As to the guy with the bad PSU. Try removing one hash board at a time to see if it turns on. If it detects a short in any of the boards it won't function and will throw up a fault light. Also, if it's not inserted all the way properly it'll do this.
Remove one hash board at a time and try turning it back on. Do this in a well ventilated room, as the bad hashboard can give you quite a light-show of arcs and smoke if it burns out.

how many X3 units have BA shipped? I have yet to receive my unit.
Its from the Miner Operator software that BA provides on their website:

You run it on a PC that is on the same subnet as the miners. It will automatically scan the network and it'll find the devices, from there you can choose from the dropdown menu in the bottom right corner of the software different options for the devices.

Well that's new! Have you done any tests with lower voltages? That could really help people out if the efficiency can be improved.
I haven't tbh, but when I upped the voltage from 0.81 to 0.85 I noticed a significant drop in the errors count on all 4 machines. Also there are quite a bit options offering different voltages all the way down to 0.5v. The max is 0.9v

Its in the Miner Control Software. Will post a screenshot later today if you still cannot find it. Cheers.
I'd like to see it. I don't have access to the software.

The voltage can be adjusted with blackarrow's software. Just tried that on my X3 miners and it works like a charm.
Never seen that setting. Got a screenshot?

After 15 months they sent me an X3 with a dead PSU. Thanks BA!
Just managed to get 2 x new back plane and 20 x new hash boards from BA and after a a days work of taking all the heat sinks off the hash boards and then put the two back planes in and managed to make 5 hash boards to test.
The 2 new back planes both don't work, they just turn on and then the fans spin at max RPM.
I tested the 5 other new hash boards I made with one of my other X3's with the back plane it came with and ended up 2 of the 5 hash boards did not work.
Thanks BA.

Could you have underclocked it more? How is the noise level at those settings? I can't find a proper review of these anywhere...
They don't adjust voltage, so they're 1 J/GH at all clockspeeds. Noise-wise they're quite loud.

I am still waiting for my refund 
The 800/1000/1100/1200Mhz setting seems to be the speed of the controller, not the hash boards.
I've not seen inside an X3, but the X1 uses a Rockchip RK3186 SoC, and these speeds match.
That's odd, because the hash speed did go down when I switched from 1000Mhz to 800Mhz.I've not seen inside an X3, but the X1 uses a Rockchip RK3186 SoC, and these speeds match.
So I'd hope there was some better way to increase efficiency of the hashing chips.
Maybe one can ssh into the machine, but I haven't tried this.

The only options available on the web interface are 800/1000/1100/1200Mhz. The higher I put it, the more errors I see.
Don't expect a review, they are not worth the effort anymore.
A X3 produces ~us$1.8 a day at current difficulty while using ~20kWh (@230V) of electricity per day at the lowest offered speed.
BTW, the VAT invoice also came in, another us$200 down the drain.
