Google Finds DRAM Errors More Common Than Believed
An anonymous reader writes "A Google study of DRAM errors in their data centers found that they are hundreds to thousands of times more common than has been previously believed. Hard errors may be the most common failure type. The DIMMs themselves appear to be of good quality, and bad mobo design may be the biggest problem." Here is the study (PDF), which Google engineers published with a researcher from the University of Toronto.
Parity is different then ECC. Parity allows the system to detect, but *NOT* correct errors. ECC however, detects and corrects errors. Unless specified, all consumer desktops and laptops contain standard memory (non parity or ECC).
Life is not for the lazy.
