Indeed, but we're talking about you as the buyer here, no rush to leave feedback. I don't rush to leave it myself.
I've still had RAM test fine that ended up faulty, with RAM generally many of the components are right on the edge of treading on each other's toes so it doesn't seem to take much to push it over the edge. I only found the RAM was faulty by swapping it with some good stuff and swapping back, with the fault following the suspect stuff.
