No SLi on newer S1156 boards?

Looking at the web pages about the new i5 and i3, Intel also listed 3 new chipsets that seems to no longer offer 2x8 PCIe support: http://hothardware.com/Articles/Intel-Clarkdale-Core-i5-Desktop-Processor-Debuts/?page=4

Q57, H55, and H57 looks like they are 1x16 only, while the current P55 can do either 1x16 or 2x8, which implies to me that dual video card won't be supported on newer board without extra hardware similar to that Gigabyte P55 board that claims to do 2x16 PCIe

The limitation could be related to having support for the new graphic chip on new i5 CPUs

If you want to run SLI...why look at the new chipsets? The purpose of the new chipsets is to support the integrated GPU in Clarkdale CPUs...if you plan to get Clarkdale and SLI...P55 would be the logical choice.

I know this doesn't answer your question, but...

ive found a board with that socket that supports SLI......

I already got a P55 board. I was just wondering if the new chipset is simply not able to SLi or Crossfire as the new chipcet is supposed to be able to support the integrated graphic chip, where P55 doesn't.

I've decided to get i5 750 for sure. Quad physical core still outperformed the new Clarksdale CPU (dual core with hyperthreading) by a good margin. I'm quite sure that 750 overclocked to 4GHz can still beat any i5 6** or i3's clocked to 5GHz in any cpu intensive tasks. I'd rather get something that can make 3Dmark look good, not just the raw GHz's. Getting my user name changed to 6GHz_or_bust instead of 5GHz would have to wait a few more years.

That wasn't his question

If you already own a P55 board, and you're planning to get an i5 750...then your question makes even less sense. There is absolutely zero reason for you to consider a board based on H55 or H57

Unless your simply asking out of curiosity...

I'm not trying to dodge the question...I just don't know the answer, and apparently, nobody else does either

I was just curious. I was looking at the new Clarksdale when I noticed the newer chipset has onboard video for I5 on CPU graphic, and all were 1x16 PCIe, no 2xanything at all. That lead me to suspect the newer chipcset didn't support or allow Crossfire or SLi since it could conflict with the on chip GPU.

This one supports dual x8 slots...but does not specify support for SLI or Crossfire...none of them do, so I think you're probably right. Weird though, seems to me it should be possible, even if it doesn't make any logical sense

Uh...new Asus H57 board supports CrossFire and SLI
