Area-51 AAT2250, PCIe expansion slots, CPU or PCH?
Hi, can one of the Area-51 AAT2250 PCIe x4 Expansion Slots run direct to CPU? Or are both slots forced through the PCH? I couldn't find a motherboard diagram depicting this.
Most 3rd Party motherboards let you configure this setting.
I also couldn't find out which ssd slots run direct to cpu.
Thank you

PCH.
While the PCIe x16 slot is Gen5 as supported by Arrow Lake processors, both of PCIe x4 slots on the AAT2250 board are Gen4. They are likely being connected to the Z890 chipset, which is supporting PCI Express Revision 4.0
