Re: Is ECC memory any use?

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?



Depends who's buying. Few people do anything on "personal" systems that really justifies ECC RAM, though I'm sure the exceptions are probably on this list. If you're doing any kind of business work where uptime is important, or any kind of technical work where bit flips could cause nasty side effects, it's probably worth buying the ECC, unless you're doing high-end graphics where a stray pixel won't make a difference and most of your power budget is going to the GPUs.
