ROG Zenith Extreme spills some beans on Ryzen Threadripper
 

AMD is still playing coy about its upcoming Ryzen Threadripper CPUs, but Asus isn't afraid to show off its ROG Zenith Extreme mobo for those chips. This motherboard uses AMD's forthcoming X399 chipset and TR4 socket, built specifically for Threadripper. The Zenith Extreme has eight DDR4 DIMM slots for use with X399's four memory channels and four metal-reinforced PCIe 3.0 x16 slots to use with as many as 64 PCIe 3.0 lines provided by the Threadripper CPUs.
