2641  Bitcoin / Hardware / Re: ANTMINER U3 Discussion and Support Thread on: January 24, 2016, 06:11:59 AM
it looks like 2 of my remaing 5 U3 are dying too...


AU3 1 seems to have 2 dead chips
AU3 4 has a LOT of HW errors...



I really feel ripped off....

And no, they've never ran past 63Ghs. (and maybe 30/40% of the time, they were at base freq most of the time)

And yes, they were appropriately cooled...

(clic to enlarge)


Out of curosity the one's that seem to be dying are they both at top? Or bottom? Or kinda mix.

Was just curious if there was a trend with your setup on which ones are dying.   Probley not but worth asking.

My seasonic X-850 decided to melt the wires on my s5.. this is actually the 2nd time its done this.. :/

im really not a fan of modular power supplies Sad


(removed pics to save space)
i put an old corsair non modular 750 on it for now..

thankfully all it did was shut off.. the psu still works.. i guess ill throw it in my server and let it have an easy life till it dies..


if bitmain would have used 8 pin plugs instead of 6 pin plugs i dont think it would have had this issue

When used properly, it is actually hard to wreck one of these power supplies. They have a great 5 year warranty and I wish more electronics were built like these.


And I would not say all modular are bad I have some "high" quality modular, which really seasonic should be.  But I like it allows me to plug in cables I need and others I leave in the box no need to have mess of cables hanging around.

But in all reality server PSU's have taken over on a lot of mining.   I'm not sure when I will need another PSU again but likely will be server when I do.

does anybody recieved a tracking ID or a miner device in the meantime?

maybe you should use a new account if you want to reply incognito.

You have to be joking.  Yesminers still have renderings on website.  That is a huge sign of scam, rendering screams I do not exist.

No one has got or seen a Yesminer.   Unless I missed something.
2644  Bitcoin / Hardware / Re: Avalon6 safety or how I burnt my avalon6 on: January 24, 2016, 06:03:41 AM
This is where Avalon support stands out.  Well done by Block C.  Although, 1 thing I don't think is right is that Avalon 6 advertise the Hash rate at 3.5 to 3.65TH everywhere but most will only get between 3.2 to 3.4TH unless they risk it via Over volting to get the 3.7-3.9TH and void warranty.  If this was the case with the S7, everyone would be bitching and asking for compensation.  Why is no one asking for compensation for the Avalon 6?  My brother in law is not impress with Avalon 6 and after seeing this post, he stops trying to get a PSU for the over volting so he's just basically have a weak 3.2TH system.  300GH missing is almost 10% difference!

You can get in the 3.2 to 3.4 area with 11.9. I bought an EVGA atx just so I was using same PSU's on both miners (I like to be tidy).   But they run 11.9-12.1 all seems to depend. Looking back I should have got some nice server ones instead.

Likely if you are using the "12V DC ±0.2V" I think you could get the 3.5T side of things around the 12.2 side.  But as everyone has seen you should not go above that.

2645  Bitcoin / Hardware / Re: ANTMINER S7 is available at bitmaintech.com with 4.86TH/s, 0.25J/GH on: January 24, 2016, 05:57:42 AM
EVERYONE, Please be careful of SCAMMER CCLIU or LUCKYPYRATE trying to sell you S7.  He will pretend to use others for Escrow but then find an excuse to say it's a bad idea and tell you to use LBC as escrow.  Don't fall for his trap.  He have multiple accounts.  Bottom line is, if he won't escrow with someone you trust, DONT FALL FOR HIS SCAM.

When you use escrow as buyer pick one you can agree with buyer on.  Don't just let buyer pick escrow.  If you do that your essentially defeating the purpose.   

Also if you get a PM without asking about buying, or shopping around very good chance it's a scam.  Normal sellers don't sent out random PM's trying to get a sell for the most part.
2646  Bitcoin / Hardware / Re: [Review] Avalon 6 Miner - Winter Mining - Notlist3d - Also FAQ and Help on: January 24, 2016, 05:52:43 AM
Yan is a good guy, that is a funny comment for sure.   The machine does great overtime I have ran my 2 for almost 28 day's and has done great.  One unit was running a little slow today and rebooted after almost 28 days and fixed it right back up.  

When you say rebooted, do you mean just restarting cgminer from the cgminer status page?

Mine kinda happened the same, was running smooth and hashing normally for 2 days, then all of a sudden I see it was only hashing about 1.5Th/s, then I click restart cgminer, and it went back up to 3.3Th/s. It was reporting on the pool too of me hashing that low. So not sure what was wrong.

Wonder if there's a way to detect if it is hashing that low to have cgminer auto-restart. Like maybe a script in the raspberry pi somehow?

Mine was not that dramatic it was like .2 T or so low.   I just did a reboot via gui and was fine.  

And it was first time in almost a month I did anything with it.  They both run very good on their own.  I have not looked into automation as 1 time in a month is pretty minimal for me.   So I'm very happy.

Well, i added the following code to scheduled task as a cron job, and it will automatically restart cgminer at midnight everyday. This should help with any issues people might have by running it for a long time without a restart.

Code:
0 0 * * * /etc/init.d/cgminer restart

@notlist3d, now you can leave it running on it's own forever now... lol

A month is fine with me.  I should check miner more often then that to say the least.  I have gotten use to gear being so good I don't have to do it near what I did in older days.

Stability on these really are pretty great if right setup.

Ok so i just got mine to work  Grin Grin Grin it says its mining at .001 Gh/s while its a 3.6 gh/s chip, the light is still green on it too, shouldnt it change if its mining, im also using slush's pool and the avalon gui

My website is down unfortunately, so the guide isn't working. But you should definitely be getting more than .001Gh/s. Where are you getting that number from? If it is from Slush it may not be accurate.

I wonder the same thing.  Ehash has some drivers and GUI on their site.  It should work/detect and get the 3.6ish.

I would check Ehash out on downloads if your are not familiar with command line with mining.
2649  Bitcoin / Hardware / Re: [Hands On] Bitmain AntMiner S7 - Batch 8 - Notlist3d on: January 23, 2016, 09:09:40 AM
S7 Batch 8 is a good miner for me on up-time.  Over 27 and 1/2 day's uptime still hitting average of 4.7T.   I am using the bitmain PSU on it.


One thing which I saw in S5+ aswell is it seems HW error can go negative if run for around a month like this.   So that is impossible.  But the main thing is the S7 is stable and running good.
2650  Bitcoin / Mining speculation / Re: Should I Buy used or new miners? on: January 23, 2016, 08:45:52 AM
I hate to say it and to be honest but the era of mining bitcoin is basically kind of over unless you have ridiculous amounts of money to spend to increase hash power after the difficulty. You should be aware that if you mine, at some point and time, your equipment won't secure you a decent rate of return on your investment. If you do mine, you should take into account the raising difficulty and the amount of money you can make on your equipment.

At that point is when you sell your gear to someone with lower electricity or "free" electricity.   The hope is the amount you mined + sell price is more then the miner and electricity spent.

Selling has become more and more common it seems.  I think mining will continue for those who enjoy it.  But if your looking for a get rich quick scheme mining is not that.   It is becoming longer and longer time to ROI.  I remember 3 month ROI on GPU's back a long time ago.  Mining evolves we will see that continuing.

Coinbase, simple easy and safe Smiley

better to use full version wallet where you can back up and restore your private key like blockchain.io, mycellium, etc.

coinbase is biggest company in bitcoin world but we can't predict in future maybe coinbase will be shutdown his service
 Roll Eyes


Lol dude. I don't think so coinbase will closee in future until bitcoin goes out from the world. They introduced purse.Io which very effective in bitcoin savings and they introduced bitcoin debit card as well. These kind of big organization which is working on bitcoin will not get close easily.

The thing coinbase has that most dont is a insurance policy.  If they were compromised like say cryptsy was ... the people should get paid from the insurance policy.   Not many have that.

But your giving up having direct control through private key or seeds, etc.  So you are giving up a lot for that insurance policy.
2652  Bitcoin / Mining speculation / Re: Should I Buy used or new miners? on: January 23, 2016, 08:15:02 AM
Like hash72 said.

Don't buy any miners. The price is too high, while the difficulty will prevent you from making profit.
Either buy bitcoins directly or don't. Mining is dead.. for over a year now.

Mining is dad for high electricity price users. If your electricity is more than $0.2/kWh, it is better not to mine. Just buy/hold/use bitcoin.

I think your electicity price is more then what most should do.  At 20 cent's I would not mine on it just to high long term.  Only chance is to mine then sell gear pretty quickly.

I would really want 10 cents or less on electricity before attempting to mine.  And that is including all fee's and taxes.

For home miner, if the electricity price is less than 0.05/kwh, it is profitable to mine even after the halving.

It would depend on the miner efficiency I think once having.  No way do I see say like 1T A1's still being profitable at .05 after having, unless there is a huge bump in value of btc.

With gear being so different you can't really make blanket statements like that.

with the present rate of increase of the difficulty, the S7 will not be profitable after halving.

If true "free" users will have a heck of a lot of nice gear to run.  We don't know what difficulty will be like at having.   And just as important we don't know BTC price.

Your forgetting BTC price does play a part in mining.  We can hope it goes up, it is in no way guaranteed.  So I still think blanket statement's for most part are hard to do in mining, to many factors.

According to me, what is going on is absolutely fine...
Because, some people here make many posts whereas some doesn't, so paying them for those posts at a fixed rate would be a loss instead of what they are already paying, i.e.; pay per post rates...

Weekly and pay per post is better because this is why many are here, including me...

I live on BTC, so definitely not an option for me to go for fixed...

I think everything will be fine and people will be ok after payments are not delayed.  How many people currently have a past date on next payment time? (1-20 for me)
2654  Bitcoin / Mining speculation / Re: New Mining Farm on: January 23, 2016, 05:10:15 AM
i prefer trading. if you got 30k usd? why not use it for trading. and also do research on trading before you enter that field. Cheesy

A surprising amount of people that say i have X to invest, never actually invest.  It happens all the time on someone say's they are going to invest.... then goes silent or decides not to do it.

But right now I think buying looks pretty interesting at sub 400.  If it stabilizes again... could be profit.  And mining or trading no  guarantee of profit.

trading with patience got a lot of profits Cheesy also mining i don't think its good idea to invest on that.

At .22 cent no it wont be.  Which adds to the chances of OP investing pretty slim.

If you truly had 30k to invest would you research it yourself or go to a board and just ask?  I personally would research first... as I find I have to believe in my investments.   Others opinions might give me some good ideas, but I would not go and ask before doing any research.

Funny thing YAN told me that the gear is like a Honda car so  cruise it don't race it.

any one that knows me would laugh since I said this time and time again about the Sp-20  only I said it is like a kia forte! Grin


Yan is a good guy, that is a funny comment for sure.   The machine does great overtime I have ran my 2 for almost 28 day's and has done great.  One unit was running a little slow today and rebooted after almost 28 days and fixed it right back up.  


That is pretty darn good for a miner to go almost a month without needing to touch.  I'm getting around 6.8T after restart.  Normally between 6.6-6.8 area with EVGA supernova's they tend to show up in GUI as 11.9-12.1 volts.  

But I am very happy with the miner's running without needing to be messed with for so long.
2656  Bitcoin / Mining speculation / Re: Diff thread Jan 13 to Jan 27 picks are closed! on: January 22, 2016, 11:14:02 PM
Price had a not so great day so far.  Were at 380 per BTC, so not sure if it was more bad news or what.
Just like hashrate, price has a variance, too Wink

True but we were hitting 410 at points yesterday and now around 380.  Anyone seen news or reason for it?

I know there is variance Smiley  my question was not if there is, but what caused this drop in value.
2657  Other / Beginners & Help / Re: Best bitcoin wallet? on: January 22, 2016, 11:06:00 PM
I never tried another wallet, for me the best wallet is blockchain.info, I've been long enough to use it, although there are some problems but the balance is always safe.

Anyone using it should have 2 factor turned on.  This is very important as without it a simple keylogger could compromise your account.

At least 2 factor makes it much harder to compromise.  Keep in mind blockchain.info is a hot wallet.
2658  Other / Beginners & Help / Re: Looking for proper site to buy and then store bitcoin on: January 22, 2016, 11:04:55 PM
Well, the best method is hardware storage but it is only recommend for professionals. The second best option is paper wallet indeed.

Paper wallet is a valid option just make sure you do it right, if not you can be compromised from when you made it.   Make sure to keep it somewhere secure.

On hardware use one the the well known ones.  And the important thing is to store the seed words somewhere secure.  Normally you write them down and store in a safe place, safety deposit boxes are great for this.

But seed words are just like having a private key if you have then from a hardware wallet.
2659  Other / Beginners & Help / Re: Any way to get BTC back from an unused wallet? on: January 22, 2016, 10:59:28 PM
If that site is really legitimate, it means something wrong with their system. I'm sure every exchange will move bitcoin as soon as they accept it.
But, when i searched about this site on google. I couldn't find any information about this site, so i think this site is scam.

I've never heard of it either.  OP how did you find this site even?  I'm curious as to how you came to it as I think you would have found much better options when searching.

But since you sent coins... no if site is bad nothing you can do to get it back.  Sending BTC is not reversible.

ok, once I change all that the email, password and secret question, I have full control over the account? there is not some sort of password retrieval that would allow the seller access? your awesome thanks for the help

No if there is a staked address they could claim it as compromised or even just a address used in a deal they can sign for.  So are you playing a risky game?  Yes... you are.  Is it guarenteed you keep the account... no it's not.

I suggest raising your own account.  You will learn over time more about BTC and the forum.
