RAM (Random Access Memory) is an important part of any computer, but many people are confused about exactly what it does and why it’s necessary. In this guide, we’ll tell you all about RAM—what it does, why it matters, and how you can maximize the memory in your computer so that your system runs as smoothly as possible. We’ll also cover other types of computer memory such as ROM, hard drives, and virtual memory.
The basics of computer memory
There are two main types of memory found in computers: random access memory (RAM) and read-only memory (ROM). RAM is referred to as being volatile, meaning that if power were to be lost, anything stored there would be erased. ROM, on the other hand, doesn’t require power to maintain its contents. Generally speaking, a personal computer relies heavily on fast access to data stored in its system memory. As a result, any issues with said memory can have serious effects on performance.
All about SDRAM
Serial-attached memory (SDRAM) is a type of random access memory (RAM) that provides high-speed access to stored information. It uses parallel processing, where a single byte can be accessed simultaneously from multiple channels, unlike other types of memory where each channel can only read or write to its own address. SDRAM dramatically increases bandwidth compared to previous types of dynamic RAM. SDRAM’s transfer speed per clock cycle allows devices connected over a bus system to operate at peak data rates. For example, while many earlier DRAM chips could read or write data on average once every 12 ns, as of 2007 typical SDRAM operated with an average latency time of around 2 ns.
Which kind of RAM should you buy for the best performance?
For most desktop users, one of four kinds of memory will suffice: DDR3 (double data rate type three), DDR4, LPDDR3 or LPDDR4. You can also get SDRAM (single data rate) or RDRAM (Rambus DRAM). Deciphering all these acronyms might seem intimidating, but you don’t need to know how a car engine works to drive one—you just need to find one that meets your budget and performance needs.
How do you upgrade to more RAM in Windows 10, 8.1, 8, 7, Vista, or XP?
Fortunately, upgrading to more RAM on Windows computers couldn’t be easier. Here’s how you do it in just a few easy steps.
Is there a difference between PC3200 DDR 400MHz vs PC3200 DDR 333MHz RAM performance?
One of them is fast, one of them isn’t. Why does that matter when choosing a new PC3200 DDR 400MHz vs PC3200 DDR 333MHz Ram upgrade or purchase? That’s easy to explain; how much work can be done in a second to provide you with a better overall user experience.
Is ECC DDR2 Memory Cheaper than Standard DDR2 Memory?
We’re going to assume you’re familiar with how memory works; if not, a quick Google search can give you all of that information. Suffice to say, however, we all know how awesome having more memory can be for our computers: It enables faster processing, reduces crashes and allows us to run more programs simultaneously. So what is ECC DDR2 Memory? ECC stands for Error Checking & Correction. Let’s take a look at what this type of memory actually does.
How much RAM do I need in my new PC build / Mac build / gaming machine / notebook / ultrabook?
The memory (RAM) in your new PC, laptop or notebook will have a big impact on its performance. That’s because RAM serves as temporary storage space while you run applications on your device. If you choose too little RAM, applications will load slowly or fail to start altogether. But if you choose too much memory, that’s money down the drain. You may not know exactly how much memory (or how much of which type) you need in any given situation, but we can help.
Is 1GB or 2GB SDRAM better? Is 2GB really twice as good as 1GB when using dual channel technology?
This question depends entirely on what you are doing with your computer. The actual definition of 1GB and 2GB, as stated by Wikipedia, SDRAM or Synchronous DRAM is a type of dynamic random-access memory (DRAM) that synchronizes its internal clock to the system clock.
Why are there so many different types of memory modules (DIMMs)?
Dynamic random-access memory (DRAM) is a type of semiconductor device used to store and retrieve digital information. There are several types of DRAM, with various tradeoffs between cost, power consumption, security, performance, capacity and other factors. The different types of DRAM have come out over time: EDO DRAM, DDR DRAM and SDRAM, to name a few. Some modules also have dual ports so they can be accessed from multiple processors at once.
