How can you tell if RAM is defective?
I recently upped my RAM from 8 GB to 12 GB. System Profiler shows I have 12, and I ran the Hardware Test, and it didn't say anything was wrong. However, since installing it, it seems if anything, my computer is running more slowly, especially my Safari. Would I not be able to tell the difference in speed of windows opening, functioning of programs, etc?
