Overview of PassMark MemTest86

The number 86, following the MemTest part of the name, refers to the original x86 CPU instruction set that all of today's PCs use. This covers both 32-bit and 64-bit machines. (So there is no need for a future product called MemTest64).

Unreliable RAM can cause many problems: corrupted data, crashes, and unexplained behavior. Insufficient RAM is one of the most frustrating computer problems, as symptoms are often random and hard to pin down. MemTest86 can help diagnose faulty RAM (or rule it out as a cause of system instability). System builders, PC repair stores, overclockers & PC manufacturers often use it.
