When being referenced by the CPU, they will cause the system to crash (if an error occurs in a region that cannot be recovered) or recover other systems (for example, if an error occurs in the group memory [MEMD, cyBus Complex will be restarted ). When a soft parity error occurs, you do not need to switch the motherboard or any components. Www.2cto.com hardware parity error ----- A hardware parity error occurs when a chip or motherboard failure that causes data corruption (not a bad thing at all times or most of the time. In this case, you need to restart or replace the affected components, usually memory chip swap or motherboard swap. When we see multiple parity errors on the same address, we say there is a hard parity error. There are also more complex situations that are more difficult to identify; but normally, if we see multiple parity errors in a specific memory area in a relatively short period of time (several weeks and months, it can be considered that a hardware parity error has occurred.
