Hardware memory RAM errors on server
Posted on 2010-09-16
In the old days, you used to purchase RAM that had 9 bits per byte, with one byte being the parity bit. If the system detected that there was a difference anywhere, it would immediately crash the computer and complain about a parity bit error in memory.
I recall that over the past number of years, this parity bit has been removed, and computers don't crash due to parity errors anymore.
Is this because there is another mechanism that is used to verify that RAM is good, or is there a chance that a server can have bad memory and cause applications to crash?
