RAM incompatibility in dual channel?

HP ProBook 440 G5
Microsoft Windows 10 (64-bit)

Hello,

in my laptop is installed this RAM:

Memory type DDR4
Module format SO-DIMM
Module Manufacturer(ID) Samsung (CE00000000000000000000)
SDRAM Manufacturer (ID) Samsung (CE00000000000000000000)
Size 8192 MBytes
Max bandwidth DDR4-2666 (1333 MHz)
Part number M471A1K43DB1-CTD
edited.
Manufacturing date Week 43/Year 18
Nominal Voltage 1.20 Volts

 

and works flawlessly.

 

When I bought and installed:

Memory type DDR4
Module format SO-DIMM
Module Manufacturer(ID) Samsung (CE00000000000000000000)
SDRAM Manufacturer (ID) Samsung (CE00000000000000000000)
Size 8192 MBytes
Max bandwidth DDR4-2666 (1333 MHz)
Part number M471A1K43DB1-CTD

Manufacturing date Week 45/Year 18
Nominal Voltage 1.20 Volts

 

which I assummed was the very same module, the system crashes, there was data corruption on my SSD, and this configuration does not pass any test.

When I test each module individually, there is no problem. When I put both into my laptop, whichever slot, it starts malfunctioning after some time.

What could that problem be possibly caused by?

 

Thank you.
