Lenovo Ideapad 310-14ISK 80L RAM and HDD upgrade

[TEDDYKGBBEAR]

Hi
Im looking to upgrade my Lenovo Ideapad 310-14ISK 80L and i have read manuals (two of them provided slightly different information) and also some general questions that i would like an answer from someone who is familiar with this particular model.

First, i want to upgrade RAM and all i know is that there is DDR4 4GB(different from what manual says). from CPU-Z test
CPU-Z also shows that NB frequency of current RAM is around 2700MHz and DRAM frequency is 1064MHz
From manual i find out:
Type and speed: DDR3L-1333 MHz/1600MHz
max supported capacity: 16GB / another manual sayd max 12GB
Slots: SO-DIMM x2

What i do not know is what type of RAM shall i choose/machine supports.

I guess since CPU-Z pulls real info from PC then i shall choose DDR4 for free slot
But there is 2133MHz and 2400MHz memorys available, which one is best for this laptop?
As for size i guess i will try out adding another 4GB and taking from there.


Second question is about HDD, current one is 1TB HDD and also i have available extra bay for 7mm HDD only where usually is cd-drive.
I want to take out HDD and replace it with SSD and put HDD into extra bay, will this model be able to manage two drives simultaneously, SSD as main one with OS and HDD for extra files?
As i understood i need to replace HDD with SSD and make a clean OS install on to SSD(already prepared USB installation media) and after everything is done and booted into windows then i will connect HDD into extra bay but should i prepare HDD somehow or it is simple as plug in and go?
Is there anything else i need to consider as im planning to do all this by myself rather than let someone do it for me.

All info and tips much appreciated
Thank you

If you go to a memory vendor like Crucial, you can plug in your laptop model and it will list all compatible RAM for your system. There is not much if any price difference in purchasing the RAM from Crucial than anywhere else.

The drive update, if the drive bay accepts your hard drive, it should work with both drives. Install the new drive with the old one removed, install Windows on that new drive, plug in the old drive to the secondary bay, and all set. You can then format the second drive if you want to wipe it, but it's large enough where you can just keep everything on it as a backup. Of course do not wipe the drive if your files are still on there.
