ASUS has just unveiled its first G34 socket motherboard supporting AMD 8 and 12-core Opteron 6100 series processors.
Powered by AMD's SR5690/SP5100 chipset, it has support for four channels of DDR3 memory for each processor (up to sixteen separate modules in total)
and includes ASUS' proprietory PIKE upgrade kit as well as their ASMB4-iKVM module for remote management; handy in the server environment it's destined for.
Looking at the picture above, there appears to be an extensive amount of storage support on this board as well, giving fourteen SATA ports which would allow for up to 28GB of storage before even considering the need for separate PCI-E RAID controllers.
No details on pricing or availability at this point, but you can read more about it within ASUS' official PR here.
