Unlike the long-term storage of a hard drive, the data stored in RAM gets wiped when your computer shuts down. That’s why it’s essential to keep enough RAM around for the applications you use most often.
RAM is sold in sticks that snap into memory slots on your motherboard. The type of RAM you need depends on the kind of processor in your computer and its system requirements.
What is RAM?
RAM is your computer’s short term memory. It provides lightning-fast data access for apps, programs, and processes. It works in tandem with the central processing unit (CPU) to keep everything running smoothly.
When you play a video game or stream a movie, the data that supports those activities is stored in your computer’s RAM so the CPU can quickly access it. When you’re done, the operating system takes the data from RAM and puts it into longer-term storage on the hard disk or other long-term storage device.
RAM comes in sticks, or memory modules, that snap into the slots on the motherboard of your computer. They come in a variety of form factors and speeds, but the kind that fits your computer is determined by the type and model of your motherboard. It’s also important to choose RAM that’s compatible with your processor. This ensures it can operate at its maximum speed. Memory that is not compatible can cause your computer to run erratically.
How much RAM do I need?
The amount of RAM you need depends on how you use your computer. The most common use case is a laptop or desktop PC used for browsing the internet, word processing, sending emails, and light gaming. As little as 4 GB of RAM is enough for this but more is recommended.
The industry standard these days is 8 GB of RAM, which is enough to handle most day-to-day activities and play high-end games. More than 8 GB of RAM is typically reserved for computer enthusiasts and professional users who need to use programs like photo or video editing, 3D rendering, or host virtual machines.
Anyone who wants to run modern triple-A video games will need at least 16 GB of RAM. This is the sweet spot for computer performance. It is enough to allow you to play the latest games without any delay and also allows for software design and memory-intensive projects. You can always add more if needed but there will be a point at which it is overkill.
What is the difference between RAM and a hard drive?
RAM is like the top of your desk, storing all the things you use frequently at arm’s length so you don’t have to spend time searching through drawers (like that Microsoft Word document you forgot to save before shutting down). It provides lightning-fast data access.
RAM can take the form of chips that are soldered directly to your motherboard or in memory modules that plug into sockets on your computer’s logic board. It’s volatile memory that maintains data only when your system is active, unlike a hard drive or solid-state drive that keeps data indefinitely until deleted.
Static RAM, or SRAM, does not require a constant flow of power to keep its memory cells filled (hence the name), but it is more expensive and less space-efficient than dynamic RAM, or DRAM. Modern computers typically use DRAM, which refreshes itself periodically but requires more overall power. The more RAM your computer has, the faster it will run.
How do I install RAM?
Adding RAM to your computer is one of the easiest upgrades you can do yourself. It’s also a great way to improve your performance, especially in games. Before you start, be sure that the RAM you purchase is compatible with your motherboard — this can be done by checking the manufacturer’s website or your PC’s manual.
Also, make sure that you’re installing the right kind of RAM. Desktop computers use DIMM (Dual In-Line Memory Module) slots, while laptops utilize SO-DIMM slots. Additionally, some motherboards require that you install RAM in pairs that are the same size and timings — be sure to check your motherboard manual for guidance.
Once you’ve confirmed that your RAM is compatible, turn off and unplug your computer before opening the case. You’ll need to open the case to access the motherboard, which can be difficult in a laptop. After you’ve opened the case, carefully remove the old RAM and place the new RAM in its slot. Ensure that the notch on the bottom of the RAM stick lines up with the bump in the motherboard’s slot to ensure proper installation.
