The fastest way to find your RAM

Open Settings, go to System, then About. Look for "Installed RAM" — that number is what you have. On Windows 10 and 11, this takes about 10 seconds and shows you the exact amount in gigabytes.

If you are on an older version of Windows or prefer a different method, right-click "This PC" or "My Computer" on your desktop, select Properties, and you will see the RAM listed under System. Both routes show the same information; Settings is just faster on newer Windows versions.

If you want to know more than just the total — like the speed of your RAM or how many slots are filled — you will need to look deeper. The Settings screen tells you the amount; it does not tell you the type or configuration. The sections below cover those details.

Key Takeaways

  • Settings > System > About shows your total installed RAM in seconds on Windows 10 and 11.
  • Right-clicking "This PC" and selecting Properties works on all Windows versions and shows the same total.
  • Task Manager's Performance tab shows how much RAM you are currently using, not how much you have installed.
  • System Information (msinfo32) reveals RAM speed, type, and how many slots are occupied, which Settings does not show.
  • CPU-Z is a free third-party tool that displays detailed RAM specifications in a single window.

Using Task Manager to see RAM in use right now

Task Manager shows you how much of your RAM is being used at this moment, not how much you own. Press Ctrl+Shift+Esc to open it, click the Performance tab, then select Memory on the left. The top number shows total installed RAM; the graph below shows how much is in use.

This is useful if you want to know whether your computer is running out of memory while you work, but it will not tell you the specifications of your RAM itself. If you close Task Manager and open it again an hour later, the "in use" number will likely be different because different programs are running. The total installed RAM stays the same.

System Information for RAM speed and type

If you need to know whether your RAM is DDR4 or DDR5, or what speed it runs at, Settings will not show you that. Open System Information by pressing Windows key + R, typing msinfo32, and pressing Enter. Look for "Installed Physical Memory" to confirm your total, then scroll down to find entries labeled "Memory Speed" or similar details about your RAM modules.

System Information is built into Windows and does not require installation. The display can be dense and technical, but the information is reliable. If you see multiple entries for memory speed, that usually means you have multiple RAM sticks installed, and each one is listed separately.

CPU-Z for a clearer view of RAM details

CPU-Z is a free program that shows your RAM speed, type, and how many sticks you have in a single, straightforward-to-read window. read it from cpuid.com (the official site), install it, and open the Memory tab. You will see the total capacity, the type (DDR4, DDR5, etc.), the speed in MHz, and how many slots are in use.

CPU-Z is not made by Microsoft, but it is widely used and trusted by people who build or upgrade computers. It shows the same information as System Information, just in a format that is easier to scan. If you plan to buy more RAM or troubleshoot a memory problem, CPU-Z often makes the details clearer than Windows built-in tools.

What the numbers mean

RAM is measured in gigabytes (GB). A modern PC typically has 8 GB, 16 GB, or 32 GB. More RAM lets your computer run more programs at once without slowing down. If you have 8 GB and you open 20 browser tabs, Photoshop, and Spotify, your computer will start using your hard drive as temporary memory, which is much slower.

RAM speed is measured in MHz. DDR4 RAM usually runs at 2400 to 3600 MHz; DDR5 runs faster. For most people, the total amount matters more than the speed. If you are buying more RAM to add to what you have, matching the speed of your existing RAM is important — mixing speeds can cause problems.

The type (DDR4 vs. DDR5) matters because you cannot put DDR5 RAM into a slot designed for DDR4. If you ever need to upgrade, you will need to know which type your motherboard accepts. Your motherboard manual or the CPU-Z Memory tab will tell you.

Checking RAM on a laptop

The same Settings and System Information methods work on laptops. Press Windows key + Pause/Break, or go to Settings > System > About, and you will see your installed RAM. The difference is that most laptops make it harder or impossible to upgrade RAM yourself — some have RAM soldered directly to the motherboard, which means you cannot add more later.

If you are thinking about upgrading a laptop, check whether the RAM is removable before you buy new sticks. CPU-Z will show you how many slots are in use; if all slots are full and the RAM is soldered, you cannot upgrade. If you have one empty slot, you can add one more stick. A laptop manual or the manufacturer's support page will tell you whether your model allows upgrades.

Frequently Asked Questions

Why does Task Manager show less RAM in use than I have installed?

Because Task Manager shows only the RAM your programs are actively using right now. Windows keeps the rest available for new programs. If you close some programs, the "in use" number drops. The installed total never changes — that is the physical RAM in your computer.

Can I add more RAM to my computer?

On a desktop, usually yes. On a laptop, it depends on the model. Check your motherboard manual or laptop manual to see how many RAM slots you have and whether they are empty. If all slots are full, you would have to remove existing RAM to add more. Some newer laptops have RAM soldered to the board, which means no upgrades are possible.

What if Settings shows a different RAM amount than CPU-Z?

They should match. If they do not, restart your computer and check again. A mismatch usually means one program is reading cached information. If the difference persists, one of your RAM sticks may be failing or not fully seated in its slot — this is rare but worth investigating if you see consistent differences.

Does more RAM make my computer faster?

It makes your computer faster at running many programs at once, not at running a single program. If you have 8 GB and you only ever use a web browser, adding RAM will not speed up the browser. If you run Photoshop, Chrome with 30 tabs, and Spotify at the same time, more RAM prevents slowdowns from memory pressure.

Is DDR4 or DDR5 better?

DDR5 is newer and faster, but DDR4 is still common and fine for most tasks. Your motherboard determines which type you can use — you cannot choose. If you are building a new computer, DDR5 is becoming standard. If you have DDR4, there is no reason to replace it unless you are upgrading your motherboard anyway.
