On-Die Termination With DDR, excess signal noise was eliminated by resistors built into the motherboard, but DDR2 has the terminating resistors built into each memory chip.

Package Another cost of the increased speed is the requirement that the chips are packaged in a more expensive and more difficult to assemble BGA package as compared to the TSSOP package of the previous memory generations such as DDR. Power Savings with DDR2 Power savings are achieved primarily due to an improved manufacturing process through die shrinkage, resulting in a drop in voltage requirements 1.

For the average user, it really won't make much of a difference. In most cases, other upgrades will improve your computer's performance more. The main scenario where the intricacies of RAM really matter is in heavy use, such as in servers.

These machines run heavy loads constantly, meaning that every bit of performance is vital. In normal use, you'd be hard-pressed to feel a difference between two systems with identical stats except for the generation of RAM.

If you buy a prebuilt computer off the shelf, everything is already assembled, so there's no worry. But if you're building your own PC, you should be aware of other RAM values aside from the generation that we've focused on here. Have a look at our general guide to RAM , which goes into more detail on other specifications.

Aside from making sure you purchase RAM that's compatible with your system ideally the newest generation , you don't need to worry much about it. But it's useful to know what all those numbers and letters mean for RAM. Save Article. Improve Article. Like Article. Last Updated : 24 Jul, This version of RAM was developed to achieve a high data rate for block-transferring. It is the successor to DDR where the main change is applied to the operational frequency between the RAM chip and the prefetch buffer, and the amount of both parameters is increased.

DDR has 4 internal banks.
