Going 8800 SLI ?

ok my 8800gt 512 arrived today and Ive placed it into the lower PCI-e slot and then joined the two cards together with the sli bridge.

When I boot my system tells me im now in sli mode.

Now heres the problem. According to my board both PCI-e slots are x16 yet when I use nvidia control panel to play with the settings it says that the second slot is x8 only !?

Any one have any ideas why this may be... or any other program I can use to test this ?
 
What motherboard do you have?

with the 8800GT SLI even with both slots running at x8 you wouldn't really notice any slowdown over 16x.
 
Yes, this is normal, and as Rroff says, you wont see it slow down ( Obviously ) you will see it go faster, but the card suddenly running at 8x is normal.... And irritating!

Is it worth getting a newer board with 2x16

NO!
 
would there be a significant increase by getting a board with dual x16 slots ?

Im not over kean to spend another £100 for a small increase !?
 
I'm sure there is someting between the slots on asus boards that you need to flip?

I think it's called an ez selector card.

Not worth £100 no... At least I dont think so, not for a pair of 8800GTs at least.

No, thats just to set whether you are using one or two cards.

Unless your running at 2560x resolution with ultra high details and the cards OC'd to the max (in which case your gonna be struggling with 512Mb VRAM anyhow) there is no performance decrease from 8x over 16x with these cards. The 280GTX or an OC'd 4870 is the slowest cards that will noticeably suffer at all from 8x instead of 16x.
