you can try. sometime work, sometime don't

Sure you can , but even if it's identical , there's still a small chance it won't run with the other 8gb. module.

why wouldnt it work? does 24gb of 16 + 8 have problems?

In the beginning, there was......BIOS Before you go ANY further, go to the manufacturer product page for your specific motherboard model AND revision. Revision is an important aspect because for any given motherboard there may be more than one version of that model which will be identified...

A motherboard must manage all the ram using the same specs of voltage, cas and speed.
The internal workings are designed for the capacity of the kit.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, can be very sensitive to this.
This is more difficult when more sticks are involved.

Intel is fairly tolerant of disparate ram. I might guess that your odds of success are perhaps 85%.

If it all plays nice, the matching 8gb in each channel will operate in dual channel mode.
The odd 8gb will operate in single channel mode.
