ASUS Finally Releases ROG Crosshair IV Extreme Motherboard

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.

Well then I'm confused. The way I read it is I can combine a 480 with a 5850 for some kind of hybrid GPU setup. This could be beyond say an X58 chipset which can do Crossfire and SLI.

Am I right? If not enlighten me.
Yes you can do that man, it's just not called Sli/Crossfire was all BTA was saying.

If you're rich enough to buy that board, why not buy the Extreme and then sell your current board?

Yes, you're right. You can pair an NV card with an ATI card in mixed mode, as I mentioned in the news post.

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 (A Mode), NVIDIA GPUs (N Mode), and ATI NVIDIA GPUs (Mixed Mode).
Neither A or N modes use SLI or Xfire Tech to coordinate between the 2(+) cards, its all Lucid's own design and implementation.

At this time it's like this: SLI > CFX > Hydra modes.

The future of Hydra is not very certain, their drivers aren't that good yet, they made promises they didn't fully fulfilled. Scaling in most situations is ok-ish to bad. In some (few, but they exist) situations you don't even get the performance of one card.

So I would stay away from them for now, unless you have money to blow on experiments.

The best option for multi GPU setups in the market is X58. If you're just into CFX, you can get away with an AMD board. But I like to have options.

My confusion was in the terminology.

You are right they cannot do crossfire or SLI but a Lucid version of the two. Thanks BTA and theonedub.

My weapons grade stupid is explosive.

Can you bypass Hydra driver installation, and just use standard Crossfire for 2 ATI cards?

And what is their scaling in N mode like? Can this bring a near SLI experience to the AMD chipset?

Do want finally it has come out. Wish they would have kept the one pci-e x1 slot they had. I think this will be in intels echelon of pricing on high end boards, like 350 or so.

W1zz needs to review one of these Hydras already.

If you have patience to go through Google translate you can see a review from my friends here. Original article in Romanian.
This is the first part. Second part will be about LucidLogix Hydra 200 and SLI/Crossfire configurations.
