The standard for memory diagnostics
- Boots from a USB flash drive to test the RAM in your computer for faults.
- Utilizing algorithms that have been in development for over 20 years.

Unreliable RAM can cause a multitude of problems. Corrupted data, crashes and unexplained behaviour.
Bad RAM is one of the most frustrating computer problems to have as symptoms are often random and hard to pin down.
