Here, the users will find all the information they require to set up their CrossFire configurations. Compatibility chartĪMD has published a compatibility chart for CrossFire cards. But if you still want to crossfire the RX 580, the only card you can. Most games these days do not support crossfire anymore. Single card performance has gotten better and now multiple cards are not needed. The reason for this may be because crossfire is fading away. However, the latest generation of Radeon graphics cards integrates the XDMA technology, which eliminates the need for bridging cables (CrossFire is implemented over the PCI Express bus). The 'Crossfire compatibility Chart' has not been updated in quite a while. BUt, keep in mind that some cards use non reference volts chips, so OCing can be broken, since you can end up with 2 cards, one with voltage control and the other wo/ ibitato, 2. This ribbon-like connector is usually provided with the graphics card but can also be bought separately. as long as you respect the Ati CrossfireX compatibility chart, you are fine with any brand. Some graphics cards models will require an external bridge for the connection. All graphics cards must be of the same generation.Ī typical AMD CrossFire configuration will usually consist of 4x Single-chip AMD Radeon graphics cards or 2x Dual-GPU AMD Radeon graphics cards, which together will add up to a total of 4 GPUs. Accessories : Power Supply / Riser Card / Heatsink / System Fan / Front Chassis.

You will require a CrossFire compatible motherboard with enough free PCIe slots to accommodate your graphics cards, as well as a compatible power supply. Networking AOC Matrix : Ultra / Standard / SIOM / AIOM / MicroLP / TwinPro. The implementation of a CrossFire configuration is really easy as long as you have the right hardware components. The technology allows up to four GPUs to be used in a single computer to improve graphics performance. In short, if you have an HD 6990 and you crave even better performance, then adding an HD 6970 may save you quite some cash and allow for gaming at maximum resolutions.How to choose your AMD CrossFire Graphics card? AMD CrossFire (also known as CrossFireX) is a brand name for the multi-GPU technology by Advanced Micro Devices, originally developed by ATI Technologies.
During intensive operation however, our rig with TriFire inside consumed about 845W. Our test rig drew about 200W more with Quad GTX 590 than with the TriFire (HD 6990 + HD 6970). This means that it will draw about 125W more than HD 6970, via two 8-pin connectors. On the other hand, HD 6990 consumes around 335W and if you intend to overclock it, you should know that it can draw up to 370W. The HD 6990 card consumes around 37W in idle mode, which isn't half bad considering that a single HD 6970 consumes 22W. AMD motherboards with FM2+ socket are backward compatible with all old FM2 and FM2+ CPUs. Backward-Compatible and Future-Ready AMD Computer Motherboards. For instance, you should make sure that your TriFire rig with a HD 6990 and HD 6970 boasts a 1000W PSU. If leaks are to be believed, here are the motherboards that will be compatible with DDR5 RAM: ASUS ROG Strix B660-A Gaming.We’re sorry to say this, but the fan noise barely allowed us to enjoy our gaming sessions.Ĭonsumption is unwise to ignore when dealing with CrossFireX and SLI setups, even if you don’t care much about your power bills. We were more worried about noise, because the cards can get pretty loud in 3D mode.Īfterburner tool detected the fan seriously speeding up from time to time.

The scores show that slotting the HD 6970 next to a HD 6990 may improve performance up to almost 50%. However, we used the bios switch on the HD 6990 and boosted its GPU to 880MHz, in order to make it identical to the one on HD 6970. Note that when using two different graphics cards in CrossFireX, the faster card will downclock to the level of the slower card. The HD 6970’s GPU runs at 880MHz while the HD 6990’s GPUs run at 830MHz. List of games that support Crossfire Age of Wonders 2 Age of Wonders: Shadow Magic Air Missions: HIND, use optimize 1X1 CROSSFIREX option. So, our multi-GPU system is made of three Cayman GPUs. Nvidia 270.51_desktop_win7_winvista_64bit The following table is incomplete but gives a nice insight into CrossFireX’s capabilities.ĬPU: Core i7 965 XE (Intel EIST andVdropenabled) CrossFireX allows for pairing a dual and single GPU cards and we pounced on the chance to use HD 6990 and HD 6970. Unlike Nvidia’s SLI, AMD’s CrossFireX allows for daisy chaining a wider variety of cards. Review: HD 6990 and HD 6970 happily running side by side
