FAQ:

Q: Which is the best DDR2 RAM?

Q: What is the difference between DDR and DDR2 RAM?

A: DDR vs. DDR2. DDR RAM stands for Double Data Rate Random Access Memory. DDR2 is the second generation of DDR RAM. DDR and DDR2 are both types of SDRAM . 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.

Q: Can I use DDR3 RAM instead of DDR2?

A: This difference in notch position is also why you can’t use DDR3 RAM in a DDR2 system or install DDR2 RAM into a DDR3 slot (even though they have the same number of pins). In short, DDR2 and DDR3 RAM are not compatible with each other: If your motherboard has DDR2 RAM slots, then you can only use DDR2 RAM.

Q: How does DDR SDRAM work?

A: DDR SDRAM. Compared to single data rate ( SDR) SDRAM, the DDR SDRAM interface makes higher transfer rates possible by more strict control of the timing of the electrical data and clock signals. Implementations often have to use schemes such as phase-locked loops and self-calibration to reach the required timing accuracy.
