So will the 9800gtx be backwards compatible regarding PCI-E 1.1/1.0 ?

[Reality|Bites]

It doesn't mention PCI-E 1.0 though, Which might be a limit of 8X, So PCI-E 1.1 might be 16X and up.

Yer pci-e 1.0 can run upto speeds of 16x so its not that.
Its going to be hard to find out what motherboards have what connector.

Anyone know what the PCI Express version is on the Gigabyte P35C-DS3R is? It only has one slot, that's why I'm asking.

Cheers,

The first range of PCI-E motherboards only had 8X slots then the Nforce 4 chipset gave us 16X slots.

 

[jaykay]

But pci-e 1.0 can still run at 16x. Which still doesnt give us any help over what motherboards use.

Im guessing all p35 boards have pcie 1.1 as it was rumoured to have pcie 2.0

 

[Mr Paul]

I wonder if the nForce 4 has 1.1?

 

[Mr Paul]

Well the following may help

Says there the nForce 4 is PCIe 1.0a........

P35 chipset supports 1.1.

As said, the speeds don't tell us which version they are, as 1.0 can go up to 16x the same as 1.1a does.

 

[stickroad]

PCI-Express 3.0 is where its at.

So no nForce4 board will be able to use a PCIE2.0 card? Or could the manufacturers have used another chip on the board to provide PCIE1.1?

As far as I know, the PCI express bus connects directly to the northbridge so if the chipset doesn't support it, it most likely means the board won't. But I'm not 100%

i cant find if the nforce 650i supports it (p5ne sli). its so hard to find a list on the net which simply details the pci express formats on the boards.

 

[Things change I've changed]

this is absolutely ******* ******** for a fact, I have a badaxe 1 (975x chipset) and was going to buy a badaxe 2 for the higher fsb and even that does'nt have pci-e 1.1 ARGHHHHHHHHHHHHHHHHHHHHHHHHHH ffs, so why if pci-e 1.0 can run @ 16x the same as pci-e 1.1 why on earth can it not work with the 9800gtx ?

 

[Mr Paul]

Ah, because 1.1 has extra va va voooooom

According to this:

http://www.pcisig.com/developers/compliance_program/integrators_list/pcie/

The northbridge (C55) on the P5N-E SLI does indeed support PCI-E 1.1

 

[robg1701]

My Abit IP35 Pro has a bios option for selecting between PCIE 1.0 and 1.0a....hmmmm....

 

[Sinny]

So.

965p is supported by pci-e 1.1
975x isnt supported by pci-e 1.1
p35 is supported by pci-e 1.1

If thats right, my GA_965p_DQ6 rev 3.3 should support pci-e 1.1, correct me if im mistaken.

ah thanks a lot mate, puts my mind at ease

Whats the bet the GFX card manefaturers release a PCIE 1.0 version of the GTX... if there's money to be made it will probably happen.
