Hi all, I just received a 1TH-miner. It works well. At least, that's what it looks like. On the interface, it pretends to work with more than 1 TH/s. However, on all pools i connected the machine I never got more than 16 GH/s. Has anybody an idea where I should start to investigate what's wrong with this machine? It basically is this one: http://coinsfortech.com/shop/coincraft-1ths-28nm-asic-bitcoin-miner-with-power-supply/Thanks for every hint!

How long have you left it running on the pool before ascertaining that it only hashes at 16GH?

About 30 minutes on the first two pools, about 15 minutes on the other.

Tried Eligius.st and got there about 16 GH/s. At btcguild only 12, ghash.io about 14 and some smaller pools showed similar results. If it were only one pool showing such a low figure, I'd say it is a question of the miner not being compatible with the pool. But the fact that all pools show such low figures lets me guess that the miner has some issues..

For illustrating the situation here's a screenshot from the miner's gui: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs17.postimg.org%2Fgplxzn4lr%2Fminer.png&t=665&c=QxlSkALuPbVhHg) However, after 20 minutes, Eligius shows me the following: ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fs29.postimg.org%2Fe77bhnzsn%2Fminer2.png&t=665&c=bsSVrCusz32oyA) Now, after 30 minutes, I'm down on 6 GH/s. Is there anything you guys who have more experience see? Thanks Only thing I can suggest is to SSH into the miner and see what cgminer is actually showing rather than the web front end. Because from the stats on the web it looks good.

When I ssh into the miner and try to start cgminer, I just get a segmentation fault if I'm root. When I'm just a normal user, it sometimes starts when I put in sudo cgminer.... however, the output is not verbose, and if I try to start cgminer with the --verbose option, it doesn't start at all. However, it starts perfectly when I use the web-interface. ps -Af shows the following:
sudo ./cgminer -o stratum+tcp://stratum.mining.eligius.st:3334 -u xxxxxxxxxxxxxx -p 0 -o stratum+tcp://uk1.ghash.io:3333 -u xxxxx.6 -p 0 -o stratum+tcp://uk1.ghash.io:3333 -u xxxxx.8 -p 0 --A1Pll1 1000 --A1Pll2 1000 --A1Pll3 1000 --A1Pll4 1000 --A1Pll5 1000 --diff 16 --api-listen --cs 8 --stmcu 0 --hwreset --api-allow W:127.0.0.1
It seems as if they have produced their own little hacks for running cgminer....

Yup, and they claim that I only can use the machine with BTCGuild with the setting 1024/1THs as minimal diff. So this would be a limitation I can't accept. Now that's becoming interesting. When I look at the history in the bash, I see that the name "Bitmine" appears again and again. However, the machine itself is the one sold by the "LK Group" in China ( http://www.lketc.com). But the interface is produced by another company in Switzerland (roxas.ch). So I'll dig a bit deeper into this during the weekend. What would be interesting is if anybody who bought from LK in China has the same issue...

That sounds like a bogus claim, cgminer doesn't care what pool it is, it passes the work to the driver which sends it to the ASIC, mine for another 30 minutes to an hour and if the speed is still 16gh/s, I smell a scam.

Since cgminer is released under a free license that insists all code modifications distributed in binary form must be available on request, since you have received a cgminer binary that is modified from the original, you can ask them for the source code to their modifications and they will be obliged to provide their source modifications within 30 days or they will be in violation of the license agreement and not be allowed to further distribute their binaries or be up for legal action.

I have the exakt same issue. I received my machine 1 day ago and after setting up i was happy. Until today. I normally use Slush pool. I now tried Elegius and GHashIO with same result. Besides that, I can´t login with SSH, i dont have the correct user and password... Anyone know the default password? No info in the box... The webinterface doesn´t require user and password. In the display and also in webinterface all looks perfect. 1.02 Th and WU 12m somethings. Looks OK. BUT. No money, no hashrate on pool side. Only between 1-16 Gh. Mostly 1 Gh.
I am totally out in the blue here. Any suggestions?
Thanks
Urbie

You'd need to run it for a day, but at least you'd know if they were completely full of shit or just a little full of shit.

A device that can only hash in a specific pool is definitely not worth $5000.

At a guess, I'd say that's not the case. I can't think of any reason it would only hash at BTC Guild at a high min diff.

Hmm, my miner.php there is showing you are mining on Eligius ... which has been DDOSed for a few? days.
Although they like to say their magical unicorns can solve all DDOS problems, maybe that's the reason?

You are right that is bullshit. There might be 0.1 % difference of different pools. But That much different is bullshit.
