Hey all. I ordered 4 units and 1 of the four units 8 asics never init; they are not over clocked. Ive had my fair share of running S1's so was used to the occasional reboot to resolve asics that drop offline. However these never come online and I've rebooted so many times I'm just ready to send it back for replacement.

The question i have is, how long does it generally take to receive a response back from bitmain? My initial question was sent to them using the website form over at bitmaintech.com on july 30th, and also another message sent on august 3rd. Im starting to worry at this point, thus me questioning the forums. Has anyone successfully submitted an RMA request and have any comments from experience on the process in general and how long do things take to get moving and to receive replacement?

In my experience, sometimes they respond with in minutes or hours.
Sometimes even take days and other times never respond to email and pm.
RMA also takes out your precious time earning BTC.
Try to solve the miner issue yourselves as much as possible.
If you go back in this thread you can see the guides to trouble shoot.
In your case, if you are using a sufficient power supply then thermal paste may be the issue.
Unscrew the front heat sink and replace the thermal paste with a new thermal grease of above 3 thermal conductivy.
