pc133 ram in pc100 mobo
My wife has an AI61 Shuttle recently upgraded to Windows XP. Added more RAM up to 3 sticks of 128MB for total of 384MB RAM. Tried to get a little more so I popped in a 256MB stick of PC133 along with two others. Bottom line, it doesn't recognize any more than 256MB RAM. Has anyone else had this trouble. Is there a chance I would do better with 256MB PC100 sticks? The manual says it can take 3 sticks of 256MB RAM for a total of 768, but I can't get any higher than 384 with the 128 sticks, or 256MB with any combination of 256 sticks along with others. Some of the 128 sticks are PC133.
