Strange Iray behavior using CPU

So I don't have an Nvida card and I don't expect to be coming into one anytime soon. In the mean time I have a two 4 core Intel Xeon's with 64GB RAM, two ATI 5770's 1GB DDR5 each. I'm runing Three Samsung LCD running left to right 27" Landscape, 29" Portrait, 27" Landscape,  Displays 1&3 are connected DVI to the 1st VGA, Dsplay 2 is on the bottom VGA, and my render output window happes on the 3rd display

I set up a scene, I go to render, the render begins and stays at 0%, the render window looks like the translucent "checkerboard" pattern of an Alpha channel, but nothing is written to the image. I can let this run for 1 minute or 30 it will never draw anything on the screen, my CPU at this point is at about 12%. If I cancel the render from the render dialog box, not the progress box, which can take several minutes and then click resume it will kick the CPU up to 100%, then after a few seconds I will get a message on the progress windows about something being written to the canvas and the scene will begin to render.

Is this a bug, feature, something else?

    Feature? I'd love to see marketing try to put a positive spin on that one, lollaugh. But that is weird, I've never seen it before.

    It would be interesting to see what the log file says. Help>Troubleshooting>View Log File...

    Been a while, I totally forgot the log file. Time to reset it and see what it says.

    What are the exact model Xeon CPUs you are running?
    Could be something strange happening with your CPU or RAM?

    It's a "cheese-grater" Mac Pro running Win 7 off a Samsung 870 EVO SSD. Two (2) 64-bit 45-nm Xeon E5620 (Westmere)

    The CPU essentially idling the first attempt doesn't make me suspect RAM, but the RAM is Crucial 1066MHz 8x8GB
    Granted the renders are fairy large, the last one was kicking upwards of 25GB once they get rolling.

    Here's something to try... if you are comfortable taking apart your computer.
    Take out your second CPU and RAM (Populate the ram into the primary CPU slots if any are empty) and try rendering again. 
    Primary CPU should be labeled CPU0, and seccond CPU should be CPU1

    I had to Google that to figure out what you were talking about, lol. I loved that design - it's probably my favorite computer case ever. I'm not a Mac guy at all, but I feel like I should buy one of those because it really is a work of art, inside and out. I'm fond of the Mac mini as well. The trash can Mac ... eh.

    The logic board architecture on this model mac does not allow you to take out either CPU and remain operational, All the RAM slots are populated. I'll wait for the official 4.11 and do a clean install. Hopefully the Postgre message goes away too.
