WHAT IS THE PERFORMANCE DIFFERENCE BETWEEN ECC, PARITY AND NON-ECC, NON-PARITY?
ECC (error checking and correcting) memory performs double bit detection and single bit correction. This means that if you have a single bit memory error, the chipset and memory will find and repair the error on the fly without you knowing that it happened. If you have a double bit memory error, it will detect and report it. Non-ECC, non-parity memory, on the other hand, has no error detection and correction capabilities. Using ECC decreases your PC s performance by about 2%. Current technology DRAM is very stable and memory errors are rare, so unless you have a need for ECC, you are better served with non-ECC, non-parity memory.
