This is similar to X1300 CrossFire, which also uses PCI Express, except that the Xpress 3200 had been built for low-latency and high-speed communication between graphics cards. With the CrossFire Xpress 3200, two normal cards can be run in a Crossfire setup, using the PCI Express bus for communications. When used with ATI's "CrossFire Xpress 3200" motherboard chipset, the "master" card is no longer required for every "CrossFire Ready" card (with the exception of the Radeon X1900 series). The next generation of CrossFire, as employed by the X1800 Master cards, used two sets of compositing chips and a custom double density dual-link DVI Y-dongle to double the bandwidth between cards, raising the maximum resolution and refresh rate to far higher levels. As many people found a 60 Hz refresh rate with a CRT to strain one's eyes, the practical resolution limit became 1280×1024, which did not push CrossFire enough to justify the cost. This was considered a problem for CRT owners wishing to use CrossFire to play games at high resolutions, or owners of Widescreen LCD monitors. Because it used a compositing chip from Silicon Image (SiI 163B TMDS), the maximum resolution on an X850 CrossFire setup was limited to 1600×1200 at 60 Hz, or 1920×1440 at 52 Hz. The "slave" graphics card needed to be from the same family as the "master".Īn example of a limitation in regard to a Master-card configuration would be the first-generation CrossFire implementation in the Radeon X850 XT Master Card. ATI currently has not created the infrastructure to allow FireGL cards to be set up in a CrossFire configuration. Low-end Radeon x1300 and x1600 cards have no "CrossFire Edition" but are enabled via software, with communication forwarded via the standard PCI Express slots on the motherboard. This dongle serves as the main link between both cards, sending incomplete images between them, and complete images to the monitor. The Master card shipped with a proprietary DVI Y-dongle, which plugged into the primary DVI ports on both cards, and into the monitor cable. One had to buy a Master card, and pair it with a regular card from the same series. "Master" capability is a term used for 5 extra image compositing chips, which combine the output of both cards. Radeon x800s, x850s, x1800s and x1900s came in a regular edition, and a "CrossFire Edition" which has "master" capability built into the hardware. The system required a CrossFire-compliant motherboard with a pair of ATI Radeon PCI Express (PCIe) graphics cards.
