To start this off I have been having issues with my trifire triple monitor setup. Anytime I enable eyefinty running crossfire/trifire I will eventually get image frozen on screen and sometimes a sound loop while gaming. Amd states it is because I am running the 3rd card @ 8x speeds. I have removed one of the cards to test what they are saying and I get the same results running 2 cards crossfire at gen 2 or gen 3. So AMD is basically blaming this on the rampage IV. I would like to get some input on the issue from asus.

Anyways here is the response I got from AMD:

Response and Service Request History:

Regarding I get last image frozen on the screen with sometimes a looping sound/buzzing. System is unresponsive and requires powering off the PC. No blue screen and only error I get are on a reboot about power down the system in event viewer.
Single card + Eyefinity is fine. Crossfire + Eyefinity in 2x or 3x crossfire results in a freeze. Crossfire 2x,3x on a single monitor is fine.
I have tested each card individually all run single screen and eyefinity. MB: Asus Rampage 4 Extreme

Here is what the motherboard manufacturer states about the PCI-e slots.
http://www.asus.com/Motherboards/Intel_Socket_2011/Rampage_IV_Extreme#specifications
*
Expansion Slots
***** 4 x PCIe 3.0/2.0 x16 (x16; x16/x16; x16/x8/x16 and x16/x8/x8/x8, red) *1
***** 1 x PCIe 3.0/2.0 x16 (x8 mode, gray) *1
***** 1 x PCIe 2.0 x1
*
Note
******* *1-1 This motherboard is ready to support PCIe 3.0 SPEC. Functions will be available when using PCIe 3.0-compliant devices. Please refer to www.asus.com for updated details.
*1-2 For PCIe 3.0 x16 (X8 mode), PCIEx8_2B(Grey) shares bandwidth with PCIEx8_2A(Red).
*
It's difficult to get performance /functions with the above motherboard, so unfortunately we cannot offer a complete fix at this time. For both crossfire and the additional card, AMD offers very limited support since it is such a unique situation with special conditions, we have to make some significant adjustments and accommodations to offer any sort of support.
*
To use crossfire with “best” performance both PCI-Express slots need to be PCI-E x16 version 2.0 or better.
In the case when two cards are installed the system works with two cards at PCI-E x16 and x8 (means loss of performance, etc)
*
Then another card is added in a PCI-E x8 slot, which now brings the system to work at a X8 level and other issues arise
This is not a supported option as the features, performance, functions are all curtailed.
*
The slots here are mechanically PCI-Express x16, but functionally they are X16 and x8 slots.
*
To get “good performance” with a crossfire setup, we recommend using a motherboard with all PCI-e x16 slots ver 2.0 or higher slots, where all slots work or function at PCI-E X16 at every level.
Thank you.
