I submitted the ticket 5 days ago but it seems their support department does not work these days. I also tried to email the staff who is assigned to my case but no reply from her so far. I tried to message Bitmain via FB and Twitter, no result too. Anyone got reply from Bitmain these days? Do you guys have the support staff email like Janet, Bella or Barbara so I can email them directly?

The problem is quite urgent since my bank does not allow me to send bank wire to Bitmain due the amount is pretty big, and I can not provide the a professional contract but only a simple proforma invoice. My request is just  to change the payment from Bank Wire to BTC, but it seems it s very hard to get their attention these days 

Hello, as the title, anyone has received shipped email from Bimain? Today is the last business day and it is supposed to ship already. I emailed them 2 days ago but their support is quite slow this time. I thought maybe thy acrually shipped but has not marked the order as shipped, but if you guys have any information, please share it to me. Thank you so much.

Hello guys, so one of my L3+ suddenly stop working as normal, it automatically reset after 2-3 minutes. I check the miner status and it seems the hash-board number 2 is defective, it just does not show up, only the board 1-3-4 are there. I understand that I can remove the defective board and send it to bitmain to ask for them to fix it, but in the meantime, can I assemble to L3+ again and run it with only 3 boards? It seems the design is similar to the S9, so anyone run S9 with only 2 or 1 hash-board before?

Here is the screenshot of my miner status, do not know why it does not show up with the post, I insert the link between the IMG tag.

Guys, I have a question regarding the GPU, yesterday I moved my rig with 7 cards to the new location and assemble it again, but stupid me I somehow put the usb riser for the 7th card like this

The small port of usb riser was connected to the wrong port on MOBO, when the wide port of riser connect to nothing.

And then I boot the rig with nvOC, of course it only recognize 6 cards, I checked and saw what I did and I immediately shut down the rig and put the usb riser in the correct port. However from that time my rig can not recognize that specific GPU. I tried to:
- Unplug all others GPU and use only that GPU but the window or linux can not recognize it
- Install driver but it does not help too.
- I plug the HDMI cable from the monitor to the gpu, but it does not help.
- Plug the gpu to another working rig, but it does not help.

The GPU fan and led is still running as normal, there is no smell. But I wonder if I accidentally shorted my card? Sadly it seems the warranty will be voided if the card is fried or shorted.

I really appreciate your help.

The card is Galax 1080ti 11GB

[<<< FAN spin when power on]

Hello so my rig contains:

MOBO: Asus z270a prime LGA1151   
CPU: Intel pentium G4560 LGA1151  <<< FAN spin when power on
RAM: Kingston 4GB DDR4 2133 CL14 288 - Pin UDIMM
PSU: Corsair RM1000x   <<< FAN spin when power on
GPU: MSI gaming rx580 x 6, but I just plug 1 and the MOBO just can not boot.
SimpleminingOS USB

So I assembled my first rig, connect  the PSU with the MOBO, both 24pin and 8pin, RAM on the A2 slot, CPU on the right direction, CPU fan plugged in and run well. Everything seems good, but the MOBO just can not boot. I power it up and just see the LED on, the CPU fan running, nothing happen on the monitor.

So I check the 4 LEDS, only the DRAM Led is on, and then I tried to press MEMok button, it does not help, the Dram Led flash, and then still on, which indicate that there is an error.

I tried to Google for hours, it seems many people have the same problems, but no one can have a solution.

So guys, you are my only hope, or tomorrow I will need to go to retailer to check it up.

[However I have a question]

Hey guys, so with the surge of LTC price, I have more than enough fund to start my own mining farm business, my 80 L3+ are coming on July and I am very excited, I know it is risky considering the upcoming difficulty, but since all the capital came from the trading profit I made with LTC, it is like risk free business for me. However I have a question which is pretty important but I can not find any real answers on Google. With the size of my farm, should I register as a company? Considering these pros/cons:

Pros:
1- Peace of mind, no need to worry that someday the government will close my farm for unregistered business operation, and easy to expand my farm size in the future.

Cons:
1- Bitcoin is not accepted as a currency, as well as they do not incentive people to trade or store bitcoin, but it is not prohibited, so it maybe hard to have the business license
2- The heavy tax for business profit, it is about 20%.

Just for reference, my electricity rate is about 0.085$/kwh, my renting fees is free since I use my own warehouse.


Thank you so much for your help.
