Yep. Same here. Gary from Asus and XFX are looking into my Tri-Fire problem. My 5970 + 5870 are not working together (Tri-Fire), but they work perfectly fine when alone (or just leaving them in place and only closing the other card PCIe switch). They think it's a motherboard BIOS problem.
With my 5970 in PCIe slot 1 and 5870 in the PCIe slot 3, they are both recognized, but only the 5970 goes in 3D, and the 5870 is ''stuck'' in 2D with 0% activity both in GPU-Z and AMD overdrive when playing games or doing Furmark in Multi-GPU. I can game for hours without a single crash. But the 5870 stays in 2D.
People with this board and 2 graphic cards should look at Furmark Multi-GPU with AMD Overdrive open to see if both cards are showing activity. If I haven't done so, I would never have found that the 5870 was always stuck in 2D in Tri-Fire.
But if I close the PCIe slot 1 switch, and boot with the 5870 in slot 3, then it works fine in 3D! Can boot in Win7, and play games, and 3D clocks are raising normally when playing.
I've read about others with SLI and Crossfire also having problems with this motherboard, just like us.
This is with a clean Win7 install, with Catalyst 11.1. I even tried Catalyst 10.11 and 10.12 to be sure. I also tried with a different PSU, with every possible combinations of rails possible. The 2 EZ-Plug are ''Plugged''.
The 5970+5870 set-up is working fine on my other system with Asus P6T.
5870 alone, ok. 5970 alone, ok. But not both.
But I can't believe the level of help Gary at Asus is giving me. They bought the exact same parts I have to try to reproduce the problem at Asus and find a solution! Wow!Edited by Levesque - 2/12/11 at 9:16am
