If the intermittent problem does NOT show up, can someone
suggest a way of determining which if either memory chip may be at
fault. Or other suggestions about what else to try and diagnose.
If you bought the machine new, it should have come with a diagnostic
disc that can identify which module, if any, has failed.
I've run the diagnostic (TechTools Deluxe) three times. Twice if found
no errors and the other times the system froze while the program was
running. I'm guessing that the problem may be heat related, but of
course, that' just a guess.
First, I wouldn't trust Techtool to detect memory problems... because it
I had a similar story, in regards to kernel panics. I was experiencing
more and more frequent crashes and panics on a daily basis. It got to
the point where I would install a fresh system, reboot, and just wait...
I tried Techtool, Diskwarrior, Drive Genius... none reported any
problems with anything, including RAM,
Invariably, the machine crashed with a kernel panic even if I never
touched a single key. I tried restoring from different backup sets, to
different partitions - and NOTHING worked. This went on for 3 straight
weeks day after day.
Until somebody told me to check my RAM again - with memtest. I was
extremely skeptical since I had the same 3 modules since getting the
machine 4 years ago.
To make a long story short, memtest disgnosed one of my 512 mods as
being bad. I still didn't believe it... but I took it out, and the
daily, hourly panics stopped.
It's been about 3 months now since I replaced the defective 512 module,
and I haven't had a single crash since. Not one.
Memtest gets my highest recommendation. It runs best in single-user
mode, and it can take quite a bit of time to finish... but it's worth
it. I let my test run overnight.

An optimist says the glass is half full.

twice as big as it needed to be.
