RAM Upgrade causing boot issues

HP Recommended
HP Notebook - 15-db0997na
Microsoft Windows 10 (32-bit)

Hi, i have a "HP Notebook - 15-db0997na" and decided to upgrade the RAM from 4GB to 8GB.  I purchased "KingFast DDR4 4GB 2666MHZ 1.2V) from local PC repair shop and inserted in to the laptop and the upgrade worked OK, however a few days later the laptop will not start up.  The CAPS LOCK key flashed 3 long flashes and 2 short flashes.  I checked the support page and it provides the following "The embedded controller times out waiting for BIOS to return from memory initialization.).


I removed the new RAM and now the laptop starts up.


Why does the upgrade no longer work.


Is there a fix for this.


I appreciate any help

The memory is not compatible. Its CL11 latency and you need standard DDR4-2400 SO-DIMM which should be CL=17 latency. Like this:
