I did try a 5700xt, worked pretty well.
That’s good to hear
Maybe of interest here: in my response to FW13 AMD 7040 BIOS ReBAR support
I noticed that my 12th gen Framework now reserves 64 GiB for 3 of the 4 TB/PCIe ports. And the TB3 Alpine Ridge Controller in my Razer Core X gets actually assigned the full 64 GiB if attached directly (for a Goshen Ridge TB4 hub every downstream port gets a third curiously).
I sadly only have an old GPU in my Core X that does not support ReBar. So I cannot test anything else easily.
I am not 100% sure what affected this change, because at the time of my last screenshot here I am quite sure that it was only the ~450 MiB per port I showed there. I am running Windows 11 24H2 and the new drivers from the currently beta 13th&12th gen driver package. So probably one or the other allowed this.
The system may now be more ready for ReBar to actually work.
Although, like I said, the top left port is excluded from that and only gets the previous amount address space for some reason (Intel specs say 42 Bit addressing for the PCIe complex, 39 Bit addressing for physical memory, so at least 512GiB. No reason why it should run out of memory on 32 GiB RAM and 3x 64 GiB of USB4-PCIe reserved…)
