It's definitely not a ram issue. I have 16gb of ram.. and I just installed windows freshly :D
 
Both bugchecks indicate memory corruption. If your system ram tests out ok with memtest then i would then be looking for a device driver that is corrupting system memory. Update all the drivers for your motherboard, update the bios or reset it to defaults if it is current. Confirm your ram timings are ok with memtest and see if you still be t the bugcheck. If you do, you will have to run verifier to force the system to bugcheck when driver writes to memory it does not own. The driver name will be named in the bugcheck.

Sorry I can not look at the minidump until I get back to a pc on Thursday. If you use verifier.exe (google for instructions) you might be able to use a automated memory dump reader to get the driver name, without verifier it will report the victim of the corruption rather than the cause of the corruption.

You will also want to confirm your windows copy is good. Service packs installed, updates installed. Run the system file checker. Run cmd.exe as an admin then run sfc.exe /scannow and a malwarebytes scan.

I figured out the source. It's the ExpressCache of the system. After disabling the EC, it's running smooth without any BSODs.
A few months back I tried to install Windows 10 and formatted all partitions. I accidentally formatted the SSD for the expresscache.
So I tried formating it back to the required version.
I also tried using OEM system restore to restore the laptop back.

I tried downloading the drivers from Samsung's website but still having the same issue.
