Having a hard time booting with >4 cards on S2600IP

Hello!

I've been mining with an S2600IP with both CPU sockets populated, and no matter what configuration of riser positions in the PCIe slots, I cannot boot with more than 4 GPUs.

I'm using GTX 1070s for this setup.

I can boot with 4GPUs using most PCIe arrangements, but the moment I try to put a 5th, it does not fully boot.

When I say it doesn't fully boot, it beeps like it's normally passed POST, but I get no video out from any card, and it never boots into windows.

Am I missing some sort of BIOS setting or something else I am overlooking to make this work?

I have updated everything on the motherboard to the most recent version, if that helps.

Thank you for any input you may have, and your time. :)

Thank you for your suggestion! I just checked the BIOS and that setting is already enabled. Drat. I have not tested the setup with it disabled though...
