those are benchmarks. what he needs is somthing that will check memory for curruption.....
At school in our tech lab we have a memory testor machine hooked up to a laptop, just plugin the simm, or dimm and it will test it (pass/fail) and give u voltage and specs for it.....these are expensive machines, but any local computer repair store will have one they use, u can proably ask them to chek it for u, it only takes 30sec. And as for software testers, i wouldnt trust them
