If you don't know the exact model of your computer, the System Scanner tool can scan your computer hardware to automatically detect your system configuration and give you a report on which upgrade is right for you. The Crucial® Advisor™ tool will list only compatible memory for your system. The right type of memory to use is the one that your computer is compatible with! The easiest way to find the right memory for your computer is to look up your system with the Crucial® Advisor™ tool.

They will not function and will not even fit in the same sockets. You cannot mix and match SDRAM, DDR, DDR2, DDR3, DDR4, or DDR5 memory on the same motherboard in any system. This means that they can easily reach higher speeds, offering you a more efficient and smoother computing experience. Unlike DDR3 RAMs, DDR4 RAMs are designed to offer improved transfer rates and reduced power consumption. Generally speaking, motherboards are built to support only one type of memory. And when it comes to choosing the best RAM for your gaming rig, the perfect choice is a DDR4 RAM module. They are also different in height and thickness the increased height of DDR4 modules (31.25mm instead of DDR3's 30.35mm) makes signal routing easier, and the increased thickness (1.2mm vs. Frequently, DDR2-based systems can use memory installed in pairs to run in ' dual channel mode' to increase memory throughput even further.ĭDR3, DDR4 and DDR5 represent further improvements in memory technology, with improvements in bandwidth as well as power consumption, leading to better performance and stability as time went on and the standards evolved. Both DDR3 and DDR4 DIMMs are 5 inch (133.35 mm) in length but the pins in DDR4 are spaced closer (0.85mm) than DDR3 (1mm). DDR2 achieves speeds beyond that of DDR, delivering bandwidth of up to 8.5 GB per second. Systems implementing the follow up technology to DDR, called DDR2, began to appear in mid-2004. The most significant difference between DDR and SDR is that DDR reads data on both the rising and falling edges of the clock signal, enabling a DDR memory module to transfer data twice as fast as an SDR memory module.

Single data rate (SDR) SDRAM is the older type of memory, commonly used in computers prior to 2002.ĭouble data rate (DDR) SDRAM hit the mainstream computer market around 2002 and is a straightforward evolution from SDR SDRAM. Most desktops and notebooks use one of several popular types of dynamic random access memory (DRAM) for the main system memory.
