THE REQUIREMENTS TO USE THE NITROUS RELEASES ARE:YOU WILL NEED BETWEEN 1100 AND 2100 WATTS Of POWER....
YOU WILL NEED GOOD COOLING THE UNIT WILL RUN IN THE HIGH 80'S TO Low 100'S when ran @825m (About the same way a D3 runs overclocked temp wise) I ran my unit as high as 105c for days now without a problem. Apparently it wasn't past Bitmains thermal throttle. I believe these units can handle up to around 120C I wouldn't push past the 107 to be safe.

--- BTC--- 3JRKnuhtvC9oqW2rDDWq6EwQBES9SPWKsd*** Updated 5/13/2019 14:36 CST ***Release v1.5 Chipless Nitrous Public with speeds 153+ k/sol. I am going to giveaway the speed of about a Z9 Mini for free basically with my release.Files are factory or OC versionsSD card files updated on 4/25/20191 Unpack files from zip to a sd card from 2gb-32gb in size.
2 Power down miner and place sd card in sd slot on miner
3 power miner back on and wait until you see the led's flash or wait about 2-3 minutes
4 power miner down and remove the sd card
5 Power miner back on and SSH is enabled and there will be no signature checking for future updates thru the web gui.
Your machine is now ready to load any custom firmware and controllable via ssh
Z11-SD-SSH-NoSig-04232019 Factory:https://drive.google.com/file/d/11-OaCaNMoff3lt4QFznb_a79T291qy12/view?usp=sharing** Upgrade Current Firmware if you already have SSH and Signature Checking disabled **WARNING the overclocked over voltage firmware may require you to set the fan manually to 75% or higherUpdated 05/10/2019 1:43am CSTThe Z11 base firmware is the 04/23/2019 version from Bitmain,the scan frequency and default frequencies have been updated and the voltage was increased. After about 10 minutes of running the machine will scan the frequencies every 2 minutes or so. Takes about 1 hr to reach full speed with the Z11's
SSH is enabled as well as malware protection against .antminer malware. The hash increase in about +3% increase over the factory firmware.
This is time consuming and I do lose profits from the miner during the coding and testing time, so if you find this helpful please make a donation. So far only 1 person has made a donation, if there are not more then this will be the last public release. I lose money during testing and coding, last week during testing and tweaking my machine was up and down which caused my overall hash to go from 480 to as low as 350 which isn't good for me money wise. I use my own machines unlike efudd who has others test his releases.
To install goto the upgrade screen and upgrade as usual. The machine must have signature checking disabled before you try to upgrade. Older....But stable v1.0 Beta 3 about 1800watts
https://drive.google.com/file/d/1uMtatkGLtzCsEQin2ccHKS188-HRsFb2/view?usp=sharingUpdate... v1.7 5/30/2019 2:38 CSTYou will need as much as 1900 watts to run this file right now. Apw7@220v not APW7@110. If you are running 110v then you may need 2 power supplies to run this file.
*** Important After upgrade you must select the settings first and then apply your frequency choice to begin.
https://drive.google.com/file/d/1j_m9p8ApxFC27IYoCis2AR1FK1q6Ge7V/view?usp=sharing**Changes from 1.5 and v1.7**Added user frequency control Limit is 775m for the public version Paid version is 825m
Added Low and High Voltage for each frequency
Better power efficiency
Fixed a couple other issues
**Option still to fix - On reboot the miner must reapply the frequency or it defaults to 731m
this only effects a full reboot and not a change in frequency. The unit will scan for 2-20 mins
while it does some checking and full speed should be reached in a few minutes to about an hour.
