|Total Memory||4GB||The amount of memory is the RAM's primary feature and defines how much data it can store for temporary fast access|
|Total Speed||2133MHz||Speed defines how many data transfers can be made per second.|
|Stick Count||1||The number of sticks define the number of slots in the motherboard necessary to house the RAM|
|RAM Type||DDR4||The RAM type defines compatibility with motherboards, as well as the limits to performance|
|Voltage||1.20V||Modern Intel systems require 1.5V or lower, AMD require 1.95V or lower. Can be changed in the BIOS|
|Timings||16-18-18-36||Timings show latency, row address to column address delay, row precharge time, and row active time|
Rather than storing data permanently like in large capacity hard drives, RAM provides a temporary cache that your system uses to store the data that you are currently using. This makes accessing the most relevant data much faster, because accessing RAM requires much less time than your hard drive. In fact, most systems are configured to use the hard drive as a substitute for RAM when the RAM is being overloaded with data. This can bring your PC to a crawl, however, and is why having enough RAM is crucial.
DDR4 RAM is the latest technology and has the highest performance limits of any market RAM. Not yet available to consumers, it offers various improvements over DDR3 including both power efficiency and performance. While its improvements may be less marked than those of earlier iterations, new motherboards are going to begin implementing DDR4 as standard, which should be kept in mind when purchasing new RAM.
With a total memory of 4GB, the Crucial 4GB Single DDR4 2133 MT/s (PC4-17000) CL15 SR x8 Unbuffered DIMM 288-Pin Desktop Memory CT4G4DFS8213 has the capacity to help run multiple general applications simultaneously. It should be just enough for gaming and general PC usage requirements, but considering how cheap RAM is, an upgrade may be a safer long-term option that will provide performance benefits in almost all areas of general PC use. RAM upgrades have, after all, been traditionally recommended as one of the cheapest, quickest, and easiest ways to improve the performance of a sluggish system. This Crucial DDR4 RAM has a speed of 2133MHz. RAM speed is not a crucial feature, but it does contribute significantly to PC games and certain applications like video-editing software. 2133MHz is among the fastest speeds available on the market, so this RAM will exhibit superb performance helping to run either of these.
The RAM timings reflect different performance benchmarks. The first number, the CL, or CAS (Column Address Strobe) latency, is the time it takes to send a column address and get a response. This Crucial DDR4 RAM has a CL of 16. Generally speaking, the lower the latency the better, but there are other contributing factors such as clock speed.
The second number, the tRCD, or Row Address to Column Address Delay, is the required clock cycles necessary after a row of memory is opened before columns within it can be accessed. The tRCD of this Crucial DDR4 RAM is 18.
The third number, the tRP, or Row Precharge Time, is the clock cycles necessary after the precharge command is executed before the next row can be opened. The tRP of this RAM is 18.
The last number, the tRAS, or Row Active Time, is the clock cycles necessary after a bank active command before the ensuing precharge command is executed. The tRAS of this RAM is 36.
