RAM Value Calculator

Formula

The formula to calculate the RAM value is:

\[ \text{RAM Value (ns)} = \left( \frac{\text{CAS Latency}}{\text{Frequency}} \right) \times 1000 \]

Where:

\(\text{CAS Latency}\) is the number of cycles it takes for the RAM to access a specific set of data in one of its columns (cycles)
\(\text{Frequency}\) is the speed at which the RAM operates (MHz)

What is RAM Value?

RAM value, often referred to as true latency, is a measure of the actual delay or latency of RAM in nanoseconds. It is a more accurate representation of RAM performance than just frequency or CAS latency alone. Lower RAM value indicates better performance as it means less time is taken to access data.

Example Calculation

Let's assume the following values:

CAS Latency = 16 cycles
Frequency = 3200 MHz

Using the formula to calculate the RAM value:

\[ \text{RAM Value (ns)} = \left( \frac{\text{CAS Latency}}{\text{Frequency}} \right) \times 1000 = \left( \frac{16}{3200} \right) \times 1000 \approx 5 \text{ ns} \]

The RAM value is approximately 5 ns.
