How to decrease ram speed from 2666mhz to 2400mhz?

System- hp prodesk 400 g4 mt business pc

Bios- hp P03 system firmware 02.35

The system came with ddr4 4gb 2400mhz ram. I wanted to add another 4gb.

 

The store didn't have 2400mhz so i went with 2666mhz. But when i installed i realised that the motherboard only supports upto 2400mhz. So the computer is showing (in the photo i attached)installed memory as 8gb but the total memory is still 4 gb and i am only able to use 4gb. 

 

So i was wondering if i can decrease my ram speed to match the 2400mhz speed? Or any other solutions to my problem?

Edit: i did try to reinstall ram but problem still exists.

 

Any help or any suggestions will be much appreciated 🙂

It doesnt have anything to do with frequency or the fact that they arent matching sticks. Just take the new stick out and put it back in (basically reinstalling it).

You can’t. Even if it could support 2400MHz+ I wouldn’t underclock it. Go back to the store and see if they have 2400MHz RAM

If you install RAM with different speeds, the faster RAM will automatically run at the speed of the slowest RAM in the system, so I don't think that's what's causing the issue. 

But unfortunately my motherboard doest support 2666mhz but only till 2400mhz. Thanks for replying
