ECC doesn't solve rowhammer, but it raises the difficulty.
If you only get a single bit error, ECC will fix it, and increase a counter / raise a usually slow interrupt, if you get a lot of them, perf will be impacted, and the operator should notice.
If you get a double bit error, ECC will (generally) halt the os, and the operator will definitely notice. -- you won't get to try very much.
If you get a multi bit error, maybe you can do your nefarious task.
