The board is pretty standard for ASUS.  If you believe ASUS marketing with it's 16-phase VRM, just forget it, because that's only 4-phases quadrupled. As we and many other sites said before, this is just not the way to go. It uses more power, is not more stable compared to other solutions and has no benefit whatsoever.

The unique feature is the voltage monitoring on the bottom of the board and with many overclocking buttons. While for some overclockers this feature brings benefits, we think it's just a way to increase the price of such boards. We also don't think it's wise to overclock when the system is running, because it does strain components on the board.

For some reason most vendors went for triple PCIe x16, so they can say the do support Triple-SLI. But you can have only two slots at full speed, adding a third card, two of the slots will only run with half the speed. Also only the first black PCIe x1 slot can fit the added soundcard, which is not an X-Fi, but just an ADI2000B chip with some EAX. The second PCIe x1 is just useless, most high-end graphics cards use at least two slots. This should be the high-end dream from ASUS, but we simply can't grasp why they put a PCI FireWire controller on it. At least ASUS stays with Marvell LAN chips, they do perform better compared to any Realtek chip.
The board does not clock at nominal speeds, which is a shame.




ASUS provides auto-overclocking of any CPU, but we advise against it. As we can show, it increases VCore massively and if you don't want invalidate the warranty of your CPU, you should know know better.


So we did it manually and the results where quite satisfying.


The i7 920 does not provide unlocked multipliers, so we test each board with a BCLK of 173MHz. While the auto-overclocking feature sets the VCore to 1.3000V (screenshot), we managed to get a stable system with 1.2500V.
