Reminiscence efficiency might be impacted by the Column Tackle 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 typically signifies sooner reminiscence efficiency. Understanding and optimizing CAS latency can improve system responsiveness and general efficiency, particularly for demanding purposes like gaming or content material creation.
In Home windows 11, checking CAS latency is a simple course of. The System Info device supplies 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 consequence. Alternatively, you should use the keyboard shortcut Home windows Key + R, kind “msinfo32,” and press Enter. Within the System Info window, find the “Reminiscence” part. Underneath “Module Particulars,” one 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 may evaluate it to the specs offered by the producer to make sure that your reminiscence is performing as anticipated. If the latency is greater than specified, it might point out a possible problem with the reminiscence or the system configuration. In such circumstances, consulting with the producer or a certified technician is really useful to diagnose and resolve the underlying trigger.
Utilizing the Command Immediate for Superior Info
The Command Immediate presents a extra complete technique for retrieving RAM CAS latency data. This is how you should use 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 pace 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 a substitute.
- Calculate the CAS latency utilizing the next components:
- tCL: CAS Latency (often discovered on the RAM module’s label or within the SPD information)
- 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-Get together Software program for Detailed Evaluation

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 underneath the “Reminiscence” part.
2. HWiNFO
HWiNFO is one other well-respected device that gives a wealth of system data, together with superior RAM particulars. It presents CAS latency in numerous sections, such because the “Reminiscence Module” and “SPD” tabs.
3. Aida64
Aida64 is a complete diagnostic and benchmarking device that delves deep into your system’s intricacies. It supplies detailed reminiscence data, together with CAS latency, in its “Reminiscence” part underneath the “SPD” tab.
4. MemTest86
MemTest86 is primarily a reminiscence testing device, but it surely additionally supplies restricted system data, together with CAS latency. Entry this data by booting from the MemTest86 ISO or USB drive and choosing the “Reminiscence Info” choice.
5. PassMark MemTest86 Skilled
PassMark MemTest86 Skilled is a complicated model of MemTest86 that gives extra options and detailed reminiscence evaluation. Like MemTest86, it shows CAS latency as a part of its system data.
6. Essential Reminiscence Advisor
The Essential Reminiscence Advisor is an internet device that helps you discover suitable reminiscence on your system. It supplies 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 device that shows detailed system data, together with CAS latency. It presents this data in a structured desk format, making it straightforward to determine and analyze.
| Software program | CAS Latency Show |
|---|---|
| CPU-Z | SPD tab underneath Reminiscence |
| HWiNFO | Reminiscence Module and SPD tabs |
| Aida64 | Reminiscence part underneath SPD tab |
| MemTest86 | Reminiscence Info choice |
| PassMark MemTest86 Skilled | System Info |
| Essential Reminiscence Advisor | Evaluation of system specs |

How To Verify Ram Cas Latency On Home windows 11
RAM CAS latency, or Column Tackle Strobe latency, is a measure of how lengthy it takes for a reminiscence module to entry information 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, reminiscent of gaming, video enhancing, 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 choosing “Process Supervisor” or by trying to find “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 Verify 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 well-liked.
