Title: How many cards does Crossfire support? Post by: nipponese on January 09, 2014, 02:05:11 AM I have seen a few cards out there (like the ASUS Rampage IV Extreme LGA 2011 (http://www.amazon.com/Rampage-IV-Extreme-Extended-Motherboard/dp/B0061XSBZ6/ref=pd_luc_sbs_02_04_t_lh?ie=UTF8&psc=1)) that carry 4+ 16x PCI-e slots. In fact, the Rampage IV Extreme carries seven.
I am not familiar with Crossfire, but it's my understanding that the max number of GPUs this feature will support is four. Does this mean I can only mine with four cards per board?

If you enabled it during mining, it will actually make you lose a good amount of hash rate.
