HP 15-ac122TU
Microsoft Windows 10 (64-bit)

I purchased a RAM chip having the following specifications - 4 GB , DDR3L , 1600 Mhz , SO-DIMM , 1.35 V , for my Notebook HP 15-ac122TU, which already has 4 GB pre-installed RAM.  I installed the RAM chip in the 2nd slot of my notebook. But Windows 10 doesn't detect it. The installed RAM still shows up as 4.00 GB instead of 8.00 GB. I also tried msconfig and restarted it. But still it doesn't show up. Please help!
