Crossfire with PCI x1 to x16 adapter-- possible?

post #1 of 22
Thread Starter 
I have a single x16 pci motherboard with a 6850 and am currently considering going xfire prior to the Battlefield 3 release. How well would an xfire setup work with this http://www.newegg.com/Product/Product.aspx?Item=N82E16815158223&Tpk=pci%20express%20x16%20motherboard adapter?

That's if the xFire bridge would actually connect to the different leveled cards.

you dont actually need a bridge its just there to help. but still, i see what you mean i can see a high profile graphics card hanging off that adapter somethings gonna snap. headscratch.gif

I'd assume you still would only be able to pull x1 out of it, instead of x16.

I think it'd be like putting an x16 card into an x1 slot.

First, even if it did work your bandwidth would be very very limited... (40-50% performance)

Second what motherboard do you have? (Don't see in sig rig)

Crossfire With x16 / x1? I bet the results will be rather poor.

I would suggest against that an just buy a new motherboard, there are plenty of inexpensive motherboard that support crossfire. You're going to suffer some serious bottlenecking I'm pretty sure. Especially running crossfire. If it will even work at all because your board wouldn't have crossfire support.

AMD motherboards are wonderfully cheap. I highly recommend you just upgrade your motherboard. The hassle of figuring out how to safely mount your GPU on that riser won't be worth the performance gain. At x1 that's going to be horrible scaling and I doubt you can even crossfire them; how would you even connect the crossfire bridge? Even if you get past the crossfire bridge connection, I doubt crossfire would work in that setup.

$84 after rebate:

This is my MoBo:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813128451&Tpk=13-128-451

I'll be taking my rig apart to RMA my Gigabyte 6850 as it's been giving me some issues/fails miserably at slight over-clocking and I get awesome deals at a local stores for cheap cheap fans, PCI cards and anything pretty much. I hadn't really considered the x1-->x16 deal but I sort of stumbled upon that little PCI. It has me wondering since.

I bought the Motherboard less than a month ago.

P.S.
The 6850 is plenty for me at the moment, but after research I noticed how great the new cards scale.
