Will Z68 motherboards support 16x PCI lanes with SLI/crossfire ??

[chaparral]

Does anyone know if the new z68 motherboards with support PCI 16x with dual GPU cards in SLI or crossfire ???

Only if they have the NVidia NF200 chipset like in the P67A-UD7.

The Sandy Bridge CPU's physically don't have enough PCI-E lanes for 16x/16x, the Nvidia chipset splits the 16 lanes it does have into 32 (or some other form of witchcraft).

As far as I'm aware the main advantage of Z68 will be overclocking whilst using the onboard GPU.

It also uses the onboard GPU for video acceleration and also SSD caching.

doesn't the chipset determine the number of lanes and not the CPU?

Not on Intel chips, the PCIe controller is in the CPU since the first i5s

the Z68 boards will have PCIe V3 lanes, which are twice as fast as the PCIe V2 on the P67 boards i believe. so x8/x8 on Z68 boards will be the equivalent of x16/x16 on the P67 boards

I thought PCIe 3.0 was coming in the generation after z68? With ivy bridge?

It is, as already stated the motherboard has nothing to do with how many PCIe lanes there are or which generation of PCIe it is.

To quote the answer i got when i asked the same questions

The Z68 seems fitting someone who wishes to overclock and use igpu

P67 who wishes to overclock and use graphics cards

H67 for those wishes to use neither overclocking or graphics cards and just run decent low cost machine.

even if the z68 had pcie3.0 slots its wouldnt make a difference if the CPU doesnt support it, and untill ivybridge, it wont.

 

[nightmare99]

and untill sandybridge, it wont

That should be Sandybridge-E right?

sorry meany to write ivybridge, but sandybridge-E aswell. Thanks for the correction
