Frequently Asked Questions
What is ECC memory and why do I need it?
ECC (Error-Correcting Code) memory detects and automatically corrects single-bit memory errors that can occur during normal operation. This is essential for servers, workstations, and systems handling critical data where memory errors could cause data corruption or system crashes. The Samsung DDR4 ECC SO-DIMM provides this protection in a compact laptop-friendly format.
Is this 16GB DDR4 SO-DIMM compatible with my laptop?
The M474A2K43BB1-CTD uses the standard 260-pin SO-DIMM form factor and operates at 2666MHz DDR4 speeds. Compatibility depends on your system's memory slot type and supported speeds. Check your laptop or workstation's specifications to confirm DDR4 SO-DIMM support and maximum memory capacity before upgrading.
What systems use PC4-21300 2666MHz memory?
PC4-21300 refers to the 2666MHz speed rating for DDR4 memory. This speed is commonly found in mobile workstations, business laptops, compact servers, and professional-grade systems from manufacturers like Dell, HP, Lenovo, and others that support DDR4 ECC memory modules.
How does the 1.2V operating voltage benefit my system?
The 1.2V standard voltage for DDR4 memory reduces power consumption compared to older DDR3 modules, lowering overall system energy use and heat output. This is particularly beneficial in laptops and compact systems where thermal management and battery life are important considerations.
