Gigabyte Z68X-UD3H-B3 Motherboard

Memory Support

Intel socket LGA1155 CPUs have an embedded memory controller, meaning that it is the processor, 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 Gigabyte says the Z68X-UD3H-B3 supports memory up to 2,133 MHz through overclocking.

The Gigabyte Z68X-UD3H-B3 has four memory sockets, and since DDR3 memory modules can now be found in capacities up to 8 GB, you can have up to 32 GB with this motherboard if you use four 8 GB modules.

All memory sockets are black, which is a big drawback, because in order to enable dual-channel technology (which increases memory performance), you need to install one memory module in the first socket and one memory module in the third socket. In other words, you should not install memory modules in any socket you want.
