RAM is the short-term memory that holds data for the apps and files you have open. It is unlike the hard drive, which stores your long-term files and data.
If your computer runs out of RAM, it must move data from the faster hard disk to slower RAM and back again, slowing down your processing speed. Adding more RAM will solve this problem.
What is RAM?
Random access memory, or RAM, is the primary computer storage that processes information at lightning-fast speeds. It stores data immediately in use, and when the processor no longer needs quick access to it, the data is converted back to long-term storage on a hard disk or solid-state drive.
Computers today come with 4GB of RAM as a minimum. Those who need to multitask or play video games should consider upgrading to 8GB, and professional-level users may want 16+GB.
When you buy RAM, check the computer manufacturer’s website to make sure it supports the form factor of your motherboard. The slots for RAM are usually notched so you can’t insert a module in the wrong direction. Most modern computers have DIMM slots, but high-end systems may use RIMM slots. DIMM and RIMM modules look alike, so the manufacturer of the memory you buy should provide a list of which type of slots your computer supports. This will prevent you from buying a new module and finding out it’s not compatible with your system.
How much RAM do I need?
RAM is a crucial computer component that ensures quick and efficient performance by providing the short-term data storage that the CPU needs to quickly pick up where it left off. Without sufficient RAM, your computer would experience a lot of slowdowns and freeze-ups.
The amount of RAM you need depends on your goals and tasks. For most people who use their computers for browsing the web, checking email, word processing, and managing digital photo albums, 8GB is usually enough. For more demanding tasks like playing resource-intensive video games, however, 8GB can be a bit restrictive.
For those who use programs like Adobe Photoshop or Premiere Pro, you’ll want to aim for 16GB at minimum. Some professionals (like 3D animators or game developers) may need even more. It’s worth noting, however, that more RAM doesn’t always mean faster performance. There are other factors at play, including the processor and GPU.
How do I install RAM?
Once you’ve purchased the RAM that is compatible with your computer (check out your system manual if you are unsure), the actual installation is quick and painless. Shut down your computer, remove the power cable and hold the power button on the case for a few seconds to discharge any capacitors (it is also wise to use this time to blow out any dust from your motherboard’s memory slots). Open up the case and locate the memory slots. You will find two to four slots, each with a notched end that matches the notches on the RAM modules. Toggle the plastic retention clips on each side of the slot and insert your RAM stick, lining it up with the notch.
It is important to install your RAM in the correct channel slots, starting with A2. For instance, if you are installing two sticks of RAM, it is best to install them in channels A2 and B2. This helps distribute the load between both processors and improve performance.
What type of RAM do I need?
RAM comes in sticks, or memory modules that snap into the memory slots on your motherboard. They are typically labeled for your convenience, however the best way to determine compatibility is by searching for your CPU and Motherboards specific RAM requirements on the manufacturers website.
Generally speaking, you want to look for DDR4 RAM which is the current standard for PCs. DDR4 has faster speeds, larger capacities, and lower voltages compared to previous generation SDRAM. It is important to note that DDR4 modules are not backwards compatible with DDR3, as they have different pin counts, timings and voltages.
Capacity: Measured in gigabytes (GB) – a higher capacity will allow for more applications to run simultaneously. Speed: Determined by the RAM’s CAS / CL latency and clock rate. The lower the latency, the better.
