My HP Laptop has “DDR4-2666/PC4-21300 DDR4 SDRAM SODIMM” (4GB) in one slot, Can I put “DDR4-2400 SODIMM” (8 GB) in next ?

I have HP Laptop 15-bs1xx ? It has Intel Core i5-8250U Processor on HP 832A Motherboard.

It has two memory slots. In one, as per HWinfo tool, I have "DDR4-2666 / PC4-21300 DDR4 SDRAM SO-DIMM" 4GB.

I want to expand my memory.

I saw a cheap 8GB memory ( Crucial 8GB DDR4-2400 SODIMM CT8G4SFS824A ) online. It is "DDR4-2400 SODIMM". Would this be compatible with my HP laptop ?

Please Help ! I don't want to end up with the wrong RAM.

But if I put 8GB 2400MHz, will it slow down my existing 4GB 2666MHz RAM. I heard somewhere that speed should match otherwise the other will slow down. How significant is the difference.

At best, it will downclock to the slowest.
At worst, of course, it is simply not working at all.
