and workstation applications. The 3-channel DDR3 architecture boosts system
performance, eliminating bottlenecks with peak bandwidth of up to 37.5GB/s. This
voltage reduction limits the power consumption and heat generation of DDR3
which makes it an ideal memory solution. Also, the motherboard can support LR-
DIMM (Load reduced DIMM) which uses a specially designed buffer to reduce the
data load to a single load and can increase overall server system memory capacity.
PCIe 3.0
The motherboard supports the latest PCIe 3.0 device, which doubles the delivered
bandwidth of PCIe 2.0. This enhances system performance while still providing
backward compatibility to PCIe 2.0.
Intel®82574L Gigabit LAN Solution
This motherboard features the built-in dual server class Intel®Gigabit LAN ports,
which helps reduce CPU usage, thus increasing throughput to achieve highly-
reliable network connections, outstanding performance, and better support for
diverse operating systems.
