I have an old MB-586TX motherboard,and was running 2banks of 2x16meg EDO Simms.I tried to up my memory using 2x64meg FP Simms,something died,the FP'sonly read 16megs, and when I replace the old EDO's only bank (3&4)read (32megs) At startup I get an error message, cache memory error, what does this mean and how can i fix it?
