The Aorus Ultra Gaming represents Gigabyte's upper tier platform for High-End Desktop Processors from the Skylake-X and Kaby Lake-X generations that utilise the X299 chipset and demand a LGA2066 socket. This chipset, codenamed "Lewisburg", is notable for its up to 30 HSIO lanes (High- Speed Input/Output) as well as the maximum usable number of 24 PCIe Express 3.0 lanes.

The Gigabyte Aorus Ultra Gaming is a premium enthusiast motherboard using the ATX format and is designed for hardware enthusiasts and professionals looking for a X299- & Skylake-X or Kaby- Lake X pairing.
The extremely stylish black board comes with five PCIe-x16 slots, of which two are connected to the chipset with a full 16 lanes while the other three are connected electrically by 8 or 4 data lines.
This allows the use of a 28 or 44 lane CPU as well as NVIDIA's 3-Way-SLI or AMD's 3-Way- CrossFireX configuration.

RAM:
8× DDR4 (Skylake-X: DDR4-2.666; up to 128 GB with a 44 or 28 lane CPU)
4× DDR4 (Kabylake-X: DDR4-2.666; up to 64 GB with a 16 lane CPU)
Quad-Channel (Skylake-X; supported by CPUs with 44 or 28 lanes)
Dual-Channel (Kaby Lake-X; supported by CPUs with 16 lanes)

Cytat:

Gigabyte deploys five full-length PCIe slots spread across a six-deep span.
The pair of ‘Dual Armor’ metal-reinforced slots are the primary slots that both receive up to 16 Gen 3 lanes from the CPU.
The bottom full-length slot is the other high-bandwidth link, receiving up to 8 lanes from a 44-lane chip.

PCIe lane distributions for slots 1, 3, and 5 are x16/x16/x8 for a 44-lane CPU, x16/x8/none for a 28-lane CPU, and x8/x4 when using a 16-lane CPU. That’s right – SLI is not supported with a 16-lane CPU, nor is a full x16 connection to a single GPU. Gigabyte should take plenty of the blame for this but, quite frankly, Kaby Lake-X chips are such stupid products on the X299 platform that it’s hard to throw too much criticism the board vendor’s way.
We checked to make sure that the lack of x16 or x8/x8 support was not a mistake in Gigabyte’s product information. It was not a mistake. This is a £270 motherboard that will not support SLI with a 16-lane CPU. That’s not good enough, irrelevant of whether the Kaby Lake-X CPUs should or should not exist.

The remaining slots are labelled PCIEX4_1 and PCIEX4_2. The upper four-lane slot (sat below the primary graphics card slot) looks to operate using CPU lanes when a 44- or 28-lane chip is installed. The lower four-lane slot (sat below the secondary steel-plated slot) looks to use four lanes from the chipset.

I would have thought that the latter would share its bandwidth with one of the M.2 connections as that would have been a logical compromise on a rarely-used PCIe expansion slot. However, Gigabyte does not make this clear anywhere in the manual and this will cause confusion for potential customers with heavy PCIe expansion requirements.
