Both motherboards and CPUs have RAM (memory aka DIMM) speed limits. Your true speed limit will be the lower of the two. That being said, you may be fined with 2133 MHz depending on what applications you use. If you’re a gamer, you’ll usually buy a “performance” grade DIMM.

1Is there a RAM speed limit for motherboards?
So, although a motherboard can handle up to 2133 MT/s (Megatransfers per second) DDR3, most CPUs will not be able to handle that memory speed by default. Certain models of CPUs also support more advanced ECC memory like those found in a server or workstation.
We’ll take a look at an older generation i7-2637M to show some similarities in CPUs. On the Intel® website, scroll down to the memory specifications section for the CPU, where it only supports up to 8GB of total memory and DDR3 speeds of 1066/1333 MT/s.
2Does motherboard affect RAM?
The more RAM you have installed, the more applications your computer can process at a time and run at a faster rate. Your motherboard’s settings will determine how much RAM it can handle, but 4GB is the recommended amount for most users.
3Can RAM speed be incompatible with motherboard?
Since each type of memory has different notch locations (which are critical for installation), different memory technologies aren’t always compatible with each other. Motherboards are generally only able to handle one form of memory technology.
4What limits the speed of RAM?
The computer’s speed and the bus speed are the limiting factors in determining the speed of RAM installed in your machine. RAM upgrades are limited by the computer’s capability and the availability of expansion slots for adding RAM.
5Can I use 3200MHz in 2666MHz motherboard?
Yes, you can, but your other ram, which is 3200 Mhz, will slow itself down to 2666 Mhz to remain in sync with your slower RAM. It will have no effect on your overall system’s performance, but it will have more RAM.
6Can 3600MHz RAM run on 2666MHz motherboard?
I’m guessing you’re asking if you can use 3200MHz or 3600MHz RAM with a CPU that has been optimized for a maximum RAM speed of 2666MHz. Yes, but it is pointless because you will only get a maximum speed of 2666MHz out of the RAM.
7Is RAM speed based on motherboard or CPU?
The motherboard dictates the RAM speed. Even if you use 2400MHz RAM, your motherboard will bring it down to whatever it is rated at.
8Do I need to change my motherboard if I change my RAM?
A motherboard that will support those new RAM modules is required to make the switch to the latest iterations of RAM. For example, if you’re currently using DDR3, you won’t be able to switch to DDR4 or the latest DDR5 without swapping out the motherboard and CPU first.
9Can a motherboard limit performance?
Motherboards May Limit Your Component Performance According to the highest performance level that the motherboard supports, it is possible to have two different motherboards that support the same CPUs, GPUs, RAM, and SSDs, but not both.
10Can I use 1600Mhz RAM in a 1333MHz supported motherboard?
Can I use 1600 MHz RAM in a 1333 MHz motherboard? Yes, you can use it, but you won’t be able to use 1600MHz because your motherboard supports 1333MHz.
11What happens if my motherboard doesnt support my RAM speed?
Both RAM modules will run in the slower mode on the motherboard. If the RAM had that capability, it would only slow down clock.
12What happens if you use faster RAM than motherboard supports?
If you try to build and use a RAM module that does not support the CPU and the motherboard, it will result in unstable system performance and/or boot issues. Mismatched memory will do this as well.
13Why is my RAM speed 2133 instead of 3200?
Your motherboard may be that it isn’t designed to handle the speed of 213-However, it could be that there is a setting in the BIOS that you need to change to make it run faster.
14Why is my 3200MHz RAM at 1600?
Probably because your CPU or motherboard does not support 3200MHz RAM in the configuration you’ve chosen. Since DDR stands for Double Data Rate, the RAM clock frequency of DDR-3200 is 1600MHz. The data runs twice as fast as the clock.
15Why is my RAM not running at full speed?
If your CPU does not support the XMP profile, your RAM will only run at the maximum speed allowed by the CPU. E.g. If your RAM has an XMP profile of 4000 MHz and your CPU only supports memory speeds up to 3200 MHz, your RAM will only run at 3200 MHz. It’s the same deal with motherboards.
