Motherbpards with full 16X - 16X SLI

[a_Jhawk]

are there any motherboards with full 16X - 16X support for SLI. and is there a hugh differance between 8x - 8x SLI

Currently the only chipset which supports 2 x 16 lanes is the upcoming Nforce 590, but these have been held up by most manufacturers because the C19 chips have been found not to overclock well enough. The 590 with the C55 chips will apparently solve this problem.

The Intel 975x will only ever do 2 x 8 and the 965 with Crossfire support in the latest Catalyst drivers and a new BIOS will do 1 x 16 in one slot and 1 x 4 in the other.

Current data suggests that there will be little noteable difference between 2 x 8 and 2 x 16.

*WOOPS* I assumed he was talking about C2D. AS those below say, there are plenty of 2 x 16 boards for AMD.

16X SLI boards.

The bandwidth on 8x boards are good enuff. plenty of it.

AMD, socket 939

He didnt specify AMD why not give the guy some options?
a_Jhawk which socket are you looking for?

For AMD the aforementioned are good boards and for Core 2 and sli x16 theres the P5n32-Sli SE Deluxe thats full bandwidth PCIe.

Currently there is no performance gain between 8x and 16x.

 

[a_Jhawk]

im have socket 939. and is there really no performance gain between full 16x and 8x - 8x?

It's not quite fair to say there's NO performance gain, but we're talking circa half a percent here, if I remember correctly. It's not enough to justify it, and an 8x/8x will have more than enough bandwith for you.
