I previously had two 64 MB SDRAM in my only two memory slots. Today I got a 128 MB SDRAM chip from my friend. When I installed one 64 MB and one 128 MB chips, the system however detected 128 MB RAM only. Both are 133 Mhz and 100 MHz compatible RAMs. I have prevoiusly also tries combining 64 MB and 128 MB slots. That was successfull. If the system is not compatible with 128 MB chip, then it should not detect it all. Why is it detecting only 64 MB? Please help
