Use CrossFire™ to combine the power and performance of two or more Visual Processing Units to drive a single display. Harness the power of a dual PCI Express« based computer to deliver up to twice the VPU performance when using 3D graphics applications.

<p class="pBody">
The CrossFire™ aspect requires the following to be present:
</p>
<div class="pSmartList1"><ul class="pSmartList1">
<div class="pSmartList1"><li>a motherboard with two PCI Express« X16 slots</li></div>
<div class="pSmartList1"><li>a CrossFire™ Edition Series graphics card</li></div>
<div class="pSmartList1"><li>The Radeon« X850 CrossFire™ Edition can be paired with any standard Radeon« X850-based graphics card, or</li></div>
<div class="pSmartList1"><li>The Radeon« X800 CrossFire™ Edition can be paired with any standard Radeon« X800-based graphics card.</li></div>
<div class="pSmartList1"><li>An interconnect cable, supplied with the CrossFire™ Series graphics card, connecting the two cards to a single monitor.</li></div>
</ul></div>
<p class="pBody">
When CrossFire™ is enabled, any <span style="font-style: italic">one</span> of the four following display modes are available:
</p>
<div class="pSmartList1"><ul class="pSmartList1">
<div class="pSmartList1"><li>SuperTiling - A graphical load-balancing scheme where CrossFire™ renders alternate small 32x32 pixel squares in a fine-grained checkerboard pattern. This configuration increases image rendering quality, as each card processes half of the complex 3D objects in the pixel squares.</li></div>
<div class="pSmartList1"><li>Scissor Mode - A graphical load-balancing scheme where two graphical cards are used to render two halves of an image display. One graphics card renders the top half of the screen while the second graphics card renders the bottom half.</li></div>
<div class="pSmartList1"><li>Alternate Frame Rendering - A graphical load-balancing scheme where two graphics cards are used to render alternate frames of the display. This configuration increases the detail of the 3D objects each card can render, as each card handles half of the total number of frames.</li></div>
<div class="pSmartList1"><li>Super Anti-aliasing - A feature that improves image quality by combining the results of full-screen anti-aliasing across two graphics cards in a CrossFire™ configuration. The two graphics cards work on different anti-aliasing patterns within each frame. </li></div>
</ul></div>
<p class="pBody">
It is recommended that Catalyst™ A.I. is enabled because it selects the preferred rendering mode for target applications. For applications that are not identified in Catalyst™ A.I., or when Catalyst™ A.I. is disabled, default CrossFire™ rendering modes are used.
</p>
<p class="pBody">
By default, either SuperTiling or Scissor modes are applied, depending on the application. Alternate frame rendering mode is used for applications identified in Catalyst™ A.I. when enabled. Super Anti-aliasing is enabled through the Catalyst™ Control Center.
</p>

</ul></div>
<p class="pBody">
Clicking<b class="cBold"> </b>Discard<b class="cBold"> </b>applies to all features of an aspect, not just the feature in the current view.
<div class="pSmartList1"><li>Connect the DMS-59™ connector of the interconnect cable to the DMS-59™ connection on the Master card.</li></div>
<div class="pSmartList1"><li>Connect the DVI-I connector of the interconnect cable to the DVI-I connection on the Slave card.</li></div>
<div class="pSmartList1"><li>Connect the remaining DVI-I connector of the interconnect cable to your monitor.</li></div>

<p class="pIndented1">
Note: On graphics cards with two DVI-I connectors, only one DVI-I connector on the Slave card supports Transition Minimized Differential Signaling (TMDS) required by CrossFire™. If CrossFire™ does not appear in the Catalyst™ Control Center or is not available, try connecting to the second DVI-I connector on the Slave card.

Graphics card with different amounts of memory can by used with CrossFire™. However, restarting your computer is required. This will cause CrossFire™ to reduce the amount of memory on the card with the most amount of memory to match the memory size of the graphics card with the least amount of memory.
</p>
<p class="pBody">
Clicking <span style="font-weight: bold">OK</span> to the memory mismatch error message will restart your computer.
</p>
<p class="pIndented1">
Note: When disabling CrossFire™ you will be given the option to restart your computer to restore the original graphics memory size or continue with the reduced memory size.

A recommendation message to reverse the graphics card positions may appear if the master graphics card is not installed into the primary PCIe™ slot. Although CrossFire™ can be enabled, performance may be improved by reversing the graphics card in the computer.
</p>
<p class="pBody">
See you motherboard's manual to determine which is the primary PCIe™ slot.
