ASRock Fatal1ty X99M Killer Motherboard
Slots
Contents
Socket LGA2011-v3 processors have a maximum of 40 PCI Express 3.0 lanes (some models have only 28 lanes) for video cards. This allows a very high-end configuration for the PCI Express x16 slots when a CPU with 40 lanes is installed, but the exact configuration used will depend on the model of the CPU that will be installed.
The ASRock Fatal1ty X99M Killer comes with two PCI Express 3.0 x16 slots, both of them working always at x16 mode if a 40 lane processor is used, and at x16/x8 if a CPU with 28 lanes is installed, and one PCI Express 2.0 x16 slot (working at x4).
The motherboard supports SLI arrays, and CrossFireX with up to two video cards.
There is also an M.2 slot, which is compatible with PCI Express 3.0 x4 and SATA M.2 modules.
