-Without the flag, patches `0009` and `0010` are not applied at all and nothing touches the PLL. The multiplier is compiled into the modules, so changing it means re-running `install.sh`. In a mixed 8GB+10GB box the same multiplier lands on every card, so check each one with `sudo ./verify.sh` before trusting it.
