6800GT PCIe running at 8x ??

I have a Leadtek 6800GT PCIe 16x, but looking at the nvidia settings it shows 8x instead of 16x.
What says yours?
Is this a missprint or does it really run that slow?
And, if so? how can change the speed of the PCIe slot from x8 back to x18?

Thanks

 

Check your BIOS, maybe the are set to be at that speed.

Try other Drivers.

 

Kain,

after looking at the bios settings I couldn't find where the PCIe speed is set and I decided to upgrade my Mobo Bios from 1003 to 1004 beta: wrong idea! I got a BSOD.

Windows was corrupted and also was norton antivirus.
I managed to recover windows but I'm having problems reinstalling norton. I'm using a different computer now.

Anyway, thanks for the advice I'll try it later.
BTW my drivers are 70.25, and I'm thinking in upgrading to 71.81

 

Have you sorted this 8X issue out yet Neo?

I'm getting the same thing.

 

check your SLI selector card on the motherboard, I know my asus came with it set to *dual* as default. If thats the case, switch it around, and u will get full 16x PCI-E!

 

Checked that before and it's set in non SLI mode.

 

yeah, not so sure about the DFI one, cos they are slightly different - have jumpers rather than a slot card right? But im pretty sure that will be the issue on NeoHuman's A8N.

 

Do you think it'll be much of a performance hit running it at 8X?

 

no, i dont think there will be a single bit of difference. AGP still runs at 8x remember!

 

Hi all,

Checked the SLI switch and it's in single card mode.
Haven't tried other drivers cause when I try to uninstall the old ones the computer hangs.

 

The questions are:

Is it really running at x8?

How can we mesure the speed of the PCIe port?

 

Sorry to bring up old threads, but i got the same prob, and cant figure out why. Is there any performance drop or is this strictly an aesthetic thing? I mean having x16 as opposed to x8.

 

You won't notice a difference. If any card takes up all the bandwidth of 8x, maybe the 7800gtx 512mb does, but I doubt it. What grahpics card do you have?

 

It will make bog all difference in the real world. It is probably more like as Mike has said that the board is running in what it thinks as SLI mode rather than single mode.

 

8x and 16x is totally irrelevant since the card cant fill even 8x, besides if it is the nv40 pcie 6800gt bridged from agp mode to pcie mode than its the gpu and bridge chip itself, but as i mentioned there is no performance diff since even the 8x agp isnt fully used and still it is slower than pcie 8x so no worries.

 

Ok thanks, i have a 6800gt, so if i wont get a performance increase, its not worth bothering with.
