TweakTown spotted an Intel server with DDR4 at Kingston's CES 2014 booth. The system probably featured Intel's Grantley-EP and Wellsburg PCH, it contained 384GB of DDR4 memory.
In order to recieve clearance for this demo, Kingston had to black out key areas of the chassis, which means essentially everything other than the heat sinks and DDR4 sticks. We speculate this is Grantley-EP and Wellsburg PCH. If so, the server supports Thunderbolt and features DDR4 speeds of 2400 and 3200MHz. However, these specs are pure conjecture.
Of course we tried to 'play the angles' to get a view underneath at the new unnannounced chipset. Unfortunately, Kingston delivered on their promise to Intel by making a more detailed analysis of the chipset impossible through use of the large black covers underneath the plexiglass cover.
