I have knocking in my 2005 Accord V6 as well. But only in the 2200 to
2800 RPM range when climing a slight grade. Could not reproduce it for
the dealer (totally flat terrain near them) so have not been able to get
help from the dealer.

This only is really bad on one short stretch so I just go slow to keep
the engine at about 2000 RPM (neither I nor the people behind me are
thrilled).

As already stated: the lifters should be affected by RPM (more RPM =
more noise) but not by throttle. And noisy lifters make a clicking or
banging sound, not a pinging / rattling-ballbearings sound.
