LGA1151 PCI allocation limited to 64GB

Hi. I have a MSI H310M PRO-VHD Mainboard with a i5-8500 and 8GB RAM which works fine with a single NVIDIA Tesla P40 under Ubuntu 22.04 but doesn't POST with 2 or 3 P40. There are some forum posts where someone wrote to the MSI support and they said that they never testet P40 on that mainboard. Is there a chance to get more than one GPU running by BIOS patching? Is this actually a BAR issue?
