Hey everyone and thanks for any tips/advice in advance!

I have a Gigabyte GA-H55M-UD2H mobo with a PNY GTS 250 1gb and I want to buy myself another GTS 250 to bridge and run SLI. My two questions are does my mobo support nvidia SLI or ONLY crossfire? The website only mentions crossfire and the box only has the crossfire support logo and if it does support SLI regardless it doesn't mention it, can I even put a second video in the second PCI Express x16 slot? If i'm reading correct the mobo specs read as:

Expansion Slots
*1 x PCI Express x16 slot, running at x16 (PCIEX16) (Note 5) (The PCIEX16 slot conforms to PCI Express 2.0 standard.)
*1 x PCI Express x16 slot, running at x4 (PCIEX4) (Note 6)
2 x PCI slots


will the second PCI Express x16 slot not be suitable for the second card because it's only running at x4?

Unfortunately, that board supports Crossfire. Crossfire and SLI are not interchangeable.

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Hey dc3,

Thanks for the reply looks like I'll have to wait until my next mobo/cpu upgrade. No big deal. :thumbsup:

Just as anotehr quick question, if I was to get two ATI cards, could I crossfire well with this mobo with the second PCI express slot being x4?

It will work surprisingly well. I cannot remember the site, but I was reading the results of tests using high end video cards in PCIE-2 slots from X16 all the way to X4 (X16 length though) and the perfomance hit was surprisingly small through X4.

Crossfire at x16/x4 should be fine unless you are an enthusiast and care about getting that extra frame per second.
I think the chipset has a lot to do with crossfire/sli performance. Just make sure you get a good one.

I have two GeForce 9800 GTX's in SLI. The GTS 250 is basically a rebranded 9800 GTX. A 250 GTS in SLI is very similar to a single Radeon 5850 or 5870, or a GTX 470 or 480 if you want Nvidia, in terms of raw computational power. Be careful in changing out the motherboard and getting another GTS 250 as the cost of doing that might equal the cost of a single high-end card. There are instances where a single powerful card is better than SLI or Crossfire.

Thanks for all the advice guys!

I was working today and discussing this whole situation with someone at work who's been building computers a lot longer than I have, he's got at least 10 years on me.

I told him about the strange situation that my motherboard only supports crossfire and not SLI and he was honestly surprised. He said that it should support both, even though it only says Crossfire. He also said the same thing about the second slot only running at x4. I don't mean to say dc3 is wrong but with my friend and the fellow at Microcenter assuring me that it would be able to do SLI when I was ready to upgrade it seems I might have to stop in the store and see whats up. The whole reason I had bought this board was because I was told it could run SLI.

As for upgrading a whole new mobo and buy a new graphics card I would only do that if i was ready to upgrade my processor. My current motherboard doesn't support the i5 or i7 processors, that's what I mean by getting a new motherboard/cpu combo. :thumbsup:

It is extremely common for motherboards to support one but not the other.

It is highly common for motherboards to support either SLI or Crossfire. It is uncommon for a motherboard to support both, though, Intel's X58 motherboards do. I have heard of some graphics card makers experimenting with the idea of including a chip of the GPU's PCB that will allow for either if another card is installed. It is still in the experimental stage and nowhere near ready for production.

So I stopped by Microcenter today and explained my situation. They apologized for selling me a product after telling me it could do something it couldn't and the manager agreed on a return for the motherboard. Yay me! They helped me pick out a new mother board (Which I'll be picking up when I return the original). I've decided on a P7P55D-E PRO LGA 1156 P55 ATX Motherboard. What do you think?

It looks like a good motherboard to me.

Looks good, though, you could probably find a less expensive P55 motherboard if you looked. However, not many have both SLI and Crossfire.
