About firmware versions and overclocking:

I've been doing some serious digging!!!

When you login to your Z9 mini you check on first page "System - Overview"
Batch 1, 2 and 3 all seem to have
"Hardware Version:" = 9.0.0.5

"File System Version:" tells you which firmware version your Z9 mini is running on.

There are at LEAST four (4) different firmware versions for z9 mini:

1. Sat May 26 20:42:30 CST 2018 = Antminer-Z9-Mini-201805262047-500M.tar.gz
2. Sun Aug 12 17:43:41 CST 2018 = ? ? ?
3. Thu Aug 30 14:57:48 CST 2018 = ? ? ?
4. Fri Aug 31 17:02:59 CST 2018 = Antminer-Z9-Mini-NAND-500M-201808311812.tar.gz (the now only downloadable fw on Bitmains site for z9 mini.)

May 26 and Aug 12 firmware-versions are overclockable either from SSH into machine and changing the file "/config/cgminer.conf" or from Chrome using "Inspection" for the field where you choose "frequence" (May 26 version) alt. "mode" (Aug 12 version) on page "Miner configuration - Advanced settings" and for the May 26 version ofcourse you just choose the frequence here you wan't just like God intended !

Aug 30 and Aug 31 versions just ignores any frequence value from cgminer.conf or with Chrome's "Inspection" method.
If you go to the "/www/pages/cgi-bin/minerAdvanced.cgi"-file and changes value and saving (after you already made the filesystem writable). After reboot it will have changed the file back!!!

Batch 1 seem to be very overclockable !!!
I, myself, are running my single batch 1 Z9 mini on 768 MHz and it's solid !!!

For Batch 2/3 I have seen quite a few running them on 668 MHz solid with both fw May 26(after upgrade) and Aug 12 firmware's !!!

WHEN you install(upgrade) the May 26 firmware using the page "System - Upgrade" I strongly recommend you UNcheck "Keep settings:" to get as clean install and as little problems as possible.

I really recommend you checkout mining at prohashing.com dispite their "high fee" (not high in relation to what I earn compared to MPH, nanopool and flypool after 48 hours, at least for me and my friends.) Read under "Help" on prohashing.com for further info and earning possibilities if you choose a single coin to hash.)

Howto - Pool settings for prohashing.com: (here you can see mine)
Url : stratum+tcp://prohashing.com:3336
(3336 is for Equihash algorithm that z9 mini calculates)
Worker : imine2
(imine2 is the username I choose to register with at prohashing.com)
Password : n=z9mini101
(I choose the name z9mini101 where the "101" stands for machines ip:10.0.1.101 in my home network and it's just a name to identify your machine for yourself and prohashing.com. Important for them and you if you have more than one machine being able to distinguish each machine.)

May 26 firmware:
File: Antminer-Z9-Mini-201805262047-500M.tar.gz
sha-1: 8791eee569dfff728c8363e5d8fd93f68957a2ee
