EVGA have slapped the performance/enthusiast world with a shocker: the SR3, dual-socket LGA2011 2P enthusiast desktop/workstation motherboard in the E-ATX form factor. Socket 0 is wired to eight DDR3 DIMM slots (two DIMMs/channel) while socket 1 to four slots (1 DIMM/channel).
In LGA2011 2P systems, the processor residing in socket 0 is wired to the PCH, while the processor sitting in socket 1 is wired to the one on socket 0 using two QPI links, closing the daisy-chain. Socket 0, apart from its 4GB/s DMI link, sports a PCI-Express 2.0 x4 (another 4GB/s) link to supplement the DMI link, this is so the storage controllers don't get bottlenecked with just DMI.
Both processors contribute to the PCI-Express lane budget of the motherboard. The board features seven PCI-Express x16 slots, which four are capable of PCI-Express 3.0 x16, every slot is PCI-Express 3.0 x8 capable. NVIDIA 4-way SLI support is there, and the motherboard is set to support Sandy Bridge-EP Xeon processors.
Each CPU socket is powered by a 6+1 phase digital PWM circuir driven by CPL+Volterra components, the memory is powered by an 8-phase (1 phase per channel) digital PWM. Continuing on the power details, we have the standard 24-pin ATX connector, two 8-pin EPS connectors, and three 6-pin PCIe connectors. Each PCIe slow can be individually toggled (disabled/enabled), by gating its power lane using DIP switches on the board.
Also included is consolidated voltage measurement points, and UEFI - so overclockers, get ready.
Storage wise, we have 14 SATA ports, and a few eSATA ports. 8+2 channel HD audio, two Gigabit Ethernet connections, USB 3.0, Bluetooth and EVBot support.
