ASRock X399 Phantom Gaming 6

Visual Walk Around

The X399 Phantom Gaming 6 represents one of ASRocks two Threadripper based boards, their Fatal1ty X399 Professional Gaming holds the top-end segment while we settle with our value focussed offering today. The colour scheme of the X399 Phantom Gaming 6 aligns with the rest of the Phantom range. The black and red will fit a variety of builds and includes RGB LEDs to the chipset heatsink. Additionally, there are two headers for RGB and ARGB that can be used with either ASRocks own Polychrome utility or many of the other mainstream applications.
To the top we have our dual 8 pin 12V ATX power connectors and eight DIMM slots flanking the CPU socket in a four and four configuration, supporting quad-channel memory up to 128GB of DDR4 3400. Moving around the board we have ample cooling options with a total of 5 fan headers that include a CPU and AIO connections that can be assigned via the BIOS.

Power is supplied via a 6+2 phase delivery limiting the board to 180W TDP processors. However, when we come to testing later we have actually used a 2990WX, AMD’s flagship 250W TDP chip. When we spoke with ASRock regarding our concerns, the board can actually run this silicon but we have not overclocked it to ensure we don’t fry the motherboard. So for those out there with a higher-end chip, yes, it is possible at least but we would not recommend it. AMD was originally to send over a 1950X for this build and review, none were available and we couldn’t turn down their offer of a 2990WX instead.

For PCIe, ASRock has provided their Steel Armour to all three slots while for storage, M.2 can support a 22110 and two 2280 drives. One M.2 slot also includes a heat sink for those chasing temperatures of storage devices. Audio is taken care of by a Realtek ALC1220 HD audio codec and is separated in the usual fashion we have all become accustomed to. A nice touch is the right-angled audio connector that we wish all manufacturers would implement as standard for motherboards across all connectors including USB and ATX 24 pin.
