RAM Latency Calculator - How to check my ram speed?

Our ram latency calculator will help you calculate RAM latency in nanosecods after inputting ram speed in Mhz and CL timing. You can find information about RAM frequency and CL timing on labels stuck on RAMs or the product page for RAM on any ecommerce store where you buy RAMs.

How to find out RAM speed / frequency and cas latency / cl timing

The result in nanoseconds =

The lower the time in (Ns) the faster the RAM is.

How does an online RAM Latency Calculator work?

~ Step 1 ~

Enter the RAM speed/frequency in megahertz (MHz). This is basically how much data that your RAM can send and receive from your CPU.

~ Step 2 ~

Consider CAS delay. This is CAS latency, which is frequently mentioned when acquiring RAM for a computer.

~ Step 3 ~

The calculator will compute RAM latency in nanoseconds for this sample. The less the delay, the better it is.

What Is RAM Latency?

RAM latency is the amount of time it takes the memory controller to deliver a command to the RAM and load data. However, CAS latency (e.g. CL16-18-18-36) in RAM standards only indicates the total cycles, not their length in ns.

The CAS (Column Address Strobe or Signal) latency of a RAM module is the number of clock cycles that the RAM module takes in order to access a specific data set in any of its columns (which explains the name) and make that data available on its output pins, beginning when a memory controller instructs it to.

In general, the faster the access time, the lower the latency. However, if the access time is too high, then the system may not have enough bandwidth to transfer the data fast enough. You can use an online ram calculator in order to calculate the latency of your RAM.

Formula for calculating RAM latency

After entering ram speed in MHZ and CL timing, a latency calculator will determine delay in nanoseconds.

Our Ram latency calculator is using this formula
RAM latency = (2000 x CL) / rating

RAM Performance vs. Latency

Memory speed (or data rate) refers to how quickly your memory controller can write or read data to memory. On the other hand, RAM latency refers to how quickly it can begin the operation.

Memory speed is measured in Mega transfers per second (MT/s), whereas the latency is measured in nanoseconds.

All of it is based on the situation. Latency is the time it takes for the RAM controller and internal circuitry to complete the request; "speed" is how quickly the bytes can be returned once the data is accessible, and how many bytes may be retrieved with no additional latency penalty.

RAM Latency and Computer Games

For any game with a core data set larger than the CPU's cache system can hold, latency directly affects frame times - any object that must to be checked for render calls and any object which is impacted by physics, player actions, or AI needs to be loaded from RAM with every single frame drawn, and each of these actions will have the CPU waiting on the RAM for the duration. However, when FPS objectives increase and frame time targets decrease, latency begins to become an issue. Too much RAM latency might result in skipped frames (-> continuous stuttering) and severely limit the FPS of a high-end GPU.

How does RAM latency affect performance?

The higher the RAM latency, the slower the performance of a computer is. If the RAM latency is too high, then it will take longer for the processor to read the data from the RAM. As a result, the processor will spend more time waiting for the data to arrive, which means less time spent processing instructions.

Can rams with different latencies be combined?

You can combine RAM with varying latency, but the higher latency RAM will operate at the same speed as the RAM with lower latency. Although it is possible, it is not recommended. When feasible, you should aim to utilize identical memory chips.

What is a Ram Comparison Calculator?

A Ram Comparison Calculator is a tool that helps you compare different rams based on their physical characteristics. You enter the information about each ram and then click calculate to get a list of the results. These results give you a quick overview of how similar or dissimilar two rams are.

To use such a tool, first of all you need to know what kind of ram you want. Then you enter the information about the rams into the calculator. After that, you click calculate to get a result. If you want to find out more details about the ram, you can click on the link at the bottom of the page.

These tools help you make informed decisions about buying a RAM. By comparing the features of different rams, you can choose the best RAM for your specific needs.

How to Measure RAM Latency?

How to Measure RAM Latency?

You can start by installing a freeware that offers all kinds of helpful information on your computer's hardware, including the RAM’s CAS Latency speed. It is by far the simplest approach. To determine the RAM’s CAS Latency speed, perform these steps:
  1. Download the CPU-Z installer and install it after the download is complete. Installation instructions may be found on the official website.
  2. Once the installation is complete, open the program and go to the memory tab.
  3. CAS Latency, along with other information about the timing, should be specified in the Timing box. The number that is displayed therein should be expressed in clock cycles.
How to Test RAM Speed and Frequency?

How to Test RAM Speed and Frequency?

RAM speed or DRAM frequency are other terms for RAM clock speed. If you use Windows, you can simply determine your RAM clock speed with utilizing the task manager software.
  1. Launch Task Manager (ctrl+shift+esc) (ctrl+alt+del)
  2. Select Performance / Memory
