Dale, I have better experience with sys-apps/memtester for catching memory errors - though running it over night. You can tell it what to test. Furthermore I had one machine (an AMD Phenom II) where I got random errors though all memory tests went through without a problem. I suspected a cache coherence bug since this was quad core processor. Once, I have replaced this CPU only, i.e. with the same memory, the spook was over. Therefore, if you have a multi-core CPU, run memtester simultaneously (on different parts of the memory) as many times as you have cores. I hope, this helps, Helmut.
