Why is my measured latency half as large as what the manufacturer specifies?
The measured latency may appear lower, especially if your system is running in "dual-channel mode".
In dual-channel mode, two memory channels share the work, sending data over two paths simultaneously. This effectively halves the time needed to transfer data compared to a single-channel system.
Lower latency means your memory responds to requests faster. This is especially beneficial for applications that require fast data access, such as gaming, video editing, or 3D rendering.
2.) Latency example for RAM modules:
If a RAM module operates with a latency of 40 nanoseconds
(ns) in single-channel mode, you can theoretically measure a latency of 20 ns
in dual-channel mode because both channels share the work.
3.) The deviations in the latency time:
There are a few factors that can affect the actual latency:
- System-related variations
Certain hardware components can cause slightly increased or decreased latency, such as the memory controller or the clock speed of the RAM.
- Power saving mode
When your laptop or PC is in power saving mode, the performance of the components can be reduced, which can lead to slightly increased latency.
It is important to make sure the computer is running in high performance mode when measuring latency to get accurate results.
