i am now bitcoin miner ;D ;D

Is it still going at 1500GH/s???
I'm interested. They might've added more chips than needed or in other words, you got lucky.
Are you overclocking it?? On purpose or not/is your miner automatically running it full speed?

Whoa

P.S. Add the image on the forum, people might think that's a bit shady.

Huh? Really? You might be submitting shares at a rate that the pool thinks you're going at 1.5k GH/s when you are actually mining at normal speed.
Heck, hell if I know!

yeah the pool just showing higher rate, what is the actual rate on the antminer GUI page? that will tell you

overclocking  ::)  ???

Do you mind if I ask a dumb quesiton or two.  I just picked up an Antminer S5 a few days ago.  I set up 1 pool at

https://mining.bitcoin.cz/dashboard/

The first day was great.  I saw regular throughputs at the expected 1.10 to 1.12 th/s.  But then it slowly started to go down to around 500 gh/s.  I rebooted it.  It didn't really do anything.  I upgraded the firmware, and that seemed to help .   .  but I"m seeing that the hashrates are falling, once again.


Here's what I'm curious about.
1) I have a 750W powersupply with 2 rails.  I've read that this is very adequadely powered, but can power cause slow performance?

2) I have the unit in a well-ventilated area.  I don't think heat is a problem, but is that something that typically causes performance problems.

3) I see your mIner Status page has multiple pools set up.  Is it simply that the pool isn't feeding my miner enough work?  Should I find multipe pools as well?  Is that a standard practice.

Thanks for any info and thanks for sharing your screen shots.

Well going down to 500 GH/s do you have a picture to show us of status screen?  It likely is starting with both hashing boards and sounds to be going down to one.

But it will be a little more work and info to know why (assuming that is right).

@notlist3d

sounds right, each board would give about 500 GH/S so i guess he's working with just one board now !!

It is not unusual for one Hashing Board to stop for some unknown reason. It will usually not show with xxxx, but the give a way is that the temperature of that board will drop. A reboot will get things going again.

Rich

what about the consumption of this setup? it's probably very high , above 590w, if your ratio is the same as before, i see no reason to overclock
but if you are getting something better like 1554 at 700-800, it would be a good move to overclock the S5
this OC should work with every 28nm board and not so much with the future 16nm or 14nm

Wow mate, u'll get the money you spent buying the antminer back in a few days, don't you?

Thank you, your comment make me  optimism  :-*

Do you know! i' am not using PSU 700W or 800W,  but i am using
PSU GIGABYTE 500W of each Board

BECAUSE I FOUND 750w PSU COST ABOUT 266 USD EACH,  SO I BOUGHT  2 OF GIGABYTE 500W CUST 75 USD

 ;D

Very good today I have updated fan file  https://bitcointalk.org/index.php?topic=928272.msg12321804#msg12321804 (https://bitcointalk.org/index.php?topic=928272.msg12321804#msg12321804)

wow that is some nice speeds

Bitmain generally recommends to use only 1 PSU to power up your miner. Using 2 PSU to power the same miner can cause issues like voltage variations that can be harmful for your miner.
You could use a more powerful PSU to power two miners.
At least, thats what bitmain says. Also, try to use good PCI-E cables. On my local bitcoin miners Facebook page, people use better components to build their own cable.

Bitmain suggests using their own PSU, which is quite a good price/quality ratio

Great.  And can you tell us how much you invested on it and how much youare earning with it?

I would like to purchase one for me.

I think the measurement is wrong. This cannot be true without an explosion in a couple of minutes.

HI, SIR nagatraju

I have Buy 3 ANTMINER S5 FROM ALIEXPRESSSS worth almost $ 1500

Total Revenue   
0.29712346
I make up to date 72.12 USD, because I faced some problems with the beginning


I am now stable at 3000 hash without problems

Thank you a lot

maybe you're right

Yes I know :o you are right 
But I do not want to step, I don't have more cash to purchase PSU

thank you

i found that the time i was a miner i was just a glance of what it is you are very good guys into mining and do risk the profit for next generation of miners and in order to future sell the miners its how it goes not? the roi and some profit then sale to buy another one?

yeah you're right  8)

WARNING! Could be dumb, but I really AM considering an Antminer S2-5

I MIGHT be buying a S5 or S4, ou even an S2-3. Something I can budget in and see what happens.

I will likely buy in October.

One of the specs offered with S3 or so was 500 Ghs. I am thinking of of something like that. Not entirely clear which one

it was, I have it bookmarked so I can go back and get it when the money comes in. If it isn't an anomaly that yours went to

1.5Ths, it really gives me hope. I also have a spot chosen for it by a window and the window opens and we get a freezing cold

Winter, so no tropical place by far. Easy to keep it cold. Simple as pie filling, crust and bake.

Thank you for your helpful tips
 I have changed to cooler master 750m

GOOD JOB

It doesnt explode and it's true, some batches are more powerful and for instance my s5 is the same, I can often find it hashing at 1.7 or even 2.2 th/s, while rarely it happens that hashing power goes down to 550 gh/s. I guess machines need to slow down a bit sometimes or the calculus is more difficult than expected. No overclock no reboot, it's going at 350 mhs frequency which is the default I think. Anyone who gets these overpowered miners is lucky, theyre made with calculators scrapped pieces if you check the manufacturer it's "Texas Instruments" so often Bitmain gets shipped with better electronics to use and assembles better miners. The value of 1.15 ths is the guaranteed one, but many machines happen to have more powerful chips sometimes.

You're seeing the statistical variance of the hashing algorithm.  You should always see lots of up and down, with the average being the rating of the miner (some of which will be better than others, it's a crapshoot).  If a pool is showing a perfectly straight line on your hashrate that is fake news!

That's for sure hashing power fluctuates and no, the pool shows a wave and the administration panel also shows often 1.8 or 2.0 ths so it must be true. Also I read that not all the miners are Texas Instruments so the ones built with american scrapped electronics must be somewhat more efficient :D let's say they have a 0.3 increase in average hashing power

I would like to purchase one

If you're looking for an s5 bro, try to pay it no more than 250$ because there are other models now that can make a lot more bitcoins, but if your budget is limited I must say that any miner is good and will always earn 100+ times more bitcoin than any computer and S5 has low noise and has a fair production per day. Buy it at once if you see it at 100$, it's also got low power consumption. At our lab we just have one of these beauties :) along with 2 s7s which are way more noisier
