Sandpoint & random crashes?

Another possible hardware related problem might be that the Dink monitor is not
programming the SDRAM controller with the right parameters for that DIMM module ( I assume
the sandpoint uses DIMMs ).
I'm not sure if the monitor reads the param data from the module's eeprom or is manually
configured and stored in CMOS ram.

Anyway, have you run any memory tests?

My 2 peso's worth, good luck.
