Windows 10: 2 x 8GB RAM DDR3 HP Pavillion 15

Hello..I have a laptop HP Pavilion 15 running in Windows 10 Pro. Originally there is 1 x 8GB DDR3 ram installed on it. I upgrade it by adding another 8 GB Ram DDR3 with same speed 1600mhz on the second slot to make it 16GB total RAM. When I check the memory status on the task manager the Total memory become 16GB however the memory slot used is showing "slot used: 1 of 2" only. I just want to know why it showing only 1of2 instead of 2of2 since both slot has memory stick installed? it does mean only 1 memory is working? but why it shows the correct sum of memory? I tried to run also memory test

HP Pavillion Power 15" Windows 10 Freeze

My Laptop keeps freezing once in a while. Once it freezes, it will stay frozen until i either unplug my charger or replug my charger.

I am still unable to fix it, but here are some input.

Laptop: HP Pavillion Power 15"

Some symptoms:

• Ram is around 80% usage or higher
  
• The computer does not lag
  
• This happens less frequently after restarting and happens more frequently the longer I kept the laptop on or without shutting down (sleeping and turning on)
  

Thing's I have tried to change:

• the max cpu power in the power management
  
• the power plan
  

 

single channel ddr3 vs dual channel ddr3

I've got two 10 year old laptops and I'm upgrading the memory to 8GB. On Speccy it's currently reporting the RAM as

HP: DDR3 Single channel PC3-12800, 2 slots both used
Toshiba: DDR3 Dual channel PC3-10700 2 slots one used

I'm confused so please correct me if I am making the correct assertions below. BTW I'm buying the ram secondhand off of Ebay and not buying from e.g. Crucial as too expensive otherwise I would use their memory wizard and be done:

ASSERTIONS:

1. The HP has a single channel memory architecture on the MB but the Toshiba has dual channel architecture on it's MB.
2. Any DDR3 SODIMM will work so I could use PC3-12800 on either laptop using a 2 x 4GB config.
3. Dual and single channel refers to the MB design and not the physical structure of the memory sticks. But if the memory sticks are labelled dual channel it means that they are designed to work with second paired memory stick in the appropriate channel.

Many thanks for any help in setting me straight if reqd
