Socket & Chipset

The MSI X99S GAMING 7 uses the Intel X99 chipset and an LGA 2011-3 socket for Intel Core i7 processors. It fits an ATX form factor and supports four-channel DDR4 memory up to 128GB across a wide range of overclocked speeds. Four PCIe 3.0 x16 slots and two PCIe 2.0 x1 slots provide expansion for multi-GPU or add-in cards.

Sustained Load Behaviour

The board offers flexible PCIe lane allocation with 1-way, 2-way and 3-way modes that adapt to CPUs supporting up to 40 lanes. Storage throughput is handled by ten SATA III ports, one SATA Express interface and an M.2 slot running at 10Gb/s. Killer E2205 Gigabit LAN and six USB 3.0 ports maintain consistent data flow during extended sessions.

Thermals, Noise & Power

Realtek ALC1150 audio delivers 7.1 channel output with S/PDIF support for clean sound reproduction. The rear I/O includes two USB 3.0 and two USB 2.0 ports, while internal headers add four more of each standard. ASMedia ASM1042 chipset assistance helps manage peripheral connectivity without adding acoustic or thermal load.

Questions about this item

How loud and hot does the X99S GAMING 7 get when running 24/7?

The board uses passive chipset cooling and relies on your CPU cooler and case airflow; no onboard fan noise is added, but temperatures depend on the processor and chassis you pair with it.

Which DDR4 modules and CPU cooler mounting hardware do I need to make this LGA 2011-3 board POST?

You must supply four-channel DDR4 kits up to 128 GB and a cooler with LGA 2011-3 mounting holes; the box includes only the board, one SATA cable, I/O shield and CMOS battery.

Will my older PCIe 2.0 x1 sound card and SATA III SSD work in the x1 slots and SATA ports on this X99 board?

Yes — the two PCIe 2.0 x1 slots accept legacy add-in cards, and the ten SATA III ports plus one SATA Express connector support existing SATA SSDs and hard drives.
