The ASUS X99-DELUXE is a top mid-range motherboard for the new Intel high-end “Haswell-E” processors, based on the new LGA2011-v3 socket. It includes five PCI Express 3.0 x16 slots, 12 SATA-600 ports (with two SATA Express connectors), 14 USB 3.0 ports, a high-end audio controller, and an integrated Wi-Fi 802.11ac interface. Let’s take a good look at this board.
The new Intel X99 platform supports the new socket LGA2011-v3 processors. However, it is not compatible with former socket LGA2011 CPUs, which require motherboards based on the Intel X79 chipset. The main difference between the two platforms is that LGA2011 processors are compatible with DDR3 memories, while LGA2011-v3 CPUs can use the new DDR4 standard.
The main differences between the X99 and the X79 chipsets, besides the CPU support as mentioned above, are the number of USB 3.0 and SATA-600 ports: the X99 offers ten SATA-600 and six USB 3.0 ports, while the X79 supports only two SATA-600 ports and has no native support for USB 3.0 ports.
In Figure 1, you see the ASUS X99-DELUXE motherboard. What immediately catches the eye is its white plastic frame that covers the audio section and the rear panel connectors. There are details in white on the heatsinks too, which gives the motherboard an unique and clean look. It uses the ATX form factor (12 x 9.6 inches or 305 x 244 mm).
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 ASUS X99-DELUXE comes with five PCI Express 3.0 x16 slots. With a 40-lane processor installed, the board supports x16/x0/x16/x0/x0, x16/x0/x16/x0/x8, x8/x8/x16/x0/x8, or x8/x8/x8/x8/x8 configurations. With a 28-lane CPU, the board supports x16/x0/x0/x0/x0, x16/x0/x8/x0/x0, or x8/x8/x0/x8/x0 configurations. With a 28-lane processor, two of the PCI Express 3.0 x16 slots work as PCI Express 2.0 x1.
The motherboard supports three-way SLI arrays, and CrossFireX with up to four video cards.
When installing dual-slot video cards, you “kill” the slot immediately to the left (looking at the motherboard with its rear connectors facing up) of the slot being used. Therefore, if you install a dual-slot video card in the second, third, or fourth PCI Express x16 slot, you will be unable to use the slot to its immediate left.
There is also a PCI Express 2.0 x4 slot, which shares bandwidth with one of the SATA Express connectors, so the SATA Express port will be disabled when this slot is in use.
THe X99-DELUXE comes with two M.2 slots. One of them uses a vertical stand, shown in Figure 4. However, this slot supports only PCI Express M.2 cards, being not compatible with SATA M.2 modules. This slot shares bandwidth with the fifth PCI Express x16 slot. The other M.2 slot is available as a PCI Express x4 add-on card, also not supporting SATA devices.
[nextpage title=”Memory Support”]
Intel socket LGA2011-v3 CPUs have an embedded memory controller, meaning that it is the processor, not the chipset, which defines what memory technologies you can have and the maximum amount of memory that is possible. The motherboard, however, may have a limitation as to how much memory can be installed.
The integrated memory controller from socket LGA2011-v3 processors officially supports DDR4 memories up to 2,133 MHz. According to ASUS, the X99-DELUXE supports memories up to 3,200 MHz.
One of the most important features of the socket LGA2011-v3 processors is the support for the quad-channel memory architecture, which allows the memory to be accessed in 256-bit mode for higher performance. Since each memory module is a 64-bit entity, four memory modules are needed to enable this architecture. If only two or three memory modules are installed, the memory will be accessed under dual- or triple-channel architecture, respectively.
The ASUS X99-DELUXE has eight memory sockets (four at each side of the CPU socket) and, since DDR4 memory modules can be found in capacities up to 8 GiB, you can have up to 64 GiB with this motherboard if you use eight 8 GiB modules.
In order to enable the quad-channel mode, you must install four or eight identical memory modules. When installing four memory modules, you will have to “skip” one memory socket, filling only the dark gray sockets (you will have to pay a little attention to the sockets, since the dark gray and black sockets are very close in color.)

The Intel X99 chipset is a single-chip solution, which is also known as a PCH (Platform Controller Hub). This chip supports ten SATA-600 ports (there are no SATA-300 ports), supporting RAID (0, 1, 10, and 5).
The ASUS X99-DELUXE offers those ten SATA-600 ports (two of them are shared with a SATA Express connector), plus one SATA Express port (that can be used as two individual SATA-600 ports) controlled by an ASMedia ASM106SE chip. All SATA ports are located at the motherboard’s edge and rotated 90 degrees, so that video cards will not block them. ASUS could have used different colors for the SATA Express port controlled by the auxiliary chip.
The Intel X99 chipset supports eight USB 2.0 ports and six USB 3.0 ports. The ASUS X99-DELUXE offers six USB 2.0 ports, two soldered on the rear panel and four available through two headers located on the motherboard. It also supports 14 USB 3.0 ports, ten soldered on the motherboard rear panel (all of the controlled by two ASMedia ASM1074 and one ASMedia ASM1042 chips) and four available through two headers on the motherboard, controlled by the chipset.
The ASUS X99-DELUXE does not support FireWire or Thurnderbolt ports.
This motherboard supports 7.1+2 audio format, i.e., eight channels plus two independent channels for audio streaming. On this motherboard, the audio is generated by the chipset using the Realtek ALC1150 codec, which is an excellent audio codec, providing 115 dB signal-to-noise ratio for the analog outputs, 104 dB signal-to-noise ratio for the analog inputs, and up to 192 kHz sampling rate for both inputs and outputs, with 24-bit resolution. These specifications are good even for the user who wants to work professionally capturing and editing analog audio (e.g., converting LPs to CDs or MP3, converting VHS to DVDs or any other digital format, etc.).
The analog audio outputs are independent and the motherboard also comes with an on-board optical SPDIF output. It also has a header labeled “SPDIF_OUT”, where you can install an adapter to have a coaxial SPDIF output or to connect a cable to older video cards that required a physical connection to have audio on their HDMI outputs.
The analog audio outputs are independent only if you use a 5.1 analog speaker set. If you install a 7.1 analog speaker set, you will need to use the “line in” jack.
The portrayed motherboard has two Gigabit Ethernet ports, one controlled by an Intel i218V chip and one controlled by an Intel i211-AT chip, supporting teaming (ability to combine the two ports to behave as a single 2 Gbps connection, if you use compartible hardware in your network).
The X99-DELUXE has an integrated dual-band 802.11 a/b/g/n/ac Wi-Fi interface. It comes with a dual-band MIMO 3×3:3 antenna set. The board also supports Bluetooth 4.0.
This motherboard comes with a button in the rear panel named “BIOS Flashback” that allows the user to update the BIOS even with no installed CPU and memory. Just insert a flash drive containing the BIOS file in an USB port, press the button for three seconds, and the BIOS will be flashed.
In Figure 7, you can see the motherboard rear panel, with the “BIOS Flashback” button, ten USB 3.0 ports, two Gigabit Ethernet ports, two USB 2.0 ports, three Wi-Fi antenna connectors, one optical SPDIF output, and the analog audio jacks.
[nextpage title=”Other Features”]
The portrayed motherboard supports the installation of a TPM (Trusted Platform Module), in charge of storing encryption keys in order to increase the security of the computer.
This X99-DELUXE has a POST diagnostics display that shows through a two-digit code which component is preventing the computer from turning on. It also has power, reset, and clear CMOS buttons, as shown in Figure 8.
There is a “TPU switch” that enables an automatic overclocking, increasing the CPU clock multiplier (position “I”) or both the CPU clock multiplier and the CPU base clock (position “II”), and an “EPU switch” that enables or disables a power-saving feature. There are also one switch that configures the SLI or CrossFireX mode, and an EZ_XMP switch, which increases memory clock.
There is also a “MemOK!” button, which allows you to test the compatibility of the memory modules that are installed.
Figure 9 shows some of the accessories that come with the motherboard. Notice the M.2 card, which allows you to install an M.2 PCI Express x4 module in a PCI Express x4 slot (not compatible with SATA M.2 modules), and a fan extension card, which allows the motherboard to control four additional four-pin fans.
In Figure 10, you can see the other accessories that come with the ASUS X99-DELUXE.
[nextpage title=”Voltage Regulator”]
The CPU voltage regulator circuit of the ASUS X99-DELUXE has eight phases for the CPU. The voltage regulator is controlled by an ASUS DIGI+ ASP1257 chip, using a digital design. Each phase is controlled by one IR3550M integrated circuit.
The ASUS X99-DELUXE uses solid electrolytic capacitors with a 5,000-hour life-span, twice the amount presented by regular solid capacitors. All coils on this motherboard are ferrite-core models, which can provide up to 20% improvement in efficiency.

* Researched at Newegg.com on the day we published this review.
The ASUS X99-DELUXE is a good motherboard for socket LGA2011-v3 systems. It only lacks a high-end PCI Express x16 slot configuration, with a PLX chip to automatically switch bandwidth to the slots that are requiring it; but this feature is only needed if you plan to build a very high-end gaming system with more than three video cards in SLI or CrossFireX configuration, which is not common.
The storage configuration is excellent, with 12 SATA-600 ports and two SATA Express connectors, which is more than enough even for the hardcore user or server applications. And the rear panel with ten USB 3.0 ports is impressive.
The highlights of this motherboard are the audio section, which uses a high-end codec with an outstanding signal/noise ratio, and the presence of a high-end Wi-Fi interface, based on the IEEE 802.11ac standard, with three antennas.
The only drawback we see with this motherboard is the lack of an M.2 slot compatible with SATA modules, since both M.2 slots offered (one on the motherboard and one on an add-on PCI Express card) are only compatible with PCI Express M.2 modules.
