FAQ
What is the capacity and configuration of this Patriot Memory module?
This is a single 16GB DDR4 SODIMM module (1 x 16GB configuration). It provides 16 gigabytes of total memory capacity as one physical module, which is ideal for notebooks with one available memory slot or for replacing an existing module in a single-slot system.
What speed and DDR generation does this memory support?
The module operates at 2666 MHz, which corresponds to the DDR4-2666 standard (also labeled as PC4-21300). It uses DDR4 SDRAM technology, offering higher bandwidth and improved power efficiency compared to previous DDR3 generations, while maintaining compatibility with systems designed for DDR4 memory.
Is this memory ECC or non-ECC, and what does that mean for my notebook?
This is a non-ECC (Error-Correcting Code) unbuffered module. Non-ECC memory does not include extra circuitry to detect and correct memory errors, which is standard for most consumer and business notebooks. It offers lower latency and cost compared to ECC memory, making it suitable for general computing, office workloads, and multimedia applications where extreme data integrity is not required.
What form factor and pin count does this module have?
This module uses the SODIMM (Small Outline Dual In-line Memory Module) form factor with a 260-pin interface. SODIMMs are specifically designed for notebooks and other compact systems. The 260-pin count is standard for DDR4 SODIMMs, ensuring physical and electrical compatibility with laptop memory slots that support DDR4 technology.
What is the CAS latency and operating voltage?
The module has a CAS latency of CL19 and operates at 1.20 volts. CAS latency (CL19) indicates the number of clock cycles needed to access a column of data, with lower numbers generally being faster. The 1.20V operating voltage is standard for DDR4 memory, providing power efficiency benefits for battery-powered notebooks compared to older DDR3 modules that typically used 1.35V or 1.50V.
Which notebooks are compatible with this memory module?
This module is compatible with notebooks that support DDR4 SODIMM memory at 2666 MHz (PC4-21300) with non-ECC, unbuffered specifications. Compatibility depends on the specific laptop model, chipset, and CPU. Always verify your notebook's maximum supported memory speed, capacity per slot, and DDR generation before purchase. The module is designed for systems with standard 260-pin SODIMM slots and typically works with many Intel 8th/9th/10th/11th Gen and AMD Ryzen-based laptops that accept DDR4-2666 memory.
