im in the futile search of this information. its killing me inside, slowly and softly. from everything that ive learned, PCI-e2.0 is backwards compatible with 1.1, but 1.0a is a little more tricky. it only works with some cards.


From Wikipedia - "PCIe 2.0 is backward compatible with PCIe v1.x. Graphic cards and motherboards designed for v2.0 will be able to work with v1.1 and v1.0. In some cases it is possible that a PCI-E 2.0 card will not work correctly on a PCI-E 1.0a slot. This is only limited to certain video cards."

so this is what ive heard.


people have gotten these graphic cards working on a 1.0a PCI-e slot.

8800GT
HD 4650
HD 4870



if youve had any experience with putting 2.0 cards on a 1.0a slot, speak up! personally, im trying to find out if a HD 4670 will work on a PCI-e 1.0a, but im sure a collective list would be very helpful to others, not just me.



thanks in advance,

this is a great list to start, unfortunately I have a card that does NOT work with the pci-e 1.0a slot. Asus HD 5770 is a no go :(

I can confirm that the 8800GT's work on a PCIe 1.0a slot.

HIS HD 4850 also work for PCI-E 1.0 slot. (Gigabyte GA 965P-DS3)

Wouldnt this be a matter of specific motherboard support rather than the slot being the issue ?

Probably, but then again there might be certain cards that don't play as well as others regardless of mobo BIOS updates.

ya I guess that might clarify things a bit. In my case I have a ASROCK 939dual Sata2 mobo and I have tried the Asus 5770 and just today I tried the Sapphire 5750 and no dice on either of them. Thankfully I have a great store here that lets me return anything before a 7 day window is up :)

What chipset is that board using?

Confirm that twice, I used a 55nm 9800gt (not EE or green).

Very few cards have issue with board compatibility with a few exceptions. Those exceptions are that not all boards can supply 75w form the slot and Turbocache and Hypermemory doesn't work when ram is only installed in single channel mode.

That is pretty old and no longer around. It might work but with that dead brand there is no guarantee.

If you have that latest drivers (which are 2.20 I believe) then there is no more you can do with it I'm afraid.
