A: ICERIVER would not deliver any firmware to upgrade KS3L to KS3M. Moreover, we strongly recommend from applying 3rd-party firmware or control boards that promise to raise the hash amount. You will also be suitable for returns if things aren't working as explained or if they are lacking promised functionalities. https://iceriver-ks185219.frewwebs.com/28282506/manual-article-review-is-required-for-this-article
