Central Processing Unit (CPU) The motherboard comes with a surface mount LGA1150 socket designed for the Intel® 4th Generation Core™ i7 / Core™ i5 / Core™ i3, Pentium / Celeron ® ® processors. EMB-H81B CPU socket LGA1150 IMPORTANT: Unplug all power cables before installing the CPU. CAUTION! • Upon purchase of the motherboard, ensure that the PnP cap is on the socket and the socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket contacts/motherboard components. The manufacturer will shoulder the cost of repair only if the damage is shipment/transit-related. • Keep the cap after installing the motherboard. The manufacturer will process Return Merchandise Authorization (RMA) requests only if the motherboard comes with the cap on the LGA1150 socket.
2.4.1 Installing the CPU CAUTION! LGA1156 CPU is not compatible with the LGA1150 socket. DO NOT install an LGA1156 CPU on the LGA1150 socket. Chapter 2: Motherboard information...

System memory This motherboard comes with two Double Data Rate 3 (DDR3) Small Outline Dual Inline Memory Module (SO-DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are developed for better performance with less power consumption. The figure below illustrates the location of the DDR3 SO-DIMM sockets: DIMM_A1 DIMM_B1 Channel Sockets Channel A SO-DIMM_A1 EMB-H81B 204-pin DDR3 SO-DIMM sockets Channel B SO-DIMM_B1 Chapter 2: Motherboard information 2-11...
Clear RTC RAM (CLRTC) This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords. EMB-H81B Clear RTC RAM To erase the RTC RAM: Turn OFF the computer and unplug the power cord. 2. Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep the cap on pins 2-3 for about 5~10 seconds, then move the cap back to pins 1-2. Plug the power cord and turn ON the computer. 4. Hold down the <Del> key during the boot process and enter BIOS setup to reenter data.

20. Serial ATA 3Gb/s connectors (7-pin SATA3G_1) This connector connects to a Serial ATA 3Gb/s hard disk drive or an optical drive via a Serial ATA 3Gb/s signal cable. EMB-H81B SATA 3.0Gb/s connector NOTE: You must install Windows XP Service Pack 3 or later version before ® using Serial ATA hard disk drives. Power Supply Considerations CAUTION! • The external DC jack (5.5/2.5mm) is the primary power input connector of EMB-H81B. However, the desktop board also provides an internal 2 x 2 power connector that can be used in custom-developed systems that have an internal power supply. • There is no isolation circuitry between the external DC jack and the internal 2 x 2 power connector. It is the system integrator’s responsibility to ensure no more than one power supply unit is or can be attached to the board at any time and to ensure the external DC jack is covered if the internal 2 x 2 power connector is to be used.
