1600 Mhz DDR3 ram only show up as 1333Mhz on Bios

just because a ram stick isn't listed on the QVL doesn't mean it won't work, but having two from different mfgrs and completely different values is fairly certain to not work. YOu'd be smart to sell those and buy a matched set, hopefully a part number that is on the QVL list

a matched set when you see two in a package, ie two 8GB sticks together - not just buying two of the same part number, ie single sticks

fwiw

Hi, thanks. i tried to run with only the 1333Mhz stick, turn on overclock, but still get the same 1333Mhz like in the Bios picture.

i'm not ram literate enough to know, but your jedec values in #5 & #6 are different from the first stick

they're obviously not matched - two different part numbers. Did you make sure both sticks are on the asus QVL (qualified vendor list)? And frankly even if they are, they should at least be the same part number

they should be bought in matched sets - you can get lucky sometimes but need to stay with same mfgr and model #

if you want to replace both sticks to increase ram, make sure whatever you buy is on Asus QVL list for that board - here's the link https://dlcdnets.asus.com/pub/ASUS/mb/LGA1150/B85-A/H87_Series_Memory_QVL_Report_0306.pdf

and this is the closest to the part number on the working one:

if they are not rated to work together on the same channel then can they be working in different channel? just newbie question LOL
