Fix the wallet, please https://www.virustotal.com/#/file/880d5e0d92c85069a440a9abd6cae9e27c4e4c06dd0cac4f9de6acf4b117788a/detection

Hey. I tried to install a wallet from the official site. received at downloading a file in .rar. before installing, checked for viruses ... and there bitcoin-miner and trojan. can comment on the situation?

After the difficulty bomb last week ZEC has been a good 30% more profitable than ETH to mine.

This only matters if you are immediately selling the coins. For some reason people think that if they mine the coin while its most profitable they make more. This is absolutely not the case is the only number that matters is the price when you convert it to something else.

Then, of course, there are the people that just throw their money away using nicehash because they are too lazy to convert it for themselves.

I had same problem, and it has to do with PSU. Make sure you connect pcie/vga power cable to your GPU. So it provides enough power to run them.

I run my 5 1070s at 75% TDP using MSI afterburner.  For my particular Asus 1070 strixs that means they are running about 120 watts to 130 watts per GPU.  Did you undervolt or are you at the stock TDP? 

you didn't list your motherboard, but I've heard that enabling the 4G in the BIOS is required once you get past a certain number of GPUs.  What mobo you using?

What wattage is your power supply?  I run a 5 GPU 1070 rig and use two 750W power supplies.  I've got a bit of a power cushion but planning on getting another GPU if the prices will ever come back down...

You shouldn't be overclocking memory when using this miner/algo. Turn that shit all the way to -502, the core clock is whats going to add Sols/s
