• 2x PCI Express 2.0 x16 Motherboard Question
    6 replies, posted
I normally work with motherboards that only have one PCI Express 2.0 X16 slot, but I am planning on SLI soon. So to do that I need a new motherboard, and so far I have come across ones which say "Expansion slots: PCI Express 2.0 X16 - 2(x16, x4). My question is what does 2(x16, [B]x4[/B]) mean? Does the difference between x16 and x4 mean anything or is it a default for dual PCI Express 2.0 X16 motherboards?
x4/x8/x16 etc is, in a nutshell, the speed of the slot. If you plan on using SLI, the minimum you would want to go is a motherboard that is capable of x16/x4 single GPU [I]or[/I] x8/x8 dual GPU (IE it maximizes the performance when you are using one GPU, and stabilizes it when you add a card). x16/x16 is always nice, but after x8/x8 you stop seeing huge performance boosts. If you plan on doing SLI don't go for the x16/x4 motherboards, they are essentially designed for single GPU builds.
Thanks man. Do you have any good dual PCI Express 2.0 x16 motherboards to recommend me? (AMD AM3 DDR3 1333MHz) [editline]24th December 2011[/editline] How's this? [url]http://www.newegg.com/Product/Product.aspx?Item=N82E16813186198[/url]
I would spend a [I]little[/I] more cash than that, to at least get a reliable motherboard. I currently have [url=http://www.newegg.com/Product/Product.aspx?Item=N82E16813157281]this[/url] one, and it's pretty nice.
This is probably one of the best AM3 socket boards you can buy AND it has 2 pci-e x16 and 1 pci-e x4.

I appreciate the help. I'll probably go for that board after saving up a bit more.
I have the Gigabyte GA-990FX-UD3, [url]http://www.gigabyte.com/products/product-page.aspx?pid=3894#ov;[/url] its a great board and it does 16x/16x. I have 2 HD 6950's in it at the moment and it works great
