💡 Core Solutions in This Article:
▶ Check Speed via Task Manager (Fastest Method)
▶ Check Speed via Command Prompt (Most Detailed)
Understanding your hardware is the first step toward a smoother experience, whether for gaming or productivity.
Now, software demands have increased. Windows 11 updates, modern browsers, and high-fidelity games require faster data access. RAM (Random Access Memory) speed, measured in MHz (or MT/s), dictates how fast your processor can access temporary data.
If you are wondering how to check RAM on Windows 10 or Windows 11, it is usually because you want to:
Verify an Upgrade: Did the new sticks you bought actually run at the advertised 6000 MHz (DDR5)?
Troubleshoot Lag: Is your RAM running at a default "safe" speed (like 2133 MHz) instead of its XMP profile?
Match Components: You need to know your current speed before buying a matching stick to avoid compatibility issues.
Knowing how to check RAM speed ensures users won't leave free performance on the table.
Here are the native methods to check your memory specs without installing extra software.
This is the quickest way to answer "how do I check how much RAM I have" and how fast it is running. The following are screenshots of the steps I personally tried to solve this problem:
Right-click the Start button and select Task Manager, or simply press Ctrl + Shift + Esc on your keyboard.
Click on the Performance tab (the icon looks like a heart monitor graph).
Step 3. Select Memory
Click on Memory in the left sidebar.
Step 4. View Details
Look at the bottom right of the window. You will see:
Note: If the speed looks lower than what you paid for (e.g., 2133 MHz instead of 3600 MHz), you may need to enable XMP/DOCP in your BIOS.
If you want to know how to check RAM speed in Windows 11 with granular detail (like the manufacturer and speed of each stick), the Command Prompt is superior.
Step 1. Press Win + R, type cmd, and press Enter.
Step 2. Type the following command and hit Enter: wmic memorychip get devicelocator, manufacturer, speed
Step 3. The system will list every stick of RAM installed. If you see different speeds listed, your system will default to the speed of the slowest stick.
This method is great for a broad overview when you search "check ram speed".
Step 1. Press Win + S and type System Information. Click to open it.
Step 2. Scroll down the System Summary list.
Step 3. Look for Installed Physical Memory (RAM) to see the total amount (e.g., 32.0 GB).
Before you spend money on new RAM, it is crucial to understand if memory is actually your bottleneck.
Many users perform a RAM speed test because their computer takes forever to boot or load apps. However, the performance gap between a slow mechanical hard drive (HDD) or an older SATA SSD and a modern NVMe SSD is often more noticeable than the difference between 3200 MHz and 3600 MHz RAM.
Here is a comparison to help you decide what to check:

Conclusion: If your check ram speed results show you have decent speed (2666 MHz+) and capacity (16GB+), but your PC is still slow, the problem is likely your hard drive, not your RAM. You need to test and optimize your storage.
If your RAM is fine, use this professional tool to optimize your storage or upgrade your drive effortlessly.
Since we have established that storage health is often the hidden culprit, we recommend using AOMEI Partition Software. As a long-time user of this software, we consider it the "Swiss Army Knife" of Windows management. It goes far beyond the basic Windows Disk Management tool, offering advanced features to test disk speed, align partitions for SSD performance, and migrate OS without data loss.
A free and reliable disk partition software that helps you resize partitions, migrate OS, convert disks, and optimize PC efficiently.
Here is how to use AOMEI Partition Software to ensure your storage keeps up with your RAM.
Just like a RAM speed test, you need to know how fast your drive is reading and writing data.
The following are screenshots of the steps I personally tried to solve this problem:
Step 1. Download and install AOMEI Partition Software.
Step 2. Launch this tool, select the disk you wish to test, and click Disk Speed Test under the Test menu.
Step 3. All partitions will be listed here, and you can choose the one you want to test and click Start to start the process.
Step 4. Click "Start".
Step 5. Analyze Results: If your Random Read/Write speeds are very low (under 100 MB/s), your drive is the bottleneck, rendering your fast RAM useless.
If you have migrated to an SSD recently but didn't align it, it might be running slowly. AOMEI can fix this instantly.
Step 1. Right-click your SSD partition in AOMEI Partition Software.
Step 2. Select "Advanced" > "Partition Alignment".
Step 3. In the pop-up, set partition alignment to "4096 Sector" (This is the standard 4K alignment).
Step 4. Click OK. If it is already aligned, the software will tell you. If not, click Apply to execute. This simple step can increase SSD speed by 20-30%.
If you decide your current drive is too slow to do more optimizations and want to upgrade (the best way to complement high-speed RAM), AOMEI makes moving Windows easy without reinstalling everything. The software will move your Windows system to the ultra-fast drive. Restart your PC and change the boot order in BIOS.
If you are a gamer or overclocker, simply checking the "link speed" isn't enough. You need a benchmark. If you have used the methods above to how to check RAM on Windows 10 and want to push further, you aren't just looking for the frequency (MHz), but the latency and real-world bandwidth.
While Windows doesn't have a built-in stress test for speed (only for errors via mdsched.exe), you can use the logic of system monitoring.
Performance Monitor: Press Win + R, type perfmon, and enter. You can add counters for Memory to see how your RAM behaves under load.
Observation: Run a heavy game or rendering software. Open Task Manager. If your Memory usage hits 90-100% and your Disk usage spikes, your RAM is insufficient, and the computer is using the slow hard drive as "virtual RAM," killing your speed.
Knowing how to check RAM speed is an essential skill for modern PC maintenance. By using the Task Manager or Command Prompt, you can instantly verify if your memory is running at its advertised potential. However, keep in mind that a snappy computer relies on a balance between RAM and Storage.
If your RAM is up to spec but your system drags, the issue often lies with your storage drive. Tools like AOMEI Partition Assistant are invaluable here, allowing you to bridge the gap between hardware diagnostics and actual problem-solving—whether that means aligning your SSD for better speed or migrating to a high-performance drive to match your 2026 hardware standards.
Q1: Does RAM speed really matter for gaming in 2026?
A: Yes, but with diminishing returns. The jump from 2133 MHz to 3200 MHz (DDR4) or 4800 MHz to 6000 MHz (DDR5) offers a noticeable boost in FPS, especially in CPU-intensive games. However, beyond a certain point, lower latency (CL timings) matters more than raw speed.
Q2: My RAM says 3200 MHz on the box, but Task Manager says 2133 MHz. Why?
A: This is a very common issue. RAM runs at a standard "JEDEC" speed by default to ensure compatibility. To get the advertised speed, you must enter your BIOS/UEFI and enable XMP (Intel) or DOCP/EXPO (AMD).
Q3: How do I check how much RAM I have on a laptop?
A: The process is the same as a desktop. Press Ctrl + Shift + Esc to open Task Manager, go to Performance, and click Memory. It will show your total capacity (e.g., 16 GB) and how many slots are being used (e.g., 1 of 2), which helps you know if you can add more.
Q4: Can I mix different RAM speeds?
A: Technically, yes, but it is not recommended. If you mix a 3200 MHz stick with a 2666 MHz stick, your computer will force both to run at the slower speed (2666 MHz) to prevent crashing. It is always best to use matching kits.
Q5: Is 16GB of RAM enough for Windows 11?
A: 16GB is the new "sweet spot" standard. While Windows 11 can run on 8GB, it will struggle with modern multitasking and gaming. For heavy video editing or 4K gaming, 32GB is becoming the recommended amount.
