: For gaming systems, 3 to 6 hours is often considered ample, though extreme overclockers may run it for 12 to 24 hours to ensure total rock-solid stability.
Unlike the free version of MemTest86 (which stops on errors), Karhu provides continuous feedback. If an error is found, it logs the address, the expected value, and the actual value immediately, allowing you to adjust timings or voltage on the fly without restarting the test. karhu ram test 1.1.0.0 download
If you are a casual user running memory at JEDEC stock speeds, stick with the free tools. But if you are chasing every last nanosecond of latency or squeezing 6400MHz out of a 5600MHz-rated kit, and never guess about memory stability again. : For gaming systems, 3 to 6 hours
