No two PC's/MoBos are the same, but FWIW here's a bed time story: I had |
29 |
three incompatible memory sticks on mine which kept failing at random. |
30 |
MEMTEST86+ did not show any errors. Occasionally, a simple emerge |
31 |
--sync was enough to crash the machine and needless to say all these |
32 |
repeated crashes had started to corrupt my fs. Running out of ideas I |
33 |
decided to start removing memory sticks until I discovered that the best |
34 |
result (in terms of stability) could only be arrived at if I left only |
35 |
one 256M stick of branded memory in the box. That was despite the fact |
36 |
that the MoBo manual said you could mix 'n match memory modules without |
37 |
any adverse effect on performance... :p |
38 |
|
39 |
In case you're suffering from the same problem, check whether a crash is |
40 |
more likely if them machine is about to switch to the next bank of |
41 |
memory/swap. Mine invariably crashed most times it was getting ready to |
42 |
swap data to the hard drive, or in any case as soon as it had used all |
43 |
the memory on the first stick. What drove me insane with this fault was |
44 |
that it would only crash once and thereafter it was often good until the |
45 |
next reboot. Also, if the transition from the first memory stick to the |
46 |
second or swap space, was caused by an application engaging in |
47 |
aggressive resource usage (e.g. Opera loading font files when it hits a |
48 |
website with Chinese characters) a crash was guaranteed. Slowly |
49 |
building up to it during a large emerge session would not cause any |
50 |
crashes. |
51 |

I hope this helps. |
