Anyone figured out how to turn off Asicboost on newer miners like the S19/S19J or Whatminers m20/m30?
I’ve noticed these machines don’t seem to mine if the stratum sends a version-rolling=false request. Is there a way to disable Overt AsicBoost on these models, whether it’s via their stock firmware or a custom one (I know some of those are out there)?
Appreciate any help!
You can also downgrade the s19 series to a lower version through SD card flashing but the problem their live download page isn't showing SD card images.
But you can still download it from the archive.org here below

Don't click the download instead right-click then copy the link and paste it to another tab make sure to delete the archive.org link before you enter.
Then follow the instruction here on how to flash it through SD card.
About Whatsminer it seems there is no way to disable ASICboost because I think their units don't have ASICboost.
Are trying to mine on Nicehash? I heard that the new Whatsminer units do not support ASICboost pools if you have problem connecting to any pool try to use a pool with no ASICboost or that can switch to non-ASICboost server.
Thanks all for the input.
The m20/m30 series whatsminers seem to not have anyway to disable AB. As for S19 and the like it seems that there is no way to go without AB else the older machines seem to throttle down hashing by over 50%.
Since all mining pools worth mining on support this, I assume you mean you want to do altcoin mining.
So I suggest you post this question there, not here.
There's nothing we can do with Whatsminer units have you tried to contact their support and ask for older firmware? I think their old version doesn't have ASICboost yet.
About s19 have you tried to use Braiins as suggested above? You can able to disable AB but I don't think it throttles down the hashing to 50% it depends in your tune or just use auto-tuning and let the braiins set power and frequency for you while AB is disabled let see what's the difference if you enable and disable AB.
Disabling AB increases the J/TH - so is a negative - and it's quite simple and obvious why.
AB reuses some of the hashing data already done to find more nonces.
Thus it is getting extra nonces for using less work each extra nonce.
Makes no sense to disable it at all.
