Hello,
I recently bought a biostar racing z170 gt7 motherboard off of newegg for around $80, which I think is a steal. Since I am about to buy a graphics card for my new system, I have a question. Can this motherboard run sli? I know the specifications says it only supports crossfire, however many people said that the only requirement for sli was the ability for the pcie slots to run at 8x/8x speed. On my motherboard manual, it says that the motherboard can run 2 pcie slots at 8x/8x speeds. Below is a picture from the manual.

Can anyone tell me if this motherboard can support sli? The information could help me decide between radeon and nvidia.
Thanks in advance to anybody who replies.

No. Sli is where a chipset allows for both nvidia cards to run in tandem but share the ram limits of the card. Nvidia algorithms, programming, card pin designs etc are what allows for this. With a crossfire only board, the chipset doesn't recognize the sli configuration,only the crossfire configuration. You can run sli/crossfire at x16/x4 or x8/x8, that's the pcie bandwidth. For low grade cards, x16/x4 is fine, they don't have the ability to soak up x4 bandwidth so both cards work at limits. With top line power cards that can soak up x4 bandwidth it would suck as the x4 would get maxed out and lower performance of the second card, dragging everything down. So x8/x8 is preferable. X8/x8 is not a sli requirement.
You have a crossfire...

You have a crossfire only mobo. You are stuck with Amd cards for 2x, can use an nvidia card solo, but no sli support.

Seems Biostar has finally come out of the dark ages and built a decent board. Normally I'd not touch Biostar with a 10' pole, but this looks to be an exception. Thanks for the link.
