This 8GB RAM is 100% compatible with the Tyan S5532 (S5532WGM2NR-LE). For assistance in selecting the right RAM, we offer faster 1600MHz memory for your system. Due to the backward compatibility of our RAM to 1333MHz, you can also mix it with existing 1333MHz memory. ECC memory provides greater security through error detection and correction. The ECC function is supported if all existing memory is equipped with ECC. You should use UDIMM ECC RAM if existing memory is already ECC-equipped. Using different RAM sizes in the slots is possible. The Dual Channel Mode is also supported by Intel's Flex Memory Technology. When using different RAM capacities, ensure that the memory in Memory Channel A is larger than the memory in Memory Channel B.
