Is ECC memory any use?

[Roopnarine, Peter]

First, apologies for the top posting. On the road, and using my company's
stinky MS webmail.
But, ECC memory is absolutely a good idea if you're performing a lot of
RAM-intensive operations, such as in numerical simulations and so on. Error
occurrences are infrequent, but of course will increase in frequency as
memory access, and the amount of memory in the system(!) increases. So if
you're at all involved in that sort of work, then ECC is worth the minimal
effort of use.

I'm getting memory for a very old (P2B-LS) Asus motherboard,
and I see I can get ECC memory for some 20% more.

Is there any point in getting this?
I see there is quite a lot of work
in getting ECC testing incorporated into the Linux kernel.
But even if it were there, would it be very valuable?

I have a feeling that disk errors are far more likely
than RAM errors.
Is that right?
