Speeds are multiplied because of DDR, which stands for Double Data Rate.

I only have xmp 1.2 profile 1 in the bios thats the only one listed.
I changed DRAM Freq to DDR3-1600mhz

On the Memory tab in cpuz its saying 800 mhz which if its doubling should be correct
Although on the SPD tab slot 1 and 3 say pc3-10700 (667mhz)

it gets a lower rating in windows test than my gskill ram in other computer which
is 8gb 1600mhz also. :(  thats why i started looking into it in the first place to make
sure that its running correctly.

Yes, if Cpu-z shows it as 800MHz it is working at 1600MHz, you're fine there

ok I reran windows assessment and the RAM score went from 7.6 to 7.8 so I think that did it, thank you guys for your help :D 
although it still saying max bandwidth is 667 mhz in slot one idk whats up with that
but i dont know much about ram speeds either really, thanks for your help
