Asus Crosshair IV Extreme AMD 890FX Motherboard

1 thumbs up

One of the unfortunate consequences of AMD's inability to match Intel's performance at the ultra high-end of the CPU market over the past few years is that there's been a substantial decline in the number of high-end AMD motherboards. NewEgg presently stocks just two AMD motherboards in the $200-$300 price range compared to 36 Intel products. That's not to imply that you have to pay $200 or more for a quality motherboard but it clearly implies that when motherboard manufacturers are thinking about enthusiasts, they're also thinking about Santa Clara.

With one exception.

Both of the $200+ AMD boards are built by Asus and the company recently sent us its top-end AMD offering. The motherboard's retail price point of $299 dwarfs anything else anyone offers in an AMD flavor these days, but Asus has packed the Crosshair IV Extreme with every goody you can think of.

Form Factor

The Crosshair IV Extreme isn't actually an E-ATX motherboard, but its width of 10.6" is one inch wider than the official ATX spec supports. To determine if the board will fit in your case, measure one inch from the last set of mount spacers on the right and add at least a few tenths of an inch for wiggle room. Most cases will support the board, but those with interiors that conform to the ATX spec with laser-cut precision are out-of-luck.

The Crosshair IV Extreme, like most high-end boards these days, is explicitly aimed at the ultra-high-end overclocking crowd and offers a number of OC-friendly features in an attempt to court this rare species of computer enthusiast. Because so few users actually push their systems as far as that group, we'll be explicitly evaluating the CIV-Extreme's features that might prove useful to the more typical user and thus help justify the higher purchase price to a broad audience.

That is a pretty mother board. The components etc are exceptional of course, but they have done a very good job with this one designing it.

hi problem with Zotac gtx 560 sli edition amp you in Mother  Asus crosshair IV extreme plz help me!!

Grone,

I'll try, but it'll help if you speak more clearly. If English isn't your first language, try using Babelfish or Google to translate. Troubleshooting hardware can require fairly precise explanations of what's going wrong and what the solution might be. If you can't get help or use a translation service, I'll still try to work with you.

Now I'm using the translator, I'm Uruguayan, my problem is I can not enable sli on my pc.
My pc: Motherboard: Asus crosshair extreme IV
           
Video Card: Zotac GTX 560 Amp "x2
           
AMD Black 1090T series
           
H50 Series Hydro Corsair Cooler
           
MUSHKIN 2x4 Red Line 2133 mhz
          
PS Cooler Master Siletn Pro Gold 1000w
           
Sli Band "MSI"
          
SO 64 bit Win 7
I got all things properly installed, install the operating system, install all driver Palca mother, then put my two graphics cards in slot 1 and 3 with his band sli. Then install the latest drivers for graphics cards. panel then went to Nvidia and I appeared the opsion Sli, although the operating system recognized the two videos I did not give me the opsion Sli, after I download TechPowerUp, and appeared the two videos but where should that said otherwise sli enabled . Research on the web and someone suggested that SLI patch discharged.
Download it, follow the installation instructions correctly, restart the pc opsion gave me the two operating systems, including the right, between the panel and they can see the opsion Nvidia Sli click on apply, then this is the problem, I again the desktop and disappears Nvidia Panel, verify Control Panel / Device Manager and another of the videos with the exclamation point, as if he had the driver installed.
I await your response.

Grone,

Sorry for the delay, I made a 600 mile move between when I first responded and the present day.

The Asus Crosshair IV Extreme doesn't support NVIDIA's SLI. It uses a different technology to enable 2x NV cards to run side-by-side. This technology is known as LucidLogix Hydra.

Here's what you do:

Do NOT use Slot 3 for an SLI configuration. Use 1 & 2 or 1 & 4. Hydra doesn't work with Slot 3.

Install these drivers: http://www.lucidlogix.com/driverdownloads-driver4.html

After drivers are installed and rebooted, click on the new HydraLogix icon. Make sure Hydra is set to Enabled / On.

If you want to see if a game is working properly, you can also enable an overlay to show you cross-GPU scaling.

NVIDIA's drivers will *not* offer you an option to enable SLI. That's ok.

Thank you very much for your help, but I have a question placed on dual chanel Muskhin my memories of 2133, if placed in slot 3 a transcendence of 4 GB 1333 Mhz open any problems or decreased performance due to incompatibility?

Grone,

What languages do you speak? It might help me understand if you typed in your language and I could translate it. Maybe send me an email? Also, use very short, simple sentences.I'm not trying to make you feel bad--tech talk never translates very well.

Here's what I think you said.

1.  You have Mushkin DDR3-2133.

2.  You ask about Slot 3. When I talk about Slot 3, I mean the video card slot.

3.  I have said nothing about RAM slots.

4.  You ask: Will more than 4GB of DDR3-2133 work properly?

5. According to Asus, the only RAM that officially works at DDR3-2133 is GSkill F3-17066CL9D-8GBFLS. That's two sticks of 2GB each for a total of 4GB or less.

That doesn't mean your Mushkin RAM won't work, but you may have to adjust voltages, RAM latencies, or lower the RAM clock speed. The difference between DDR3-1066 and DDR3-2133 in *real* software performance is quite small. That's true for both AMD and Intel CPUs, the only benchmarks that really show differences are either A) Synthetic or B) Gaming-intensive tests running at very very low details.

You can download the support sheets for RAM at various speeds here:  http://www.asus.com/Motherboards/AMD_AM3/Crosshair_IV_Extreme/#MSL

This is fantastic i have been waiting for a long time for a high end amd motherboard, depending on the success of this model we could see a swing in the quality and view that people put on amd as a brand and upon asus as a motherboard pioneer.

ASUS and their Black & Red theme on their motherboard is my type

Best color combo ever, who else think the same?

Go Republic of Gamers! ♥
