Hey guys, I have a question as to the backwards compatibility of pci-express 2.0 with the older pci-express 1.0a specification. My motherboard which I got a few days ago has the older 1.0a spec. My motherboard is a Biostar P4M900-M4 ver.6.x with latest Bios from this September. Here is the website for that motherboard: http://www.biostar.com.tw/app/en-us/...t.php?S_ID=283
I would like to purchase (and install on this motherboard) either an 8800GT,8800 GTS from nvidia or 3850,3870 from ati, all four of which use the new pci-express 2.0 specification and require motherboards with pci-express 2.0.
I've heard so many conflicting reports, yes it is compatible, no they are not compatible etc.... Then I see some people whose older mobos with 1.0a specification worked with 2.0 video cards. AND I see some people whose older mobos with 1.0a did not work with an 8800GT. Can we just settle this issue with a simple yes/no or is the answer mobo specific, or is this just ultra complex?
Lastly, is it just a BIOS update that is needed to make these two specifications more compatible?
Thanks a bunch for your time guys.
