Computer Beeps after adding additional memory

[ItayK]

While surfing the InterWebs searching for my problem,I saw someone suggesting using only the new RAM.
So I disconnected the old RAM,turned on the computer and guess what,it works.
Now my question is,what do I do in order to use both of my old RAM and my new RAM?

Happy new year !!!

Edit: I gave you the URL instead of the Perma link .... that shows how stupid I am ! sorry ! 😀

Edit: The new RAM is the Hyperx and its ddr3 1866 !
The old RAM is the Geil and its ddr3 and I think its 1333(bought it 2 years ago).

all the ram is the same? sam brand and model?

the one you list is ddr3 1866, the other is ddr3 1866 or 1333 perhaps?

then, with the 1866 connected, in the bios/uefi, you must force the new ram to 1333

then put the other

personally i wouldn't put the 1333 back, seel it or donate it and buy another 1866 ram stick, same brand and size

the 1333mhz ram is slow, more ram but slower is not a good idea, more ram as fast as possible is a good idea

Fun thing is,Amazon sold the exact same one at 1600 and 1333 but they were all at the same price as the 1866,so I went for the 1866 obviously...
Oh well,I guess I will try to sell it and buy another one of those...
Thanks a lot man !
