What is the point of most mATX SLI motherboards?

post #1 of 45
Thread Starter 
I must be missing something:

1. The mATX cases all have four PCI-E slots.

2. Modern-day cards take up two slots.

3. These mATX boards support SLI but they leave a space between the two cards:

4. ?? The only mATX SLI motherboard that appears to make any sense in this department is this one:

Some people buy a M-ATX motherboard and a mid tower size case just because they are going to SLI or Crossfire. I know that I am looking at buying the GEN 3 Maximus IV Gene. I just do not need more than 3 PCI-E slots. I am using one slot right now and I have a Classified.

I'm running SLI on a m-ATX board.
I bought it because the board was insanely cheap while still being capable of getting my i3 to 5+GHz for benches. smile.gif

Plus, it means if I upgrade this PC I can get a m-ATX case and make a nice HTPC out of my i3, board and RAM.

Edit: It's not SLI certified but the principle is the same, the SLI m-ATX boards are as capable as the bigger boards in some cases so why not go for a smaller size to allow for some flexibility in the future?

Edit2: I could be wrong but I think some of those boards are only crossfire certified, just in case you were thinking of buying one for SLI.

Some micro ATX cases have an extra expansion slot bracket below the four that the specification defines, so that dual slot video cards in the very bottom slot will able to be installed. Here's an example:

Dude, that's insane. Not gonna lie though, I am a bit jelly.

Some of you are missing the point. OP is wondering why board makers are putting the second x16 PCIe slot in the fourth position instead of the third, because in the former case you'd need an extra slot (for five total) on your chassis to accommodate a second dual-slot card.

I agree it doesn't make a lot of sense, given the small number of 5-slot MATX cases on the market. Ideally, it'd be nice to see MATX boards with three or four PCIe x16 slots so people can choose how to set it up. Not really an option for chipsets that only allow dual x16 or x8 for graphics though.

personally I don't like to buy bigger boards if i don't need it. just a personal taste thing. smaller boards actually gives me more options when it comes to case selection. if I ever decide to go mATX I can with a smaller board.

PCIe x16 is not just for GPU's. some of the higher end RAID cards and server based network cards also use PCIe slot. so that maybe a reason why they would put another PCIe when it doesn't seem to make logical sense. alot of TV cards also use PCIe these days so...

Im with ya Matrices its pretty dumb. It makes no sense to me why you would bother making an SLI mATX board, but force users to go without SLI or use an ATX case, especially when comparable (and usually better) ATX boards can be had for cheaper.

Max Gene-Z FTW!
