Can my motherboard fit a dual-width video card?

post #1 of 9
Thread Starter 
I was looking at buying a new video card (probably a GTX 570) and I noticed some of them have a requirement saying "dual-width PCI Express slot", but I don't know if my motherboard would work or has enough room. I have an Asrock K10N78:

My current video card is a HIS Radeon 4850 http://www.hisdigital.com/un/product2-385.shtml

When I look inside my case it doesn't appear that the new card would be blocked by anything, but I don't know for sure. Can anyone help me please?

I'm not exactly sure, but I think that just means because its so large, it takes up 2 slots, so yeah, it will just fit. The cards are usually designed to sit above everything.

Yes it will fit as long as you don't have anything installed in the closest short PCIe slot. Since it is a 2 slot card it will cover that first short PCIe slot.

EDIT: What type of case are you using? Small cases can have issues with the length of the card as well but usually you will be fine.

From the information provide by you, I would say you are ready for a new GTX570 or any other dual-slot card. When a dual slot card is installed in the primary (green) PCIe slot, it will look like the pic below.

Your current card is likely sitting in the green slot with nothing in the next PCIex1(white short slot) next to it. Your current card (even though it only has 1 PCI slot cover) occupies 2 slot width because it has a pretty big heatsink.

And 1 more thing for you to check: make sure your Power Supply has 2 PCIe connectors. Your current card uses 1 but you will need 2 for a GTX570 or alike.

Do you have any other cards in your slots?

It just states that the card takes two slots worth of space on your case backplane.

If your case is crammed to the brim you might have to remove the card in the PCI/PCIe slot closest to the main PCIe 16x slot, as it will collide with the cooling mechanism on the graphics card.

Thanks for all the help. I actually just realized both my current card and the GTX 570 are 4 cm thick, also I don't have anything installed in those little slots so I should be fine.

I'm not sure what the case is since I got it from my friend, but there's a little over 12 inches before a video card would hit something.

One more question. On Tom's Hardware someone told me:
Quote:
The Asrock K10N78 is NOT a 'real' SLI MOBO. You can use any PCIe GPU, but a GTX 570 is 100% guaranteed to bottleneck with the NVIDIA GeForce 8200 Chipset. I would either get a new MOBO, maybe CPU if it's NOT a Phenom II, or go with a GT 430 or at max the GTX 460 {even the GTX 460 will be bottlenecked}.

Is that true? My CPU is a Phenom II X4 955. I know my motherboard isn't SLI, but how would that affect performance since the GTX 570 only plugs in to one slot?

Uh.... I don't understand how that makes any sense, unless they are talking about Hybrid SLI.
