RAM Latency Calculator

Formula

The formula to calculate RAM Latency is:

\[ \text{RL} = \frac{\text{CL} \times 2000}{\text{DR}} \]

Where:

\(\text{RL}\) is the RAM latency (nanoseconds)
\(\text{CL}\) is the CAS latency (CL)
\(\text{DR}\) is the data rate (MHz)

What is RAM Latency?

RAM latency is the time it takes for the RAM module to access a set of data in one of its columns. It is measured in nanoseconds and is calculated by multiplying the CAS latency by 2000 and then dividing by the data rate. Lower RAM latency is better as it indicates faster performance.

Example Calculations

Example 1:

CAS Latency (CL): 16
Data Rate (DR): 3200 MHz

Using the formula:

\[ \text{RL} = \frac{16 \times 2000}{3200} = 10 \text{ nanoseconds} \]

Example 2:

CAS Latency (CL): 18
Data Rate (DR): 3600 MHz

Using the formula:

\[ \text{RL} = \frac{18 \times 2000}{3600} = 10 \text{ nanoseconds} \]
