I have a PII-400 Dell Latitude CS. What kind of sodimms do I need? I stuck in a PC66 SODIMM and it works but I'm wondering if it's possible that the memory is running out of spec. Can sodimms be made to perform out of spec like regular desktop DRAM? for example, can PC100 sodimms be used in 66mhz FSB laptops? can PC66 sodimms be run at 100mhz FSB?
