It seems that Bitmain chose all the unloved tactics when you upgrade the device Z9 Mini in order to increase sales to new and more powerful miner Z9: new parties of the model, there is no option of overclocking the device.
The first batch of Bitmain Z9 Mini had a drop-down menu in the settings that allows you to overclock the device, and the equipment worked 100% stable when overclocking chips by 50%. Most buyers have this surgery immediately after purchase Asika. If without overclocking Z9 Mini issued 10 K/sol at the energy consumption of 250 Watts and frequency of the chip is 500 MHz, then overclocking up to 700 MHz the device can be easily issued for 15 K/sol, consuming only 100 Watts more. Equipment it was possible to disperse and to 725 or 750 MHz, but worked steadily, not all instances of the model.
New Bitmain Z9 Mini in web UI in the menu Miner Configuration -> Advanced Settings from the dropdown menu the Frequency we now see only one option — Balance, which is a standard frequency of 500 MHz. It seems that the company is not too bothered and simply removed the possible options in the HTML code of the page, so if you edit and add the options you want, then everything will work.
Options for how to do it quite a lot, but one of the easiest is to open the page in Chrome or Firefox to modify the code and apply the settings so that the unit will operate at a higher frequency. To do this, hover over the drop down menu, right click and select “Inspect” or “View code”. You will see that the code has commented-out option Turbo, overclock the device up to 550 MHz.
You can uncomment the option by removing the brackets at the beginning and end of the line, or just change the frequency in options Balance at 700 MHz. Just select the line, right click and select “Edit as HTML” and make the necessary corrections. When you are done, just apply the fix and you will see them active on the page. Fear not, the fix is temporary — when the page reloads, the changes will not be saved. But if you immediately, before rebooting, click Save&Apply, the changes will apply and the device will be dispersed.
Our advice is to start with a frequency of 700 MHz and test the operation of the device. You may need to manually increase the fan speed for better cooling and stability. If everything will work consistently, then you can try to increase the frequency to 725 or 750 MHz and check whether it is possible to squeeze out of Bitmain ASIC Z9 Mini a little more performance.
Operating on the 700 MHz Bitmain Z9 Mini should give the average Hasrat about 15 K/sol without any problems and mistakes in work mode 24/7. So you’re getting increased productivity by 50% while increasing energy consumption of only 100 Watts. It is understandable why the company wants users to disperse their devices.
A more interesting question is whether the new and more powerful Z9 Bitmain ASIC as simple overclocking and will he be able to accelerate as well. Perhaps Bitmain delivers from the factory already overclocked hardware.
