    Exclamation Rendering capped @ 12GB??

    I have a friend with a very stout computer he uses as a server and rendering. The basic specs are as follows:

    • Dual Xeon 5675's
    • 96GB RAM (6x16GB ECC)
    • 4x200GB SSD in RAID1
    • 2GB 560ti GFX.

    Now, I do have to say this computer is an absolute beast. My Core 2 Duo E8400 w/ 8GB RAM rendered a 300-frame walkthrough under "Best" settings, and it took about 32 hours to render. His computer did it in 6 hours. But here's my question in our observation of this computer while rendering: Even when the 24 CPU threads were all maxed out at 100%, RAM usage didn't go over 12GB? Is there a setting that can "uncap" this, or is this a Windows issue, or what? We figure that with a program like Revit, surely it's capable of seeing and utilizing this much RAM. Any ideas? Thanks!!

    As far as I know, there's no limit. Just because you have excess RAM doesn't mean the program will use it. And even if it does use it, that doesn't mean it'll make a performance difference. It might be that 12GB was perfect for a 300 frame rendering at that resolution. Maybe rendering at a higher resolution with more complex geometry would push it to 24gb? Either way, 6 hours for a 300 frame rendering is nothing to complain about!

    No kidding! I'd be happy just being able to send batch renderings to a machine like that, let alone use it regularly.
