•Currently, only AMD® HD3470, HD3450, HD2400XT and HD2400Pro graphics cards support the Hybrid CrossFireX�™ function���������.

•If you install two VGA cards, we recommend that you plug the rear chassis fan cable to the motherboard connector labeled CHA_FAN1 or CHA_FAN2 for better thermal environment. See page 2-28 for the connector location.
