ECC does not protect against Rowhammer attacks.

It seems you are correct, but surely it must make a practical attack much harder?

I'm not so sure. But it's not an area I know much about. But practically thinking: If you try to change the memory content of an area, that means you have software running on the target machine. Does it matter much then whether you need more time because of ECC?
