Serial presence detect (SPD)

Serial presence detect (SPD) is a feature of many computer memory modules that allows the module manufacturer to store information about the module on a small serial EEPROM chip. This information can include the module's size, speed, voltage requirements, timings, and other data.

When a memory module is inserted into a motherboard, the SPD EEPROM is read by the BIOS or operating system and used to configure the system for optimal operation with the module. SPD EEPROMs can also be used to store information about the module's manufacturer, part number, and other data.

What does SPD mean for RAM?

SPD (Serial Presence Detect) is a standard for identifying information about a memory module. This information includes the module's size, speed, voltage, timings, and other relevant data. SPD is used by the computer to properly configure the system for the installed memory. How do I check my memory SPD? There are a few ways to check your memory SPD. The most common way is to use a tool like CPU-Z or AIDA64 to read the SPD data from the memory modules. Alternatively, you can use a tool like memtest86+ to check the SPD data from the BIOS. Where is the serial number on a Micron SSD? The serial number on a Micron SSD can be found on the label on the top of the drive.

What does SPD mean in computers?

SPD, or Serial Presence Detect, is a technology used by some computer memory manufacturers to store information about their products in the form of a small serial EEPROM chip on the modules themselves. This information can include the module's manufacturer, model number, timing information, and other data. SPD is used primarily by system builders and motherboard manufacturers to automatically configure memory settings in the BIOS, which can save time and ensure compatibility.

What does SPD latency mean?

SPD latency is the delay between the time a signal is received by a device and the time that the device starts to process the signal. This delay can be caused by a number of factors, including the speed of the device's processors, the amount of time it takes for the device to receive the signal, and the time it takes for the device to start processing the signal.
