Can I install a different frequency ram on my system?

[Chaehee]

Aight, I recently put together my system, and I got myself a pair of HyperX Predator RGB, 8GB, 2933MHz, DDR4, CL15.

But then, I am planning to get myself another pair of ram, and I wanted to get a higher frequency one, had my eyes on HyperX Predator RGB, 8GB, 3200MHz, DDR4, CL16.

My question is, can I use them together? or would I need to replace my kit entirely? (I assumed that since they work in dual channel, my 2933 rams populating the 2nd, and 4th dimm slots. I could just install the 3200 mhz rams in the 1st and 3rd dimm slots and they would work fine?)

few more info about my system:
CPU: i9 9900k

Mobo: Z390 M Gaming (Gigabyte)

They would run at 2933

First off, you can't. Second off, there is absolutely no performance difference between 2933 and 3200. Believe me, you might see some things in certain instances but in the majority of times, there's no difference and just not buying one far outweighs the benefits assuming if you did buy one. So, my suggestion is first off, no it wouldn't work. And second off, even if it did or you got an entire new kit then you probably wouldn't notice. 
Don't buy it. 

Cheers.

Wrong advice and information. You can totally run different sticks together of different timings. They will just run at the slowest timings of the sticks. You can manually tweak and overclock them as well to tighten things down even more. Go do some research before giving bad advice and information like this.

this is wrong. the faster ram would be downclocked to match the frequency of the slower ram i.e. your 3200mhz ram would run at 2933, as said by enderman.

also wrong. ryzen chips benefit from higher clocked ram due to their infinity fabric design. but if you're running an intel chip the difference would not be noticeable during daily use (maybe 10 more points on cinebench)

Honestly with a 9900k, the only thing you would really benefit from is having 16GB of ram. With intel there would be no noticeable difference between 2933 and 3200 but upping it from single channel 8GB to dual channel 16GB would be a big step up.

 

Edit reread the post noticed you plan on using the Ram modules together to equal 16GB, usually it works with the frequency of the 3200 downclocking to the speed of the slower module. Sometimes it can be iffy using two different modules that weren't purchased together sometimes they work fine, but other times they have incompatibilities. I usually just recommend to buy a kit so you know without a doubt they won't have issues together.

That's what I meant. Sorry for wording it incorrectly.

I understand Ryzen chips may benefit from this but he has an Intel chip which is exactly why I said this? So why are you even mentioning that?

i was simply correcting a mistake you made. you stated that "there is absolutely no performance difference between 2933 and 3200" which is misinformative. if you had omitted the aforementioned statement, then there would be no reason for me to comment (apart from the other mistake you made where you said 2933mhz and 3200mhz ram are incompatible).

the only reason why I claimed there was no performance difference was because he was using an Intel CPU, otherwise I wouldn't have said that.

noted. however, your claim was misguided. please do more research before posting inaccurate and unwanted information.

I just misworded myself. My apologies.

Ooph if this was the case I would be in a ton of trouble right now as I have 2 RAM kits in my PC each with different speeds, and my MOBO is not even capable of supporting the fastest advertised speeds of either kit.....
