FAQ's
Is the HMA851S6JJR6N-VK compatible with DDR3 systems? No, this module is DDR4 memory and is not compatible with DDR3 systems, as they use different signaling and form factors. What does CL19 mean on this memory module? CL19 refers to the CAS latency timing, indicating the delay in clock cycles between a command and the moment data is available. For this module, the latency is 19 clock cycles. Can this 4GB module be used in desktop computers? This module uses the SODIMM form factor, which is designed for laptops and compact systems, so it is generally not compatible with standard desktop DIMM slots. Does this memory module support error correction? No, the HMA851S6JJR6N-VK is non-ECC memory, meaning it does not have error-correcting capabilities and is intended for systems that do not require ECC. What devices typically use this SK Hynix memory module? This 4GB DDR4-2666 SODIMM is typically used in laptops, small form-factor PCs, and embedded systems that require DDR4 memory upgrades within the specified speed and latency. Is any special configuration needed to install this module? Installation involves standard SODIMM memory installation procedures without additional configuration, provided the target system supports DDR4-2666 SODIMM modules.
