  1. Well 2.1 is really just. 2.0, so it can work? I'm sure that it will but you might get some issue with performance. Not the best person on different types of Bus though.
  2. it will work, each and every version of pci-e is backwards compatible.
    2.1 is just 2.0 with some of the management systems meant for pci-e 3.0. in other words its a go between.
  3. Simple Answer YES

    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.
  5. WHATS 18
  6. many people has been reported that 2.1 cards are SOMETIMES work on 1.0 slot and sometimes not...
  7. If you are referring to the "18" that appears at the end of every post, then it seems to be a glitch with the forum.
