Hello, i have 16gb of corsair ram ( https://www.amazon.ca/dp/B00SV7IILC/ref=cm_sw_r_cp_apa_i_eYwwFbKSMYKB3 ) with a xmp profile at 2400mhz and i would like to buy this set ( https://www.amazon.ca/dp/B07MYCT6RL/ref=cm_sw_r_cp_apa_i_vZwwFbK167XNE ) because 2400mhz is getting kinda slow. So i was wondering if it would be possible to combine the two to make 32gb of ram (so 16gb of 2400mhz and 16gb of 3000mhz) ? I heard that the 3000mhz would only run a 2400mhz or it would simply not work. I have an i3-9100f and a Gigabyte Z390 M Gaming mobo. Thanks. Sorry for my English.

When mixing different make, model and speeds you have 3 possible outcomes:
  1. It will function perfectly at the slowest common speed and timings ,(in your case could even be 2133 MHz)
  2. It will function, but be instable
  3. It will even not boot
And nobody can precisely predict the outcome

13 9100 16 GB is enough, many factors affect slow depending on the application you are using games, graphics, rendering, the impression of being slow is just a feeling. no need to add ram if different spec. wear it with pleasure it will be fast

There are a few rules when mixing ram

obvious one is to get same type of ram like ddr4 or ddr3 etc
Try to get the same speed (if you do not match it will scale down to the slowest ram stick)
Try to get the same "CL" - download cpu-id and go to the ram tab, and find what is next tos CAS latency
try to stick to the same brand

While not guaranteed that it will work, this will greaty increase the odds in your favour

In my personal experience it usually works
