instead of using salad windows gui software, can i use XMRig (with cuda upadate) to mine? (dos/cmd)
Yes, you can. Simply point the miners at the Salad pool, with your workerID and the Wallet Address. This information can all be found in your log files, if you know where to look.
Your balance will get paid into your Salad account, providing you have run the miners through Salad at least once to tie them to your account.
