You may have a problem.
Ram is sold in kits for a reason.
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, particularly AMD can be very sensitive to this.
This is more difficult when more sticks are involved.
That is why ram vendors will NOT support ram that is not bought in one kit.
It is safer to get what you need in one kit.
But, it is a bit more expensive because of the added matching of all the sticks to insure compatibility.
What to do:
1. Buy a second 8gb stick and hope that it works. Your odds of success are less than 100%.
Perhaps 90% for intel, less for amd, particularly ryzen.
What is your plan B if it does not work??
Either you run with 8gb single channel or you sell both and start over again.
2. Buy a compatible 2 x 8gb kit similar to what you now have if possible.
You want documented ram compatibility. If you should ever have a problem, you want supported ram.
Otherwise, you risk a finger pointing battle between the ram and motherboard support sites, claiming "not my problem".
One place to check is your motherboards web site.
Look for the ram QVL list. It lists all of the ram kits that have been tested with that particular motherboard.
Sometimes the QVL list is not updated after the motherboard is released.
For more current info, go to a ram vendor's web site and access their ram selection configurator.
Enter your motherboard, and you will get a list of compatible ram kits.
Be careful, Ryzen is very picky about compatible ram.
Then, if your motherboard permits, try your 8gb stick.
If it works, good; you have 24gb.
If not sell the old stick or keep it as a spare.
