weird stability issue..

Recommended Posts

What does it mean when you can dual prime 16+ hrs without errors (small fft's) but 1 core fails within 45 minutes when you do a custom blend (850mb memory tested on each core) am I stable or not...

Selecting Small FFTs runs the data in the cache of the cpu. The cpu is stressed with very little main memory accessed. In-Place FFTs places the data in the main memory. One section of memory is used throughout the test. That section of main memory, the memory controller and the processor is stressed. Blend also places the data in main memory but since the FFTs very in size all the memory is accessed. It also stresses main memory, the memory controller and the processor.

 

If you are passing Small FFTs but failing Blend it indicates instability with the memory controller or ram.
