Intel is the only company still way back in the last century, as they do not offer one board with solid cap design nor using high end parts on all components. For what they offer, you pay way to much. Also the design is odd with lots of empty space on the left side and a skull which they think is cool, but it's not. The debug-LED is located behind the first PCIe x16 slot and near the CPU-area. That is the most unintelligent position we can think of, because the view of the LED is most certainly blocked by any highend cooling solution and we don't know anyone who does use the boxed CPU-cooler.



The VRM is an analog 6-phase design with some fancy stuff. While it does not look cheap it can't compete with MSI and even in idle mode the Elitegroup is more efficient. For some reason Intel does only provide a SLI bridge but none for Crossfire.


The slot design is ok, but to offer three PCIe x16 slot, does not make sense, with the third slot rated only at x2 PCIe 2.0 speed. Of course you can use any PCIe x1 card. At least this is the only board featuring all fan connectors supporting PWM-fans.


The memory slots are too close to the CPU socket. This may give you some problems with some big CPU-coolers. The board would have lot's of space, but for some reason Intel is using a super I/O controller which is only needed for sensors and fan-control.

Intel is the only vendor not using some cheap Gb solution, but of course they produce them themselves. So an i82578DC controller gives you good connection. On the other hand Intel uses an outdated PCI Firewire controller. The audio solution is of course a Realtek and the best they do offer, an ALC889. The extra two SATA ports on board and the two eSATA ports are provided by a Marvell controller.


The SATA connectors are on the edge of the board and all of them are angled at 90°. This is the best solution available because the connectors won't interfere with any cards.


The BIOS is the usual Phoenix Award BIOS, which looks really nice. All default settings are correct and Intel does supply regular updates. 

As usual, Intel clocks nearly on the spot:


At this price level we expected 4GHz to run without problems, and it did:



Of course even Intel features undervoltaging and it works well but needed 1.05VCore.
