Your Motherboard May Not Support It Some motherboards are simply not designed to handle RAM speeds over a certain threshold. Take the above board for example. Its maximum RAM frequency is 3466 MHz. If you bought a DDR4 RAM kit that boasted of 4000 MHz, it would not start at that speed if you used this motherboard.

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 my RAM speed have to match my motherboard?
Make sure your memory is compatible with your motherboard. Compatibility is the most significant factor in buying a memory upgrade for your machine. Memory must be compatible with your motherboard in order to work on your machine.
3Does 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.
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.
7Can I use 1600Mhz RAM on a 1333MHz board?
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.
8What happens if I use RAM of a faster speed than the 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.
9How do I know what speed my RAM is compatible with my motherboard?
The fastest way to find out if RAM is compatible with your motherboard is to check your motherboard’s Memory QVL list. On the manufacturer’s website, look for a page or section labelled “Memory QVL” or “RAM support list.”
10Can faster RAM run on slower motherboard?
As long as the faster RAM is of the same model that the motherboard supports, it will likely work. In other words, if the motherboard supports DDR3 RAM, it will work with faster DDR3 RAM. But you can’t put DDR4 RAM in a DDR3 motherboard.
11Do 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.
12Does RAM depend on motherboard or processor?
The processor, the operating system, and the motherboard all determine a computer’s maximum supported system memory, or RAM. The maximum amount of RAM a computer can handle is determined by these three variables, as well as hardware and software limitations.
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.
14Is RAM speed limited to processor?
Yes and no! Ram speed is limited by the processor, and each processor has a different supported stock ram speed. That 2666 is the processor’s stock ram speed, not overclock, nothing, completely stock.
15Why is my 3200MHz RAM at 1600?
The module’s main speed will be 1600 MHz in CPUZ, but the final speed is 3200 MHz because DDR doubles the data rate. It’s nothing wrong with your modules.
