That is the problem, there isn't a TOLUD option in your board's UEFI, or most if not all boards of this type.
You lost me on this: "The bios only allows for dynamic, 2.5, or 3.5".
What option is that, in the BIOS?
If you haven't tried Dynamic yet, try it. Dynamic usually means the amount of space is adjusted to allow what is required to work correctly, providing more when necessary.
Changing TOLUD to a lower value in theory allows for a larger PEG memory space. But if you read that document, you'll see we may not really have control over how much memory will be given to the PEG memory space.

I have it set to 3.5 at the moment, and it's working with 5 cards. I'm not quite sure how as that is over 16G of RAM ... I think my memory screenshot makes more sense now. The standby memory is over 11G ram so 2.5 x 4 - and no idea on the other card. I'm also not quite sure why my resource monitor for memory looks more like yours now - https://www.dropbox.com/s/3mfb1nkn88sdu18/Screenshot%202016-09-17%2000.04.45.png?dl=0. Almost 12G free. If I set it to dynamic, then Windows will recognize all the cards, up to 6 - but will not allocate resources. So how can I set TOLUD, if I can't do so in the BIOS? I noticed this TOLUD setting wasn't even mentioned or in the screenshots for book that came with the motherboard. I guess I'll stick with 5, and start researching a board correctly about PCIE lanes before I go on any buying sprees. Thanks again for all the help. |
