No! They will not even fit into the socket unless its the correct one.
No, the slots for DDR2 RAM is different from the DDR RAM. You cannot use DDR RAM with DDR2 slot.
No DDR and DDR2 Slots are differant on Motherboard so cant replace each another
no...you can't
DDR is not as fast ad the DDR2 ans that is the main difference.
ddr, or ddr2
No DDR2 and DDR are not compatible and so you can not add DDR2 RAM module in a DDR Slot. Electrical specifications like voltage, signal pinout and even mechanical size and shape of modules are different.
DDR by a long shot
No. DDR RAM cannot be used to replace or upgrade a PC133 module.
DDR has a 184-pin DIMM interface and DDR2 has 240. DDR2 runs cooler and has generally slower timings but is a lot faster than DDR in the end. DDR2 is capable of holding more ram on one DIMM.
DDR2 RAM is SDRAM. It provides double the bandwidth of DDR RAM, but at a higher latency. DDR3 is much better than DDR2 performance-wise, and it uses less voltage.
