What is tested latency?
A latency test measures the amount of time needed to move data messages from one point within a computer network to another. Latency times are usually measured in nanoseconds.
What does SPD mean in RAM?
serial presence detect
When a computer is booted (started), serial presence detect (SPD) is information stored in an electrically erasable programmable read-only memory (EEPROM) chip on a synchronous dynamic random access memory (SDRAM) memory module that tells the basic input/output system (BIOS) the module’s size, data width, speed, and …
How do you perform a latency test?
Open a command window by clicking the Windows start button, or hitting the Windows key, and typing in cmd then hitting enter. In the results above, we’re looking for the values after time= which shows the latency between your computer and your server in milliseconds(ms).
What is tested latency on RAM?
A RAM module’s CAS (Column Address Strobe or Signal) latency is how many clock cycles in it takes for the RAM module to access a specific set of data in one of its columns (hence the name) and make that data available on its output pins, starting from when a memory controller tells it to.
What does the SPD chip do?
The SPD (Serial Presence Detect) chip on a memory module is an additional chip holding 128Hex bytes of information about the module. This identifies the module to the BIOS during POST so the Motherboard knows its characteristics and timings that can be used. This was introduced at the same time as SDRAM.
How do I check my ping and latency?
Is latency and ping the same?
What is latency? While the ping is the signal that’s sent from one computer to another on the same network, latency is the time (in milliseconds) that it takes for the ping to return to the computer. So latency is a measurement of the entire round trip of that signal while ping is just one way.
