Will RC482-M754 mobo run a 8800GT?

  1. I have mobo RS482-M754 and I am wanting to buy a 8800GT
    but am scared as mobo is PCIe 1.0a...and the Video Card the PCIe 2.0 version?
    does anyone know if there will be issues with card or mobo?
    I have not installed mobo in case yet
    but have 2gb of ram 2satas (for Raid0) and really wanting someone to confirm that a 8800GT will run (so I don't have to go thru hastle of returning it)

    did u think I have to flash VC bios or anything to get video card to work
    do u think a 8800GT will just work no problem?

    It ought to work fine assuming your PSU can handle the extra load and you have a PCI-E x16 slot. PCI-E 2.0 is backward compatible and I can't see why you'd have to perform a BIOS update.

    tons of people having trouble with 8800GT and PCIe 1.0 or 1.0a

    just go to
    and look for:geforce 8 series
    Compatibility issue with PCI-E 1.0a

    thats why EVGA and others have released BIOS updates for this exact reason
    it doesn't fix all
    some mobos still don't work..
    so I am wanting to know if someone else has ran with my mobo

    oh sorry 8800gt has also problems with 1.1 PCIe as well

    I have tons of website forums that also talk about it
    but havn't used forum enough to post them yet
    I would just really hate to go thru trouble of buying a 8800GT
    just to return it...as many others have done so

    has anyone seen a list of PCIes incomptible with 8800GTs?

    I would LOVE to see that...I have heard VIAs chipsets are bad but even asus and ecs have also not been able to run 8800GTs
    I should just start my own

    8800GT I have looked for help from ECS but they are useless

    they told me to try it out...and send back iif it dont work
    (so ECS doesn't sound all that confident it will work)
    sounds like fun
    order in a 8800gt (wait for it to come in)
    spend time installing and debugging
    and then possibley send back and start again

    8800GT PCIe comptibility issues:

    look here:
    for :
    Compatibility issue with PCI-E 1.0a


    well and plenty of other forums...
    but what I need is a list of PCIe mobos that are not compliant with 2.0
    (as from what I gather its not really a Video Card problem, however they can get around it with a BIOS rev for it...like EVGA:
    now ATI amazingly enough takes the smarter way
    they default to 1.0 PCIe and then scan to see of they can raise to 2.0..
    I want a 8800GT !
    ok sorry I am ranting now

    As far as I know (though, I don't keep up with the interface standards as often as I used to so I very well may be wrong), according to PCI-SIG, the PCI-E 2.0 interface is backward compatible with PCI-E 1.0 and 1.0a. If manufacturers have failed at the hardware implementation of this, in my opinion, it doesn't reflect the industry standard's architectural design.

    Furthermore, according to the Wikipedia article you told me to look at, the issue is primarily isolated to VIA chipsets which the RS482-M754 doesn't have.

    mostly VIA chipsets incompatible with 8800GT

    but I have seen others chipsets supposidly incompatible in forums
    so I dunno...guess I am just looking for someone who has ran my mobo
    or 1 close with a 8800GT
    I know IN THEORY it will always work with older PCIe versions
    like 1.1 or 1.0a or 1.0...in theory
    but in reality
    MANY MOBOs will not run a 8800GT

    I could grab forums all day that talk about it
    and I know XFX and EVG I know for sure have made BIOS revs just for PCIe compatibility issues
    again the problem is really the BIOS? (or hardware) not sure of the MOBOs
    EVGA says...however if they haveBIOS patches to fix this...why do they not all come with that BIOS installed now?
    well I have even seen some 9600GT stories...now I am scared to buy NVIDIA..

    oh sorry didn't see your EDIT button
    won't happen again

    Well I guess you can speculate all day and fear the results that a small percentage of consumers have had, or, accept the fact that your card in "theory" (and probability) will work, with the realization that if it doesn't you can always return it.

    The odds of someone strolling through here with the exact same motherboard and video card are slim. It has the potential to be months or longer of you bumping and hoping.

    Either buy the card or don't :p.

    your probaly right Zenosincks..thanks man

    I have been gathering info from forums and trying to make an "8800GT PCIe incompatible list of MOBOs" that will not run the 8800GT..now I am trying to also sort thru and determine which ones have tried the newer BIOS rev and those that have not.. as supposidly it "Improves compatibility with certain PCIe Gen1 motherboards" as EVGA says
    I will clean up what I have and post here?
    and if anyone has had different results with a mobo either working or not I would luv to know
    thanks for your input Zenosincks...I am going to order a 8800GT today,
    will post back what happens
