ASRock Z390 Extreme4

The ASRock Z390 Extreme4 hails from a long line Extreme4  branded boards which go as far back as Intel's Z77 chipset which was released back in 2012. Fast forward to now and the new Z390 Extreme4 has a semblance of the previous Z370 Extreme4 board but with some key differences. First of all the Z390 Extreme4 now includes an M.2 heatsink for the bottom slot and the rear panel cover has classier ASRock branding across it. The RGB LED lighting zones remain in the same places from the heatsinks and audio PCB cover and that's where the differences end; aside from specifications of course and the fact that this board has the newer Z390 chipset included. ASRock advertises a 12-phase power delivery and has included a pair of 12 V ATX CPU power inputs; an 8-pin and 4-pin. The board also has support for DDR4-4300 memory with up to 64 GB of capacity across four available RAM slots.

ASRock has kept the same PCIe slot layout as the Z370 Extreme4 with a total of three full-length PCIe 3.0 slots with the top two being treated to a coat of ASRocks Steel Slot protection; bandwidth wise they operate (from top to bottom) at x16, x8 and in x4. Also included are three PCIe 3.0 x1 slots and the board has support for up to two-way CrossFire and three-way SLI multi-graphics card configurations. The board has a total of four RAM slots with support for up to a maximum of 64 GB in total. Storage wise the Z390 Extreme4 has eight SATA ports with six coming from the chipset and another two from an ASMedia SATA controller with support for 0, 1, 5 and 10 RAID arrays. The two M.2 ports do feature support for both PCIe 3.0 x4 and SATA, but it's worth pointing out that these likely that these slots will share bandwidth with other ports.

On the rear panel is two USB 3.1 Gen2 with a Type-A and Type-C port included along with a further four USB 3.0 Type-A ports. In addition to a PS/2 combo port is a trio of video outputs consisting of a DisplayPort, HDMI and a D-Sub. The Z390 Extreme4 doesn't have any wireless networking capability but there is scope to purchase an E-key PCIe adapter and the rear panel includes a bracket for it. The single wired LAN port is powered by an Intel I219V Gigabit controller while the S/PDIF and five 3.5 mm audio jacks are impelled by a good quality Realtek ALC1220 HD audio codec.

Buy the ASRock Z390 Extreme4

The Extreme4 motherboards usually combine a good mixture of features, specifications and for the new iteration, the ASRock Z390 Extreme4 has a recommended launch price of $180 which is reasonable all things considered. The board has everything minus integrated Wi-Fi and is aimed more at enthusiasts than gamers; plenty of Phantom Gaming boards for those. There is the added wow factor of RGB built into the heatsinks and overall the design follows a much cleaner and neutral aesthetic than the new Phantom branded boards.

    Still no mention of any Z390 boards with native Thunderbolt 3 (not AIC)! Has Intel given up on Thunderbolt for the PC world?

    If it's not integrated into the chipset, it's not really native as such. The ASRock Z390 Phantom Gaming-ITX/ac has a Thunderbolt 3 port on the rear panel, but that's the only one I'm afraid

    Oculus Rift requires 3 USB3 ports and doesn't accept any of them being connected to a hub, they all need to be connected directly into a raw port. I had to buy a dedicated 3GIO USB 3 board that added 6 useful extra ports. In my (yes, old) Gigabyte z87 mobo I also had issues using keyboard and mouse on USB 3 ports inside UEFI and some recovery softwares, so I had to buy a USB 2 mirror to connect them.

    Because of that, having USB 2 ports on front panel and nice quantity of USB 3 is what most differs mobos for me, given that all other features are nearly the same.

    ASUS Z390-A seems to be the best option. It has the important double USB2 ports, 5 USB3 ports and still has HDMI and DP for emergencies.

    I wish MSI had released a "godlike" board for the Ryzen series.

    You list the ASRock Z390 Phantom Gaming-ITX/ac above as an ATX board, but it's actually mITX. FYI
  • gavbon - Friday, October 19, 2018 - link

    I have gone through every page where the Phantom Gaming-ITX/ac is listed, but I can't see where it says it's an ATX board? Could you please be more specific? Are you viewing on mobile or desktop?

    It would be really helpful to break out one more criteria into a table: Type-C header for case-front ports.

    Helping a friend put together an i5 system and, knowing he'll keep it for a long time, am trying to get even with peripheral connectors (already has a monitor, so no using that as a hub). It's relatively easy to identify cases with a Type-C port, but that's pointless without a motherboard header. Having to go into each board's page to check is time-consuming.

    6 months later and I'm here for EXACTLY this reason. I've gone through probably 50 manuals over the past few days squinting to find this information. What a pain.
  • Synomenon - Thursday, October 18, 2018 - link

    So on the ASRock Z390 Phantom Gaming-ITX/ac, is the TB3 port on the rear using up lanes from CPU (making the only 16x slot, 8x only)?

    If it's not using lanes from the CPU, how will using that TB3 port (say with a USB3.1 Gen2 hub OR TB3 hub) affect all the other ports / IO on the board?
  • repoman27 - Thursday, October 18, 2018 - link

    Going off of what TweakTown published, it's a single-port Intel JHL6240 "Alpine Ridge" controller with a PCI 3.0 x2 connection to the PCH. So it won't affect the PEG lanes from the CPU. I'm amazed it's not Titan Ridge at this point though.
