L3+ after 1 month of mining, problem begins to arise.

Today, one of my hashing board experiences the absence of ASIC chips from 72 chips to 33 chips. This results in reduction of 74 MH/s out of 504 MH/s. In the photo below, I reduced the frequency to 350 mHz. and I did the factory reset and firmware upgrade too.

below photo shows the kernel log indicating 33 ASICs were found on chain number 3. It shows that the address scanning on I2C bus only found address for 33 chips. Now I wondered why the remaining ASICs do not response to the I2C bus? Maybe the chips are dead or the chips are not powered? I did swap the connector to check that the problem is really come from that board.

If anyone have had the same experience, please share with me.

Thank you

Hi

The realtime speed is around 8000 but the average speed is at 12,400. I just checked my one day hashrate at Slush pool. It is 12.38 Th/s. I'm not sure why the realtime speed does not show from this board, but it seems to work well for the pass 3 days. Maybe there is a bug in the hashboard firmware?

Thank you for you suggestion. I live in Thailand. After a few attemps to upgrade the lastest firmware, the average speed increased to 12,500 GH/s. But I'm not sure that the speed will remain after restart, so I'm not dare to do it. As you can see, the chips are not really die, instead it seems like a software problem. The shipping cost to bitmain china would be around $35, but I don't want to risk lossing or damaging the board. I have emailed to bitmain support, but no any response yet except the autogenereated reply.

It is not usual "x" everybody know. It will not dissapear easily by disconnecting power. For now I lost 100 GH/s in total. Mine is batch 6 12.93 GH/s model.  Cry

Antminer S9 Hashing Board Issue

My GH/S(avg) decreased from 12,600 to 11,400 due to several "x" on one hashing board. Moreover, this board does not have GH/S(RT) indicated. I restated the miner by disconnect the power a lot of times but it won't help. Does anybody have the same problem? What is your experiance with the bitmain warranty?

My new S9B3 is now pointed at KANO.  Grin
Unfortunately it popped a breaker in my miner room causing me to have to unplug an S7.
I guess I'll have to put the S9 on a Bitmain 240 instead of the two HP PSU's and move one of the S7's to another room. Sad

My speed on the S9 appears a little below spec and the HW errors on one board are much higher than the other two. Board three is currently much higher in HW errors.

EDIT: I had to pull the plug on the S9 as the temps on board 3 shot through the roof.  Huh Angry Huh Angry
Time to move some hardware around.

Mine is batch 2. Seems like we have similar performance.

Thank you guys. I understand that. I've read a lot while my S9 was on the journey. Most online calculators that I use, estimate $16/day in average for the current rate. Do you guys think that's true?

Yup.  Average for the next 12 days.  Then half.

Hope the BTC price will fly up high.

Greeting from Thailand. My S9 has arrived my home for 10 hrs. It's mining on Kano pool, which is the first pool in my life. I wanna see how much income per week compaing to other pools.

Welcome. You'll make more btc here than anywhere else.
gtopba, but just don't make the mistake of confusing variance with total reward Smiley

The variance here is quite low thanks to the large miners we have here, and more will be coming in soon, but of course PPLNS variance is higher than a PPS pool.
Those PPS pools, however, charge way higher fees also.
So in the long run you can expect to do better here.

I have yet to find anyone who needs to pay their electricity bill every single day, so as long as you don't need to do that, you should find that the weekly variance here is pretty low. There will be some bad weeks every so often and also some VERY good weeks every so often.
But even that weekly variance will rarely be very big.

People flock to AntPoo and FUPool coz they think they will be rewarded better.
Simple fact. They wont.
Those pools have lower variance coz they have a larger hash rate, but that variance base that you are rewarded, is lower there than it is here.

Thank you guys. I understand that. I've read a lot while my S9 was on the journey. Most online calculators that I use, estimate $16/day in average for the current rate. Do you guys think that's true?
