Okay, I currently have a Intel Pentium 4 2.8 MHz processor, Dell Dimension 4600 Motherboard, and (2x128)MB (PC2700) DDR SDRAM. My question is, can these sticks fit into my computer? They're "CORSAIR ValueSelect 1GB (2 x 512MB) 184-Pin DDR SDRAM Unbuffered DDR 400 (PC 3200) Dual Channel Kit System Memory"
