ECC stands for ERROR CORRECTING CODE.
This uses technology on the motherboard to test the accuracy of outgoing and incoming data by using a checksum. Some errors are automatically corrected; ECC modules are normally used in high end workstations and servers where data integrity is vital. ECC applies to DDR3, DDR4 and DDR4 modules.
ECC modules have a extra memory chip for every eight chips. e.g. 9 or 18 as opposed to 8 or 16 for a NON-ECC module.
In most cases you can install a ECC module into a NON-ECC system but generally a ECC system will require a ECC module. Please check your PC manual.
