Turbo Processing Unit (TPU) with Auto Tuning is able to automatically overclock the CPU to 95% of its potential maximum frequency, with an exhaustive stress-testing routine to ensure stable operation.2. Energy Processing Unit (EPU) automatically adjusts power consumption according to the PC's needs, going as far as shutting down unused extra I/O controllers and graphics cards' power levels when unused.3. Fan Xpert 3 is an advanced combination of hardware and software that can automatically calibrate PWM (on all 4-pin fan headers) or DC fans in the system for the right combination of cool and quiet. 4. Extreme Engine DIGI+ fully complies with Intel IMVP8 specifications to ensure stable digital power delivery to increase OC potential, enhance system stability and improve power efficiency.5. Turbo App allows for customized overclocking, cooling, network prioritization and audio profiles to be applied automatically on a by-application basis, making transitioning from gaming to watching a movie seamless.UNLOCK 10GBPS ETHERNET WITH THE 10G EXPRESSSupercharge the ROG MAXIMUS VIII EXTREME/ASSEMBLY with the enterprise-speed ROG 10G Express expansion card. Included with the ROG MAXIMUS VIII EXTREME/ASSEMBLY, the 10G Express, utilizes PCIe 2.0 x4 for next-gen LAN speeds of up to 10Gbps, up to 10x faster than today's fastest onboard consumer Ethernet!EXTREME ENGINE DIGI+The removal of the fully integrated voltage regulator (FIVR) on 6th Gen Core CPUs has once again brought digital power delivery to the forefront. DIGI+ NexFET MOSFETs, 10K Japanese-made black metallic capacitors (rated for 10,000 hours at 105° C) and Microfine Alloy Chokes deliver stable, reliable power for sustainable overclocking.FAN XPERT 3: DEDICATED WATER PUMP HEADERIn addition to all 4-pin headers supporting PWM & DC control, self-contained and custom water cooling systems now have a dedicated header to connect to that provides the required 1A of power for both DC- or PWM-controlled pumps without having to sacrifice a CPU fan header.ASUS PRO CLOCK TECHNOLOGYA dedicated base-clock (BCLK) generator designed for 6th-generation Intel processors that allows overclocked base clock frequencies up to or beyond 400MHz*, enabling additional flexibility in overclocking methods.FASTER STORAGE BY DESIGNThose looking to adopt speedy next-gen PCIe M.2 x4 or NVMe U.2 drives will find both solutions onboard, with the onboard M.2 supporting lengths of 2242, 2260, 2280 and 22110, ready for larger capacity M.2 drives. For those that must have the fastest speed at any cost, the MAXIMUS VIII EXTREME/ASSEMBLY supports RAID configurations.USB 3.1, TWO WAYSWith both Type A and Type C USB 3.1 ports onboard, the MAXIMUS VIII EXTREME/ASSEMBLY is capable of handling current USB 3.1 devices, as well as up-and-coming devices. What's more, ASUS USB 3.1 performance can take advantage of USB 3.1 Boost, pushing transfer speeds even higher than competitors' offerings.3X3 802.11AC WI-FIWi-Fi on the ROG MAXIMUS VIII EXTREME/ASSEMBLY is about far more than convenience. This is Wi-Fi that evokes envy from wired connections, with up to 1300 Mbps throughput in a 3T3R dual-band configuration. The included antenna features a magnetic base with swivel for optimal placement.INTEL ETHERNET FOR NO-LAG GAMINGDemand more from the wire with ROG networking. With Intel I219-V Gigabit LAN as the foundation, wired connections inherently enjoy higher throughput and lower CPU overhead compared to alternatives. On the software side, ROG GameFirst advanced packet prioritization software ensures your game gets the bandwidth it deserves to minimize ping times. And because the longevity of your ethernet port is perhaps the last thing you want to worry about, LANGuard hardware-level safeguards for both ESD and surge protection so you can focus on your game and worry only about K/D.REINVENTED SUPREMEFX 2015 AUDIOMore than an evolution, ROG SupremeFX 2015 is a revolution in integrated audio design, combining high-end audio components with expertly-engineered layout. From the ROG-pioneered isolated audio layout with red-line shielding designed to minimize interference to the renowned ESS ES9023P DAC with dedicated clock to eliminate jitter, SupremeFX 2015 ensures immersive gaming audio with impeccable clarity.INTRODUCING SUPREMEFX HI-FIBuilt with high quality premium Nichicon & WIMA capacitors and encorporating ESS' flagship 9018K2M SABRE DAC, ROG SupremeFX Hi-Fi USB DAC provides true to life audio reproduction in a neat, all-in-one solution exclusive to the ROG MAXIMUS VIII EXTREME/ASSEMBLY.LED LIGHTING TO CUSTOMIZE YOUR BUILDBuilding an ROG rig is as much about aesthetics as it is about performance. The ROG eye on the PCH of the ROG MAXIMUS VIII EXTREME/ASSEMBLY can be customized along the full RGB spectrum, enabling you to select your perfect color from 1.6 million available colors. The behavior of the lighting can be customized as well, with five different available effects.ROG RAMCACHEIt's no mystery that DRAM has the fastest transfer speed of any storage medium within the PC. With increasing memory densities, there is reason to ask more from RAM. ROG RAMCache intelligently caches files that are frequently accessed, minimizing load times, and automatically customizing to your behavior.ROG KEYBOT IIGoing beyond the functionality of even the most advanced gaming keyboards, KeyBot II upgrades your existing keyboard instantly.
