The most obvious factor on how to differ DDR3 from DDR2 memory is appearance. But, that is not as simple as it might seem. Unless you can find the specific reference on the memory stick, you will need to look at the key notch. Along the bottom of the memory stick, 240 pins insert into the motherboard. Among the pins is a notch. That notch prevents inserting the wrong type of memory into an incompatible slot. Looking from the top side, the notch on the DDR2 lies slightly to the right of the middle point of the memory stick. On the DDR3, the notch is slightly to the left of the middle.

DDR2 memory sticks do not fit into the slots for DDR3 sticks or vice versa. One reason why many manufacturers have been slow to adopt the newer DDR3 technology is because there is no backwards compatibility between the two. You cannot use a DDR3 when you do not have an appropriate slot in the motherboard for it. Some newer motherboards come with the ability for both types of memory to work. However, it is important to know how to differ DDR3 from DDR2 memory before you purchase it.

What else makes these memory sticks different? Transfer speed on DDR3 is double that of the DDR2. Transfer rates on DDR2 range from 400 to 800 Mbps. On the DDR3, the range is 800 to 1600 Mbps. The DDR2 has four internal banks of memory while the DDR3 has eight. The DDR2 does 4-bit prefetch and the DDR3 does 8-bit prefetch. The DDR2 uses more voltage than the DDR3 does. The DDR2 runs with 1.8V while DDR3 runs with 1.5V. DDR3 memory has a slightly higher latency than the DDR2. There are other technical differences between the two as well.

Currently, there is another significant way on how to differ DDR3 from DDR2 memory. The price is higher for the DDR3 memory sticks. Prices have continued to drop ever since the DDR3 came on the market a few years ago. However, the DDR2 sticks are still lower in price. But, newer motherboards are pushing the prices down on DDR3. The demand for the newer technology is starting to grow as higher memory requirements come into play with faster motherboards and chipsets. However, with the newer DDR4 technology planned for a 2012 release, the future of the DDR3 is still in question.

Your Motherboard supports only DDR2 800 / 667 MHz DIMMs, DDR2 and DDR3 are not physically compatible, the memory pins of DDR3 cannot fit into that of DDR2 slot. There are alternatives to solving you problem. You can buy dual combo DDR2 and DDR3 motherboard manufactured by MSI, particularly 790GX-8D and the P45-8D. NO DDR2 is for a DDR2 slot and DDR3 is for a DDR3 slot. Is it that you only have two DDR2 slots or something? They do sell 4GB sticks of DDR2 (so two of them would give you 8GB) but they are.

• Memory - Is a DDR3 MB compatible with DDR2 RAM?The Like the title implies, I am wondering if you can put ddr2 ram into the same slot that ddr ram goes i just ordered a ddr2 ram and i.DDR3L modules are backwards compatible with DDR3 by design.
• No, ddr2 and ddr3 are not compatible because there's a slot on the pins that are in different areas. You won't be able to fit ddr3 memory in a ddr2 mobo. For that specific mobo, the specs looks like it will only take ddr3, whether it would be ECC or non-ECC. You won't be able to fit your old ddr2 memory in there.
• This is not possible because the two memory boards are designed differently. A DDR3 memory won't fit at all in the slot for DDR2 memory. The same holds true if you want to add DDR2 memory to a DDR3 slot. However, they did build a few motherboards that you could either use DDR3 or DDR2 on the board.
