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

What Is DRAM Frequency?

DRAM (Dynamic Random Access Memory) frequency is the percentage of data transferred per second on the data wire. Actual measurements are about half the speed of the RAM (random-access memory) and can be adjusted up or down depending on the needs of the PC.

Why DRAM is only half the frequency of your RAM? The reason for this is DDR (double data rate). In many digital electronic devices, data transmission is synchronized with this clock. For example, if the CPU has 5 GHz, then the clock is also 5 GHz. With DDR, you can transfer data twice per cycle instead of once. Because of this, you get double the frequency.

How to Check DRAM Frequency?

How to check DRAM frequency? Follow the guide below:

Step 1: Go to CPU-z’s official website and download it.

Step 2: Launch it and you’ll see the main menu with tabs that include CPU, Cache, Motherboard, Memory, SPD, Graphics, Workbench, and About.

Step 3: Go to the Memory tab and you will see the Timings table. At the top of the Timings box is the DRAM frequency.

How to Change DRAM Frequency?

If you are overclocking, you may want to increase the DRAM voltage to provide better ram consistency. It’s important to note that tuning DRAM can be risky since excessive voltage increases may damage your device. Here is how to do that:

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

Step 2: Click the OC button on the main BIOS menu. Find the Extreme Memory Profile (XMP) option.

Step 3: Adjust the XMP option to Profile 1 or choose the one that suits the speed and timing of your RAM.

Step 4: Exit the BIOS after saving the changes. Use other software or CPU-z to test speed and timing.

What Should the DRAM Frequency Be Set to?

Tune your DRAM speed to the maximum speed your RAM allows, or, if our CPU can’t accept the maximum speed of your ram, tune it to the resonant speed your CPU allows.

If something goes wrong, you should change the DRAM back to 1333 MHz and make sure the default voltage is 1.5V. Some people on the internet will say that running DRAM at 1600 MHz is the right move, but the benefits are certainly few compared to the possible risks.

DRAM Frequency by Generation

• 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 yet to be officially announced but is expected to at least double up on the speeds offered by DDR5, whenever it happens.
