Best Motherboard for Crossfire

[Mac070]

I need a motherboard that will give Dual RX 480's the most potential . IM running an I5 LGA 1151 and water cooler. I dont care if i can OC the CPU or not. Under $120. Thanks

Edit: Not sure how good the overclocking is on this board but it will support CF RX 480's at x8,x8.

What motherboard do you currently have? If it has a x16,x4 PCIE slots it will work fine. Going from that to x8,x8 or x16,x16 is pretty minimal for CF (SLI requires a min of x8,x8). It's an older test but as you can see the difference is really minor.

If you do want the higher speed then you will want a Z170 MB that supports SLI for your CF setup.

Look closely x16/x4 vs x8/x8 is a pretty poor result averaging over 10%, not even worth it to go crossfire. Also that test is older, GPUs now push a lot more and has been shown to affect performance more.

If he doesn't get x8/x8 IMO its not worth the money.

Rogue Leader,
Can you recommend me a good motherboard that would work best with crossfire?
Thanks

What i5 cpu are you running, and if you're not overclocking why do you have a water cooler? What motherboard do you have now?

Intel I5 6600K
Gigabyte H110M-A
Deepcol Captain 120MM

Feel like overclocking a CPU is a gimmick. Doesn't really increase perf much and im scared to OC :/

 

[Rogue Leader]

Its definitely not a gimmick, but with that board it doesn't matter you can't overclock. It can increase performance somewhat, but no its not enormous gains like some would have you believe. But 10-15% is nothing to turn your nose up at.

With this one you can:

And its about the cheapest thing you can get x8/x8 slots on

Yes there are cheaper boards that will do Crossfire, but they are x16/x4 which is, as discussed, a waste of money.

Alright ill get that motherboard .... Looks like an amazing deal too. Thanks!

MERGED QUESTION
Question from Mac070 : "Good Mother Board For Dual RX 480's"

I need to find a motherboard with the LGA 1151 Intel socket that has the best crossfire support. IM running an I5 6600K and dont need to overclock it. I have a water pump (Deepcool Captain 120MM) ... Just need a suggestion on a motherboard with the best crossfire support. Anything under $120 will do ! Thanks

Any motherboard with crossfire support? Ideally one that has at least 8x lanes per card and not 16x/4x like on lower end boards.

Quick check shows you have a few dozen Z170 boards to choose from in your price range.

You'll need to narrow your choices down on some criteria.

Well could you recommend me one? That has the best crossfire support for my socket and flows with White and Black

Any Z170 board will support CF as long as it has 2 PCi-E slots. CF can run on as low as a 4x slot, so running on 16x/4x will still work for CF (sli has to run on a min of 8x) Since you have a 6600K you would be wise to go with a Z170 board just to give you the option for overclocking if you ever want to.


If you can up your price a little I would go with this http://www.newegg.com/Product/Product.aspx?Item=N82E16813130920

Pretty much all black: http://pcpartpicker.com/product/yLPzK8/msi-motherboard-z170asliplus

Color is getting us a little closer, but what else do you need?

Once you filter by socket, and crossfire, there are still tons of options. Size for example. Storage configurations, number of fan headers, onboard audio quality, wired and wireless networking options.

You really need to sit down and examine what you want to do now and what you might want to do in the future.

need m.2 slot.... atleast 2 fan headers.. thats all i can think of.

 

[Rogue Leader]

You started a new thread and found the same answer. That MSI board that has again been suggested has an M.2 slot and more than 2 fan headers. Its the best choice for you.

I know that was my fault! Thanks! I might save a bit more for the Krait cause its white.
