After 2 months of mining the most time the L3 worked without faults, just one time it dropped 1 hasboard but after the reboot it came back for regular hashing. Few days ago the miner crashed and when I checked the miner status I noticed that the board2 loss 4 asic chips, and I was surprised that this was not hashboard3 that always generated a lot of HW errors. At this time I can't get 4 asic chip to come back up even after the reboot. I contacted Bitmain and they confirmed that the repair cost is around 35 USD for each board without warranty, plus shipping cost. I'm going to create a repair ticket and ship the hashboard back. I just hope to get help from Deep In The Mines to create a return label with their discounted shipping rate.
I noticed that the hardware defects are starting to appear after two months of use and the example is my L3 and two L3 from Longsnow.
Anyone minnig more than 2 months without serious issue?
This is exactly why I posted my saga on the L3's here. My L3's ran fine for a while also. But just like the S9/R4/T9's they almost always seem to start off working just fine. Then the problems start. So that is why I hoped to share this wisdom with people here about the L3's and to be aware that the same issues that Bitmain has with their other miners are here on the L3 also. They just don't make a reliable miner.
However warning people isn't enough because everyone thinks that "accidents" and "problems" happen to other people. So we continue to buy this junk thinking it won't happen to us. The cost of shipping unless you get lucky to have someone help you like "@Deep In The Mines" to let you print a shipping label with him will cost you a fortune even if the board repair cost is reasonable.
Next problem is that when you ship back to them it goes to a Hong Kong address. From there once they get it they told me it can take 5-10 days for it to be shipped to China and processed through customs. Then the repair can take place. No estimate on that time required. Or the shipment time to get it back. So at this point I think I am probably being very conservative when I say it will likely be at LEAST 1 month before this is all done and the board is back. Sadly I have 1 hash board out for repair and one controller/io board out for repair. Just waiting for the next board to bite the dust while I am waiting on the stuff I have already shipped to get shuffled around, fixed, and sent back.
So I know I am probably wasting time sharing this experience with people, but hopefully it will help a few people who will take heed. Until these miners are sold in other markets and you have someone like "BitmainWarranty" doing repairs locally the time to get a board repaired is very long and the cost is high. Even with local repair the cost is still high. So take it for what it is worth.
I won't be in a hurry to buy more L3's and certainly NOT the L3+.
maxumark has a hosting plan and L3 ON HAND (you pay $2550 (100 bucks off thru monday 4/3/17) its the works. Also includes REPLACEMENT hash if you L3 decides it needs
to take a trip back to china...I've been hosting with him for a year.....er he also includes the PSU in above and again elec and everything for the year price (best plan)
He may only have 10 or so in house.....for purchase or the hosting plan.....just saying
https://bitcointalksearch.org/topic/sold-antminer-l3-250-mh-scrypt-miners-hosted-included-1802108Anyway ...I've been hosting with him for almost a year and the last of my knc titans are going there..I"ve just grabbed 3 of these deals. We will see chump or champ
easy to be brave at 10c kwh on such deal (not like some of you guys with 5c kwh prices) and current $7.36 usd priced LTC
anyway asic gambling again...the bitmain L3 may die like it has for others...but with the hosting.....while it vacations in china ...i'm covered.....
again for you guys with (pretty) 5c kwh this does not mean much...for me who has current (heated house) winter elec rate of 10c kwh and going in a month to 13c kwh
this was pretty much a no brainer gamble for me
I also have been to his house...had my stuff hosted with him for a year....all my 3800mh of pow scrypt will be in the data hall soon....talk to him 2x a week and I will act as 'escrow' if need be....others on here know he is legit...again this is the same price dealhe had at 4.15 usd LTC..just a moving them out at the same price to get the word out he is legit and will be continuing to offer as best a deal he can in the future..again going fast I'd bet half he has are gone already ..either sold or hosted
we will see.....chump or champ indeed...asic gambling again...off the frigging wagon
