Simple answer is no. They are two different types of memory and unless that motherboard can take different types, it will not fit in.

Also to throw a further cloud. Are you using a 64bit operating system for the 4Gbof ram or does it have onboard graphics because wndows 32bit has a total limit of 4gb.

Im using xp home which i think will use all the memory,how do i tell if its 32 or 64 bit thanks for a swift reply

If it helps i did a crucial memory scan and the memory was compatible so i ordered

'or does it have onboard graphics'

Makes no difference. The 4GB has to include ALL system memory.

Pine man thanks for replying i have a nvidia graphics card my motherboard is a rio(packard bell imedia 1958),is this the info you required?

If you put 4GB RAM in your PC the BIOS will recognise it all but your o/s will probably only recognise 3GB and that will be all it can utilise. :-(

I should have only ordered 1 stick then and not the 2 crucial recommended,Will using 1 2gb and 1 1gb be better for me ? thanks for the advice

That will be ok as long as your mobo doesn't need matched pairs?

If it's a 32 bit operating system and it has onboard graphics, the system will take the full 4Gb. Because the total ram is 4gb.

If the system has a seperate graphics card, then the system will not regester the full 4Gb. because the system is using more than 4Gb of memory.


if your computer utilises dual channel memory, you would be better off with two sticks of 512Mb of memory.
