Step 1: Go to CPU-z's official website and download it. How to check DRAM frequency? Follow the guide below: SDRAM VS DRAM: What Is the Difference Between Them?.SRAM VS DRAM: What Is the Difference Between Them?.Because of this, you get double the frequency.
With DDR, you can transfer data twice per cycle instead of once. For example, if the CPU has 5 GHz, then the clock is also 5 GHz. In many digital electronic devices, data transmission is synchronized with this clock.
Why DRAM is only half the frequency of your RAM? The reason for this is DDR (double data rate). 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.
