Voltage was tested at just a little over 240V. My power has thus far been very steady. I have a commercial power run just for my miners.

I have a LOT of xxx, I think sss too (I'm not home now where I can look, but pretty sure about the sss). Even hash boards not showing up. All of my miners were running fine - all hash boards were active - no lost chips on any of them. Until bang - now they all look like they got hit by a low level EMP!

I can give it a try on viabtc - but to me this looks like hardware at this point. If a virus/hack did this - then there's not much to do, but if Nicehash did this somehow - that's another story.

These units act like they had their frequencies on the chains/chips set so high that it burned them out - or is still set so high that they are just not able to run properly. Again, making me wonder about a virus that is running them at higher frequencies the the miner's web interface is showing - like the virus is hiding the true frequencies from the web interface.

I have additional fans on these units (to help cool them - to them point that if their own fans were not running - they might still be fine running. There's no indications that power dropped. Our house and the miners are coming off of the same transformer - they just have a feed from the transformer to a meter for the house, and another feed to a commercial meter for my miners. Nothing in the house gives any indication that power dropped. Sagged - possibly, but wouldn't that just cause the miners to drop some chips or chains temporarily? Once power cycled - especially with 45 minutes down before powering back up, that they would come back on normal?

What do you mean about setting a level in the password to keep from switching so much - I did not know there were things to be done with the password to effect anything?

I will try the viaBTC when I get home. That's one of the things that makes me question getting hacked or a virus though. My network is very inaccessible from the outside. I mean, I would HAVE to run a VPN to gain access. My ISP, oddly, issues private IPs to the WAN connection. So like 192.168.x.x, 172.16.x.x, or 10.x.x.x type addresses. So I can't use remote access software other than ones like TeamView or LogMeIn that have a host side application that links to their online systems to allow for making connections via their intermediary websites. And currently - I don't have a VPN or any of those remote access systems setup. I am careful about my computers as well - I am an IT guy, and I have (to my knowledge) not had a virus on any of my systems for better than 30 years - at least that wasn't a controlled scenario. I have no indications of any viruses on my computers in the network - at least nothing that virus scanning in finding.

The firmware has a tab in it that will scan the miner for it looks like 3 known viruses - and that is showing that none is found. But, I don't really know the virus world for miners. I would think there are more than 3 and like with PC's would be being changed and new ones being made that might evade this firmware's detection.

I'll let you know what I see with viaBTC - but I'm not optimistic - the chips and chains don't look happy before they even start trying to get and process packets - so, I don't honestly think that it makes any difference what pool I connect to at this point.

I think my issue is with the hardware at this point. It's not the amount of the payouts or hashing power seen by Nicehash that I'm concerned with. My miners chips and chains (hash boards) look like they are damaged or trying to run at too high of a frequency for the voltage they are configure for. Currently I have all the hash boards running between 8.5v to 8.8v with frequencies of 725M to 762M - and then the individual chip frequencies adjusted for ones that could not keep up with the board level frequency setting. Now they all act like the voltages are still where I set them, but they are trying to use frequencies well over 762M - causing the chips to not be able to run properly or at all and/or hash boards dropping out completely.

Again, my concern here that something has gotten on them and is actually running the frequencies higher than the firmware is configure for and showing in their web interfaces. That could explain the 25% increase in BTC payouts from Nicehash and why the hardware is having the problems it is having - I just don't know how to verify it or fix it - or if like Philipma1957 said - somehow Nicehash switching - thrashed them somehow.

Thanks.
