For you two I agree. When I had popped in, I was wondering if something was hinky with the batch of units. In my case it turned out to be a memory error that memtest picked up (and rosetta) but prime didn't. I reset the memory per Kingston specs and so far (15 min.) it has gone beyond where it failed before.
if i ran memtest on me, I'd fail.
