PHS-memory RAM suitable for MSI Gaming Z87-G45

This 4GB RAM is 100% compatible with the MSI Gaming Z87-G45. We offer you faster 1600MHz memory for your system. Thanks to the backward compatibility of our memory at 1333MHz, you can also mix it with existing 1333MHz modules. ECC memory provides higher security through error detection and correction. The ECC function is supported when all existing memory is equipped with ECC. You should use UDIMM ECC memory if the existing modules are ECC-equipped. It is possible to use different RAM sizes in the slots. Dual Channel Mode is also supported by Intel Flex Memory Technology in this case. When using different memory capacities, you need to ensure that the modules in Memory Channel A are larger than the modules in Memory Channel B.
