Like the Crosshair IV Formula, you can immediately tell that this motherboard is centred around Overclocking. Really who cares about Date, Time or Current Boot devices? All that matters is that the overclock menu is in front of you from the word go!

As you would expect, a whole host of Voltage and Frequency parameters are available for you to access. The flexibility on offer suits the needs of everyone from novices to dry ice/LN2 lunatics.

As with most Asus boards these days, it is possible to save and load BIOS profiles in up to 8 banks. The Crosshair IV Extreme also includes a separate BIOS Profile named "Go Button", which links with a button on the motherboard. This is convenient for those times when a particular overclock fails and you simply need to call up some fail safe defaults with minimal hassle.

Finally, the BIOS menu provides you with access to the EZ Flash 2 tool. As mentioned before, you can even load BIOS ROMs from your Hard Disk Drive, as the tool is capable of navigating through most file systems.

Good review as usual though it did seem a little short. I had a bad feeling regarding the actively cooled heatsink when i first looked at the board a few weeks back, out of interest how hot does it get when the fan is unplugged? Hydra performance is thankfully better than i expected too. At £250 its not cheap especially with AMD's new none compatible CPU's coming quite soon. Never the less I will give this board some serious consideration for my new build.Quote

I must admit that I'm not a fan of the ROG motherboards. I liked the CHIV but this one goes too far with add on crap that's all a bit pointless.

I mean sure, if you are a gadget freak then it may appeal to you, but the bottom line on a board of this cost is function. Function should come over form as it does with the MSI.

Yet it wasn't even able to match the MSI's bottom line function.

So all of the stick on tat does very little if it is being compared to what I would call a budget board.

It was the same with my CHII ROG. Loads of stupid tat (The LED poster for one) that was fun for about five minutes and then got old fast. The only thing I really liked on that board that explained away the premium price was the cmos reset on the IO shield - that was bloody marvellous. But the rest? I ended up disconnecting the LED poster after about six boots never to use it again.

And then I got my M3A32 deluxe wifi which was also a very expensive board, yet doesn't have any silly bits on and has far more to offer in the way of function.

Again I suppose Asus are going to cater to many people with this board, but what with this, the Ares, the Mars II (if it ever comes along) and that add in board previewed today I just worry sometimes that they are being a bit over indulgent and started to fritter away their successes on stupid stuff.

It's all starting to seem a little... How do you say it?... EVGA.

Sorry if I sound harsh or pessimistic, I am only thinking aloud. But I think this time MSI have shown that stuff like this and EVGA boards are all rather pointless.

Thanks ever so much as ever for the reviews guys. Quote

hi, i wanted to know if any of you readers, or even tom could tell me if this mobo is able to boot from a PCI e slot. im looking to build a system and have been hoping this board comes out, but was set on getting the formula. the only thing holding me back was the fact that it couldnt boot from pcie. i was planning on an OCZ RevoDrive ( but on the OCZ site, it states, "-Asus Crosshair IV – Please check with motherboard manufacturer for BIOS update to enable boot over PCIe." basically, with the new board, has the bios been updated to allow pci e booting? or am i still SOL...Quote
