Lenovo G40-45 RAM speed problem

So I recently upgraded my Lenovo G40-45 (specs below) from 4Gb stock RAM to 8Gb. 

The new ram that I installed is Kingston KVR16LS11/4 in 2X4Gb configuration. 


After looking around for the specification of my laptop model on the lenovo website, I read that if I use both ram slot for this laptop model, the ram speed will run at 1333Mhz, but if I use a single slot, it will run at 1600Mhz.


Given that my newly installed ram have a clocked speed of 1600Mhz each stick, I thought that the laptop will auto-config the speed and run the ram at 1333Mhz, but after checking on CPU-Z and Task Manager, my ram only runs at 800Mhz. 


I know that my CPU doesn't support dual channel mode, so I don't have a problem on that, my only problem is the speed that it's showing on CPU-Z and Task Manager. 


I have included screenshots of my task manager side by side with CPU-Z. 




Can someone help me on this? Thanks in advance.


EDIT: I think I know now why it's 800Mhz in CPU-Z, but if you have another explanation please tell me. The only thing that bothers me now is the speed in the Task Manager, I saw some PC with 1333Mhz speed on that, so why is mine only at 800Mhz?


Laptop Specs:

Model: Lenovo G40-45

CPU: AMD A8-6410 with AMD R5 Radeon Graphics

RAM: 2X4Gb Kingston KVR16LS11/4 (@1600Mhz each stick)
