Enter the frequency and CAS latency of your RAM into the calculator to determine the RAM value in nanoseconds. This value helps in comparing the true latency of different RAM modules.
RAM Value Formula
The following formula is used to calculate the RAM value.
RAM Value (ns) = (CAS Latency / Frequency) * 1000
Variables:
- 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)
- Frequency is the speed at which the RAM operates (MHz)
To calculate the RAM value, divide the CAS latency by the frequency and then multiply the result by 1000 to convert it to nanoseconds.
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.
How to Calculate RAM Value?
The following steps outline how to calculate the RAM Value.
- First, determine the frequency at which the RAM operates (in MHz).
- Next, determine the CAS latency of the RAM (in cycles).
- Use the formula: RAM Value (ns) = (CAS Latency / Frequency) * 1000.
- Finally, calculate the RAM Value (in nanoseconds).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Frequency (MHz) = 3200
CAS Latency (cycles) = 16
