The true latency is a good indicator of memory performance. It is calculated from the CAS latency (CL) and transfer rate.

The speed of the memory, as given by the manufacturer. Also known as the Tested Speed. Note: it requires a CPU/motherboard that can support the speed, and may also require enabling XMP profiles.

The SPD (serial presence detect) speed of the memory. This is the speed that the memory runs at by default, without changing any BIOS settings or overclocking etc.

DDR (Double Data Rate) memory is the most common type of RAM. Newer versions of DDR memory support higher maximum speeds and are more energy-efficient.

The CAS Latency (CL) timing of the memory.

The tRAS (Row Active Time) timing of the memory.

The tRCD (Row Column Delay) timing of the memory.

The tRP (Row Precharge Time) timing of the memory.

You should always make sure to buy the correct memory for your system. Common form factors include 288-pin DIMM for PCs and 260-pin SO-DIMM for laptops.

The total size of the memory, taking into account the size of a single module and the number of modules in the kit.

Samsung B-Die is a specific type of die (chip) used in some memory products. Many people favour this type of memory as it can run at speeds of 3200MHz or higher while also keeping CAS latency low (CL 14). These performance benefits are most notable when paired with an AMD Ryzen CPU.

The voltage of the memory.

The height represents the vertical dimension of the product.

The size of a single memory module.

Intel XMP (Intel Extreme Memory Profile) and AMD EXPO (AMD Extended Profiles for Overclocking) are features that allow you to easily overclock memory, simply by enabling the option in the BIOS.

Error-correcting code memory can detect and correct data corruption. It is used when is it essential to avoid corruption, such as scientific computing or when running a server.

Heat can have an impact on performance and reduce potential read/write speeds. An integrated heatsink (or heat spreader) helps to keep the component cool and operating at maximum efficiency.

RGB lighting allows you to choose between millions of colors and customize the look of your PC components.
