Dark hues predominate on this motherboard, drawing attention to premium metal textures, nickel-plated surfaces, elegant contours and a stereoscopic visual effect on the large M.2 and chipset heatsink. This board also features Polymo Lighting II. This enhanced lighting module, integrated into the I/O housing, provides more dynamic RGB illumination for the ROG logo. AI COOLING II An ASUS-patented algorithm reduces unnecessary noise while performing a quick stress test, then monitors CPU temperatures to dynamically adjust fans to optimal speeds. AI OVERCLOCKING ASUS AI Overclocking profiles the CPU and cooling system to determine the optimal system configuration. Predicted values can be automatically engaged or used as a baseline for further experimentation. AI NETWORKING II Fast Check Armoury Crate's Fast Check allows users to quickly detect WiFi signal strength. Traffic Monitor Armoury Crate Traffic Monitor tracks the usage of your current WiFi channel. Switch to a less congested channel by clicking the Channel Switch button* to improve network performance. *The Channel Switch feature requires pairing with an ASUS router. If not paired with an ASUS router, the channel switching process can be done in the Router IP section of the Traffic Monitor. Gamefirst GameFirst is now integrated with Armoury Crate for an even better user experience. GameFirst optimizes network performance by allocating bandwidth in real-time, based on intelligent algorithms designed for various customizable usage scenarios and corresponding learning algorithms. The latest update includes dedicated support for NVIDIA GeForce NOW to ensure the lowest possible latency during intense cloud gaming streaming sessions. To improve the user experience, GameFirst is now integrated with Armoury Crate. Direction Finder Armoury Crates Direction Finder* helps users detect the optimal antenna orientation for the best WiFi signal strength. *Direction Finder is only compatible with connections in the 5GHz and 6GHz bands. OVERCLOCKING CORE FLEX In its simplest form, you can maximize the base clock during light loads and set breakpoints to gradually reduce the CPU core frequency as temperature or current increases. However, the system is extremely adaptable, supporting multiple user-controlled functions that can manipulate power, current, and temperature limits independently. This allows you to tailor CPU performance to your will. Dynamic OC Switch Dynamic OC Switcher maximizes CPU performance by allowing you to set current and temperature thresholds to automatically switch between manual overlock for heavy

Model overview based on user reviews  
The Asus ROG CROSSHAIR X870E HERO motherboard is positioned as a high-end gaming option with overclocking capabilities, but user reviews suggest it may not justify its premium price. One of its standout features is the ability to connect up to 5 M.2 drives, though this comes with significant trade-offs, such as reduced bandwidth for the graphics card when all slots are used. Users have reported difficulties with the installation and removal of M.2 drives, especially when using certain cooling systems like the Arctic Liquid Freezer, which obstructs access. Frequent issues with M.2 slot recognition have been noted, even after BIOS updates, leading to frustration. Additionally, the absence of a PC speaker complicates monitoring boot processes. While the motherboard offers a robust set of features, including support for Wi-Fi 7 and multiple USB connections, the lack of driver support for some features on Windows 10 and the overall performance issues have left users disappointed. For those seeking better value, alternatives like the Threadripper or other motherboards with fewer M.2 slots might be more appealing.

Expensive but high quality
21 December 2025 
Expensive, but I don't regret the purchase, it feels like a reliable product, and in six months, no significant issues have arisen.
Digital temperature indicator, cool design, well thought out quality
Takes a long time to start

Choose either a simpler option or consider looking towards a Threadripper.
22 February 2025 
Yesterday, BIOS update 1104 was released, which fixes the loss of M2 in the second and third slots during auto-detect of connected devices if the bandwidth mode for PCI-ex is set to Auto. In any case, if you enable x16 for the graphics card to achieve full bandwidth, it's impossible to connect more than three M2 SSDs! Alternatively, you'll get half the bandwidth for the graphics card (x8 instead of x16) if you need to connect 4-5 M2s. This is an expensive high-end choice, where you have to choose between a graphics card or storage. This motherboard isn't worth the money – you might as well switch to Threadripper, which won't cost much more and offers many more benefits. Or choose any cheaper alternative with three M2 slots if you don't need more.
Nothing outstanding compared to cheaper motherboards
The only actual advantage that sets this motherboard apart from others is the ability to connect 5 M2, which is the Achilles' heel of this motherboard. Either x16 on the video and 3xM2, or 5xM2, but x8 on the video.
The Arctic Liquid Freezer CLC heavily obstructs M2_1.
Quick removal/connection of any M2 on an installed motherboard in the case with a discrete card installed is impossible - requires disassembly of the video card, disassembly of the mount for long video cards, disassembly of the CLC if changing M2_1 (not relevant for the "install and forget" scenario).
No PC Speaker - it's impossible to know when the machine has started (re)booting if you're not nearby and not watching the monitor intently. Especially if a memory training session is running (e.g., new processor installed, BIOS updated, memory settings changed, etc.) and it's crucial "not to miss the moment when BIOS POST appears." With a large amount of memory or, for example, four modules at once, watching can take a long time.

Absolute disappointment
9 February 2025 
Wanted Taichi, didn't wait for it (was looking for it for a month and a half), got this one. The box and contents look decent, but that's it. I would have bought either Taichi or better Godlike, but I have doubts, maybe everyone does it now. Previously (many years ago) motherboards over $100 were considered high-end, now for $700+ you get trash.
It was an additional big disappointment that there are no drivers for WiFi 7 for Win10, as well as USB4, (yet) - but this is not about this particular motherboard, but in general.
No
Price for such quality
Arctic Liqued Freezer is very tight on the M2.1 radiator
It is impossible to quickly add/remove M2 - it requires a complete disassembly with dismantling the discrete video card, the bar that supports it (for long V/C) + removing the liquid cooling system if you need to change M2.1. Any addition/removal of any M2 requires disassembling the system.
Regularly loses M2 when starting. BIOS update does not help. There are already a lot of complaints about this problem on the Asus forum.
Samsung 990 Pro, even a single one installed in the first M2.1, does not give the declared 7Gb/s - at best 2-2.5 Gb/s and the more data, the more it sags.
