RAM is a type of computer memory that helps your computer run more quickly and smoothly. If you've ever wondered what type of memory does my computer has, this article can help.


RAM stands for random access memory, which means that any byte can be accessed directly without having to read from other locations in memory. In contrast, a disk drive uses sequential access, where data must be read sequentially from the disk surface to retrieve one byte of information.


A computer's memory is made up of several parts: primary storage, secondary storage, and cache memory. Primary storage or RAM is a form of semiconductor that can retain its contents as long as power is running through it. In other words, as long as your computer has power, the contents in its memory will not disappear. To understand how primary memory works, think about primary memory as being similar to an index card box at school - you can pick up a specific card from any time you need it and use it until someone decides to put it back in its box at the end of the day/class. Then, you can pick it up again at any time where you left off.


Secondary storage is also very important because it holds data for extended periods even when the power has been turned off. This type of memory is used to store files on your computer that are not immediately needed but will be required later. Secondary memory is made up of devices such as hard drives, tape drives, and optical drives (CD ROMs, DVD ROMS, etc.). While the contents in RAM might disappear if there's a blackout or other power disruption, these contents are written to or read from secondary storage by your computer first before they are lost.

Why You Need to Know How Much RAM Your Computer Has

The most frequent reason to check your system's RAM is to ensure that a game or program runs well. Before purchasing anything for your system that it may not support, make sure you know what you're getting into. This will help prevent you from being disappointed and irritated.


Another reason to know what type of memory does my computer has is to determine if you need more memory, or if your current amount of RAM is sufficient. If you find that your system runs slowly after extended periods of use, it might be time to consider upgrading your existing memory instead of purchasing a new system with more features. The best way to test this is by monitoring the activity light on your cable modem or router. If there's heavy traffic (i.e., large amounts of data being transferred) between your ISP and your PC, then adding extra RAM can help improve performance significantly. On the other hand, if you're not transferring lots of data but still require faster speeds, then it's time to upgrade that old Internet 2 connection to broadband.

DDR3 vs. DDR4

DDR3 and DDR4 RAM are two different types of double-data-rate SDRAM, the acronym for synchronous dynamic random-access memory. One of the primary distinctions between them is that DDR4 RAM has a higher clock speed (2133MHz versus 1600MHz). This means that DDR4 RAM can transfer data at a faster rate. But, because the two types of memory are not compatible, you may need to upgrade your computer's motherboard or other components to use DDR4 RAM.

How does my computer type affect the speed and strength of my RAM?

Types of RAM: DDR3 and DDR4

Computers come with different types of memories: SRAM, DRAM, and VRAM. The type used in most computers is known as DRAM (dynamic random access memory), which must be powered by a continuous flow of electricity to keep its contents available for the computer to use. As such, if there is an interruption in the power supply, all data stored within it will disappear quickly.

RAM might be referred to in several ways: UDIMM, RIMM, SODIMM, etc. Here's a quick guide to help you understand the differences between them:

-UDIMM is an abbreviation for Unbuffered DIMM. These types of RAM are used by desktops and motherboards that do not support ECC Ram (error-correcting code). This type of memory also has a lower price tag than its counterparts.

-DIMMs on the other hand may come with or without error detection capabilities which allow your computer to check if there was an error when saving data into it. If this is the case then the DIMMs are known as ECC Ram. Some computers require this type of RAM to run efficiently. One way to tell the difference between the two is that ECC Ram has a thin metallic strip at one end.

-RIMMs are known as Registered DIMM and have been around before DDR, which was first used back in 1994. RIMMs can help lower power consumption but they tend to be more expensive than their counterparts.

-SODIMMs are also known as Small Outline Dual In-Line Memory Modules. Like RIMMs, SODIMMs were introduced before DDR technology and maintain most of their original design. They've commonly been used for laptops memory modules because they tend to use less power than other types of memories.

Task Manager

The Task Manager is perhaps the most basic RAM test you may conduct on your PC. Simply press CTRL, ALT, and Delete simultaneously to launch the Task Manager on Windows 10 and earlier versions of the OS; then select the Performance tab. This will allow you to see the amount of RAM being used and to monitor its usage in real-time.

Memory Bottlenecking

Memory bottlenecks occur when the capacity of a computer's random access memory (RAM) is unable to cope with the number and type of programs running. This can result in slower system response times, lockups, crashes, and data loss and corruption. If your PC has a memory that is insufficient for the programs or processes that are running at any given moment, then it may take up all available system resources resulting in other tasks not working properly.
