Intel X99 platform board

This MSI motherboard uses the Intel X99 chipset and an LGA 2011-v3 socket for Core i7 Extreme Edition processors. It targets enthusiasts building high-end desktop systems that need quad-channel DDR4 memory and multi-GPU capability. The board supports up to 128 GB of RAM across eight slots.

Quad-channel DDR4 and flexible PCIe

Four full-length PCIe 3.0 x16 slots run at x16, x16/x16 or x16/x16/x8 depending on how many cards are installed. Two additional PCIe 2.0 x1 slots provide room for add-in controllers. Ten SATA III ports, one SATA Express connector and one M.2 interface give extensive storage options.

Intel gigabit LAN and Realtek audio

A single Intel I210-AT controller handles wired networking at gigabit speeds. The Realtek ALC1150 codec delivers 7.1-channel high-definition audio with S/PDIF output. Six USB 3.0 ports and six USB 2.0 ports are split between the rear panel and internal headers for front-panel connectivity.

Questions about this item

What DDR4 speeds can the X99S SLI Krait Edition actually run?

The board supports four-channel DDR4 at 2133, 2200, 2400, 2600, 2666, 2750, 3000, 3110 and 3333 MHz; speeds above 2133 MHz require overclocking.

How much space does this Micro ATX board need inside the case?

It fits any chassis with Micro ATX or larger mounting holes and uses the standard ATX I/O shield supplied in the box.

What is the first step when installing this motherboard, and what do builders often skip?

Fit the I/O shield into the case before seating the board; skipping it forces a full teardown to add it later.
