I had one of L3+ ship with a bad control board. Contacted Bitmain about the issue and they responded that they will be shipping out a replacement board for me. Anyone ever had a similar experience? What was the time frame for a replacement part to arrive? Havent received an updated response from Bitmain concerning shipping & its costly & sad to see an L3+ gather dust.

The rear fan on my L3+ was not working when I received it on 20th July, I shipped it out for replacement soon after, until today I still haven't received anything from them yet.

Just a fan? Board issue? I hate to ship it out and lose out on profit.

I ran 1 L3+ on Prohashing and 1 on Nicehash for 24 hours. Prohashing generated $32, Nicehash $36. Are you guys getting similar numbers?

I am so confused about one of my L3+

1) Shows me Socket Connect Failure

I contact Bitmain they tell me its the control board and I need to reset it. I do as told, reset the miner virtually, then via the reset button, next I try to flash a new firmware and new image, nothing is working. The damn thing is rebooting automatically every 3 minutes.

2)

I order a new control board, drive hours to the datacenter, replace it hook it up on a PSU of another customer (mine was still in the rack), it runs for 10 minutes, all chips are ok, no failure message, no reboots all great.

3)

We install it back in the rack, hook it up to my PSU, it runs for 15 minutes and starts messing again. Me driving back to the center, the damn thing turns off completely. Our guess, the PSU is damaged

4)

Today I bought a new PSU and thought lets try it again, I installed the old control board, used the old PSU, its running fine for 20 minutes before all dashboards tell me (0MHs RT)

I replace the board again, with the new one, the miner works another 30 min before the rate drops to 300. I turn the miner on the side like it would be in the rack (multiple miners stacked on top of each other) and the rate drops to 0 again.

I reboot it and now the miner runs perfectly...

WHY did it not run when I was in the datacenter and replaced the control board? why did it power of completely when the PSU is working perfectly today....

Took me already 3 weeks with the miner not running...

Electrical engineer. Mining since 2014.

Follow the official repair guide carefully.

When it comes to inserting the tracking number in the repair ticket,
i's easier when you buy a prepaid shipping label for the package.

Bitmain shop is in maintenance mode, but I was able to find you the guide in Google webcache https://webcache.googleusercontent.com/search?q=cache:b0e1O6KjwpgJ:https://shop.bitmain.com/workOrderGuide.htm

My temps are fine, but I still only had 26 chips showing up on hashboard 2.
Has anyone gone through the return process?
I could use some help figuring how how to fill out the forms.

Chain#	ASIC#	Frequency	MH/S(RT)	HW	Temp(PCB)	Temp(Chip)	ASIC status
1	72	384	126.10	7	I:0O:53	I:0O:59
3	72	384	125.44	15	I:0O:52	I:0O:59
4	72	384	125.50	0	I:0O:50	I:0O:58

1st Write to support, if they told you to send return Hashing board, with send process and information.

By the way, this is link you can follw this process
https://cnshop.bitmain.com/workOrderGuide.htm

But Website is under Maintenance.
Note: shop.bitmain.com is being upgraded from 8PM on 8 September to 6PM on 10 September (GMT+8). We thank you for your patience and request that you come back later.

Fuck man.....What L3+ Miner is this...... Worst.... Hardware..... Its Damage very fast.....
My 1st Hashing board was stop working theni repair tickets and send it to Bitmain with DHL Courier,
After this on my L3+ was running on 3 Hashing board, Its working fine and from 3 days i getting error in one hashing board,
on today few Hours ago, HW error showing board, getting xxx on asic status.
Like this -> oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo oooooooo ooooxxxx

near by 1 week ago i sent my 1st hashing board to.... Bitmain warranty. And now another board getting Problem.
Undecided

Hardware is not proper, bitmain sucks monkey, I pray for everyone L3+ miner should get any problems. Because Bitmain warranty,
systems also not proper takes soo much time, over 1 months.

I was in soo much tension, miner is only 20 days old, getting soo much problems, ROI not recovered, Guys if You want to invest money, You can think this all before buy......

Its luck by chance...
Huh

What were your chip temps?

Chip temps usually run 5 degrees higher so that shouldn't have been the problem. Sorry to hear this man. That definitely sucks.

My board temperature is 60 to 64

Yes resale value is VERY VERY good. Mine before the next batch and ship it = max profit.

Well of course assuming you are in the early batches.

Not true, even the later batches which technically is now are selling very well. The snippet you taken above was in reference to you saying your impression was that ASIC's resale values are very poor.

Machines that are less than 50% the power of the l3+ are pulling over £2400+ at the moment and they are well over 1 year old.

That is great news. Thanks. I pay very low KW/h so the older units are a great option for me. Sometimes you can find hobby miners that are dumping their servers because they can't make money at their rates. A friend of mine bought a truck load of S7's, (A pick-up truck ) for a song. $286.00 per unit. Smokin deal!

I tried to order some L3+ the last batch and I could not get through to add any to my order, spent about 30 min trying.. The frustration is off the charts when ever I try to participate with these preorder's. For a company making millions from a near monopoly of the asic hardware business I am surprised that bitmain still has not fixed there website.

Bitmain ! upgrade your shitty web server, tight c Lips sealed

I bitched publicly to Bitmain on twitter about the buying experience today,
This is their response:

"BITMAIN‏

We are upgrading our servers to improve the experience of our website users. Expect a smoother experience very soon. Thanks for the feedback!"

well that sounds like a bunch of 'hooey' to me ...they are likely gonna do zip as long as they sell out within an hour or so...why spend the massive amounts

needed to upgrade the site ..to take the massive amounts needed to cut your sales from 1-2 hours of traffic jam...to 1/2 hour of better performance

they are just gonna continue to wing it and hope it hangs together imho

The global supply for this batch seems so small. If you want to buy l3+, PM me.

I wouldn't even pay $2,280.00 for a unit that will not even ship until after many 1000's of others have shipped and slammed the network. If you want to sell it for what it's worth by December I'll buy it. That would be $1,272.00. PM me. People that are flocking to buy these for $2,280.00 are smoking crack.

I don't understand where your overly dramatic difficulty predictions come from. Do you just say that to try and get a cheaper price on the miners? There's no way anyone is selling you their L3+ for $2280, let alone your ludicrous asking price of $1272.

Look at the difficulty since the end of August when people started receiving and firing up their miners from the August/September batch that people had to pre-order back in June - which was a huge batch iirc. The difficulty didn't even double! There has only been one large batch since then, and two smaller ones. Worst - extremely worst - case scenario is that the difficult doubles from where it's at now, in which case mining with the L3+ would still be insanely profitable relative to any traditional sense of investing. Us miners are spoiled with insane ROI numbers. We shoot for 30% ROI per month when any other form of investment doesn't even see 30% per year.

LTC difficulty is now at 633k. I know that you know that previous to this batch, 3 days ago, Bitmain sold 18k units. All you need to do is look at BTC and you can easily extrapolate the future scenario for Alt Coin mining. Sometime in the near future, you will make $300.00 p/machine per month. Just look at the types of people posting in here. They don't have the slightest clue what they are doing. I spent 30 years trading and constructing institutional hedge strategies in the financial markets for JP Morgan, Merril Lynch, Goldman Sachs, Credit Suisse etc etc. I have a little experience with this type of herd mentality. I was paid very large amounts of money to extract risk from these firm's portfolios. This is like any other business. When all the sheep come pouring in for the "easy money" it portends at least corrective changes. $1,272.00 ludicrous? Huh

That's what I paid for the batch I'm currently running. Not "ludicrous" at all. Last month I skipped the D3 batch that went for $2,595.00 and bought into the very next one for $1,600.00. It's all about cost. It's all about value and it's all about being rational. Paying $2,280.00 for the L3+ in the current dynamic, is none of those things.

Lastly, this is a high risk business. There is MUCH more in play here than just those ROI calculators everyone relies so heavily on. In trading, we have a term called "edge". If you have the "edge", you can survive. If you give up the "edge" you are just meat for those that have it. Buying L3+ for $2,280.00 is absolutely giving up ANY edge. Just trying to help. Take it for what it's worth.

While I don't doubt your assessment here, I must point out that current difficulty takes into account that Bitmain has the miners hashing at their site. Thus, no dramatic increase as they sell them, rather a lull in the total hashrate as they ship them out. Just my theory.

Wouldn't you see a temporary decrease in hash rate and a subsequent equal increase in hash rate? Looking at the difficulty charts, it seems to just stair-step its way higher without any decrease.
