlocking heatsinks is great and very efficient for cooling. And I really like being able to run 8 tubes from one controller. The other good choice was using a thermal pad instead of paste, mainly due to the apparent lack of workers skilled in thermal paste application techniques.

So kudos to friedcat, and kudos to canary for running this GB and superbly handling the daunting task of packaging all these units, and so quickly!

Now if only AM could improve efficiency a hair, they could give Bitmain some tough competition.


did you daisy chain all 8 together?

Hi everyone.

I am having an issue with this purchase and I am hoping someone here can help me. I came across the ad for this buy and decided I wanted to purchase one of the tubes. I did not have the required BTC in my wallet so I sold some GH/s from CEX.io and sent it to the address listed in the ad. I posted my tx ID on this forum and purchased and emailed the shipping labels for the tube. I received an email back from Canary saying everything was fine and all I needed to do was sign the message and send it to him. I had no idea what Canary was talking about and was informed that I could do it from my wallet. When I told Canary that it did not come from my wallet but from CEX.io I was told the ONLY option was to sign the message or the BTC would be returned to the sending address. I immediately emailed CEX support and explained the situation to them and I was told that the receiving address at CEX was static but the sending address was not and if the payment was returned I would lose it.

 I then notified Canary about this and was told it wasn't true and that the ONLY option was to sign the message or he would return the BTC to the sending address. I once again emailed CEX support and my ticket was elevated to the supervisor and they responded with the same information and an offer to contact Canary and confirm the transaction came from my account. This was rejected by Canary. Canary posted a message to the admin of the GASH.io forum stating the problem and after some confusion the admin at GHASH told Canary the same thing CEX had. The admin also offered to confirm the transaction came from my wallet but once again Canary rejected this.

Canary states that I can not prove the funds came from my account. I have asked Canary if anyone else has claimed this transaction ID and to this point he have refused to answer the question. I also asked why the confirmation from CEX was not adequate and again no response from Canary. Canary also will not answer any questions about this transaction. Canary will only state that the ONLY option is to sign the message, which is not possible or return the BTC to the sending address which means I will lose it.

I sent the BTC to the listed address in good faith and have offered to show that the funds came from my account on CEX. I am at a loss at what to do now. If anyone has any ideas I would very much appreciate hearing them.

Thank you,

Stephen Scott

I don't know how GHASH can prove it came from you unless they can send a signed message from the same address...

about a dozen Tubes are available.  beginning to run low.  can ship out in the next 2.5 hrs today.

Does this include shipping replacement for posts that showed up broken? Please let us know how you intend to replace boards that showed up non functional, or if it's even you I should be contacting about this.

(sent you PM about this but maybe you didn't see it)

Yeah hit the back button and refresh the page manually. Flashing takes maybe 10 seconds.

what version does it show after the flash I am showing 1.41 still.

Mine are 1.41 after initial flash.
371  Bitcoin / Group buys / Re: [OPEN] ASICMiner Tube Group Buy #2 on: August 29, 2014, 07:49:40 PM
okay I have it assembled.

I am using a 5 volt dlink 1mp wallwart   so it works fine.  the controller has flex on volts.   5 to 12? at 1 amp seems to be good.

I am using an evga 1300 psu 4 pcie cables attached
dip switches:

  set 1
then 2
then 3
then 4


I typed in
192.168.0.254:8000/FlashMega and I am at this spot. flashings seems slow so far 10 minutes.

Any time estimates for flashing?



Doesn't take particularly long. The page doesn't refresh back to the settings though.

Will this compile on cygwin?
I don't regularly test it, but it did at one point.
Very recently, git has some changes that could interfere with that, so if you have any issues, please let me know.

If I end up going that route I will let you know. Gonna try out an openwrt build first.

Canary how do we handle bad boards I have one with a bad chain in it also. Hashing at 181.

SNIP

Also sidehack sent you a pm on worker.10. I was also able to get the device to work on slush running it through BFG Miner for windows.

SNIP


I got it running on eligius through the bfgminer proxy as well, but it keeps crapping out. I get an "error from bufferevent" message and then the controller stops responding.

I am seeing this as well.  An older version of Bfgminer seems to be more stable.  It also seems to stop when a block is found on the

network.

Edit: Just checked, now the boards are showing F/W version 1.53.  Must of just updated last night of this morning.

They updated themselves? Or they need another FlashMega?

I think warranty is done through the reseller, but I could be wrong. So far I have identified one board for sure to be replaced, one that's behaving erratically and one entire Tube that's nonfunctional but it's probably one board hosing up the serial line. Tomorrow I should have a final count on what does and doesn't work.

yep I have one board that doesn't respond to anything and if it's in the chain it disables everything else as well.

another board will run for about 2 minutes then causes instability and then disappears. with those two unplugged, though, it's been running stable.
376  Bitcoin / Group buys / Re: [OPEN] ASICMiner Tube Group Buy #2 on: August 29, 2014, 05:10:54 AM
I think 2 of my 8 boards are dead. Who do I contact? the email addresses, usernames, etc in FC's first post?
377  Bitcoin / Group buys / Re: [OPEN] ASICMiner Tube Group Buy #2 on: August 28, 2014, 08:47:48 PM
I got mine too. Just gotta finish up some things around the office.

Are there any guides for getting this thing from in the box to hashing, aside from the overview video and dogie's guide?
378  Bitcoin / Hardware / Re: ASICMiner Tube Sales Information Thread [Round2] on: August 28, 2014, 03:02:13 PM
So I can run 2 tubes from 1 Ethernet/controller yes?
379  Bitcoin / Group buys / Re: [OPEN] ASICMiner Tube Group Buy #1 on: August 26, 2014, 09:32:32 PM
The Cubes required the proxy because they only ran getwork. These guys do stratum natively, but apparently they don't do it quite right. Either that or every pool ever has implemented their standards wrong but every other hardware ever somehow compensated (which seems unlikely).

If I knew any python, and had any time at all, and knew more about the stratum packet formats, I'd consider tearing into the proxy and seeing if the erroneous portion can be spoofed and get a proxy going that'll fix the issue with these at least until there's a firmware update.

Would this be of any use? I've seen it recommended by various people/pools:

Btw I don't get why everybody is crying here because of low hashing power prices...these prices are directly linked to coin mining profitability. And check the coin profitability charts now. THIS is the reason of crappy prices. The sinking altcoin market full of scams and pump'n'dump projects.

I am a miner and I had to shutdown 14 AMD cards last month because of this. But I don't blame NH.

Litecoin mining profitability is atm 0.38409727 BTC / GH / day, Nicehash is currently paying 0.3922 BTC/GH/Day for scrypt to its miners. Highest running order is 0.42. Why would anyone pay more than that and lose money?

Also miners are not forced to mine on NH, they can setup the minimum price a mine elsewhere in times where they are not satisfied with current price. This is self-regulating environment.

Also arbitrage bots can drive the price higher in case the average price on NH drops considerably below coin mining profitability. But this is not the case here.

I think prices on nicehash are completely realistic and in order with current shitcoin market situation.


People are yelling, screaming, crying, and whining because either they feel entitled to something that they are not, or they employed flawed ROI calculations when originally making their decisions to purchase mining hardware -- most likely by assuming a fixed fiat value of daily earning potential at acquisition and erroneously applying it as a constant in their break even and profitability calculations (or failing to account for the possibility of its rapid decline).  And rather than blame themselves for being in trouble on their investments, they want someone else --anyone else, to blame for their poor current situation.  If westhash never came into existence, they would be blaming some other demon right now.  [It has been mildly amusing though, so by all means please keep it up.]


I more or less got screwed-ish because Vertcoin dropped in value by 83%. It wasn't a flawed calculation. Then again, I'm not complaining about NH/WH rates either...
