Gigabyte X99-UD3 Motherboard

Memory Support

Intel socket LGA2011-v3 CPUs have an embedded memory controller, meaning that it is the processor, not the chipset, which defines what memory technologies you can have and the maximum amount of memory that is possible. The motherboard, however, may have a limitation as to how much memory can be installed.

The integrated memory controller from socket LGA2011-v3 processors officially supports DDR4 memories up to 2,133 MHz. According to Gigabyte, the X99-UD3 supports memories up to 3,000 MHz.

One of the most important features of the socket LGA2011-v3 processors is the support for the quad-channel memory architecture, which allows the memory to be accessed in 256-bit mode for higher performance. Since each memory module is a 64-bit entity, four memory modules are needed to enable this architecture. If only two or three memory modules are installed, the memory will be accessed under dual- or triple-channel architecture, respectively.

The Gigabyte X99-UD3 has four memory sockets (two at each side of the CPU socket) and you can have up to 32 GiB with this motherboard if you use four 8 GiB modules.

In order to enable the quad-channel mode, you must install four identical memory modules.
