Exclamation 8800GT compatibility with PCIe 1.0 and 1.0a

I've seen reports of older motherboards not supporting the 8800GT due to the older PCIe 1.0 or 1.0a.
Has anyone had any experience with that?

If you have an older motherboard and it does work, could you please post your mobo model/chipset/processor socket info?
Thanks!

They do not work on 1.0 or 1.0a so just upgrade your motherboard.

Default She works!

Alrighty, just got my 8800GT Superclocked from EVGA and it works fine on my old mobo.
I just ran 3dMark05 and played a bit of Witcher on max settings, smooth as warm butter.
I'm very happy, cause I was already crapping my pants worrying that my new purchase won't be of any use...

My specs:
MSI Neo4 K8N Platinum, nForce4 chipset//AMD FX-57//EVGA 8800GT Superclocked//Corsair DDR400 512MBx2.

Default should work

what I've heard (confirmed from multiple sites) is that PCIe 2.0 is reverse compatible to 1.0. there may be other problems with really old chipsets however causing the card to not work. but it shouldn't be the PCIe's fault.

hey everyone :)

we're having exactly the same problem..having an pci express 1.0a mainboard and wanting to buy an 8800gt graphics card.

our researches so far show that the right bios makes it work on the older mainboards and evga even made an update extra to fix those problems. we're not sure however if this makes the card work on ALL mainboards (in our case it's an epox 9npa+ sli we're worried about, although evga answered my question if it works on this mainboard with yes, but we need the bios update).

SyrousPL and leninvaros..you two contradict each other there a bit ;) maybe you two have different bios on the cards? i'm not sure right now, but aren't your mainboards exactly the same when it comes to if it should work or not?

regards,
dennis

PCI-E by it's very nature is backward compatible on a hardware level. Problems you may experience are (almost for sure) entirely due to bad implementation on the card makers part. There's just no reason in the PCI-E specs for cards not to work with early implementations (assumption: your mobo maker implemented totally standard PCI-E specs at rev 1.0 onwards)

assuming it should work theoretically...can the bios of either the card or the mobo cause it to not work? i think i read something in the direction that the card doesn't recognize the 1.0a pci express slot or something like that...but i could be wrong as well of course...

Hi, I also want to buy an 8800GT but I can't find information on whether my motherboard supports this video card.

My motherboard is an MSI K8NGM2-FID and I think it is PCI-Ex16 version 1.0a. What I did find out however was that Leadtek carries an 8800GT and in the reviews from newegg.com a guy said that it ran on a motherboard with PCI-Ex16 version 1.0a.

The chip on my motherboard is nforce 430 I think thats based on an nforce 4. Does anyone know if it'll work with my motherboard?

Thanks.

8800GT will not work on boards with the Via PT880 chipset. (many ASRock mobos) You can mod the bios on the card to make it work but........I think it is MUCH easier to buy a modern mobo.
