These are EEPROMs on your memory modules, not sensors, so it's expected
they don't show in the "sensors" output. Use the decode-dimms.pl script
if you want to decode the contents of the EEPROMs.

This is a rather rare chip, and easily misdetected (see the low
confidence value). So I don't think you actually have this chip, and
you shouldn't load the lm92 driver.

Please provide the full output of sensors-detect from lm-sensors
2.10.3. Most likely the sensor chip is too recent for the (relatively)
old version of sensors-detect that you used, so it didn't find it.
