Thus, its able to support the latest DDR4 memory modules with most extreme memory performance! Super Alloy Motherboard XXL Aluminum Alloy Heatsink Extra large aluminum alloy heat sinks that effectively take away heat from the MOSFET and chipset so that your whole system may perform more stable. Premium 60A Power Choke Compared to traditional chokes, ASRock’s premium 60A power chokes effectively make the saturation current up to three times better, thus providing enhanced and improved Vcore voltage to the motherboard. Premium Memory Alloy Choke Specifically designed for memory power delivery, these new alloy chokes feature a highly magnetic and heat resistant design, thus delivering more stable and reliable power to the motherboard and memory modules. Nichicon 12K Black Caps Supreme 12K black capacitors with lifespans of at least 12,000 hours. Compared to other counterparts on high-end motherboards that merely have lifespans of around 10,000 hours, ASRock applied Nichicon 12K Black Caps that offer 20 longer lifespans and provide more stability and reliability. I/O Armor A new designed protective cover for all of the crucial parts near the motherboards rear I/O, so that they wont easily be damaged by static electricity. Matte Black PCB A new mysterious matte black and copper color scheme to match the prestigious components on ASRocks high-end motherboards. High Density Glass Fabric PCB High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity. BIOS Flashback Get the most convenient BIOS flashing with just a simple click. Users can easily achieve the latest BIOS support with a USB and power supply, No CPU, RAM or other components required. U.2 Connector U.2 is for connecting some of the world’s fastest U.2 PCIe Gen3 x4 SSDs. Hyper BCLK Engine III An additional external base clock generator that supports PCIe frequency overclocking. It provides a wider range of frequencies and more precise clock waveforms, allowing any user to get most from their CPU investment with precise, stable overclocking. Purity Sound 4 Its time to enjoy the most purified audio performance with ultra high definition. Purity Sound4 is a combination of several hardware, software audio solutions. 7.1 CH HD audio with the latest Realtek ALC1220 audio codec, individual PCB layers for R/L audio channel, 120dB SNR DAC and other technologies to deliver the crispest sound effects. PCI-E STEEL SLOTS The advanced PCI-E Steel Slots packed with solid cover that prevent any signal interference with graphics cards. It also ensures the heavy graphics cards to be well-installed in the PCI-E slots safely.
