Unfortunately, no. DDR RAM will not work in a DDR2 motherboard, and DDR2 RAM will not work on a DDR3 motherboard.
There are a few motherboards that have slots for both DDR and DDR2, so it is conceivable that there could be motherboards with slots for both DDR2 and DDR3.
DDR3 uses 1.5V; DDR2 uses either 1.8V or 2.5V
DDR3 memory provides a reduction in power consumption of 30% compared to DDR2_SDRAMmodules due to DDR3's 1.5 V supply voltage, compared to DDR2's 1.8 V or DDR's 2.5 V.
sorry bout this, but the md2614u only supports ddr2 memory, and the limit on RAM is 4gb.
No, you can't use same DIMM slots for DDR2 and DDR3 due to different position of the key and interface incapability.
No, it only accepts ddr3.
Computer uses Memory installed on DIMM Slots on Motherboards.Nowadays different versions of DDR RAMs are used (DDR1, DDR2 & DDR3).Laptops use similar memories (DDR1, DDR2 & DDR3) but in small form of DIMM Sockets called Small Outline Dual Inline Memory Modules (SO-DIMM) memories.
DDR3 is better at the moment, however to make full use of DDR3 RAM you need a DDR3-compatible motherboard as well as a multi-core processor.
Todays Computers use DDR2 or DDR3. In rare cases, they may use DDR4. DDR means Double Data Rate. A application can run good on 512 MB on DDR2.
In computing, a computer bus operating with double data rate transfers data on both the rising and falling edges of the clock signal. This is also known as double pumped, dual-pumped, and double transition. DDR2 stores memory in memory cells that are activated with the use of a clock signal to synchronize their operation with an external data bus. Like DDR before it, DDR2 cells transfer data both on the rising and falling edge of the clock (a technique called "dual pumping"). The key difference between DDR and DDR2 is that in DDR2 the bus is clocked at twice the speed of the memory cells, so four words of data can be transferred per memory cell cycle. DDR3 memory comes with a promise of a power consumption reduction of 30% compared to current commercial DDR2 modules due to DDR3's 1.5 V supply voltage, compared to DDR2's 1.8 V or DDR's 2.5 V. This supply voltage works well with the 90 nm fabrication technology used for most DDR3 chips. Some manufacturers further propose to use "dual-gate" transistors to reduce leakage of current. The main benefit of DDR3 comes from the higher bandwidth made possible by DDR3's 8 bit deep prefetch buffer, whereas DDR2's is 4 bits, and DDR's is 2 bits deep.
Here's what I found out for you. The DDR3 has 240 pins just like the DDR2, however, they will not be compatible, you will not be able to put a DDR3 into a DDR2 slot. The knotch on the stick of RAM is in a different location so it will not fit. So a new motherboard made for DDR3 will have to be used. They are currently out on the MAC Lite computers but not sure if Microsoft has any on the market yet. The DDR3 will use 1.5V, which is lower than the DDR2 1.8V.
The type of RAM you use is dependant on what your motherboard and CPU can handle. You want to change from DDR to DDR2? Id' recommend getting a new computer.
