Antminer L3+: HW errors...

Hi, i am new here with s9. Is these stats ok? running for over 24hours now, had couple of times lost internet connection.
Thanks

Too much HW on board one, but not that bad either. Chip temp is a little higher, but I believe S9 can run hotter than L3+.
Just try to exchange PCI, and PSU. Maybe give a try to another pool. It is also good to clean the dust inside about once a month. Last thing, reduce the frequency a little.

Maybe some expert will give you better advice. Do not hesitate to ask bitmain as well.

I too am randomly having issues with the S9 and HW errors and sudden skyrocketing of hash rates and then down to nothing and then back again. I am hashing correctly with the pool at 14ths so it is working correctly I am worried about longevity. https://imagebin.ca/v/3kla6B3aXgbb

You have a problem with board 2. Way too much HW. It does affect your hash rate, and might be a sign a short life expectancy for this board. Do you have a modified FW to have different frequency per chains ?

[Shitcointalk]

I have done nothing to the firmware except upload the newest version. I am getting an accurate hashing rate and payout from the pool though.

Interesting, must be specific to S9. Not sure where your HW come from. Maybe you can lower the frequency a little and see if it is any better.
You should try to contact bitmain while you wait for better answer.

Just FYI for you all the miner just stopped working 30 minutes ago. I bought this miner off amazon and have arranged for a refund. Done with BTC gonna look at ALT coins!

Good you can get a refund. You never know how and how long the miner has been used when buying a second hand. Always better to buy directly from bitmain, you get a new product plus warranty at the best price.

Hardware error just happen and are a totally normal part of mining. It is not uncommon to see one board with a bunch more than another, it might have a weak component somewhere. Unless you are seeing 10-100x the errors on one board versus the others I really wouldnt worry about it too much. In the end, there is literally nothing you can do to fix it unless maybe you have a firmware that allows you to underclock the boards.

So on my antminer they are called chain #x  one has 35 the rest have all zeros.  so that's infinity x do I worry?

Hi,


I have it working at 450 with only one CPU making some error (the rest 0 HW) with only 10 HW.

I think works fine.

Any advice?

good numbers no worries see below

[TheYankeesWin!]

So phil  you have a HW rate of 0.0131%

That would mean    99.9869%  is good.

In other words  if you have enough to earn 10,000.00 usd    the errors would drop you to $9998.69

a $1.31   loss for every $10,000.00 earned correct?

[philipma1957]

@ yankees yes that math is correct.

I try to keep  my L3+  at 0.0500 or lower

which means  of every 10,000 usd I earn I lose 5 usd to errors.
