I have a K6-2 533mhz that I am trying to upgrade to 256sdram from it's stock 64sdram. The new stick is a 256 133mhz sdram dimm... goes in original slot no problem, but when restarting computer... mb ram amount clicks away in upper left hand corner of screen up to 120mb, then screen changes into a mumbo jumbo of patterns and stays that way. Have tryed reinstalling only to have same outcome. Original memory will work just fine when reinstalled. Bad stick?????? What am I doing wrong??? Help!!!
