Has / can anyone here share some accurate readings of current draw (with stock voltage settings) of these moonlanders.
I have a pluggable 7 port USB 3.0 hub, this one:
https://plugable.com/products/usb3-hub7bcIt has a 60W power supply.
I have 5x moonlanders connected to it running at 756 clock speed and it has a reading (at the main socket for the hub alone) of 53.08W which seems wayyy to high.
I saw in the OP that these should use 1.3W per hash. Now for a 756 clock speed, this gives 4.278mh (which is what i am seeing) but then a watt usage of around 5.56W (current draw calc to be 1.11amps) and if I have five of them this should be around 33watts but i am actually seeing nearly double at 53watts. I know PSUs are not 100% efficiency but thats too much loss - something isn't right.
I guess what would be mega useful is a full rundown of all the clock frequencies and the current for each one like:
Clock
384
450
480
540
576
600
612
625
636
648
660
672
684
700
720
744
756
768
796
832
852
876
900
924
954
anyone fancy trying it?
It would be really useful as this would allow more people to get stable frequencies depending on the device they where connected to (I was hoping to try one connected to a Pi3 usb port but that is limited to 1.2a max total).
Stock voltage for both controllers is set higher than they need to be...to achieve the low end in current draw your going to have to turn the voltages down by quite a bit. Also not sure how your measure current draw, but my figures are from the 5v line. If your using a small 120v to 5v converter, those things are super inefficient. Your probably drawing an extra 20-30% using stock voltage settings, plus another 20-30% loss on the small power bricks so 50w for 5 at the wall sounds about right.
Also don't forget that if your drawing 50w from a 60w converter that near its max, and efficiency goes down even more.
