Placing two cards in CrossfireX definitely doesn't require you to have a kilowatt PSU. The Radeon HD 5770 for what it is producing in terms of performance, is a card with a great power specification.
99% chance it's related to a residual driver installation. Typically things never go wrong, but if they do.
One last tip, especially with multi-GPU setups, please make sure you have uninstalled old drivers properly prior to installing the new cards and drivers. If you are not sure, just start up the Catalyst Control suite, go to the TAB 'CrossfireX' and make sure CrossfireX is flagged.
On the software side of things you simply need to boot into Windows, install the latest Catalyst drivers and after a reboot, in most scenarios, CrossfireX is automatically detected and enabled. This is the hardware part, and yes it is as easy at it sounds. For 3-way CrossfireX you'll need three 6-pin connectors. Make sure you hook up the power connectors to all graphics cards and connect your monitor to the Radeon HD 5770 card located closest to your CPU. You simply seat the two cards and connect the Crossfire fingers like shown below, you can find them at the top-side of the graphics card.įor two cards you use one CrossfireX bridge, for three you use two and for four cards you use three CrossfireX bridges.
