I am new to this forum but thought I would reply to this thread with my 8Gb 1800Mhz CAS7 on 790FX-GD70. Below are images on stats and some benchmarks(This is not same as in my sig as this was only a test. My sig is what I use for 24/7). Somehow SuperPI doesn't recognize 8Gb ram. "Real memory" and "Available real memory" shows -1 for me no matter what ram I use at 8Gb. I tried a few brands but all where same except if I only used 4Gb then it showed correctly. Wonder why?
