Will PCI Express 2 VGA cards run on PCI Express 1 only boards ????

My MoBo only has a PCI Express-1 slot..

ya i think it can run..

thanx matter solved... it seems that all the new cards are backward compatible with PCIe 1.x..but may not work properly with PCIe 1.0 or 1a.. (Except for cards specifically designed for both the PCIe 1 & 2s..ex- Gigabyte 9600GT PCIe1 card & Asus 9600GT HDTI VGA)

My board is PCIe 1a.. so.... fingers crossed for the Asus HDTI card I'm gonna buy...

tell u if it works or not by Thursday

Check in the bloody asus site first and see if that card supports pci express 1 or not before buying the damn card.
Or is it that you're rich enough that you dont have to worry about it ?

It works..

heres the official version----------

Forward compatibility: old motherboard, new card

PCIe 2.0 is intended to be 100% forward compatible. Any PCIe 2.0 card should work in any PCIe 1.x motherboard. Again the link speed will be limited by the slower part, and will have to clock down to the slower PCIe 1.x speed. Because the card expects to have more bandwidth available, this could cause a loss of performance (as of this writing that loss is purely theoretical, as no commercial cards can saturate a x16 PCIe 1.x link).

There are scattered anecdotal reports of some very early PCIe motherboards, boards that implemented the PCIe 1.0a spec, not playing nice with new PCIe 2.0 cards. Again, this comes down to a violation of the specification on the part of either the motherboard or card. If you are stung by such a problem, contact the companies that made your motherboard and video card.
---------------

My MoBo is a Intel Pentium D series one...so I dont think Intel violates specs nor Asus violates specs...so fingers crossed..As I cant find any info in Asus nor Intel sites about this

 

[kosandpol]

Why are you wasting money on card that you know that you cant use on its full performance ?
Buy a PCIe 1 card or save the money and upgrade the mobo and vga card at a later date.

Problem solved.. I bought the Asus GeForce 9600GT yesterday & its working flawlessly in PCIe 1.0a..

Very impressed with the card

 

[kanishkaprr]

all the pci express 2.0 s are backward copatable with 1.0

 

[earthling]

yeah..i know that... my card is working without any trouble now..
