Can a pcie 2.1 card run on a pcie 1.0x16 motherboard. I have a Asus p5sd2-vm .I have been reading that pcie 2.1 cards dont work on pcie 1.0 x16 slot. I AM an amd fan but all amd cards are pcie 2.1 .Should i go for NVIDIA cause all of its cards are pcie 2.0
There have been compatibilty issues with inserting a PCI-e 2.1 card into a PCI-e 1.x slot. However, those issues seem to be in the minority. I believe it has to do with how PCI-e 1.x was implemented on specific motherboard models.
