ASRock has yet another socket LGA-1366 motherboard up its ranks: the X58 Extreme. This model is distinct from the X58 SuperComputer and X58 Deluxe, which shared the same PCB. It has three PCI-E 2.0 x16 slots, from which only two are routed to the X58 northbridge. The CPU is powered by an 8-phase circuit, similar to the other ASRock models. The blue PCI-E x16 slots are connected to the northbridge with full 16-lane bandwidth, while the third orange slot is wired to the southbridge with 4-lane bandwidth. The package bundles only the 2-way SLI bridge, and 3-way SLI is not advertised, although 3-way CrossFireX is. The ICH10R southbridge provides 6 SATA ports, while an additional controller provides IDE and eSATA connectors. ASRock's InstantBoot feature is supported. Looking at the features on offer, we expect this board to sell for a lower price than the X58 Deluxe, which is on the brink of entering the sub-$200 segment.
