Ok so I am currently using a Phenom II x4 955 at stock settings. My motherboard is an ASRock 890fx Deluxe 3 board. For memory I use G.Skill DDR3 1600mhz ram (2 sticks of 2GB each). When I look at CPU-Z, under the memory tab, it says that I have a max bandwidth of "PC3-10700 (667mhz)." This confuses me because I have already set my ram to XMP-1600 in the BIOS. I understand that since it is dual data rate, it runs at 800mhz, but shouldnt cpu-z say that i get "PC3-12800 (800mhz)" for max bandwidth? Any input would be awesome
What CPU are you using? I know that we are in AMD land, but let me give you an Intel example. I have DDR3-1600 memory on my Asus P7C55D Deluxe which supports it, but with the Core i5 2.66 Ghz model it throttles down to -1333.
