I got a problem when i was rearranging the antminers to get better airflow one of the small parts fell off
Sadly it looks like it never was soldered firm on the board
I have not even touch those at all i was just replacing the ant thats all
Can i solder it myself or do i risk damaging some nearby part if i do.
I only have a simple small solder tool which i used when i made my own flip flop boards back in the previous century

Or do i need to contact bitmain to replace it ?

Hehehe je mag in je handen klappen als ze gaan uitleveren voor mei 2015
En dan ook nog even het goede nieuws ze zijn aangeklaagd voor oplichting voor ettelijke miljoenen dollars
Vanwege niet nakomen van levertijden en gemist inkomen ( speculatief maar wel waar )

I will start to worry if the ant becomes over 60 C
So anything below that lets say around 50 C is not a problem

Best post in this thread for a super long time
I do not know how to scroll fast enough the enormous fud and muddy crap which is posted in between some post like these.
Ding Ding +10

To me MSI is a criminal institution which returns burned motherboards and videocards with a serious defect as non defect and nothing wrong with them to their customers. Which could have a caused a house fire if my very expenssive self bought surge protectors would not had been placed.
So them saying idiot and dangerous things is normal in my view, i will allways try to protect my friends against this company.
Their support is the worst on the planet and does not answer ever in a normal manner.
One advise be smart and never buy from them ever again

 

How come i see so high temps with so many fans cooling them
And all the X's lol
 

I agree on that setting because no matter what speed i set from 200 tot 387 i get to see the whole line keeps changing into XXXX

Hmm you might be right especially since i see no change in hash speeds but i sure would like one of the techs from bitmaintech to confirm or better yet look at this

Because the ultimate test with the fan running full speed showing 4000+ rpm does not change the X's appear after several hours.

So i am sure its not the cooling nor the power , my 1200 watt antec / 1600 watt lepa and 1000 watt nzxt are very capable of feeding 2 ants
While the 850watt corsair became extreme hot when running 2 ants the 3 above do not even get warm running 2 ants.

I like to see scp and sftp on this
When i tried with pacman it seems not to exist.
 

LoL,

I think both are well capable of delivering your ants enough power with ease
The power i mentioned is at the wall so in reality the miner pulls a little less power from the psu.
Because the psu needs power itself to convert and deliver a stable output.
If you but a platinum that power usage is a very small portion less then the gold ones
So it might cost you a little less juice to run the miners over longer periods of time.
However in most cases the extra costs of these does never get repaid by that little gain.
So go for any well known 1200+ psu with 80+ gold

Yes i did never go higher then 387.5 Mhz because i think its not really worth going higher
The one constant showing the xxxx on all cores does seem to make 180 Gh as written by the makers, and so far is not going much faster if i clock it at 387.5 however it seems to be a little faster on 375 Mhz which is in my view still much below the actual speed these antminers can do.
So for some it might be worth the risk goin beyond the 400 Mhz i think the difference will not be worth the small increase in speed gained.
I rather stay well withing normal operations below the 400 Mhz so the miners stay alive for a longer period.
Its just weird that the x's appeared since the box has been placed, but again it does keep running steady around 180 Gh.
Am just wondering if it might be something with the cooling or something, if i let the fan run at full speed the noise is enormous
And even then after some hours mining the x's appear and stay. So i am not sure if it is nothing to worry about or that there is something wrong with this one for the long run.
 

Why are there no new firmwares released with updated cgminer and such ?
Why can't i see in the miner which firmware is installed and which pcb this thing is or do i really have to go the machines to check ??

I assumed if you bought 2 at the same time that i did got 2 exact same machines but i found out both are different
One is a bit cooler then the other and i see different memory numbers
Box 1 shows  15720/29080 i asume this one is 32 Mb mem
Box 2 shows  48336/61586 i asume this one is 64 Mb mem
and is kinda confirmed on the kernel log
The one with the larger memory is constant turning all OOOO into XXXX a some hours mining.
Not sure what to think of this antminer, It does not matter if it run at 350 or 375 it constant ends up showing all X's
I have not tried to set higher speeds because it is already giving enough hw error as it is at 350 or 375
But thats sadly another mess on the antminer there is no speedy weay to see how bad its doing.
I can not use screen and the status page lacks a simple % value

Another nasty habit is that i can't keep the status page open, the freaking overview page does have refresh but the one needed the STATUS page is not able to auto refresh ..... SIGH

I also did not find a solution to keep an eye on the miner by other means

Anyone have a solution for me to see those or know why one runs fine and the other seems to be wacky.
Or maybe i worry to much about the stupid XXXX but then again i paid enough for it, so i want to know if it is having some kinda hidden defect

I have my 2 antminers running with 1000watt nzxt psu and they do fine however i do not use high overclocks if you use 400 mhz or higher 500 tot 525 watt per device is needed minimal
Asic settings found on different topics:

mhz : 387.5
freq_value '5e85'
timeout 38

mhz :393.75
freq_value '5f05'
timeout 38

One miner still constant turns all the O into X after several hours of mining, i have no clue why this constant happens
The Hashrate seems to be according the specified range, but i am worried about this one

Power usage from the 387 setting seems to be 490watt

do you have them connected by usb hub or each direct to the pc ?

Yes you need to delete the cron which indeed runs every hour
You find it /opt/minepeon/etc/cron.d/hourly

This image is an older one because TK1337 has not released any updated since this 0.4.2 release
When i use the latest beta release by minerforeman 0.2.5pr1 somehow the boards fail to run
Still fighting to get them running faster, this far the received replacement board is a super slow one
Only runs at 50:2:850 and not like the others accept 51 or 52
Again non of the boards accept any setting 46/2/950 or 38/1/950 they all fail to run at these.
i need to start them with 48:2.850 to get them alive then slowly up the speed to 50 up to 52
when i put in 53 some do run but they pump in less then 3 minutes 8 to 11 % hw errors.

What baffles me is that if i connect one board feeded by the 4pin and connect it direct to my pc they do start with 48:2:950 but as soon as they are connect to the miniplane/double scroll ..... its back to the lower settings

I am still waiting on a response where are the boys from drillbit
Finally bought a rpi to run the boards i used the image from TK1337 and they instant start mining

Has anyone get a more stable platform since it has a tendency to hang after several hours of mining
The image i download is the 7 version and i installed cgminer 3.9, but ofcourse got a backup from the old one
Did anyone try to run bfgminer on these minepeon clone ?
 

The fan speed can only be adjusted by the machine or run full speed, which is really sounding like a mini jumbo jet
Got mine running at 375 if i go to 387 the errors go up and hash rate actually drops
So mine are not really good ones in fact i think i got pretty slow compared to many others
But to be honest am waiting for the 4 x 140 mm fans to arrive to cool them well whilke not making a noise like a starfighter jet.
This will ofcourse help a bit but if they run faster is probably wishfull thinking
Considering the results which i got already
At 387 i had 278 HW errors in less then a minute

Nah its a learning curve
Just contact me in private if you need more help
You need to be sure which version you have
Since the ones from october need the old and the november batch need the E

the actual fix took 4 days for me
but i am in europe

Wtf only 400 ?!?
Have you checked with latest firmware if one of the boards is defect ??
How many boards does the machine contain, did you check if there are really 4 asic boards ?
Its total bs to say its an early model because that has nothing todo with the performance.

I own a october model and it does run pretty nice

Tjsa wat heel veel mensen vergeten is de invoer rechten welke toch ook lekker doortikken althans als particulier voor mij kwam de invoer op 58,95
Dus op zich hij maakt winst op de verkoop maar ja als hij ermee draait maakt hij ook winst
Nog wel tenminste als niet al die hardware leveranciers die nog niets hebben geleverd hashfast, bitmine, cointerra en dat soort spul.
Als knc die neptunes gaat leveren gaan we het hard voelen vrees ik.

Ik heb 2 antminers gekocht en moet zeggen zijn fijne en makkelijke machientjes.

Het is even een gedoe om uit te vinden hoe je ze aan de praat krijgt maar daarna geen omkijken meer naar erg fijn.
Even ter vergelijking een 700 Gh knc gebruikt net zoveel als deze doosjes die 380 Gh halen
Ik zeg er wel bij ik overklok de S1 tjes maar heel weinig omdat ik nog 4 grote 140mm fans moet ontvangen om deze extra te koelen, en moet nog wachten op mijn 1600 watt voeding
Op zich denk ik niet dat ze veel sneller zullen gaan dan 200 Gh
