What does ddr3 stand for

Voltage is another important aspect of RAM generations. DDR3 was introduced in and while it's still used with some older systems today, DDR4 has become the standard. The maximum you'll see in the wild is usually 16GB. But DDR5 is on the horizon, expected to launch sometime in We've thrown around a lot of values above, but don't feel overwhelmed. The average user shouldn't ever have to worry about which generation of RAM to buy.

You might wonder how the different RAM generations affect performance. 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. Each bank group has the feature of singlehanded operation.

Figure 1. The pin count and key notch location for each DDR generation are different. The following table compares the different DDR generations. DDR Evolution. Table 1. Comparison of different DDR generations. Lower power. DDR4 modules are more energy-efficient, operating only at 1. The reduced power consumption gives substantial power savings and allows operation at higher speeds without higher power and cooling requirements.

Higher module density.
