H55 Question

Can someone tell if you can do crossfire on the H55 chipset?

i've seen some very conflicting information saying that it is not possible due to the amount of lanes available and some say it is and some say it is if your not using one of the core cpu's with and IGP.

The MSI H55M-ED55, fro example, says that you can at 8x+8x.

also what is the difference between H55 and H57?

thanks
 
EDIT
AFAIK, you'll need a P55 chipset (you can still use the i3) to do 16x/16x CF/SLi. H55/57 chipsets can only provide max 16 lanes of PCI-e bandwith. So yeah, nearly all h55/57 mobos can do 8x/8x, as long as they have two slots

H57 is very similar essentially to H55, but H57 boards tend to be higher-end boards, with more features, and cost more.

sorry i got it now.

so regarlesss of which does the H55 support crossfire or si at x8+8x or would one slot be limited to x4?

I edited my first post, I was wrong.
You won't see a H55 board with more than two PCI-e slots, that chipset can only provide 16 lanes of PCIe for graphics use. Single slot card being GPU (usually low-power) that hence the name only slots into one PCIe slot. You'd be better off if you had h55 to get a GTX460 or some dual-slot card, and get full 16x PCIe lanes. Sorry, I am making sense?
 
Yeah i see what your saying, the info available about Intel chipsets seems to be laid out in a quite a complicated way compared to AMD.

So H55 will support two gpus at 8x8?

i was planning to get crossfire the hd5800 series, since that board is crossfire, but, just to be clear, your saying that they wont fit?

You can get H55 motherboards with more than 1 PCIe lane, you can get ones with more than 1 PCIe x16 lane, however so far as I can tell, and you are right, it isn't exactly clear, H55 does not support multiple video cards. H57, however seems to be the same as H55, but with support for SLI/Crossfire.

But with that said, there aren't a whole lot of H57 boards on sale, you won't be left with much choice. For the price you can get yourself a P55 board, which will be just as good and P55 support multiple graphics card setups
