RAM keeps information needed for tasks within reach of your computer’s processor. Without it, games would run at a crawl and apps wouldn’t open quickly.
Modern PCs need at least 8GB of RAM to operate, while hardcore gamers and video editors may require more. You’ll also want to consider memory speed and latency, which can boost performance.
How It Works
When you open an application, save a file or jump in a video game, the computer operating system moves that data to RAM. It’s much easier to work with if it’s in short-term memory instead of buried deep inside your hard drive, which is why RAM makes your computer run faster.
When a bit is needed, the CPU or memory controller reads the row lines of a RAM cell to determine which capacitors should be recharged with electrons (for a 1 or 0). Each time this happens, it takes 70 nanoseconds.
This process is repeated thousands of times per second. FPM and EDO DRAM wait for the entire process to complete before moving on to the next column or row, but SDRAM (synchronous dynamic random access memory) skips this step to increase speed. It’s usually sold in modules that contain multiple chips, so you can choose from different densities of pc ram. Each chip has a unique circuit board and connector that matches the existing ones on your computer for optimal performance.
Why You Need It
When you click a link to go to a website or open a new tab, a series of capacitors and transistors (basically switches) in your RAM are instantly filled and emptied with electricity to translate that data into the web page you see. This is why your computer can do things so quickly.
RAM acts like the digital countertop on which you place your most important files, allowing you to work with them faster and more easily than thumbing through a filing cabinet (your storage drive). It’s also much easier to switch between tasks when you have more workspace available.
If you find your computer sluggish and unresponsive, you may need more memory. A good rule of thumb is to get at least 16GB if you plan on using your PC for anything beyond light browsing and gaming. If you do video editing or more intensive games, consider going up to 64GB. The more you have, the better your system will perform.
How Much You Need
When it comes to RAM, your needs and what you want your PC to do will determine the amount you need. If you use your computer to write Word documents, surf the web, and play Solitaire, a laptop with 4GB of RAM will likely be enough for you.
However, if you’re a gamer, you may need more than 8GB of RAM for smooth gaming performance. You’ll also need enough RAM to handle multiple browser tabs and demanding apps like video editing suites.
16GB of RAM is often considered the sweet spot for PCs and laptops. It’s enough to run the latest games and gives you some headroom for other tasks. If you’re a serious gamer or you’re planning on using resource-intensive software like 3D modeling applications or 4K video and photo editing software, 32GB of fast RAM will give your system a boost.
What to Consider
When shopping for RAM, it’s important to consider the capacity based on your needs, as well as the speed. Higher speeds are better, but they can come with an added cost.
Another thing to keep in mind is the form factor and compatibility. You want to be sure that the RAM you choose fits in your motherboard. Also, you want to ensure that the timings and voltage are compatible with your system.
In terms of form factor, there are two main types: DIMM and SO-DIMM. DIMMs are the full-fledged sticks of RAM seen in desktop computers, while SO-DIMMs are typically used in smaller cases and PCs with small form factors. You should also look at the frequency and timings of the RAM you’re considering. Oftentimes, these can be adjusted with the right BIOS settings. Timings, which are also referred to as latencies, determine how long it takes for the RAM to retrieve data that the CPU requests.
