LGA1150 (Intel Core i3/i5/i7/Pentium/Celeron), Intel H81, 2 x DDR3 DIMM 1066/1333/1600 (up to 16GB), 2 x SATA 2, 2 x SATA 3, 1 x Parallel Port, 2 x PS/2, COM, HDMI, 2 x USB 2.0 / 3.0, LAN, ATX Bitcoin mining
Bitcoin is a digital currency that is recognized globally, and this motherboard is specifically designed for mining bitcoins. This robust mining machine is built with the best materials to help miners hit jack pot.

Secret #1
ASRock’s BTC motherboards are equipped with six PCI expansion slots, so that miners may install up to six graphics cards to mine simultaneously. Maximize your chances of getting bitcoins now!

Secret #2
Besides adequate PCI expansion slots, ASRock’s BTC motherboards also have two extra 4-pin power connectors for offering more power for your graphics cards. Never underestimate these two small power connectors that distinct ASRock’s BTC motherboards from other fake mining motherboards! They provide stable voltages and greatly reduce the risks of burning your motherboard or graphics cards.

Please MUST install TWO PSU’s 4-pin power cables to your MB’s TWO 4-pin power connectors. Plug the 4-pin power connector closest to the PSU (1) to the 4-pin power connector closer to the PCIe slots (A). Then plug the 4-pin power connector which is second closest to the PSU (2) to the other 4-pin power connector (B).

If your PSU only provides ONE, then please MUST install it to the 4-pin power connector closer to the PCIe slots.

Important: Make sure both the connected 4-pin and 24-pin power connectors are on the same PSU; otherwise, the motherboard may be damaged.

High Density Glass Fabric PCB
What you’ve never understood about your computer is that it is scared to death of water, H2O, humidity or whatever you’d like to name it. And even though you do not see the water, actually there may be lots of excessive moist in the air killing your motherboard silently and slowly. No, your motherboard doesn’t melt when in contact with water like the wicked witch of the west, but it dies of short circuit. Luckily, ASRock has a new High Density Glass Fabric PCB design that reduces the gaps between the PCB layers to protect the motherboard against electrical shorts caused by humidity.

4 Power Phase Design
Compared to other competitors’ 3 Power Phase design on the motherboards, ASRock adds a finishing touch by implementing 4 Power Phase design and sturdy components for delivering smoother power to the CPU, thus enhancing the motherboard’s performance and stability at lower temperatures.

Dehumidifier
Dampness kills most electronics, so it's a better idea to keep your personal computer dry. Now users may prevent motherboard damages due to dampness by enabling Dehumidifier. When it is enabled, the computer will power on automatically to dehumidify the system after entering S4/S5 state.

Easy Driver Installer
For users that don’t have an optical disk drive to install the drivers from our support CD, Easy Driver Installer is a handy tool in the UEFI that installs the LAN driver to your system via an USB storage device, then downloads and installs the other required drivers automatically through the internet.

Fast Boot is so fast that it is impossible for users to enter the UEFI setup utility during POST. Therefore, ASRock Restart to UEFI technology allows users to easily enter the UEFI setup utility automatically when turning on the PC next time. It is designed for those who constantly need to enter the UEFI setup utility.

HDMI™ (High-Definition Multimedia Interface)
This motherboard supports HDMI™ (High-Definition Multimedia Interface) which is an interface standard for transferring uncompressed video data and delivering multi-channel audio through a single cable. Both video and audio data signals transferred through the HDMI™ interface are digital without being converted into analog, therefore it delivers the richest pictures and the most realistic sounds.
