RAM Latency Calculator

Find the true latency of RAM in nanoseconds.

Latency (ns) 10

Formula: latency = CL * 2000 / speed

Step-by-step with your numbers:
1. Values used:
2. CAS latency (CL) = 16
3. Memory speed = 3,200 MT/s
4.
5. Latency = 10ns
Did we solve your problem today?

True RAM latency combines the CAS latency with the clock speed.

The math behind it

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

Worked example

CL16 at 3200 MT/s gives 10 ns.

FAQ

Is lower CL always better?

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