For the Z370 chipset, ASRock states they have an improved power phase design with “more power phases than ever” said to provide “unmatched overclocking capabilities, lower temperatures, and system stability”. ASRock boards also use their 'Hyper DDR4' nomenclature for improved memory performance, which according to their blurb indicates that the traces are optimized and memory circuitry isolated, providing pure clean memory signals 'for compatibility, stability, and performance' - also known as a revision of T-Topology. This allows some boards in the lineup to support speeds up to DDR4-4333. ASRock is one of the board partners offering 10 Gbps Ethernet via an onboard Aquantia controller port on the flagship Z370 Professional Gaming board. This is where we start.

ASRock Z370 Professional Gaming i7

The Fatal1ty Z370 Professional Gaming i7 looks like a high-end motherboard, with an extended shroud covering the rear panel and audio section, dual VRM heatsinks connected via a heatpipe, a trio of M.2 slots, and all full-length PCIe slots are strengthened in order to better support heavier video cards. There is some artwork on the board where the M.2 slots are located; otherwise, it is an all jet black with RGB LEDs peeking out through the shrouds and the bottom of the PCH heatsink. A debug LED and power/reset buttons are also found just below the chipset heatsink at the bottom of the board. Additional RGB LEDs can be added via the single RGB LED header.

A maximum of 64GB of memory through the four slots, with a supported speed up to DDR4-4333+. The DDR4-4333 rated speeds are the fastest listed from any manufacturer so far. The Pro Gaming i7 has a total of five PCIe slots: three full-length and two x1. All three full-length slots are reinforced, and work in x16 single, dual at x8, and all three at x8/x4/x4 modes. This lane configuration allows support for 2-way SLI and 3-way Crossfire. The x1 slots are ‘flexible’ in that the slot is open-ended, and larger cards are able to fit the slots if they only need x1 bandwidth.

Most Z370 motherboards have six SATA ports, while the Z370 Gaming i7 has eight. The other two ports are driven by an ASM1061 chipset which takes one PCIe from the chipset to provide two SATA ports. The board comes equipped with three M.2 slots, with two able to fit 110mm modules and the other supports 80mm drives. There is some lane sharing going on here, as the M2_1, SATA3_0 and SATA3_1 ports share lanes, as do the M2_2, SATA3_4, and SATA 3_5.

Audio duties are handled by a Realtek ALC1220 audio codec, which uses Nichicon Gold series audio caps as well as a NE5532 headset amplifier for the front panel (supports up to 600Ω headphones). Networking functionality can be handled by any of the four network solutions on the board: there are two Intel Gigabit LANs (an I219-V and I211-AT), and then there is the monster at the end in the Aquantia AQC107 controller supporting 10 Gbps for use with high bandwidth applications. Wireless networking is also included via the use of an Intel 802.11ac Wi-Fi module. It supports Bluetooth 4.2, is dual band, and allows wireless connection speeds up to 433Mbps, which suggests it is the AC3165.

There are three USB 3.1 (10 Gbps) ports in total, with two on the back panel (Type-A and Type-C) with the third Type-C an internal header for the front panel. There are four more USB 3.1 (5 Gbps) ports on the back panel with another two internal headers driven by an ASM1974 hub. Last, the Gaming i7 uses three USB 2.0 headers to support another six ports. The remainder of the back panel includes a clear CMOS button, a legacy PS/2 port, HDMI and DisplayPort video outputs, and audio jacks with SPDIF.

    The Asus Strix Z370-G mATX may be up on Amazon's website, but it has been Out of Stock ever since the page went up with no shipping date in sight. NewEgg Canada has it out of stock and NewEgg's US website doesn't even have a page for it. To call it available is inaccurate. Reply

    Well, I am typing this on Asus Strix Z370 I + i5 8400 PC so not entirely vaporware. People may be whining but it seems that Intel can't keep up with the demand... Reply

    got an 8600k today at Newegg. They still have stock after 4 hours so it looks like they may be starting to get large shipments. I7 is still out of stock though Reply

    Amazon is different than newegg, if it says Out of Stock, if you order it it will ship when it comes in stock. Sometimes it will be same day even or next day. Amazon will only show "This item is not available" if completely out of stock for foreseeable future. They do this because it stops items from completely selling out right away so supply can be steady. Reply

    I have found that Asus treats USA customers like a red headed step child. They will send units to the UK, australia, and all of Europe before they will send 1 single board to the USA.

    Some advice: Start looking at Overclockers.UK and have it imported to the USA.. The $30 DHL International shipping is faster than USPS Priority Mail or UPS International Express Saver. No VAT tax either.

    This is what i had to do to get a Rampage VI Extreme. Newegg hasn't gotten a R6E in stock for 2 months after the initial release batch.

    Does Asus USA cover warranty issues then since you bought it from UK? Reply

    Yeah I've been waiting on the Asus z370-g. I can't find an i7-8700k right now either so it's all right. Hopefully I'll be able to get both before Christmas (along with the rest of the upgrade). Reply

    This is so great. I find it increasingly difficult to find the right mainboard and this type of posting consolidates a lot of research time. Reply
  • SanX - Sunday, October 22, 2017 - link

    There are no "right" mobo here. Right future proof and super fast mobo has to be a dual-processor at least. Dual-SLI for example offers benefits for speed but in many cases the dual-chip is doing the same in simulations. Reply
