The ASUS ROG Crosshair VIII Impact: A Sharp $430 Impulse on X570
by Gavin Bonshor on October 25, 2019 11:30 AM ESTBoard Features
The ASUS ROG Crosshair VIII Impact is one of two small form factor motherboards from ASUS and is the bigger of the pair with its slightly larger than normal PCB. Using the mini-DTX form factor allows ASUS to feature its ROG SO-DIMM.2 slot which allows users to install two PCIe 4.0 x4 M.2 drives with cooling support provided by the inclusive heatsink. Other storage options include four SATA ports with support for RAID 0, 1, and 10 arrays. The Impact features an Intel I211-AT Gigabit ethernet controller and an Intel AX200 Wi-Fi 6 802.11ax wireless interface; this also offers users BT 5.0 connectivity. Onboard audio is handled by ASUS's familiar SupremeFX S1220 HD audio codec and also includes an ESS ES9023P DAC. This adds three 3.5 mm audio jacks which are illuminated, as well as a single S/PDIF optical output on the rear panel. The implementation of the onboard audio is interesting as it's on an add-on card which is plugged into the PCIe 4.0 M.2 slot just beneath the full-length PCIe 4.0 x16 slot.

Test Bed
As per our testing policy, we take a high-end CPU suitable for the motherboard that was released during the socket’s initial launch and equip the system with a suitable amount of memory running at the processor maximum supported frequency. This is also typically run at JEDEC subtimings where possible. It is noted that some users are not keen on this policy, stating that sometimes the maximum supported frequency is quite low, or faster memory is available at a similar price, or that the JEDEC speeds can be prohibitive for performance. While these comments make sense, ultimately very few users apply memory profiles (either XMP or other) as they require interaction with the BIOS, and most users will fall back on JEDEC supported speeds - this includes home users as well as industry who might want to shave off a cent or two from the cost or stay within the margins set by the manufacturer. Where possible, we will extend out testing to include faster memory modules either at the same time as the review or a later date.

Readers of our motherboard review section will have noted the trend in modern motherboards to implement a form of MultiCore Enhancement / Acceleration / Turbo (read our report here) on their motherboards. This does several things, including better benchmark results at stock settings (not entirely needed if overclocking is an end-user goal) at the expense of heat and temperature. It also gives, in essence, an automatic overclock which may be against what the user wants. Our testing methodology is ‘out-of-the-box’, with the latest public BIOS installed and XMP enabled, and thus subject to the whims of this feature. It is ultimately up to the motherboard manufacturer to take this risk – and manufacturers taking risks in the setup is something they do on every product (think C-state settings, USB priority, DPC Latency / monitoring priority, overriding memory sub-timings at JEDEC). Processor speed change is part of that risk, and ultimately if no overclocking is planned, some motherboards will affect how fast that shiny new processor goes and can be an important factor in the system build.

New Test Suite: Spectre and Meltdown Hardened
Since the start of our Z390 reviews, we are using an updated OS, updated drivers, and updated software. This is in line with our CPU testing updates, which includes Spectre and Meltdown patches. We are also running the testbed with the new Windows 10 1903 update for AMD's Ryzen 3000 series CPUs, and X570 motherboard reviews. The Windows 1903 update improves multi-core and multi-thread performance on AMD's Ryzen processors with topology awareness meaning previous issues in regards to latency have been known to affect performance. As users are recommended to keep their Windows 10 operating system updates, our performance data is reflected with the 1903 update.

It's the same people complaining on every article about the same issue, despite the fact that they've been told time and time again that these fans run at low RPM or off completely when you are not pushing the IO heavily. For most people, they are inaudible 100% of the time. These people want to spin their narrative, not try to understand what people are telling themHardwareDufus - Friday, October 25, 2019 - link
I won't say that I'm disappointed. I like Zen2.... but I will do just one more cycle of waiting.... I want to see the Zen3 successor to the Ryzen 9-3950X... and the RDNA 2 successor to the Radeon RX 5700 XT. That's all probably 12-15 months away, but that's just about right. I too am on an I7-3770k (longest lasting CPU I have ever had as well). This will be the last machine I build of my professional working career (If I've gotten 7+ years out of my I7-3770k, I'm sure I'll get 5 years out of the Zen3 16core CPU).hmmm, my trusty SilverStone SG055BB is mini-ITX / mini-DTX compatible (I own two of them). However, I'd pay a max of $300usd for a board like this (even though admittedly it's just about the perfect board... optical audio out, wifi and 2 M2 slots for storage... I ALWAYS have two harddrives).
We will see if a successor to this board is available in 12-15 months when I make the Ryzen Zen3 & Radeon RDNA-2 jump.
I'll be fine if only PCI4 is supported at that point.... I won't hold off for PCI5 to be implemented.
Will be interesting to see if we start seeing 4TB M.2 storage devices at that point as well... and if 32GB Dimms at good speed will be more affordable. Yeah.. Looking at 16 Cores @ 4Ghz+, 2X32GB for 64GB of Ram, 2X4TB for 8TB of storage to drive 2 32" 4K monitors. Will be a nice rig for the sunset years of my IT career...

honestly I do not understand folks who say this you have a CPU that is in modern terms slow and a system thats the same AMD comes along with a really disruptive product that is leagues ahead of what you have and in its third generation yet still you want to wait !What the heck exactly do they need to do to get your buy in, if AMD didnt exist or bring Zen to the party intel would happily keep chugging out its same CPUs for the next 10 years, support the company thats brought the fight to them!

Well, I will build the new system with cash on hand... So I may have misrepresented why I will sit out...... It's just that in my budget at end of 2020/2021 will make room for my computer. By then it will be Ryzen Zen 3 Radeon RDNA-2 and I will be curious to see what they offer... That's all. If their release is stalled significantly... then I 12 months from now I will buy current gen Ryzen Zen 2 Radeon RDNA....and would be equally delighted to do so...HardwareDufus - Sunday, October 27, 2019 - link
But perhaps in that time.... we will see a X570 variant that won't require a fan.... again, won't be a show stopper, as the CPU and Video cards will have fans aplenty anyway.....evernessince - Saturday, October 26, 2019 - link
And yet all X570 motherboards either turn off the fan during low load or run at low RPM, making then inaudible.PeachNCream - Sunday, October 27, 2019 - link
Noise isn't the concern. Fan failure is what bothers the OP as indicated by noting fans are a regression in the movement toward fewer moving parts (which can suffer from mechanical failure). While noise might be a concern, broken little fans that are a PIA to replace are what have peoples' panties in a twist right now and we haven't seen any X570 motherboards operating long enough to get a good understanding of whether or not fan failures are going to be a problem or if, as you implied, they are generally not running to begin with (which begs the question why the motherboard manufacturers are adding them in the first place instead of using a more effective passive heatsink).Oliseo - Sunday, October 27, 2019 - link
But you're not interested in anything but laptops, I don't get why you're arguing with people about something you no longer care about.Just like arguing I suppose.
RavenRampkin - Sunday, October 27, 2019 - link
May I kindly take Peach's initiative? xDNot interested in laptops. Have one, it's fine. The current pricing situation is meh. 6/12 ultrabook and 8/16 laptop parts are crazy expensive. Graphics are expensive (Turing), boring (Turing GTX) or both (Radeon, sadly. Power hogs or underperformers, or both). Zen is a skillful fighter for new users but nothing of particular interest over a good ol' 4700MQ (minus the Vega... got a dGPU anyway)...
As for the fans, sorry bud. If the interested customer has to find ways in which a hackjob (just sry, this IS a hackjob... it's not 2005 anymore) doesn't svck (oh the fans are low RPM, oh they're not that short-lived, oh there's passive mode at 0.1% load) and is actually *not that bad*, then it's not really a good hackjob. The need for this dayum fan in the first place screams a littley oopsie from ASMedia, or a design less efficient than usual on AMD's side. OK higher demands than for 300 and 400 series, then why does Shintel get away without le fans? (Pls correct if wrong.) Also, you can still do it passive, funnily enough. Why should it be a blessing and not a default option?
Case in point right above (or below?) me. Adaptation 100. Spare me some lube guys, been shilling for AyyMD, AsRock, Powercolor and Seasonic long enough :P want to try out some other companies
TL;DR there's no advantage nor purpose in reinventing the sleeve bearing (or dual ball, depends) wheel.

PCI express 4.0 has significantly higher power requirements and thus heat output. X570 chipset is a repurposed Matisse IOD. Why you people complain about the chipset fan is beyond me, always gotta complain about something I guess. It's completely bloody inaudible on my X570M pro 4, and also completely unnecessary for all but the most intense I/o on both gen4 m.2 and the GPU.Stop complaining.
