Intel socket LGA1155 CPUs have an embedded memory controller, meaning that it is the processor – and not the chipset – that defines what memory technologies and the maximum amount of memory you can have. The motherboard, however, may have a limitation as to how much memory can be installed.
The integrated memory controller from socket LGA1155 processors supports only DDR3 memories up to 1,333 MHz under dual-channel architecture, but Biostar says the TP67XE supports memory up to 2,133 MHz through overclocking.
The Biostar TP67XE has four memory sockets and, since currently DDR3 memory modules can be found in capacities up to 4 GB, you can have up to 16 GB with this motherboard, if you use four 4 GB modules.
The first and third sockets are red, while the second and fourth are white. In order to achieve the maximum performance you should install two or four memory modules in order to enable dual-channel architecture. When only two modules are used, install them in the red sockets, otherwise your computer won’t turn on.
