Crossfire Motherboard

Crossfire can best be described as a relatively new form of technology that will allow the use of two graphic cards in a single computer system. By using two graphic cards you will find that your PCs graphics and their output will be dramatically boosted. However, in order to use crossfire, it will be necessary to have a specific motherboard that is compatible with crossfire. In addition to this you will also need a crossfire master card and a regular ATI graphics card. ATI are, of course, the manufacturer of crossfire.

ATI first introduced crossfire technology in 2005 and their intention was to boost a system’s graphics capability by using two graphics cards within a single system. When they first released this new form of technology, there were only two ATI type master cards available in the marketplace. These were the X800 and the X850. In order to use crossfire the second card must belong to the same family of card as the actual master. Therefore, this will allow you to use any variant of the X800 alongside the X800 crossfire master card. This would also allow the master card to configure itself automatically in line with the exact same technologies that can be found on the opposing card.

The earliest forms of crossfire enabled cards would externally connect themselves through a pass through connector. This, in turn, would allow the slave card to be connected to the master card via a TVI output. You would typically find that the crossfire master card would have a specific decoder chip. This would actually allow any signals received from the slave card to be perfectly combined with the actual data that is produced by the master card. However, with that said, the modern day crossfire graphics cards are typically connected internally by the use of a bridge cable. Nowadays the majority of crossfire enabled motherboards are actually enabled via the BIOS.

Crossfire will allow an alternate frame rendering (AFR) which will use two Rage 128 graphics chips in order to render alternate frames. You will actually find that one card will render odd-numbered frames, whilst the other will render the even-numbered frames. Crossfire is also typically used for “scissoring”, which will divide the screen into two areas, meaning that each half will require more or less the same amount of work to produce. Each card respectively will be able to create a one part of an image and the slave card will then send all the data for to the master card before merging together and displaying. Crossfire also has a mode known as “supertiling”. This will literally divide your PC screen into numerous sections that will vaguely resemble a chessboard. Each graphics card will then set about processing alternate squares that can be found on the board. However, you should be aware that supertiling mode is typically only available in certain games that make use of 16 pixel pipelines. Another mode of crossfire is known as “super AA”. This is where the two graphics cards will perform anti-aliasing in order to increase the quality of image and, indeed, produce a far smoother image.

Crossfire has come a long way since the early days as it was extremely difficult to build a PC enabled with crossfire as there was a severe shortage of master cards. In order to overcome this, ATI initially released an Xpress 3200 motherboard chipset. This allowed the full utilization of crossfire systems, and when used in conjunction with certain graphics cards there was no need for a dedicated crossfire master card. However, since then crossfire technology has come a long way, although you should be aware that some very powerful cards will also require the use of a connector cable inside the PC. The connector cable will need to be used in conjunction with a master card.

During 2006, ATI produced a crossfire system that enabled the formatting to perform certain physics calculations. This was done by linking the two cards in crossfire mode with a third card, which would then be able to carry out the specific physics calculations. However, it was then found that this would require such a huge setup and also 3 PCI express x16 motherboards and was, therefore, likely to have an extremely high price tag. ATI crossfire is now considered the ultimate multi-GPU performance gaming platform. As mentioned, in order to set up a specific ATI crossfire you will need to have a motherboard that supports crossfire, as well as two video cards that are able to match the exact engine clocks and memory speeds. Once you have all these accessories to hand, you will find it extremely easy to install and set up your ATI crossfire via your PCs applications.
