When we first saw the ASUS ROG Crosshair IV Extreme back in March, it seemed like just a beefier version of the Crosshair IV Formula with four well spaced out PCI-E x16 expansion slots, a stronger VRM, and a few more ASUS-exclusive goodies thrown in. Later in May, we learned that the Crosshair IV Extreme is different from its smaller, more popular sibling, in featuring the LucidLogix Hydra Engine chip that lets the users pair graphics cards across the lineups and GPU vendors, whichever way they want to upscale performance or add features. After quite some wait which led some of us to fear that ASUS shelved the product as Crosshair IV Formula seems to have been well received, the company surprised us by finally releasing the beast to the market.

The Crosshair IV Extreme that we see today is slightly different from the older iterations in featuring a different heatsink assembly design. It features bulkier, more groovy-looking heatsinks over the north-west cluster that houses the CPU VRM and AMD 890FX IOMMU, while the south-east cluster has a sleeker heatsink that cools the Lucid Hydra chip and the AMD SB850 southbridge. Most other features remain the same: expansion slots that include five PCI-E x16, one PCI; support for dual-channel DDR3-2000 MHz memory; a six-port SATA 6 Gb/s RAID controller, 2 SATA 3 Gb/s ports, two eSATA 3 Gb/s; connectivity that includes gigabit Ethernet, Bluetooth, 8-channel SupremeFX X-Fi audio, USB 3.0; and a boat-load of OC-friendly features including ROG Connect, redundant BIOS, on-board voltage-measure, PCI-E gating and OC controls, etc. It is priced around 300 EUR.

Interesting PWM cooler. Though it makes me wonder why ASUS doesn't make Crosshair Gene boards...
 
So, you can run any gpu combination on this mobo? crossfire, sli, ati & nvidia
 
Damm I just this morning bought the Gigabyte 890FXA-UD7 :( ahh well its still a good bored this one does look nice tho :)

Hydra doesn't give you "SLI/CrossFire", it is its own multi-GPU technology. A-mode for ATI + ATI, N-mode for NV+NV, Mixed-mode. You won't need a bridge cable.
 
Sexy. Wish I had serious funds to build a new PC. :sigh:
 
Hydra+Asus ROG=Buy

Dude thats news to me. Below is from your own news report. Am I missing something?

Following the apparently-successful launch of the ROG Crosshair IV Formula, ASUS is preparing the second, even-higher end offering under the Republic of Gamers (ROG) series for the socket AM3 platform, the Crosshair IV Extreme. First pictured and detailed in March, the Crosshair IV Extreme turned out to be a little more than just a beefier Crosshair IV Formula with a stronger VRM and more expansion slots; it has an important addition to its feature-set which was revealed after some websites pictured the board without its chipset heatsink. The Crosshair IV Extreme makes use of the Lucid Hydra engine, with a 32-lane Hydra bridge chip that supports 3~4 graphics cards. While the AMD 890FX isn't deficient of PCI-Express lanes, the addition of Hydra gives the motherboard the unique ability to mix and match graphics cards, with special modes for pairing ATI GPUs, NVIDIA GPUs, and ATI + NVIDIA GPUs. Another feature that got revealed with the heatsinks off is the CPU VRM, which makes use of no less than 11 independent phases, and a super ML capacitor that helps voltage tuning with high precision, and conditions CPU voltage better than conventional capacitors. ASUS may choose Computex as the ideal launch-vehicle for the Crosshair IV Extreme.
 
Looks like an awesome board!!! It's probably gonna cost a bunch though.

Don't even think that's possible lol

So they're implying i can run a GTX 480 with a 5850 on that board?

It's possible, due to the Hydra chip.

MailMan. What btarunr said a few posts up is just a different way of saying what you quoted.
 
So the hydra chip allows them to talk to each other, even if they are two totally different cards and architectures that are designed different is almost every way?
 
Any idea on the price?

Sexy mobo.
 
If you are not a serious OCer, I don't think its worth spending your dollars on this. New Intel architecture is coming and then you will have a blackboard in your case that is capable of nothing...

I prefer a sub $150 mobo...

For 300 EUR, you can get:

6 core AMD CPU $199
800 chipset mobo $98
4 gb DDR3 rams.... $72
HDD....
PSU...

Erm.... this is an 800chipset board :laugh: Look it's an Am3 socket :D

No, you're not. It's what I said then, and what I said now. They're both consistent.
 
I was looking forward to this board with a phenom x6 and some water cooling..... months ago :banghead: now i have had to wait so long i decided to wait for sandy bridge and if i can hold off long enough bulldozer to see if they impresses me.

If this had been out 6 months ago i would have owned one for about 6 months now, damn asus :p
 
How is scaling on the Hydra chip now? I remember reviews on the Big Bang Fuzion wasn't that great.
 
Would like to find out the measurements of mounting holes for the mobo cooling, if I were to get this that heat-pipe array would be chucked into storage before I even use it.


Lots of layers of aluminium = fail.

Well, currently, I am finding that my second 5870 is pretty useless...I'll be psoting a thread soon with BFBC2 results...might be surprising.


Anyway, if Hydra can make BETTER use of my Crossfire pair....then I'm sold. In fact, because using the second card results in lower framerates, even if they get 25% scaling, hydra wins.

I have to give this board a try...I think my Thuban might finally get removed from it's box!:laugh:
 
Disappointed in Asus that they waited so long to release this board. I was ready to buy it back in July, but now I will just wait till Sandy Bridge or Bulldozer. If Asus had made this an AM3+ board then I would be all over it.

Yes, it was planned to scale 2 or more gpus even if they have different chipsets or are made by different brands. But actually the scalling is not so good.

That article is from almost exactly a year ago(Sept 22nd, 2009). I will see how things have changed since...or if they haven't.

If you want to see real life tests of hydra there are reviews of mobos with it. Look for the msi big bang fuzion. Actually is quite dissapointing.
