When you type a document, save a photo, or play a game on your computer, your RAM is working hard behind the scenes. It holds the information your PC needs to run applications and programs, making it much faster than non-volatile storage devices like SSDs or HDDs.
Adding more RAM improves performance. However, the process isn’t always as simple as inserting more sticks of RAM into your computer.
Memory Types
Memory is volatile, meaning it loses data when the computer shuts down. It stores data and instructions for processing by the CPU. Its fast access speed improves the performance of a computer system. Non-volatile memory retains data for a longer period after power is turned off. Examples include hard drives and permanent storage areas like ROM (Read Only Memory).
Depending on the type of memory, it may need to be refreshed periodically. Some memory types need to be refreshed more frequently than others, such as SRAM (Static Random Access Memory). The circuits in this type of memory use flip-flops to store data, reducing the amount of time needed to refresh it.
Unlike DRAM, SRAM uses only a single set of transistors for each memory cell. As a result, it has faster access times and requires less power to operate. It also has a larger capacity than DRAM, making it the memory of choice for high-performance applications.
Memory Capacity
For most users, the RAM that comes with their computers will be more than enough for everything from browsing the web to editing documents and photos. However, gamers and those who need to work with large files will benefit from upgrading their RAM to 16 GB or more.
Computer RAM works by holding data close to the processor, which makes it easier to access. It’s also faster than hard disk storage, which is why it’s important to have a good amount of memory available.
When your computing demands exceed the amount of memory you have, the operating system will shift a program from your RAM to your hard drive. This process, called paging or swapping, takes time and can cause delays. Adding more RAM to your computer can prevent this from happening by increasing the speed at which your machine operates.
Memory Speed
Like a large desk, RAM allows you to work on multiple projects at once without having to thumb through a filing cabinet (your hard drive). However, it takes time to access files, so the more memory you have the faster your PC will run.
Aside from the capacity, speed is another important consideration when purchasing RAM. Frequency is how fast data flows in and out of the memory, while latency is how long it takes for the CPU to send a command to the RAM and receive a response.
Higher RAM clocks can improve performance for certain tasks, such as encrypting files or performing (de)compression with a packing program. But for most applications, it’s lower latency that counts. Most users can get the best performance out of their RAM by using XMP, which sets the timings automatically. This is true for both Intel and AMD processors. The only exception is when the processor is operating at its limit, in which case a high clock rate can bring significant improvements.
Memory Problems
A bad computer’s RAM can cause the PC to crash, slow down to the point that it is unusable, or display random error messages. In addition, users may notice that websites load slowly, and local programs take minutes to open. This phenomenon usually indicates a memory problem and can result in data loss. Backing up important files frequently with EaseUS Todo Backup will help to protect your data from sudden data loss.
Unlike a hard drive or SSD, which can store data for long periods of time, RAM is volatile and loses its contents when the power to the PC is turned off. Therefore, it is a good idea to regularly clean the computer and its components to prevent dust from blocking connections.
In addition, the BIOS or system firmware might need to be updated to support a higher memory capacity or other changes. Lastly, using software to test individual modules can pinpoint the source of a problem.
