PC3-17000 DDR3 2133 Computer RAM

Random access memory, or RAM, is best thought of as the short-term memory of the computer. Sufficient RAM allows you to multitask and run many simultaneous programs or to run programs that require higher digital and data requirements. Luckily RAM is one of the easiest components to install or upgrade in a computer, making it a quick way to bring new life to old desktops.

What is memory frequency?

The frequency, or clock speed, of a DDR3 module is the four-digit number after the DDR generation. In this case, the clock speed is 2,133 MHz, which means that the memory operates at 2,133 cycles per second. This impacts how quickly a given stick of RAM can read and write, as well as response times. Some memories can be overclocked by a processor, which allows for high function without overheating.

What is memory timing?

Some forms of higher-end DIMMs will list their timing in addition to frequency. This is broken down into four numbers. For example, G.Skill offers the high-end Ripjaws gaming DIMMs that list their timing as 9-11-10-28. The first number is called CAS latency, which is how many cycles it takes for the DIMMs to start responding to a request for data. The second and third numbers address how long it takes for a given DIMM to find the data that is being requested. The last number, which is almost always the longest, is the row active cycle, or how many cycles a piece of information has to stay open for in order to be read properly. The lower these times are, the faster the computer can access information.

What does PC-17000 mean?

PC-17000 denotes how quickly a given DIMM can read or write to itself. This is directly tied to the clock speed of the module but is recorded as Mbs rather than hertz. This means a PC3 PC-17000 DDR3 2133 Computer RAM module can read or write at up to 17,000 megabytes per second. This doesnt count overclocking.

What kinds of computers are DDR3 DIMMs compatible with?

The DDR3 RAM is compatible with motherboards from many previous generation processor architectures from both AMD and Intel. Laptops, however, use a different kind of standard called SO-DIMM, as opposed to the standard DIMMs of desktops. If your computers motherboard uses DDR3 though, it will work with any clock speed of DDR3 module. Unfortunately, DIMM slots are all physically different across generations, meaning that DDR2 or DDR4 RAM will not fit in your desktop.
