I was thinking of buying some memory for my computer.
At the moment i have 512mb ram.
I was thinking of buying another 512mb.
But when i open my computer up i cannot seem to find any infomation on the memory of what speed it is etc. i have had problems before installing new ram before becuz they were both different speeds so i just stuck with my 512ram.
My Comp is:
Processor:AMD Athlon XP 2400+ 2000MHz
Memory (RAM):512MB
Mainbroad: K7S8X

and my memory is Nanya 512mb
i do not know what the pc of the memory and i do not know how to find out.

Any suggestions what memory to buy or any help?


Thanks
