Pci 2.1 on pci x16 mobo ?

hi guys .

with TH communities help , ive decided to buy the ati hd 6450 (ik its a low end entry level card) .

its jus for a bit of gaming and hd tv purpose.

and now a problem arises , while i ws lookin at forums about the card , i found that it had some compatability issues with mobos having PCi X16 (1.0 or 1.1)
since the HD 6450 ws released in 2011 it has PCI 2.1 support.


when i asked about the compatability issues on my mobo in a forum ,they said it will work fine .
bt yesterday i saw on some forums that the performance of the card will be buggy on a pci 1.0 board. :o


my choices for a card was hd 6450, hd 5450 and gt 520,
when i asked TH community,
they said to go for the hd 6450 ...

also should i go for the gt 520 ?

will it work well ??
is it gonna be buggy, (like crashing and stuff) ?


my mobo

  1. If its been reported to work on your board you are fine. Pcie 2.1 cards should work in a 1.0 slot. The "buggy"reports are from people on some boards who did not update their bios to handle the new spec

    hmm , i've updated my bios , the problem is that the latest biostar bios update for my mobo ws dated (2010-02-01) .. that ws the last bios update for it

    is there any other way to make it up to date .

    since its a 2010 based bios , can it support the 2.1 version ??

    and ty 4 ur answer .

  4. It should, all PCI-E generations are backwards compatible for the most part. The best way to know is to test it.

    2.1 cards were out in 2009. I'd expect a 2010 Bios to have any fix if needed, and it's a pretty low power card. I'd expect no issues.

    That being said the 5550 should be a much better card for gaming, and here's a 2.0 version for under 60.

    is there any way to find out whether the bios support 2.1 (without actually testing it) ??

    there is a huge problem here too , i cant buy from newegg, since im not from US :cry:

    newegg shoulda been made international :pfff:
  7. just try amazon
  8. Yes. Amazon if you can. Last thing I got from them that didn't work I just went to the order, clicked RMA, checked "it didn't work" and they sent me a UPS guy with a label. No charge. Painless.

    Might be different outside the US but still
  9. k .. just leave the buying process ..

    is there a way to check the pci 2.1 compatability of my mobo ????

    +1 its the card to go for unless you stumble across a hd 6450 gddr5 version..

    you could call/email biostar but you might call 3 times and get 3 different answers lol. it should work. But in very few cases with certain boards and certain cards it might not. Usually because of user error or bios updates stopped before pcie 2.1. Since 2.1 was 2009 and you had updates in 2010 it wouldn't worry me.
