If there are errors, many errors are acceptable?

Not a single error is acceptable. Even a single error you have, chances of system failure. It is entirely up to you to decide whether to accept this memory error or not. It depends on how important the system is faulty memory module installed.

Chances of getting proof errors, while the memory of other factors, such as video cards, processors, mother board components like the chipset, etc, these factors change with the same test component and give a better idea of identifying the error-prone component.
