Your computer uses RAM to store data for immediate access. It processes this data faster than the same information stored on a hard disk.
Your computer needs to have enough memory for the tasks it’s handling right now. More than that, and performance suffers. When that happens, the hard drive picks up the slack, slowing your computer down.
What is RAM?
RAM is the short-term storage your computer has for data it will need within the next few moments. It’s not the permanent storage like the folders where your files sit (which is a type of non-volatile system memory).
Your computer wouldn’t be able to operate without RAM because it would have to rely on its hard drive for all of its information. This would slow down the computer to a crawl while it searched through countless files for what it needed.
There are two main types of RAM, SRAM and DRAM. SRAM has capacitors that hold their power, so they don’t need to be refreshed (although they do use a small amount of energy constantly). DRAM uses transistors and capacitors that slowly discharge their electricity and needs to be refreshed frequently. These are typically found in a module that looks similar to a regular memory chip. Today, most computers use SDRAM. Older systems may still use legacy DRAM.
How much RAM do I need?
RAM provides high-speed, short-term memory for the CPU. Accessing data from RAM is orders of magnitude faster than accessing the hard disk drives or SSDs on a storage device, and that speed boost makes a real difference to performance.
Choosing the right amount of RAM depends on your computing needs. 8GB is a good starting point for casual users who want enough room for a few web browsing tabs open and light word processing or spreadsheet work. If you’re a keen gamer or want to be able to use demanding applications like video editing software, then 16GB is the minimum we recommend.
It’s also worth looking at RAM frequency – the higher the clock speed, the faster your CPU can retrieve data from RAM. This can make a big difference when running resource-hungry apps, especially games. You can check your current RAM speed in Settings > System > About this computer. There are also a number of tools available to help you find the best RAM for your computer.
What is the difference between RAM and VRAM?
RAM is random access memory that is plugged into your motherboard for the CPU to use. VRAM is on your GPU card and it does graphics processing tasks. VRAM is usually faster because it has dual-port technology, meaning data can be written to and read from at the same time.
While it may seem confusing, it is important to understand the difference between RAM and VRAM so you can make informed decisions about your computer hardware. If you want the best performance, it is crucial to balance your RAM and VRAM choices based on your specific needs.
RAM helps the CPU run smoothly by providing quick and direct access to data. It is volatile, however, and the data disappears when your PC shuts down. That is why it is important to back up your data frequently. RAM is available in densities ranging from multiples of 2 gigabytes up to 32GB. This makes upgrading RAM relatively easy.
How can I upgrade my RAM?
Whether you’re a casual gamer, a video editor or professional looking to boost productivity, upgrading RAM can make your PC more responsive and powerful. But it’s important to select compatible RAM modules in terms of type, capacity and speed.
To determine if your computer needs more memory, open Task Manager and check the Memory tab. This will display real-time usage of your computer’s available RAM, allowing you to gauge if an upgrade is worth the investment.
If you are planning on installing new RAM, shut down your laptop or PC and unplug all cords. Then, place it on a flat surface and locate the RAM access panel or case. You may need a screwdriver to open the casing and release any retention clips or levers. Once you’ve accessed the slots, carefully lift out the existing modules by releasing the clips on each end. Ensure that the notches on your new RAM sticks line up with those in your motherboard’s slots before gently snapping them into place.
