Asus Crosshair IV Extreme


Asus Crosshair IV Extreme


At last the 30th September has arrived; at the beginning of the month we received Asus' range topping Crosshair IV Extreme motherboard. Within just a few days we released another article, which confirmed the rumours that surrounded the motherboard last May. Sadly there was only so much we could mention due to the strict Non Disclosure Agreement issued by Asus, but thankfully today is the big day. As of this morning it should be possible to purchase one of these supposed gems, but after days of testing, what do we think of it?

We all know that budget is not a term associated with the Republic of Gamers brand and unsurprisingly the Crosshair IV is no exception. As always one would expect a level of innovation in a board that's set up to be one of the best or at least set of features that helps it stand out from the rest.

So what exactly does this hefty share of your pay cheque buy you?

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

PCIE booting is not something we test for so Im affraid you will have to look on the Asus website for specifics dude sorry Quote
