Solved AM3 SLI MB ( x16/x16 ) Tags: Motherboards Gtx Bottleneck SLI Product Last response: July 25, 2010 5:44 PM in Motherboards Share CtrlAltDefeat July 25, 2010 12:09:45 PM I'm looking for a good AM3 mobo that supports SLI and preferably can run dual x16/x16 ( I plan on SLI-ing two GTX 460's, I don't even know if x8/x8 will bottleneck it, will it?). Is this http://www.newegg.com/Product/Product.aspx?Item=N82E168... a good one? Or at least a decent one? I hope it is, because it looks like it's practically the only one . More about : am3 sli x16 x16 jasobnd July 25, 2010 1:11:20 PM Its good for what you want, perhaps look into the ASUS Crosshair 4 http://www.newegg.com/Product/Product.aspx?Item=N82E168... alot more expensive but the best you can get if your willing to splash the cash. If you notice on the right hand side of the page there is a "specifications tab" if you look for this on any website youll be able to see if it supports x16 x16 lanes. And yes x8 x8 will bottleneck the card as it only works at half the capacity. I stupidly installed my 5770 in an 8x lane and it was slow as anything. when i moved it up it was proper fast. mindless728 a b V Motherboard July 25, 2010 4:29:36 PM @jasond, that board does not support SLI (which is what he needs) really there are 2 choices, one for dual SLI and one for up to triple ASUS M4N98TD EVO MSI NF980-G65 AM3 the MSI that does the triple SLI goes from x16/x16 to x16/x8/x8 for triple, but with the GTX460's it won't be a problem (you need something like the 5970 or GTX480 to see the x8 bottleneck) Related resources Cheapest x16/x16 motherboard for 1155 SLI ? - Forum Gigabyte Z68-UD7-B3 wont run sli x16/x16 - Forum SLI 580 and Z68-UD7-B3 not running x16/x16 - Forum CF/ SLI @x8x8 vs x16x16 - Forum What's the difference between running CrossFire on x8/x8 and x16/x16 ? - Forum Can't find your answer ?

Anyway, I'll be fine with the Asus one right...? It's a good mobo?

Anyway, I'll be fine with the Asus one right...? It's a good mobo? it's a two fold reason probably, one because AMD owns ATI and because with LGA775, NV stopped making a lot of chipsets for AMD since they didn't have the enthusiasts market yeah, the ASUS should be fine, and i didn't even notice that the GTX460's can't be used in tri-SLI i am so used to ATI doing tri-quad almost anything mid range and higher CtrlAltDefeat July 25, 2010 5:44:18 PM Best answer selected by CtrlAltDefeat.
