CrossFire

CrossFire Introduction

CrossFire technology allows a pair of graphics cards to be used in a single

computer to improve display performance, creating a high-performance gaming

platform. CrossFire works with all 3D games and applications.

Performance enhancements experienced on a CrossFire system depend on the

application or game being used. Performance improvements of up to 100% have

been recorded. The latest graphics-intensive programs will generally see over

80% performance improvement at high resolutions and high image-quality

modes. If ATI Catalyst™ A.I. is enabled in the ATI Catalyst Control Center

software, the optimal rendering mode available for the application is

automatically selected.

CrossFire Requirements

The requirements of a CrossFire system are:

• A CrossFire-ready motherboard.

• Two CrossFire-ready graphics cards.

• CrossFire connections for card-to-card communications (come with your

cards)

In addition, a 550 watt or better power supply is recommended.

For an up-to-date listing of CrossFire certified motherboards and power supplies,

and CrossFire configurations, see ati.amd.com/products/certification

Note: A second CrossFire interconnect cable is required to support 3D

resolutions above 2560 × 1600 at 60 Hz for LCD monitors and 2048 × 1536 at

66 Hz for CRT monitors.

Install CrossFire Graphics Cards

These instructions assume that a PCIe® graphics card has already been

successfully installed in the secondary slot (slot one), and that the primary slot

(slot zero) is empty.

Note: Consult your system builder or OEM to ensure that your system has

an adequate power supply. A 550 watt or greater power supply is

recommended.
