One of the goals that changed as I've been rebuilding my workstation was to trade up from P67 to Z68, in order to make use of my 2500k's IGPU. I was able to get the board in last week, and yesterday began testing.
Currently, I have one monitor hooked up to my primary (top) HD6950 2GB, and two monitors hooked up to the IGPU, over DVI and HDMI. I have installed Lucid's Virtu software, and have enable the IGPU in the UEFI. I have verified:
-All three monitors are accessable through Window's Change Resolution panel, and are configurable
-Crossfire with the second HD6950 2GB is active, and both GPUs are tasked when a game or Furmark is loaded
-Through Cyberlink's Mediaexpresso that the IGPU's transcode engine is available, and does produce improved processing times
What has me curious:
-When I tried running Furmark off of the IGPU by moving the rendering window to a monitor that is connected through the IGPU, I found that it was still rendering from the Crossfire team; what I believe is happening is that the monitors attached to the IGPU are being rendered from the primary HD6950 2GB and the framebuffer is being copied across
What I still need to test:
-That I can get two DVI monitors plus one Displayport monitor on the discrete HD6950 2GB, while having one HDMI and one DVI monitor on the IGPU
-That both Crossfire and the IGPUs transcoding engine are still functional with the above arrangement
-In relation to apparent framebuffer copying, I'd like to find out if I can get the IGPU to render independantly to it's attached displays, freeing the Crossfire team to work only on the three displays attached to the primary HD6590 2GB
-What perfromance and functionality differences there are, if any, between having the IGPU render independently or just perform a framebuffer copy from the discrete GPU team
If anyone has any questions, would like me to test anything specific, or has any suggestions, please let me know!
