Yes it does have a memory multi x8 ...but when I set it to x8 my timings for auto go to 11-11-11 which is not correct for the G.Skill memory I have (9-9-9-24)....
The Gigabyte 880GA-UD3H only natively supports 1333...To get 1600 you must OC the CPU. http://www.gigabyte.com/products/product-page.aspx?pid=3520#sp
I believe if I overclock CPU I can get support for 1600-2000 for DDR3 RAM - http://download.gigabyte.us/FileList/Memory/mb_memory_ga-880ga-ud3h_v.2.1.pdf
I think this is why the timings screw up if I only set the Memory Multi to x8. It needs the CPU overclocked to get correct auto timings? I'm not reallly sure.
