Asus Crosshair IV Extreme

CPU Performance

CPU Performance

SiSoftware Sandra (the System ANalyser, Diagnostic and Reporting Assistant) is an information & diagnostic utility capable of benchmarking the performance of individual components inside a PC.

CPU Arithmetic

The CPU arithmetic test ascertains the processor's capabilities in terms of numerical operations. Two subtests named Dhrystone and Whetstone are carried out respectively. This is not a measure of latency and thus higher is better.

Unsurprisingly, the Crosshair IV Extreme commences our testing with scores that nicely match the Crosshair IV Formula and the recently reviewed 870A Fuzion PE. As the man responsible for testing almost all of OC3D's Socket AM3 motherboards, let me assure you that these results are exactly as expected.

CPU Multimedia

The CPU Multimedia Test focuses on CPU based operations that may occur during multimedia based tasks. The magnitude of the score depends on the processor's ability to handle Integer, Float and Double data types

Once again a similar story with CPU Multimedia. Strong gains are shown by our overclock in the region of 4.00GHz.

CPU Queen

CPU Queen is based on branch prediction and the misprediction penalties that are involved.

Everest's CPU benchmark suite usually tends to offer similar outcomes. The Queen benchmark also shows a level set of results.

CPU Photoworxx

PhotoWorxx as the name may suggest tests processors by means of invoking functions that are common to Photo Manipulation including Fill, Flip, Crop, Rotate, Difference and Colour to B&W conversion.

Photoworxx performance has a tendency to fluctuate and so its often required to repeat the benchmark quite a lot to determine concordant results. Regardless, the CH4 Extreme appears to take a fair lead over the rest, while the MSI 870A holds its unusually low score.


This is an integer based benchmark that will test the CPU and Memory by means of the CPU ZLib compression library.

Equality is restored with the ZLib test. This is a particularly important test due to its operations having similarities with the likes of WinRAR.

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
