When you build a new desktop computer or need to upgrade the RAM/memory in your current desktop or laptop, one of the most important components is RAM (also known as memory or Random Access Memory). RAM is a form of intermediate storage where data from, for example, the operating system, programs and other data is temporarily stored so that the computer has fast access to the data the computer needs. When the computer's RAM is exhausted, data will be downloaded directly from your computer's hard drive or SSD, and this is where you will find that your computer has too little RAM or need extra RAM.
Within RAM, there are many different standards of RAM:
SD RAM - Synchronous Dynamic RAM is an older RAM standard that was introduced in 1993 and is used only on very old computers. The speeds are from 66 and up to 133 MHz and it has 168 pins connection.
DDR RAM - Double Data Rate RAM replaced SD RAM, and introduced a double bandwidth relative to SD RAM. The speeds are from 133 and up to 200 MHz (called DDR-266 and up to DDR-400). Available for desktop with 184 pins and for laptop with 200 pins.
DDR2 RAM - DDR2 RAM replaced the first generation DDR RAM, introducing a double bandwidth relative to DDR RAM. The speeds are from 200 and up to 400 MHz (called DDR2-400 and up to DDR2-800). Available for desktop with 240 pins and for laptop with 200 pins.
DDR3 RAM - DDR3 RAM continues the doubling of the former DDR generations and was introduced in 2007. DDR3 is available in two essentially different versions, DDR3 and DDR3L (L stands for low voltage and it uses less power than standard DDR3). Speeds were given a significant boost and it resulted in speeds from 1066 and up to up to 3000 MHz (called DDR3-8500 and up to DDR3-24000). DDR3 and DDR3L have the same number of pins. It is therefore only the motherboard or laptop specifications that determine which type of DDR3 is used in the motherboard or laptop. Available for desktop with 204 pins and for laptop with 240 pins.
DDR4 RAM - DDR4 RAM is the latest RAM technology that really hit the market in 2015 with the launch of the Intel Skylake platform. The speed was given another remarkable boost. The speed starts from 2133 MHz and there are models with over 4000 MHz. Available for desktop with 288 pins and for laptop with 260 pins.
Most newer motherboards often require, for instance, 2 RAM sticks (Dual Channel), 3 RAM sticks (Triple Channel) or 4 RAM sticks (Quad Channel). It is recommended to use the number of RAM sticks indicated by the motherboard manufacturer for the best performance. Additionally, you can buy sets packed with 2 or 4 RAM blocks, which are tested at the factory to be working together. Use the "Number of modules" filter to select packs of 1, 2, 3, 4, 6, or 8 RAM sticks.
In addition to the above standards, there are also special RAM for servers that are registered and with ECC (Error Correcting Code). If you are in doubt about which RAM sticks you need for your server, you can find the correct RAM with Kingston RAM configurator here - https://www.proshop.eu/RAM-Guide.htm.
For older computers, both laptop and desktop as well as Apple Mac, there may in many cases be special RAM that ensures the best compatibility. You can find help with the Kingston RAM Configurator here - https://www.proshop.eu/RAM-Guide.htm.
