Beeps when upgrading ram for HP OMEN Obelisk 875-1001nx

[Gotah]

Dear experts, 

I tried to add an additional ram stick to the official one that came with the PC, but it keeps beeping when turned on (3 long beeps followed by 2 short beeps).

The ram stick I have added is HyperX Fury 16GB DDR4 (HX426C16FB)

The ram stick already exist is HyperX Fury 16GB DDR4 (HP26D4U9D8ME)

I tried all slots and make sure it is inserted properly still same issue, i also tried each one separately, the new one seem to be refused by the PC for some reason.  I don't know if its incompatible or is it faulty? please help.

Hello
there are not 36 solutions.
If the module does not work with the original one, and no longer on its own, either it is incompatible or defective
Have you tried all the locations with the new one alone?
