I had a control board go bad, and so I replaced it, flashed the new control board to the antminer recovery firmware, and proceeded to install hiveon, and started mining. I literally did nothing else. A few hours later I remember that I forgot to autotune it to 504mh/s @ 660 W. Welp, to my...

Thanks for the reply. I like rackmount stuff. Unfortunately, that device doesn't seem to offer much surge protection. According to the description: Another thing that I worry about it is that it has standard NEMA 5-15R receptacles. I know I can take my 120/240 stuff over to e.g. Europe, and...

I installed a 240v/30a (USA) breaker and cable, and decided on a 20a pdu. At the time I purchased, I didn't realize it has no surge protection, like most PDUs, so I got an over-voltage relay (not a true surge protector) as a better-than-nothing solution, while I decide what to do. The cheap...

In my search to find a solution that does not involve bolting two cases together, I came across this HSF. It's from a British company, and is not sold via the usual channels in the US. I checked to see what, if any, limitations exist in terms of cpu wattage, and couldn't find any, which...

The 4U version of the case is over 1000 USD used, and the other case I could find w/ 24 hotswap bays is nearly as much. I bought two, and would rather not buy a third. Thanks for the input.

As the title suggests, I want to bolt two of these together, such that it essentially becomes a 4U case. Before I get into what I have in mind, I'd like to explain why I want to do this, in the hope that someone comes up with a better solution that I haven't considered. The case is designed to...

I've not, but I maintain a lot of servers, cheap renewable power, and have a good understanding of electrical circuits. Just seems like a natural extension. Googling innosilicon is not encouraging.

Edit: The choice seems more like buying from alibaba or not mining, and I definitely have not ruled out the latter.

I would gladly do that, but there is no stock of anything. Only the S19J is even displayed on their website, and no way to preorder it. The date is tbd, and I suspect when the batch arrives, it will be bought up by large farms ordering dozens.

It's surprisingly hard to find testimonials about buying antminers from China. The information I do find tends to be old. It's a bit unsettling because I'm about to drop 5 figures on antminers. I know to use trade assurance and deal only with verified buyers, preferably with many years on the...
