When you open a file or website, or jump into a video game, your computer is processing a lot of information. That data is stored either in long-term storage (hard drives or SSDs), in cache, or immediately in RAM.
RAM is like the top of your desk – all the stuff you need to work on is within reach. It’s also incredibly fast.
What is RAM?
RAM is short-term memory that helps your computer do things like open apps and work with files. The more RAM your computer has, the faster it works.
RAM uses a circuit board with capacitors and transistors to store data. When you click a link to go to a new website, the computer moves the information from the website’s page into RAM so it can easily find it again.
This kind of quick access is what makes RAM so important. Non-volatile storage like your hard drive or SSD can save information for years, but it’s millions of times slower to access than RAM.
The fast speeds of RAM also make it easier for your CPU to work with complex information. It can even process data at the same time that it’s being stored, so it doesn’t have to wait for its turn. The faster your CPU can work, the better your overall experience will be. This is why it’s important to keep junkware and unneeded background processes out of your RAM.
How much RAM do I need?
The amount of RAM your computer needs depends on what you use it for. For general use, including web browsing, responding to emails, and light multitasking, 4GB to 8GB should be adequate.
If you want to play games, you’ll need a bit more than that. 8GB may be enough for some older, low-resolution titles, but newer games need at least 16GB to run smoothly.
Video editing, motion graphics software, and virtualization also require a lot of RAM. Professionals need between 16GB and 32GB for smooth workflows.
What is the difference between SRAM and DRAM?
Essentially, SRAM is faster and more expensive than DRAM. It stores bits as voltages whereas DRAM uses transistors and capacitors to store the state of each bit. SRAM also does not need refreshing so it consumes less power than DRAM.
DRAM, on the other hand, is cheaper but needs to be refreshed every so often. The more it is refreshed the quicker your data can be accessed. It’s why you can open a software program again almost instantly after closing it.
Generally speaking, DRAM is what you will find in your main memory whereas SRAM is used for cache. You may even see VRAM on your computer which is RAM dedicated to video. VRAM can be a little slower than DRAM but it’s much cheaper and denser. It also syncs with the system clock which makes it more efficient.
How do I install RAM?
RAM is your computer’s short-term memory, storing the information that your processor needs to run applications and open files. Upgrading your PC’s RAM can improve performance, allowing for faster multitasking and smoother application use.
To install RAM, first make sure that the form factor of the new RAM is compatible with your motherboard by using a tool such as Google or entering your system specs into a website to check. You can also look in your BIOS to see what type of RAM is currently installed, or by hitting Windows + R and typing msinfo32.
Next, remove the old RAM by jiggling the plastic retention clips on either end of the module until it pops up and out (note its orientation for when you are installing the new RAM). Place the RAM into a static bag to prevent damage. Finally, lock the clip back into place by gently pressing down on it. Repeat this process for the other stick of RAM.
