RAM Latency Calculator

Find the true latency of RAM in nanoseconds.

Calculated Output

Latency (ns) 10

Formula: latency = CL * 2000 / speed

Step-by-Step Breakdown

1. Values used:

2. CAS latency (CL) = 16

3. Memory speed = 3,200 MT/s

5. Latency = 10ns

Did this calculator solve your problem today?

The math behind it

latency (ns) = CL x 2000 / speed (MT/s), since DDR transfers twice per clock cycle.

CL16 at 3200 MT/s gives 10 ns.

Is lower CL always better?

Only at the same speed - faster RAM with higher CL can still have lower ns latency.
