2speed to guarantee the performance and compatibility of GPU graphics add-in cards. AndNVIDIA NF6100-400(MCP61V) PPC motherboard series offer one 1-LANE PCI-Express x16graphics slot of 512Mbyte/sec concurrently to guarantee the compatibility of all PCI ExpressInterface compatible add-in cards. The whole series carry two 32-bit PCI slots guarantee therich connectivity for the I/O peripheral devices. One PCI Express x1 I/O slot offers512Mbyte/sec concurrently, over 3.5 times more bandwidth than PCI at 133Mbye/sec(onlyfor 2-DIMM design motherboard).Embedded USB controller as well as capability of expanding to 8 of USB2.0 functional portsdelivering 480Mb/s bandwidth and rich connectivity, these motherboards meet the futureUSB demands which are also equipped with hardware monitor function on system to monitorand protect your system and maintain your non-stop business computing.Some special features---CPU Thermal Throttling/ CPU Vcore 7-shift/ CPU Smart Fan / /Optional BIOS BACK Function (Only for 4-DIMM design motherboard) in this motherboard aredesigned for power user to use the over-clocking function in more flexible ways. But pleasebe caution that the over-clocking maybe cause the fails in system reliabilities. Thismotherboard provides the guaranteed performance and meets the demands of the nextgeneration computing. But if you insist to gain more system performance with varietypossibilities of the components you choose, please be careful and make sure to read thedetailed descriptions of these value added product features, please get them in the comingsection.1-1.1 Special Features of MotherboardCPU Thermal Throttling Technology---(The CPU Overheat Protection Technology)To prevent the increasing heat from damage of CPU or accidental shutdown while at highworkload, the CPU Thermal Throttling Technology will force CPU to enter partially idlemode from 87.5% to 12.5% according to preset CPU operating temperature in BIOS (from 40℃ to 90℃). When the system senses the CPU operating temperature reaching the presetvalue, the CPU operating bandwidth will be decreased to the preset idle percentage to cooldown the processor. When at throttling mode the beeper sound can be optionally selected toindicate it is in working.CPU Smart Fan---( The Noise Management System )It’s never been a good idea to gain the performance of your system by sacrificing its acoustics. CPUSmart Fan Noise Management System is the answer to control the noise level needed for now-a-day’shigh performance computing system. The system will automatically increase the fan speed when CPUoperating loading is high, after the CPU is in normal operating condition, the system will low downthe fan speed for the silent operating environment. The system can provide the much longer life cyclefor both CPU and the system fans for game use and business requirements.CPU Vcore 7-Shift--- (Shift to Higher Performance)The CPU voltage can be adjusted up by 7 steps for the precisely over-clocking of extra demandingcomputing performance.BIOS BACK Function (Option)--- ( The BIOS Backup and Recovery Function )With the new support for the Serial Peripheral Interface, the whole motherboard series areembedded with the new storage of the extra bin file for BIOS recovery. When unexpectederror occurs, even the BIOS crashes down, you can restore your BIOS with just simplyclicking to restart your system. The backup bin file will recover automatically within a fewminutes(Only For 4-DIMM design motherboard)
