witcher_sense hi, i'm trying to send you a direct message with a possible scam case but because i am a "newbie" I can't, any way I can contact you directly? thanks.

Hello Tytanick, the ethernet card from my mobo is damaged and I've been trying to install this USB adapter https://wikidevi.com/wiki/Delock_62417 using this driver https://github.com/geoffreytran/AX88179_178A but it seems impossible, works on regular ubuntu machines but I'm unable to get it to work on SMOS, can you help me?

thanks in advance

hello, any chance of support for overclocking with nvidia cards? the 1060's in particular can mine at 23 mhs with 70% or even less power limit, afterburner only support 8 gpus max, kinda of a bummer with 13+ pcie slots motherboards.

not mining anymore, except for a couple gpu's, into trading and hodling now. While they were inverted they worked fine.

yes, but the thing is, the temp sensors on the ASIC chips (which i guess are embed in the chip, nobody really knows) also report lower temps.

my S9's started failing 80 days in (10 days short of the warranty expiring), got a few boards repaired under warranty. At least now they come with 180 days warranty.

try a few things first, try with lower hashrate (if the firmware allow it) if still having the problem, replace power supply and test, replace or swap data cables (ribbon white ones) and test, if you have more than one miner, try putting the board on another miner, if problem persist just send them to repair.

I don't know if the machine will work without both fans connected, but, you could power the fans with an external 12v power supply, just have to connect the pwm pin to the +12v and it will work at full speed. (with the regular + and - to the other pins also of course).

but are the same fans models right? who controls the speed? is any order you should connect the fans on the main board?

what's with the difference in fan speeds?

bitmain told me that that message is because at least one of the board are degraded (chips burnt) o total damage, try with a single board at a time, eventually worked for me, you have to wait a good 15-20 minutes, but at the end worked. I will recommend NOT TO USE the firmware on bitmain's site, is awful, try to find the stock firmware.

I haven't had these problems with my miners, a lot others, but no this ones, I recommend you to open a ticket on bitmain's website and explain the situation, it seems, I'm not sure, the control board, you mentioned they are still under warranty, use it, because after that they charge between 200-300$ for repair any board plus shipping, before that you could try reflash the firmware, or maybe try the stock firmware they came with if you can find it. the fan speeds look unusual, they should be spinning at around the same rpms, when you open the ticket at bitmain's they give you the option to upload screencaps, explain the problem to them, I think is the control board not sure.

still can't see the pictures, use any other image hosting service besides google, I use  http://imgur.com/

I'm going to explain the situation;

Because of the config of the rack where  I have my miners (with the cables on the back -hot aisle-)
when I got my S9's I inverted the fans of the miner effectively changing the airflow direction,
and they have been operating in that configuration for a few months now, this are the temps I get:

now, I decide to finally take care of the cable config of my rack, and proceed and reverse the
fans config off the first S9, this is what happen:

as you can see there's a 15-16° difference between the 2 settings, anybody has try this?? I thought maybe
the temp sensor is closer to one fan in one config and maybe that's why, but the difference is also
on the chip temp reading, I assume the chip temp sensor is embedded within the hashing chip like most PC's CPU's,
so the temp reading have to be accurate.

any thoughts on this?

recuerda que a lo que le puedes hacer respaldo es al la configuración del minero (pools, freq de trabajo, fans, password, ip, etc), mas NO el firmware, no trates de cargar una configuración que sacaste con un firmware en el minero con un firmware distinto, eso si podría causar problemas, flashea el firmware y te pones a configurar pools etc de nuevo, es mi recomendación.

I don't know, never seen any thing like that, if you invert the fan connectors does show the same reading? I don't think there's a mayor problem but I notice the temps on the 13th one are lower than the 11th one.

I can't see the screen cap, can you please upload new ones? and specify batch number, working freq, screen cap of the firmware screen, psu model, etc.

why on the 11TH appears fan 6 with 15.120 rpm?

ok, si las compraste directamente a bitmain en hong kong, el periodo de garantía es de 90 dias contados a partir de cuando son enviadas (salen de hong kong) si estas dentro de los 90 días, vas directamente a la pagina de bitmain y abres un ticket de repair, ahí te dice después todo lo que tienes que hacer.

si no estas dentro de los 90 dias, puedes usar bitmainwarranty, asumo que te encuentras en latinoamerica, ellos están en colorado USA, es mas barato el envío que para hong kong. abres el ticket desde la misma pagina bitmainwarranty, te tienes que registrar.

si las compraste en amazon o ebay por ejemplo, no te sabría decir por que ahí es un intermediario y no se cuales son sus políticas, aunque si igual están fuera de garantía no te va a quedar otra que enviarlas a colorado por que son los únicos certificados para reparar.

puedes enviarlas usando cualquier compañía de envíos, fedex, dhl, etc.

en la pagina de bitmainwarranty hay un numero (el de venezuela) que te atienden en español, incluso la comunicación por email cuando abres el ticket es en español, Tel: +58-0212-7202127.

yo lo solucione hoy 4-1-17 con el ultimo firmware"Antminer-S9-all-201611290613-autofreq-user.tar" hay que configurar la frecuencia la primera vez que entras, espera unos 10 minutos y eventualmente se conecta. Algunos comentarios, no se puede controlar la velocidad de los fans, y si hay alguna tarjeta con problemas o muerta no arranca el minero, antes por lo menos si una tarjeta dejaba de funcionar el resto seguía trabajando, ahora no, y el auto control de temp es pésimo, tengo un ambiente donde el minero podría tener una temp de chip por debajo de 80° y actualmente el minero que tengo con este firmware esta en 97°, eso es por que tiene los fans en aprox 2200 rpm, y no hay forma de controlarlos, en resumen, si no tienen problemas con el firmware que trajo, NO LO ACTUALICEN, menos mal yo solo lo hice con un solo minero, he estado buscando la versión del firmware orginal y lamentablemente no la encuentro, es S9-B10 si alguien sabe donde lo puedo encontrar se lo agradecería.

saludos!
