HEX 16A and Hexminer problem

[braindead]

Anyne here could help me starting with 16A boards ?? I´ve connected 3 boards to a PSU 300W, when i turn on the PSU they start working and computer detects them well on usb, my problem is with HEXminer, i can´t push the voltage on the chips more than 1V also when i press start i won´t get any numbers on the program, it seems to be running but i won´t get hash speed etc etc, no values ... something i must do on router ?? or

have u tried 1 at a time?

dont think a 300w psu will cut it, especially if its an unbranded cheapo one that probably puts out a lot less than the claimed specs.



make sure your com port is set correctly in hexminer, I had the same issue as you when the com port was wrong (not the voltage issue)

Yes it´s an unbranded old PSU with 300W , im now testing with only 1 unit and results are the same

The com port is 100% correct

Looks like a power issue, if you look at the chart I posted above the min voltage at default clock speeds is 1.2v.

Perhaps your PSU doesnt have sufficient amps to power the miner?

Don't forget PSU's don't put all their power on just the 12v line.
So 300w is not like you can connect up to 300w of equipment on the same voltage.

Besides that, usually the indication on the PSU is a peak and not steady (much like watt on a speaker, 1000w peak, 20w RMS)

Just a random image I took from google:

You can see here it's a 580w PSU but it only has 420w on 12v

Just try them 1 by 1 and see if they work. If you hook them all up and they don't work, it's quite assumable it's your PSU

Problem was on the PSU

Many tks to both of u for helping
