I have an old Samsung rf411 notebook and upgraded its memory from 6gb (1x2gb and 1x4gb) to 8gb (2x4gb). The new memories model are Corsair Value Select - CMSO4GX3M1C1600C11.
When the memories arrived, I realized that they have a different frequency from its original pack. My notebook supports only 1333mhz memories, and the new ones runs at 1600mhz. I've read some comments that this it's not going to be a problem, but I now realizing that my laptop is overheating more than before.
I didn't find a way to change the memories frequency in the bios (see the following images please).

What should I do? Try to replace the memories to 1333mhz or configure the 1600mhz to run at a lower frequency? If so, how can I do this? I researched a lot and didn't find out a way to perform this at my bios or at the Ubuntu itself.
It's common for a laptop BIOS to be pretty restricted. You will probably not be able to change the frequency. You could try to use your 4GB 1333 stick as usually the slowest speed is used. – Seth – 2017-10-17T11:17:44.000
Are you trying to find out why your laptop is heating, or how to modify your bios to force your ram to run at a lower speed and voltage? – None – 2017-10-17T18:00:56.427
@Zymus, do you have any suggestion in how I can perform the downgrade in ram speed and voltage? My laptop is a Samsung rf411, and I don't have this option at my bios configuration. Do you know if it is possible to do it at the OS level? Running Ubuntu 16.04 here. Thanks! – João Paulo Navarro – 2017-10-18T00:17:38.940
Have you tried putting the old ram sticks in to see if it still overheats? – None – 2017-10-18T00:43:09.823
