What Is DRAM Frequency? How to Check It? What It Should Be Set? - MiniTool

This article will explain DRAM frequency and its impact on computer performance in an easy-to-understand manner, and guide you on how to view and adjust DRAM frequency.

What is DRAM frequency?

DRAM (Dynamic Random Access Memory) frequency refers to the amount of data transmitted by a data line per second. The actual measured value is about half the speed of RAM (random access memory) and can be adjusted according to computer needs.

Why is the DRAM frequency only half of the RAM frequency? This is because of the DDR (double data rate) technology. In many digital electronic devices, data transmission is synchronized with the clock. For example, if the CPU frequency is 5 GHz, the clock frequency is also 5 GHz. DDR technology allows data to be transmitted twice per cycle instead of once, thus doubling the frequency.

How to view DRAM frequency?

You can view the DRAM frequency by following the steps below:

Step 1: Visit the CPU-Z official website to download the software.

Step 2: Start CPU-Z and you will see the main menu containing the tabs such as CPU, cache, motherboard, memory, SPD, graphics card, workbench and about.

Step 3: Go to the Memory tab and you will see the Timing table. The DRAM frequency is displayed at the top of the timing box.

How to change DRAM frequency?

If you overclock, you may need to increase the DRAM voltage for better RAM stability. It should be noted that there are risks in adjusting DRAM, and excessive voltage may damage the device. The operation steps are as follows:

Step 1: After the machine starts, press the "Delete" key continuously until the BIOS loads.

Step 2: Click the "OC" button in the main BIOS menu and find the "Extreme Memory Profile (XMP)" option.

Step 3: Adjust the XMP option to "Profile 1" or select a profile that suits your RAM speed and timing.

Step 4: Save the changes and exit the BIOS. Use other software or CPU-Z to test speed and timing.

What should the DRAM frequency be set to?

Adjust the DRAM speed to the maximum speed allowed by RAM, or if the CPU cannot support the maximum speed of RAM, adjust the resonant speed allowed by the CPU.

If there is a problem, restore the DRAM to 1333 MHz and make sure the default voltage is 1.5V. While some people recommend setting DRAM to 1600 MHz, the benefits are minimal relative to potential risks.

Different generations of DRAM frequency ranges:

• DDR1 frequency range – 200-400 MHz
• DDR2 frequency range – 400-1066 MHz
• DDR3 frequency range – 800-2133 MHz
• DDR4 frequency range – 1600-5333 MHz
• DDR5 frequency range – 3200-6400 MHz
• DDR6 Frequency Range – DDR6 has not been officially released yet, but it is expected to be at least twice as fast as DDR5.
