FAQ's
What does CL19 signify in this memory module? CL19 refers to the CAS latency, indicating the delay between a memory request and the data being available. A CL19 latency means the module has 19 clock cycles delay, balancing speed and responsiveness for DDR4-2666 memory. Is this module compatible with non-ECC systems? This memory module is designed for systems supporting ECC and registered DIMMs, typically servers and workstations. It is generally not compatible with non-ECC desktop systems that do not support registered ECC memory. What is the benefit of the registered DIMM (RDIMM) form factor? The RDIMM design includes a register between the memory controller and DRAM modules, reducing electrical load and improving signal integrity, which enhances stability in multi-module server configurations. Can this memory be used in standard desktop PCs? No, this module is an ECC registered DIMM intended for servers and workstations. Standard desktop PCs typically use unbuffered, non-ECC memory modules, so this module would not be compatible. Does SK Hynix manufacture this memory module? Yes, the HMA81GR7CJR8N-VKT3AD is manufactured by SK Hynix, known for producing DRAM modules for enterprise and consumer markets. What environments benefit most from ECC memory? Environments such as servers, professional workstations, and data centers benefit from ECC memory because it helps detect and correct data errors, reducing system crashes and data corruption.
