Socket and Chipset

The MSI X99S SLI PLUS motherboard uses the Intel X99 chipset and an LGA 2011-3 socket. It is built for new generation Intel Core i7 processors. The board targets enthusiasts who need high core counts and quad-channel memory bandwidth.

Compatibility Check

Verify that your CPU fits the LGA 2011-3 socket and that your memory kit is DDR4 rated for 2133 MHz or higher. The board accepts up to 128 GB across four channels. Confirm your case can fit an ATX form factor and that your power supply provides the necessary 24-pin and CPU EPS connectors.

Thermals Noise Power

The chipset and voltage regulators are cooled by passive heatsinks so they add no fan noise. Under typical loads the board draws modest power beyond the CPU itself. The Realtek ALC892 audio codec and Intel I218 LAN controller operate well within their thermal limits without active cooling.

Questions about this item

What accessories are included in the box and what must be purchased separately?

The box contains the motherboard, a CMOS battery, one SATA cable and the chassis I/O back panel. A Wi-Fi antenna is included only if the board has a built-in Wi-Fi module. CPU, memory, storage and any additional cables must be bought separately.

Which DDR4 speeds can I choose to reach the 128 GB limit?

The board supports four-channel DDR4 at 2133 MHz natively and up to 3333 MHz when overclocked. Populating all four slots with DDR4 modules allows the full 128 GB capacity regardless of the chosen speed grade.

How do the PCIe 3.0 x16 slots behave when I install two graphics cards?

In 2-way mode the first two slots run at x16 and x16, or at x16 and x8 depending on the CPU lane count. The remaining two x16 slots stay inactive, while two PCIe 2.0 x1 slots remain available for add-in cards.
