No, I think they'd interact differently. The interaction is
``reporting errors'' I guess. I think each major memory controller
family has in the past needed a separate driver.
The solaris memory scrubber might also be described as interaction,
and it is afaict silly on AMD because there is a hardware scrubber
which is additionally able to scrub the L2 cache. I don't know if
intel has a hardware scrubber so there is another potential
difference. Scrubbing may be silly period, statistically: you are
betting the exact same row will get hit twice with an error rate of at
most once/month seems implausible, but I still like the idea because
I'm interested in spotting bad ram or dirty connections more
deterministically instead of having to put ``memory load'' on the
machine or something.
definitely worth sorting all this out somehow instead of just paying
and hoping! sorry I do not have real answers.
