The two communicate in different ways, so they are incompatible software-wise. They are also physically incompatible due to a different pin arrangement, different notch locations, and different voltages.
The Slot layout.
Memory Ram
the different notch positions keep someone from installing a DDR DIMM or DDR2 DIMM in the wrong memory slot.
They are physically notched different, so that one cannot be firmly seated or inserted into the other.
A DDR2 memory stick cannot be installed correctly in a DDR slot.
I just put a PC2 6400 in the slot that had DDR2 533. The motherboard beeped when I turned the computer on. This beeping is an indication that the memory is not installed. Therefore in my case the answer is no.
This is impossible to do without physically breaking the DDR socket. If you did manage to do this you're going to need to buy a new motherboard and ram. You probably shouldn't be building your own computer.
You cannot use DDR2-5300 RAM instead of DDR2-4200 RAM in a system that specifically requires DDR2-4200. While both are DDR2 types, they operate at different speeds, with DDR2-5300 having a higher bandwidth. However, if the motherboard supports DDR2-5300, the faster RAM will downclock to match the lower speed of DDR2-4200. Always check your motherboard specifications for compatibility.
well ofciurse it will lol
ddr1 and ddr2
Dual-channel architecture requires a dual-channel-capable motherboard and two or more DDR, DDR2 SDRAM, or DDR3 SDRAM memory modules. The memory modules are installed into matching banks, which are usually color-coded on the motherboard.
Unfortunately not. DDR has a different amount of pins compared to a stick of DDR II. Also the slot position is slightly different. Hope this helps Be Safe Cadishead Computers
