Given the chipset you have (430VX) - no. ECC is only supported by
the 430HX for Pentium motherboards. All the Pentium Pro chipsets
support ECC though.

ECC is just parity RAM, the memory controller in the chipset detects
single bit errors and recalculates the correct bit.

In my experience, parity (ECC) memory does seem to cure some strange
problems, or prevent them from occurring. You may run a machine
on non-parity RAM for a long time without problems, but when you
have an office full of development machines the productivity lost
by just one or two machines suffering bit-rot justifies putting
parity RAM in from the start.
