Error-correcting code (ECC) RAM is essential for servers because it prevents soft errors from occurring.
Soft errors occur when the bits stored in a computer's RAM suddenly flip unexpectedly. For example,
alpha particles emitted during radioactive decay or even cosmic rays cause bit flips by altering the
state of the RAM.
During the May 2003 elections in Belgium in May 2003, a bit flips was suspected of causing extra votes
favoring a candidate.
In the 90's IBM estimated that in a month, one bit flip occurs for every 256 MB of RAM. If a simulation
needs 32 GB of RAM to run for 15 days, what is the probability that at least one bit flip will occur
while the simulation is running?
