Dale, I have better experience with sys-apps/memtester for catching |
| 20 |
memory errors - though running it over night. You can tell it what to |
| 21 |
test. |
| 22 |
|
| 23 |
Furthermore I had one machine (an AMD Phenom II) where I got random |
| 24 |
errors though all memory tests went through without a problem. |
| 25 |
I suspected a cache coherence bug since this was quad core processor. |
| 26 |
|
| 27 |
Once, I have replaced this CPU only, i.e. with the same memory, the |
| 28 |
spook was over. |
| 29 |
|

Therefore, if you have a multi-core CPU, run memtester simultaneously |
| 31 |
(on different parts of the memory) as many times as you have cores. |
| 32 |
|

I hope, this helps, |

Helmut. |
