Do you use ECC RAM? Do you have any data about failure rates?
I'm considering getting a system with 8GB DRAM, &
"Tests[ecc]give widely varying error rates, but about 10-12upset/bit-hr
is typical, roughly one bit error, per month, per gigabyte of memory.
In most computers used for serious scientific or financial computing and
as servers, ECC is the rule rather than the exception, as can be seen by
examining manufacturers' specifications."
So, for that comparison 8GB DRAM is about 8 errors per month, ie about
one per 3-4 days.
What rates do you have?
