Your PC’s RAM timings affect system performance more than most people realize. If you want to tweak performance, troubleshoot issues, or just understand what your memory modules are doing, it helps to know how to check timings like CAS Latency (CL), tRCD, tRP, and tRAS. This guide walks you through several simple methods — no guesswork required.
What Are RAM Timings? (Quick Overview)
RAM speed (MHz) tells you how fast your memory clock runs.
RAM timings tell you the latency (delay in cycles) for different memory operations.
Lower timings = faster response (at the same MHz).
Common primary timings include:
CL (CAS Latency)
tRCD (RAS to CAS Delay)
tRP (Row Precharge Time)
tRAS (Row Active Time)
Ways to Check RAM Timings in Windows 11
There’s no single “RAM timings” button in Windows, but you can use built-in tools and free software.
Method 1 — Use Task Manager (Basic Info Only)
Press Ctrl + Shift + Esc to open Task Manager.
Go to the Performance tab.
Click Memory.
Here you’ll see memory speed (MHz), slots used, and total capacity — but not detailed timings.
👉 Use this as a quick speed check; move on for detailed timings.
Method 2 — Use Command Prompt with WMIC (Limited Details)
Press Windows + S, type
cmd, and choose Run as administrator.Enter the command:
You’ll see memory speed and part numbers — helpful, but still no full timings.
Method 3 — Use PowerShell (More Detailed)
Press Windows + X, then select Windows Terminal (Admin) or PowerShell (Admin).
Run:
This shows speed and manufacturer data. Still limited on timings, but useful.
Method 4 — Use Third-Party Tools (Best Method)
For full RAM timings (CL, tRCD, tRP, tRAS, etc.), third-party tools are the way to go.
Option A — CPU-Z (Free and Easy)
Download CPU-Z (official site).
Install and launch it.
Go to the Memory tab.
You’ll see DRAM Frequency and detailed timings (CL, tRCD, tRP, tRAS).
Option B — HWiNFO (More Advanced)
Download and install HWiNFO.
Run it in Sensors-only mode.
Expand the memory section — you’ll find live RAM timings, frequency, and voltage.
Method 5 — Check BIOS/UEFI (Advanced Users)
Restart your PC.
Press the firmware key (usually Del, F2, or Esc) to enter BIOS/UEFI.
Go to the Advanced / Overclock / Memory settings section.
Look for DRAM Configuration — timings will be listed there.
👉 Best for when you want to adjust RAM timings manually (overclocking).
Which Method Should You Use?
Quick check: Task Manager.
Part numbers & speed only: Command Prompt / PowerShell.
Detailed timings: CPU-Z (best for most users).
Advanced monitoring: HWiNFO.
Tweaking timings: BIOS/UEFI.
FAQs
Q1: Why should I care about RAM timings?
A: Lower timings can improve responsiveness, especially in gaming or memory-heavy workloads.
Q2: Can I change RAM timings in Windows 11?
A: No — you can only view them in Windows. To change timings, you must use BIOS/UEFI.
Q3: Are lower timings always better?
A: Generally yes, but they must be stable. Pushing timings too low can cause crashes.
Q4: What if my tool shows two different speeds (e.g., 1600 MHz and 3200 MHz)?
A: DDR (Double Data Rate) memory doubles its base clock. CPU-Z shows base frequency (e.g., 1600 MHz), which equals DDR4-3200.
Q5: Which is more important — MHz or timings?
A: Both matter. Higher MHz = bandwidth, lower timings = lower latency. The best RAM has a balance.
✅ Final Tip: For most users, CPU-Z is the easiest way to see full RAM timings on Windows 11 without hassle. If you’re into tweaking, BIOS is where you make changes.
