Quick question: Mixing Memory Speeds

[Jirne]

Just a very quick question from someone who's been out of the PC-building space for a bit and can't quite remember.

 

I'm running 16GB of 2133MHz-DDR4. 16Gb because back when I built this PC that seemed to be enough and 2133 because it's and Intel system and back then, this was the cheapest set from a reliable brand (Kingston HyperX) I could find here in Belgium.

 

Now I'm frequently running up to 14 and 15 gig's of RAM usage and am considering adding another two sticks (thank god I bought a board with 4 slots) but 2133 seems to no longer be very available... at all

So now here's my question:

Can I buy a new set of faster RAM, throw it in and expect it to work? I don't mind if I have to downclock the new RAM to 2133 for the bit of speed loss that causes. But I don't wanna throw in some RAM only to find out I can't even get into the BIOS to downclock anything  

Also, would I even need to downclock it? Do timings matter? Used market here for PC components is basically non-existent to selling it off and buying 32gigs of new RAM or buying used 2133 is really not an option.

You can buy very fast ram, for example 3000 Mhz , 3200 Mhz ,3600 Mhz.  Y

You can combine it with your 2133 Mhz memory but your motherboard will run all sticks at 2133 Mhz.

 

There's a high chance those HyperX sticks will run at 2400 Mhz if you raise the memory timings a bit and maybe the voltage.

For example, if the SPD profile  (you can see the profile with freeware CPU-Z) says 1066 Mhz CL17 1.2v , the stick may work just fine at 2400 Mhz CL19 with 1.25..1.35v

It's technically overclocking but it's fairly safe overclock.

You're overthinking it. You will always have the speed of the slowest part. There is no need to change anything. Just put them in and boot the system.

quick question. can mix difference types of ram sticks. example Team Group T-force R and Corsair Vengeance RGB Pro?

[mariushm]

ram is ram ... of course you can.

motherboard doesn't care who made the ram.

 

As long as the ram sticks are all the same type supported by the motherboard (regular unbuffered ddr4, without ecc) it will work.

Alright thanks for the info. Is there any problems mixing capacities? 2x8 + 2x16?
