Asus Crosshair IV Extreme
The Board Continued...
If you're surprised that this motherboard is Extrended ATX, don't be. The Crosshair IV Extreme is brimmed with features, which consume valuable PCB space.
The top right corner of the motherboard is populated by a number of features.
First of all, there's Asus' recent ProbeIt implementation. Here, overclocking enthusiasts can directly access voltage readings with a multimeter. You may either access them directly from the PCB, or if you're a little worried about digging a trench in your expensive purchase, you may also use the included wire adapter.
Next up are the five flick switches above the ProbeIt ports. This is a diagnostic feature that allows you to enable/disable PCI-Express ports. This may not seem like much, but you'll want to shake hands with Asus after it helps you find the faulty graphics card in your three way Radeon HD 5870 setup!
The "GO" button has two uses. Using the feature can be used to recover the system from a memory related boot failure. It is designed to fine tune memory parameters in order to reach a bootable state once again. The feature can also be associated with a "GO" profile within BIOS.
Last but not least, Asus have also implemented Power Toggle, Restart and instant "Core Unlock" buttons on the PCB.
The placement of PCI-E 16x ports ensures that 2, 3 and 4 card arrays of GPUs are possible, regardless of their shape and size.
The Crosshair IV Extreme allows you to install up to eight SATA 6Gbps devices; 6 are powered by the SB850 Southbridge while the others are linked to a separate Marvell controller.
We also have an updated heatsink array in town. Turn over and we'll have a brief chinwag about it...
