Is DIM better than SDRAM for my Dell computer? It only has 32mg of SDRAM in it. It has 3 sockets. I can only afford 256mg of just one of these kinds of memory. Of course, I think adding 256mg of SDRAM into one socket would 288mg of memory wouldn't. From what I read, DIMM is a higher quality than SDRAM. Does the increased quality make it any faster?
