Reminiscence efficiency might be impacted by the Column Deal with Strobe (CAS) latency, which is a timing worth of random entry reminiscence (RAM). CAS latency, measured in nanoseconds (ns), determines how lengthy it takes for the reminiscence to reply to a learn or write request. Decrease CAS latency usually signifies sooner reminiscence efficiency. Understanding and optimizing CAS latency can improve system responsiveness and total efficiency, particularly for demanding purposes like gaming or content material creation.
In Home windows 11, checking CAS latency is an easy course of. The System Info software offers detailed details about your system {hardware}, together with RAM specs. To entry it, merely kind “System Info” into the search bar and choose the suitable outcome. Alternatively, you should utilize the keyboard shortcut Home windows Key + R, kind “msinfo32,” and press Enter. Within the System Info window, find the “Reminiscence” part. Underneath “Module Particulars,” you can find details about every reminiscence module put in in your system, together with its CAS latency.
After you have recognized the CAS latency of your RAM, you possibly can examine it to the specs supplied by the producer to make sure that your reminiscence is performing as anticipated. If the latency is larger than specified, it could point out a possible subject with the reminiscence or the system configuration. In such circumstances, consulting with the producer or a certified technician is really helpful to diagnose and resolve the underlying trigger.
Utilizing the Command Immediate for Superior Info
The Command Immediate provides a extra complete technique for retrieving RAM CAS latency info. This is how you should utilize it:
- Launch the Command Immediate as an administrator.
- Kind the next command and press Enter:
- Find the “ConfiguredClockSpeed” discipline within the output. This represents the RAM clock velocity in MHz.
- Divide the “ConfiguredClockSpeed” worth by 2 to acquire the RAM frequency in nanoseconds (ns).
- For double-rank RAM modules, divide the “ConfiguredClockSpeed” worth by 4 as an alternative.
- Calculate the CAS latency utilizing the next system:
- tCL: CAS Latency (normally discovered on the RAM module’s label or within the SPD knowledge)
- f: RAM frequency in nanoseconds (ns)
“`
wmic memorychip get BankLabel,Producer,SerialNumber,Capability,Pace,FormFactor,MemoryType,ConfiguredClockSpeed,ConfiguredVoltage
“`
“`
CAS Latency = Spherical((1000 * tCL) / f)
“`
For instance, in case your RAM module has a CAS Latency of 15 and a frequency of 1600MHz, the CAS Latency could be calculated as:
CAS Latency = Spherical((1000 * 15) / 1600) = 9.4
This means that the RAM module has a CAS Latency of 9.4 nanoseconds.
| Parameter | System |
|---|---|
| Clock Pace (MHz) | ConfiguredClockSpeed (from wmic command) |
| Frequency (ns) | ConfiguredClockSpeed / 2 (for single-rank RAM) |
| CAS Latency (ns) | (1000 * tCL) / f |
Leveraging Third-Occasion Software program for Detailed Evaluation
Whereas Home windows System Info offers primary CAS latency info, third-party software program instruments supply extra granular evaluation and extra insights into your RAM’s efficiency:
1. CPU-Z
CPU-Z is a well-liked and dependable utility that gives complete details about your system, together with detailed reminiscence specs. It shows CAS latency as a part of the “SPD” (Serial Presence Detect) tab below the “Reminiscence” part.
2. HWiNFO
HWiNFO is one other well-respected software that provides a wealth of system info, together with superior RAM particulars. It presents CAS latency in varied sections, such because the “Reminiscence Module” and “SPD” tabs.
3. Aida64
Aida64 is a complete diagnostic and benchmarking software that delves deep into your system’s intricacies. It offers detailed reminiscence info, together with CAS latency, in its “Reminiscence” part below the “SPD” tab.
4. MemTest86
MemTest86 is primarily a reminiscence testing software, however it additionally offers restricted system info, together with CAS latency. Entry this info by booting from the MemTest86 ISO or USB drive and deciding on the “Reminiscence Info” possibility.
5. PassMark MemTest86 Skilled
PassMark MemTest86 Skilled is a sophisticated model of MemTest86 that provides extra options and detailed reminiscence evaluation. Like MemTest86, it shows CAS latency as a part of its system info.
6. Essential Reminiscence Advisor
The Essential Reminiscence Advisor is an internet software that helps you discover appropriate reminiscence in your system. It offers detailed details about your present RAM, together with CAS latency, by analyzing your system specs.
7. System Info Viewer
System Info Viewer is a conveyable software that shows detailed system info, together with CAS latency. It presents this info in a structured desk format, making it straightforward to establish and analyze.
| Software program | CAS Latency Show |
|---|---|
| CPU-Z | SPD tab below Reminiscence |
| HWiNFO | Reminiscence Module and SPD tabs |
| Aida64 | Reminiscence part below SPD tab |
| MemTest86 | Reminiscence Info possibility |
| PassMark MemTest86 Skilled | System Info |
| Essential Reminiscence Advisor | Evaluation of system specs |

How To Test Ram Cas Latency On Home windows 11
RAM CAS latency, or Column Deal with Strobe latency, is a measure of how lengthy it takes for a reminiscence module to entry knowledge from a selected row. Decrease CAS latency means sooner entry occasions, which might enhance system efficiency, particularly in purposes that demand a excessive quantity of reminiscence bandwidth, equivalent to gaming, video modifying, and CAD.
To test the RAM CAS latency in your Home windows 11 system, comply with these steps:
1. Open the Process Supervisor by urgent Ctrl+Alt+Del and deciding on “Process Supervisor” or by looking for “Process Supervisor” within the Begin menu.
2. Within the Process Supervisor, choose the “Efficiency” tab.
3. Within the “Reminiscence” part, search for the “CAS Latency” row. The quantity listed subsequent to “CAS Latency” is the CAS latency of your RAM.
Individuals Additionally Ask About How To Test Ram Cas Latency On Home windows 11
What is an effective CAS latency for RAM?
For normal desktop purposes, a CAS latency of 16 or 18 is taken into account good. For gaming and high-performance purposes, a CAS latency of 14 or 12 is most popular.
How do I cut back RAM CAS latency?
