ivanov Posted June 30, 2014 Posted June 30, 2014 (edited) I tried running 3 and 4 cards but always only 2-way CrossFire gets enabled I used Rampage IV Black, Rampage III Black and P5E3 Premium (on this only 3-way), so it is rather not MB related. OS Win7 X64. I tried newest and oldest drivers that support 2900 XT. Are there any special drivers required for 3-way and 4-way? It is quite hard to find anything about 3-way and 4-way (even no validations at HWB!) but I have seen that during presentations such configurations were used - example.

Stelaras Posted July 1, 2014 Posted July 1, 2014 Ati 2900 only supported up to 2-way CF. You can't run 3-way or 4-way . That's why you can't find any benches . Quote
Massman Posted July 1, 2014 Posted July 1, 2014 but I have seen that during presentations such configurations were used - example. Then again those presentations also said Phenom would be awesome :battle: Quote

ivanov Posted July 1, 2014 Author Posted July 1, 2014 Huh, then it is quite weird that 2900 XT has two CrossFire fingers, it clearly implicates that it should run 3 and 4 way Xtreme Addict suggested that there are some special drivers that AMD used for presentation of 3-way. Quote
Administrators websmile Posted July 1, 2014 Administrators Posted July 1, 2014 1950 Pro has two cf fingers as well, and 3way cf doesn´t work - so this is no indicator Quote
