Ive noticed recently that my computer has a slower response time for doing just about everything; opening folders, applications, even games are somewhat laggy.
I overclocked my ram to the advertised spec of 3200 and I overclocked my TR-2950x for all cores to 4.3 about 6 months ago. Temps are in the good/great range ~30c idle, 55c under load. I haven't tried taking the overclock off just yet because I am trying to see if it could be something else.
