This Dell RAM has 4GB DDR2 memory clocked at a speed of 400MHz.
It is made up of 2 sticks and has a voltage of 1.80V.
| 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 | 400MHz | 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 | |
| Voltage | 1.80V | Modern Intel systems require 1.5V or lower, AMD require 1.95V or lower. Can be changed in the BIOS | |
| Timings | CL 4 | 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 4GB, the 4GB (2X2GB) Nemix Ram Certified DDR2 ECC Memory for Dell PowerEdge 1800 1850 1855 A0751671 A1461052 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 Dell DDR2 RAM has a speed of 400MHz. RAM speed is not a crucial feature, but it does contribute significantly to PC games and certain applications like video-editing software. 400MHz is quite a poor speed, so would negatively impact the performance of both of these.
The CL RAM timing, or CAS latency, for this RAM is 4. This is the time it takes to send a column address and get a response. Generally speaking, the lower the latency the better, but there are other contributing factors such as clock speed.
