Skulltrail cannot do Tri SLI
 

We learned that Skulltrail eight core platform won't support Tri SLI. Skulltrail motherboard uses Nforce 100 chips that provides dual SLI capability and each chip supports two slots. As Intel has two of these chips, it can power two plus two cards and make dual or quad SLI.
