ASUS Crosshair IV Formula Motherboard

Today we have the opportunity to take an in depth look at the ASUS Crosshair IV Formula. The ASUS Crosshair IV Formula is an AMD based motherboard that is based on AMD’s 890FX chipset. The ASUS Crosshair IV Formula motherboard is the cream of the crop when it comes to AMD based motherboards from ASUS. Though the price tag of $225 may cause some to shy away, for those that are willing to pay a premium for an enthusiast board, a premium board is what you will get! Though before we look at the ASUS Crosshair IV Formula, let’s take a look at the AMD 890FX chipset that is used on it. AMD officially announced the 890FX chipset back in April; this happened to concur with the release of the new Phenom II X6 processors. The 890 series and the Phenom II X6’s combined with the Radeon HD 5000 series graphics card make up the new Leo platform. One of the features of the AMD 890FX chipset that differs from the previous generations of chipsets is the memory configurations. When using the AMD 890FX chipset you will be limited to using DDR3, although the Phenom II X6’s are still able to be placed in AM2+ platforms that will take advantage of DDR2.

AMD 890FX Chipset

AMD’s 890FX chipset has a couple of significant differences when compared to the 890GX chipset. The first and most obvious on the ASUS Crosshair IV Formula is the lack of onboard graphics while the 890GX features the Radeon HD 4290 integrated graphics. The second and quite possibly the most important to the enthusiast looking for the best performance from the ASUS Crosshair IV Formula when running in CrossfireX is the number of PCI Express lanes. The 890GX chipset is limited to 16 lanes while the 890FX chipset has double that at 32 lanes. Most people will most likely never notice a difference unless of course you are one of the lucky ones that can afford a pair of ATI Radeon HD 5970’s or one of the insane ones who is lucky enough to pick up a pair of the ASUS ARES. Another significant difference is the IOMMU (input/output memory management unit). This is a feature that is typically available only on server boards, though is included in the 890FX chipset only when comparing the 8xx series chipsets. According to AMD: The IOMMU (input/output memory management unit) included with the 890FX chipset is a function of a chipset that enables enhancements to system-level software and that prevents illegal access of memory by I/O devices. By preventing illegal access of memory, the IOMMU can prevent problems with latency.
An IOMMU can map device memory addresses to physical memory addresses, but in a manner that is transparent to the device hardware. The IOMMU automates the translation between the physical address of the I/O device and the host system.

Though I digress, the ASUS Crosshair IV Formula is the fourth board in the ASUS Crosshair series. For those that are new to the enthusiast scene or that are beginning to realize that yes, AMD is pushing out products with some serious performance. The Crosshair series is the top of the line boards from ASUS. With features such as ROG Connect, GameFirst, Loadline Calibration, Extreme Tweaker and many more features offered by the ASUS Crosshair IV Formula we have a lot to cover. Below is a down and dirty specifications chart and on the next page we will start looking at the features much more in depth.
