I just did some swapping with a friend and I got a ASUS Crosshair V Formula AM3+ AMD 990FX MB.
All I had to do was just change the speed in the bios and I up and running with 4 sticks of Kingston 1866 with no problems.
So where did Gigabyte drop the ball on this one. I have the GA-990FXA-UD5 and I can't do it with 4 sticks of memory only with 2 will work.
Unfortunately their AM3+ boards are not wonderful ,but this aspect really depends on the memory sticks used as well in my opinion.
The BIOS involved is important as well ,they are not optimizing BIOS-es for AMD boards for some reason.
Not much revenue comes out of them or something.
Had satisfaction with my 890GPA-UD3 ,but the 970A-UD3 was not what i have expected as well.
Maybe they will do them better in the future.
And the competitor product has a huge price don t forget that
