Hi,hi , iBeLink ,
please check my mining machine , is tat something wrong? is that actually means one of my board doesnt work ? i only have 3 board working ?
2nd question is look at my mining rate of DM1 is only 134.1mHz , is it normal ?
Yes, it looks like it is not detecting one of your blades. Please check that the power and data cables are securely plugged in. If you are still not detecting the missing blade, you will need to follow the Single Blade Test Guide to find out if you have bad hashing boards on the blade. You will also need the TestTool Image.
For your DM1, it looks like the PLL is being lowered due to temperature. If you can get the miner's temperature down to 35C, it should be set back to normal.
Also, please do not pay attention to dashminelover, he is spreading false information and lies about being able to control your miners.
