This Corsair RAM has 2GB DDR2 memory clocked at a speed of 533MHz.
It is made up of 2 sticks.
Its timings are 4-4-4-12.
| Total Memory | 2GB | The amount of memory is the RAM's primary feature and defines how much data it can store for temporary fast access | |
|---|---|---|---|
| Total Speed | 533MHz | Speed defines how many data transfers can be made per second. | |
| Stick Count | 2 | The number of sticks define the number of slots in the motherboard necessary to house the RAM | |
| RAM Type | DDR2 | The RAM type defines compatibility with motherboards, as well as the limits to performance | |
| Timings | 4-4-4-12 | 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.
DDR2 RAM is now an old technology, with limits far below that of DDR4 and DDR3. Due to the prevalence of DDR3, DDR2 RAM is actually not particularly cheap or good value, and any new RAM is recommended to be DDR4 or DDR3 over DDR2.
With a total memory of 2GB, the Corsair 2GB (2x1GB) DDR2 533 MHz (PC2 4200) Desktop Memory (VS2GBKIT533D2) has the capacity to run very little at once, and may even struggle with a Windows installation. Avoidance of this RAM in any PC build is highly recommended. This Corsair DDR2 RAM has a speed of 533MHz. RAM speed is not a crucial feature, but it does contribute significantly to PC games and certain applications like video-editing software. 533MHz is quite a poor speed, so would negatively impact the performance of both 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 Corsair DDR2 RAM has a CL of 4. 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 Corsair DDR2 RAM is 4.
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 4.
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 12.
