Not to hijack the thread, but I was thinking about this and desktop systems.
That is, whether folks use ECC RAM for their desktops. Also, how many crashes
might be attributed to RAM errors. I can't find the link, but I once came a
across a Google study that claimed it happens a lot more often than not.
Though, one would need to buy or currently be using a motherboard that
supports ECC. I generally use Tyan boards and most have supported ECC RAM.
Personally, I don't see the cost as prohibitive as I only upgrade maybe once
every 5-8 years.
