Innosilicon A9 Overclock / Free / No license needed

A9 Overclocking guide, free, no need to go to pay someone for finally finding this themselves.

This information has been available for since March of 2019 and results in 60-70kSol/second on an A9. Credit to Sto1cNate @ Discord for putting this together.

Bellow you will find detailed information about overclocking the A9 using the October 2018 firmware.

[2:19 AM] Sto1cNate: So, this is how this works for the October firmware and why it is superior....
[2:19 AM] Sto1cNate: You do not set the VID at all. Voltages are set through a fixed VID table in relation to the frequency.
[2:20 AM] Sto1cNate: Clock frequency of the cores are 100% set by the PLL setting in a 1:1 ratio. Ex: A PLL setting of 1500 = 1500MHz.
Maximum PLL setting is 1596.
[2:22 AM] Sto1cNate: Here is a canned copy paste you can modify (ONLY WITH THE OCTOBER 2018 FIRMWARE).
DO NOT PASTE THE FOLLOWING INTO YOUR CONFIG FILE! Paste it directly into your SSH terminal after logging into the A9 and have the # prompt.

Code:

#Edit the pools before pasting
#Copy and paste this whole block of text after making desired edits
echo -n \
'{
    "pools": [
        {
            "url": "stratum+tcp://na.luckpool.net:3060",
            "user": "znhGeka9zXmixvw6ufzGpcaSXcSACrjx5WZ.A9-XXX",

            "pass": "x"
        },

}' > /config/cgminer.conf
echo -n '{"mode":"performance","level":"4"}' > /config/profile.conf
#The miner must be rebooted for the new configuration to load

[2:27 AM] Sto1cNate: The above configuration on my test A9 results with using ~18.45 amps at 12.0 volts per card.
WARNING!!! At that current level, you need to be using a power supply with 16 gauge cable.

[2:28 AM] Sto1cNate: That is a total system power of roughly 664.2 watts without adding in the additional power from efficiency losses.
704 watts from the wall if running at peak efficiency on a 94% rated PSU.
Solution rate per hash board was between ~21 KSol/s and ~23 KSol/s.
Depending on board quality, should provide a total solution rate between ~60 KSol/s and ~70 KSol/s.
Sol per watt efficiency would fall between 90.3 and 105.4.
For reference, the A9++ has a Sol/w rating of 90.3 and the Z11 has a rating of 90.5

[2:33 AM] Sto1cNate: Here is another handy copy paste to enable full privileged access to the A9's API.

Code:

#Copy and paste this whole block of text
#Make the filesystem writable
mount / -o rw,remount
#Modify cgminer service unit file to enable API access
echo \
'[Unit]
Description=sgminer4a9
After=network.target config.mount

[2:33 AM] Sto1cNate: NOTE: I have deleted a few of my earlier posts as I was experimenting and don't want to add to any more confusion that is scattered all over this channel.

If you do not have the A9 October firmware, you can download and install it by just changing the clock on your computer back a couple of months which will bypass the limitations and upgrade checks that innosilicon put in place.

I can make the A9/October firmware available if needed.

PM me for questions.

Thanks,

Jason

So I guess we are on a non truce again ....Well the mod I offer is different then the config file mod and can be found at the link below

Just editing the config file will get you about 60-61k only where my firmware will go much higher 65+k steady average with peaks over 80k. The mod you posted max 1596m where this is mine....

https://bitcointalk.org/index.php?topic=5132758


chip0 set pll 302(912MHz) -> 385(1725MHz) 1725 ...thats not just 1596mhz plus other choices for speed.

Depending on board quality, should provide a total solution rate between ~60 KSol/s and ~70 KSol/s.
... I'll quote this from the post above. This has been long proven since March.

Have a nice day.

I am not going to go back and forth with you get over your cry baby crap. You didnt want anything to do with the A9 now you want to be all up in it. So if the board quality is good then you should get 65+ k no problem with my mod. There was a lot more done with it then you think.

Digging a hole, filling it back up, digging it again, filling it back up is also more work than you think... but completely unnecessary.

Lets see the screenshot of the over 63k then I might consider your comments but so far everywhere it only talks about 60-61k is the most average people are getting with peaks higher with my mod you get 65+k average with peaks as high as in the 80k range. Show me any 24 hr stats higher then this

[efudd]

Apparently you reported me correcting your grammar. Lol.
