Dram Speed Calculator

A DRAM Speed Calculator helps determine the effective data transfer rate of Dynamic Random Access Memory (DRAM). This is crucial for understanding the performance of RAM modules used in computers, servers, and other electronic devices. By inputting the base clock frequency, the calculator provides the effective transfer rate in Megatransfers per second (MT/s), which is essential for comparing memory performance.

Formula of Dram Speed Calculator

The effective transfer rate of DRAM is calculated using the following formula:

Effective Transfer Rate (MT/s) = Base Clock Frequency (MHz) × Multiplier

Where:

• MT/s stands for Megatransfers per second
• Base Clock Frequency is the fundamental clock speed of the memory (MHz)
• Multiplier depends on the DDR generation:
  • DDR: 2
  • DDR2: 2
  • DDR3: 2
  • DDR4: 2
  • DDR5: 2

General DRAM Speed Table

Below is a table with common DRAM speeds based on base clock frequencies and their DDR multipliers:

This table helps users quickly reference DRAM speeds without manually calculating each value.

Example of Dram Speed Calculator

Suppose you have a DDR4 memory module with a Base Clock Frequency of 1600 MHz. To calculate the Effective Transfer Rate:

Effective Transfer Rate = 1600 MHz × 2 = 3200 MT/s

This means the DRAM module operates at 3200 Megatransfers per second, often labeled as DDR4-3200.
