Mine has been running about 19 hours at an air conditioned data center. Chain 1 has 40 hardware errors, chain 2 has 1 error, and the rest have zero.

This seems to be a trend in recent Bitmain hardware. One of my S9's (the most recently purchased one) also has one board that gets 10x hardware errors of the other boards. I tried down clocking that unit to reduce the hardware errors.

Back on the L3+, I don't think that temperature is a factor. One of the hottest boards has zero hardware errors.

I have yet to see a hardware error on my L3+. It's on day 3 of mining.

On the hardware issues what I have seen with the L3's is that if a board throws errors as long as it isn't a high error rate the board is OK.  However what I have seen is that boards in this state can become more unstable over time and as ambient temps rise.  Some of those boards will begin escalating errors until the miner starts to crash. 

So temps are a factor with the boards and HW errors, however temps are usually not the reason the board has the errors to begin with.  The recommendation by many is to disable the auto fan and run the fans as a percentage such as 70-80% to ensure the inside boards most affected by heat are getting more air flow. 

Like you stated this is pretty standard on the Bitmain miners to some boards with some errors.  It isn't a problem unless those errors begin escalating.  This is the dance I have been doing since we started this thread here on the forum with the L3 and the hardware issues.  Hopefully turning up the fans will help some people.  For those in a climate controlled facility this may not be as big a factor.   

Keep an eye on your L3's is the best advice I can give aside from turning up those fans.

can you please elaborate on these data centers you speak of. i would MUCH rathter have my rigs hosted at a reputable site and pay fees than have to deal with the noise/heat from them in my own apartment.

if u happen to know of any in the new england area that would b even better 

I would reach out to Tim at, they will port forward the IP so u have access.

264 bucks for 6 months. Sending my first L3+ to them Monday

Hey guys,
I could host your L3 miners (limited space) in my dorm room. I have unlimited cheap electricity! Hopefully I'll make enough fair money from hosting costs (elec+monitoring) to buy my own L3
PM for address and cost negotiation, but I will def. charge less than what costs you to run it @home
Location: EU Close to the Dutch/German border.
P.S. I could also pay up to 1-1.5K EUR of the price of the miner and get the respective share of the mined cryptos. In which case you'll get electricity and monitoring for free from me as your partner B]

I hope this works for you. If its legit, I would not hesitate to send my stuff to the USA. I pay more than 300$ for electricity per month for each miner....

I know we are super expensive but this sounds too good to be true

lol only poor people?? im not rich but im not poor and im tellin u basing your purchase of these machines on the invo available today isnt very smart. the delivery date is 2 months away and the estimated coins per day went from 10 to 5 in less than a month based on my april 15th batch and the difficulty has been going up and up by around 10% every 3 days so expect to get 1 coin per day if your lucky not including the fees. i cant say its not worth it for sure but the info you supplied to prove its worth it tells me your not planning for the increase in difficulty. you will also see another large spike in hashrate when the later batches shipso your earnings will be even lower. unless they are shipping that miner within 5 business days dont waste your money on them.

I dont give a shit if is not proffitable when they arrive, ill mine and hold till the right moment to sell.  

All the miners who sold LTC at 4 usd for over a year know what i mean, (poor bastards ) you need to mine hold, and sell when the right time comes.

To trade the secret is to buy when the blood is on the streets, same with miners, the secret is to mine when is not proffitable for others  

Did you know LTC is not the only Scrypt coin to mine right ?
