DDR3 memory support
The KCMA-D8 supports UDIMM and RDIMM DDR3 memory that features data
transfer rates of 1333/1066/800 MHz to meet the higher bandwidth requirements
of server and workstation applications. The 2-channel DDR3 architecture boosts
system performance, eliminating bottlenecks with peak bandwidth of up to 21GB/s.
Furthermore, the supply voltage for the memory is reduced from 1.8 V for DDR2 to
just 1.5V for DDR3. This voltage reduction limits the power consumption and heat
generation of DDR3 which makes it an ideal memory solution. The motherboard
also supports 1.35V DDR3 LVDIMMs.
PCIe 2.0
This motherboard supports the latest PCIe 2.0 device for twice the current speed
and bandwidth. This enhances system performance while still providing backward
compatibility to PCIe 1.0 devices.
Intel 82574L LAN Solution
®
The motherboard comes with dual Gigabit LAN controllers and ports which provide
a total solution for your networking needs. The onboard Intel 82574L Gigabit LAN
controllers use the PCI Express interface and could achieve network throughput
close to Gigabit bandwidth.
Serial ATA II technology
The motherboard supports the Serial ATA II 3 Gb/s technology through the
Serial ATA interface and AMD SP5100 chipset. The Serial ATA II specification
provides twice the bandwidth of the current Serial ATA products with a host of new
features, including Native Command Queuing (NCQ), Power Management (PM)
Implementation Algorithm, and Hot Swap. Serial ATA allows thinner, more flexible
cables with lower pin count and reduced voltage requirements.
USB 2.0 technology
The motherboard implements the Universal Serial Bus (USB) 2.0 specification,
dramatically increasing the connection speed from the 12 Mbps bandwidth on USB
1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is backward compatible with USB 1.1.
Temperature, fan, and voltage monitoring
The CPU temperature is monitored to prevent overheating and damage. The
system fan rotations per minute (RPM) is monitored for timely failure detection.
The chip monitors the voltage levels to ensure stable supply of current for critical
components.
