I doubt it.

It's "well... I don't see any errors. Duh." or
"my work is not valuable enough" mentality.

OTOH, I never had any data errors (that I know of) until I bought the
ASUS K8V Deluxe in 2003 with ECC memory; this worked mostly, but for
some things (in particular, having to do with USB, but also often when
unpacking a Linux kernel) I got wrong data (without error messages or
anything). I returned the motherboard, and got a K8V SE Deluxe
instead, which does not have this problem (it still has a problem
booting 64-bit Linux, but I know a workaround for that).

So, while ECC may reduce the probability of data corruption, it does
not eliminate it, and the other sources of data corruption may be more
significant than RAM errors. Still, for our servers, we require ECC.

the machine occasionally shuts down to protect northbridge
from
overheating under load (x86memtest would do it).

You could try to change the airflow in your box to address this
problem.
