i have a 3and a half year old pc.i have a msi motherboard which supports 256mb ram maximum. ihave 2 slots. since adding another 128mb to slot 2 it is not recognized. both 128mb work in slot 1. my moterboard came under the heading on the msi website as a slot 1 motherboard. does that mean i can put my maximum 256mb in the one slot. thanks.
Have you tried using memory in slot 2 on its own,if so and it wont recognise either stick then it is the slot that is the problem. If it does recognise both sticks of memory then it means your 2 sticks are incompatable.
