Not sure if you are aware but I think you may be having some issues. The web interface is not responding and I keep loosing connections on my miners.

Be cautious but my kill-a-watt tools worked when i used them for 240v as well as 120v. Most of them are made the same just a different plug for different parts of the world.

I'm having a bit of trouble figuring out your numbers.
240v x 200amps =48000 watts. 110v x 200amps = 22000watts
I get that your miners may be on 240v and the rest of the house is on 120v for the most part(the oven might be on 240v). You should never run at 100% of power ratting, 80% max.

There will always be some loss do to resistance; over the lines, breakers and each connector(plug). You may possibly have a week breaker. Breakers have know idea how much power is going through, they trip based on heat. They should trip before the amp rating, and are rated for constant current not spikes. Some of your household items also have a spike on power when turn on that could trip the main. I've noticed that my miners reduce power then increase it again when mining. If you get enough asking for more power at the same time can overload the breaker.

This may not be the answer your looking for but for others some factors to considering when starting to plan an farm such as yours.

@yun9999 or anyone else with the Sapphire Fury cards.

I have 15 of them with all the same settings (-96mv) 900/400 15.12 driver and the last one I bought won't under-volt in Windows 10. Has anyone else ever experienced this before?
This is what I have tried;
moved it to a different rig with 5 other Fury's and it will run Optiminer but Claymore will return a error saying the GPU returned incorrect data.
moved it back to the new rig with 3 other Furys and it will crash the driver in about 30 seconds of mining with Optiminer
   reinstalled windows and new drivers - same
   installed 16.3.2 drivers - same
   UEFI Bios and standard - same
moved it to a independent computer, ran graphic benchmarks on default settings and no errors - but when I under-volt it, crashes the computer.

Every setup has more than enough power overhead, running TB 85 or H81 boards - except the independent PC (supermicro server)

I purchased it at Newegg but to send it back, I believe they would test it and it would pass there tests because how many gamers really under-volt that much.

Any suggestions

I have 6 of these cards. 1150 core, 1500 mem, 15.12 drivers, Win 10, 60% fan are the best IMO. They do consume a lot of power so make sure you have a good PSU(s) and that has a good over head of power.
5 x 280x Vapors and a 7990 at these settings use 1557watts for ZEC.

Thank you

ZCL at the moment. Once I have a good amount I will switch to ZEC unless Eth jumps up in value again.

My little setup, like most always tinkering to make things better.

https://zclassic.miningpoolhub.com or http://zcash.flypool.org are both good pools IMOP.

jelin1984 As for how to connect to nice hash, YOU REALLY NEED TO READ before commenting. IT'S about 11 posts ago or the help file.

Have you set the virtual memory to 16GBs? Also, I believe 16.3 drivers are the best for 480s at the moment.

Not sure what your settings are or the cards or OS but sometimes you have to increase the power to the card that isn't as good as the others. This happens because the miner is pushing the card more it sometimes can't handle the extra demand. In windows using afterburner, increase the mV to the core. I have once rig that has six of the identical cards but there is one card that can't quite handle the under volt like the rest. So, I turn the mV up a bit for all of them and its runs rock solid. Its worth a try at least until we have more information on your setup.

Try this
optiminer -s eu1-zcash.flypool.org:3333 -u t1cCsQhjhFi8ZDbQNZB6tVEJaeBEQ1B7.swq7 -p x -m 8080

This is mine.
optiminer -s zstratum+tls://us1-zcash.flypool.org:3443 -u wallet.280bottom -p x

Thank you for V 1.6. Moved my 280x rigs over and a good bump on the Fuji's and 290's.

Try this:

setx GPU_FORCE_64BIT_PTR 1
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

Not for my Nano/Furrys it isn't!

The 1300G2 is an amazing PSU but it only has 6 6+2 pin connectors and 2 6 pin connectors, if I remember correctly.
