I have a bunch of memory sticks and I wanted to kick up my Centris to max 68MB but something isn't working right.  A 16MB SIMM shows up as 8. A 32MB SIMM shows up as 8.  I put in 2x32MB, it shows a grand total of 20MB (4MB onboard plus 2x8MB)  I tried mixing and matching and I tried one at a time in either slot.  It seems to be always 8MB if I used anything larger than 8MB.

CPU problem? or where to start looking for trouble?  Right now it's like a Porsche that is limited to top speed of 20 MPH because it won't go past second gear.
