Overclocking and Conclusion
Overclocking

    Asus has been excelling at overclocking for some time now, and this board is no different.  I was able to take the standard 1090T and clock it up to 4.1 GHz with few problems.  Stability is best around 4 GHz.  This is right in line with most other boards I have tested, and is about the max for the CPU that I have.

    The HTT could be clocked up to 320 MHz on the board, but not without a few hiccups.  The usual dead space between 245 and 260 reared its ugly head, as well as the area around 285 Mhz to 300 MHz.  Other than that, it was fairly simple to get to any of the speeds beyond those areas.

    Overall stability at overclocked speeds is good, and the huge variety of BIOS settings essentially ensures that anything that can be tweaked will be tweaked.  Memory can be pushed above 2000 MHz with the right DIMMS installed.

Conclusion

    I have to admit I ended up really liking this board.  The design really grew on me, the performance is top notch for an AMD board, and the featureset is again without parallel.  The board runs cool and really does not suck up that much extra power as compared to other, lesser featured units.

The board all pimped up and ready to go.

    While I do not think the PCI/PCI-E slot layout is truly optimal, it does work around other issues that competing boards exhibit.  As long as only one graphics card is used, the other three PCI-E slots can be used (two of which would be x8 and the bottom would be x4 if all three were populated).

    The board was stable throughout testing, and the latest BIOS improved performance here and there when dealing with memory and SATA.  Overclocking is very easy on this board, and the extras like ROG Connect should really help to push this over the top with users willing to go to extremes for overclocks.

    The software bundle with the board is very good as well.  While I am not entirely in favor of Turbo-V (I like to use the BIOS to overclock more than using software suites), it works very well for those wanting to dip their toes into pushing their hardware.  It also comes with a copy of Kaspersky Antivirus, which is an added bonus in these uncertain times.

The only major change in retail boards is that the 12v CPU power supply plug is now located slightly farther away from the heatsink.

    The only real downside to this board is the price as compared to some of the competition.  It retails at $229, which is $30 more expensive than the comparable MSI 890FXA-G70.  It is often on special, and can be found for $199 regularly.  Asus typically does charge a small premium for their boards as compared to other manufacturers, but in this case it really is not that much.  Especially considering the extra features Asus included in the board like ROG Connect.

    Unlike the previous Crosshair III, which really was not that much of an upgrade over their standard 790FX board, the Crosshair IV takes design to a whole new level.  The added features, greater usability, and outstanding overclocking features and performance make this one of the premier AMD boards out there.  It is very much on the same level as the MSI 890FXA-G70, but the two have enough differences between them so as to offer something unique to the user.  But at least with the Crosshair IV I did not run into that annoying “auto-detect” issue for the front audio plug-in that I did with the MSI board.
