Thanks for the link.

I haven't seen anything after 375 iterations (600s). So I may still be exploitable, but that means you'd have to keep something running at 100% CPU for > 600s and somehow have me not notice the laptop fans going crazy.

An exploit tool could always run slower and hide from that.

Also consider that it might work better when your laptop is in lower power mode because of reduced voltages.

You may wish to try both single- and double-sided hammering. If you hit the right row size it is significantly more effective:

How long did you test it? The tests they did ran fairly long, possibly you'd have to run this for days to really be able to state that a particular machine/ram combination is not vulnerable.

No x86_64 support?

They mean no powerpc or other non-intel chips. I've run it on several x86_64/amd64/x64 processors.
